👤The cable length for the Honda Z50 was too long so I had to route it under the seat so it would fit. The screws for the throttle assembly were not correct and they pulled the threads out of the metal. I had to find bigger ones. I had to use a grinder to cut the grooves in the cable for the brake lever because the cut out area for the cable was not made right. I would have returned the bike if my kids were anxious to ride it. Buying the least expensive part was a bad idea.

👤It seemed like everything was cool at first. It was ok to install. The first day the throttle cable snapped, we had to order a new one. I don't know if it was a user error or junk.

👤The cable broke after a few rides.

👤Got a mini bike. It's easy to install.

👤The handlebars on the Honda trail 90 need to be simplified. Everything seems to work well.

👤It worked, had issues with the cable coming undone.

👤The product is not as advertised, but it is too small. I would like to get the correct product. Sincerely. Rita J.

👤The product has bolts for installation. If you buy a212 from Harbor Freight, you need FINE THREAD bolts to install, because the bolts provided are 5/16th Coarse Thread. The coarse thread bolts that come with it won't go in more than a cm. Pick up 1” 5/16th FINE thread bolts from the store.

👤If you keep the Torque curve in tact, you can ride up hills and around the track faster, when you hit the hard pack the engine will take over and you will be able to top speed in a shorter distance. It's more predictable and engaging with the converter, even though some top speed is lost.

👤Looks good. The cart is assembled. I had to disassemble because it was a motorized bike. It won't work for a motorized bicycle. There is a mount shaft. But won't fit. Not big enough to fit there. Can't use it. Other than that. Its ok.

👤The grate on the motor cover could have been better. The kids go-kart moves at 25% clutch with my 200lb butt at 15-20 mph.

👤This item is used to power a senior scooter. The seller made good on his promise and I am satisfied with the result. Excellent service and communication.

👤The bulge in the backing plate is caused by the lower bolt for belt cover resting against the frame, so we had to grind it down. I am happy that my little man lives his buggy and enjoys driving it. I want to buy it again.

👤I had to lift my engine up to install the wheel. One wheel drive gokart.

👤Half of the hardware is missing. There was no spacer. There are no lock washers. The bolts wouldn't thread makes me believe they were the wrong ones since they aren't the same ones in the picture.

👤The Princess Auto is an electric start engine. The fit is nice. We can get weird stuff from Canada. The metric bolts that were supplied to bolt the TorqueConverter to the engine fit well, but the crank shaft bolts that were supplied were too short. You will need to buy a separate bolt to attach the clutch to the crank shaft. I would be surprised if the clutch system was manufactured in the same factory as the ones that came before it. The supplied belt seems cheap so I plan on replacing it. I will update this customer review if the clutch does not hold up.

3. Bikehand Bicycle Repair Torque Wrench

Brand: Bike Hand

👤I only write reviews about products I think are deserving. I can honestly say that I'm more impressed than I thought I would be after using the Bikehand repair tool kit. I've used every single tool that I've had the pleasure of using. It's even better to think I only paid $170 for it. If I spent $170 on Park Tools, I would be short at least 1/2, but up to 1/3 of the kit. I can't believe they included all the tools they did into the kit, and still have it retain the quality it does, and that is to include the case as well. There is a It would be a mistake to leave out the case quality, because every tool I've taken out has snapped back into place. Bikehand nailed the quality and didn't undermine a major component in which they easily could have done. I can confidently say that this kit delivers confidence. Every time you whip it out, you can be sure that you have the tool you need. The tool you pick up will be quality. Do yourself a favor and stop researching. This kit is for sale. For the record, I did not buy off or reimburse anything for this review. It is my honest review.

👤The case is banded in one corner, so I gave this tool 4 stars. It looks like it was dropped in the warehouse, but the tools are perfect. Since I don't care about that banded corner, I will keep it, but I would expect better packaging and handling. There is a The tools I tried to tune my bike with were awesome. You can get almost everything you need to fix or tune your bike at home for less money than Park Tools. I just tightened the seat post to 5 nm with the Torque wrench, it is not as precise as the more expensive ones, but it is still usable. It clicked perfectly. The brake calipers were secured to the carbon fork and it was safe for carbon. The cassette removal tools work as expected. There is a Do yourself a favor and get this set for 199$. It will make you happy!

👤The tools are well made and should last a long time. I completely changed my speed. The tools were useful, but I still needed other tools to complete the job, so I got four stars. I bought spa 1 and 2 from park tools as I was not sure which I needed but I am a tool junkie anyway. The kits fault was not the fact that the cassette removal didn't fit, it was the fact that the proper remover is no longer made. The local bike shop had one in their tool collection but wouldn't sell it. The kit is sufficient for those with newer bikes. I believe in the quality of the tools and would purchase it again.

👤The metal rod pierced the screwdriver handle after the first use. Do you think this will be from a $200 set? I was not.

👤I couldn't figure out how this wiring harness didn't help me.

👤I bought it to help my neighbor's kids rewire their quad and it shorted out the whole system and almost caught fire when we turned the key!

👤I used this to re-wire my yerfdog 3206 150cc gy6, although it states that it will only work with up to 125cc engines, I had no problems with it. There were only a couple of issues with this harness. The kill button does not have a back on it, this could cause you to be shocked if you grab it with out it on a handle bar and to ground out if it were to be close enough to the exposed metal of the handle bar, thus killing the engine. 2. I know the harness is only for a pit bike, but I would like to see a version that is extended or have separate extensions for purchase. It's a great deal.

👤The module was bad and not right for the rest of the assembly, I am thinking of retiring it and getting my money back, the module acts like there is no wiring in it.

👤I used this on a Honda atc185s (1981) and it works.

👤I thought I would need this harness, but found that the wiring was just as convenient, so I am going to keep this item. It's funny.

👤The pitster pro 125xjr has a wiring harness. After the first ride, the cdi decided to give up on me because it was only 15 minutes long.

👤I have a wire harness that works perfectly and it has connected to the other.

👤The harness is short and the connections are not in line with what I need.

👤The description says "EGR Head" but it is not. I would have ordered a valve cover if the description had been correct, but I didn't need to since it said it was EGR. The seller will have to make it right. I missed out on the family fun for the fourth because I didn't have a vale cover to put on my rebuilt top end.

👤The cylinder wouldn't go in the engine because it was big, I ordered it for the 57qmj engine which is on my engine and the rings were thinner, I would return it. I broke the thing because I was so angry, and I'm never buying from these people again.

👤The set came with everything needed. Sturdy enough for a small engine, but not the highest quality items. It's easy to put together, all parts fit.

👤This was installed on a trail master. Everything was perfect. It would be great if there were instructions, but you can find them on the internet. Hopefully the engine lasts.

👤I like doing heat cycles, but I take it easy until the engine breaks.

👤I paid for labor at the shop because of the bad quality I had to kits and will never buy again.

👤The cylinder is too large for the cam. The snap rings are too small for the cylinder. Very sad.

👤Excellent price, good quality.

👤I am trying to find out if my existing multi function switch that includes wiring for lights will plug in without damaging anything or if I should just run that system off. It would be nice if the multi function switch was used instead of the other switch. This is an ATV with a loncin engine. The product is great, everything works as it is supposed to.

👤I liked how easy it was to install the clean products.

👤It wasn't on the package that I needed it for. If I already paid for it, I don't know how to get it.

👤It wasn't rated for my buggy, but all the connections were wrong. I had to use wire from it to fix the harness I already had.

👤There were no instructions.

Brand: Cdh

👤It was installed on my YD 100. The stock muffler has a day and night difference.

👤Even though my tiny bike goes 7 or so miles an hour faster top end, it looks very small on the bike improvement chart because of the dimensions included with the picture.

👤I would recommend this over the stock one, it adds a lot of Torque and increased top speed. I have had it on my bike since august of 2021.

👤The performance was good but the pipe was loud and it blew exhaust on your pants or back rim, which is bad for breaking.

👤Nice fit requires modifications for the holder.

👤I thought it was smaller.

👤It makes my bike sound better. More power is highly recommended.

8. AUTOKAY Carburetor Coolster Chinese StrokeSUNL

Brand: Autokay

👤I ordered this to fix my ATV. I call these ATVs value ATVs. Run them for a while until your child is done with them. The factory parts are worth more than the value. My son has been riding a 125cc for three months. One day it started to get a bit crazy. The value stock car has less features than the replacement one. The air filter on the car was cheap and it made the car dirty inside. The one I ordered had a new air filter. The PZ20 is used for these ATVs. Measure your intake as the PZ20 and PZ22 are the same size. The PZ20 is a bit larger. The machine runs great again after I installed a new spark plug and improved air filter. The air filter does not have an aux hose off shoot. Some of the stock machines have an air filter that is similar to foam. The foam filters have an aux air line connection in the drive case and an extension hose off the carb. Some buyers think this won't work for them because this one doesn't. The stock air filter will separate from the extension. The extension part between the air filter and the carb should be used once separated. These are not the most expensive or feature rich, but at this price, you can just replace the darn thing whenever you need it.

👤I bought this for my kids fourwheeler and it worked for two days. It only ran for a few hours before flooding out after I couldn't get it to start while it was cold. It was pouring gas out when it couldn't stop the flooding on the second day. I tried to open the float with the screws stripped. Looking for a better car. I guess you get what you pay for. Disappointed for sure.

👤A good cheap car. Put one on a pit bike and another on a China bike. Don't spend more. These work well. Even if it only lasts a year or two. Theyre!$15! If they leak. The float bowl is most likely not it. You can reuse the same needle off your old car. They let gas pass through because they did not seat correctly. Don't just remove the old cap from your car and make it easier to install. The new compass and big needle are useful. I currently use 2 of them but have bought 4 over the years.

👤This is a 70cc coolster. It's put together better than stock because it has better access to the bowl and float. I usually needed the choke on and the idle where I wanted it. I put the orginal back on after throwing the old one in the cleaner. I'm sure one of the jets is incorrect, but don't get others to try. 50cc to 125cc all on the same jet? Unlikely. If you have the bigger 125cc it would work.

👤I had to put a bent piece of tubing for the air filter in place because I couldn't get the cable through because it was bent. It's cheap enough to just order a new one.

👤I wanted to receive what I saw in the ad. The only thing different was a light switch. I got a 70cc engine in a trade and wanted to use it. I took a chance on the stater wires because they caught my attention in the ad. I didn't know if my stater was 6 or 12 volts but the colors of the wires matched the ad. The 70cc engine is electric start only. I used a 12 volt battery. The electrical components with this harness are 12 volts. I think I got lucky because the engine runs and the battery charges. Thanks to BanchaoUS and Amazon.

👤The kit took me little over an hour to install, but I have to modify a few things to make it work on a tao-110cc. I didn't think this kit would work well.

👤It's all you need for a 50-125cc engine on either a pocket bike or a quad if you bought this for a build. I have other things to add in and modify it for so it seems like everything works well for me.

👤A good deal for what it is. It's worth the money. I was not using it for its intended use. I used it on my son's 160cc buggy, which needed to be completely rewired after I bought it. It's perfect for the buggy, it's charging the battery and good for starts.

👤It worked great. The set up was pretty much plug and play. A pit bike was rewired. The new harness I used had a white and yellow connection, but the extra yellow wire came out of the motor. There is a lot of information online to learn how to set it up. Thanks.

👤My daughter's harness was replaced well. The remote was cut off, but it didn't have the key. It works perfectly after being replaced with a harness. It takes a little wiring know how to do it. Not a direct fit but very close. Got it fast.

👤It works for a tao tao 110b. This harness does not include wiring for lights. My son is tearing to field up now that it's been installed.

👤The paperwork is terrible, go to YouTube.

👤If you use this one, make sure you use 2 grounds the main for battery and have a ground for spark.

👤I decided to go with the Nibbi 26mm after reading all the good reviews, so I ordered this to complete my system. No one measured it. I noticed it was small. I compared it to my accessory. It was a little bit smaller. It was confirmed when I threw my micrometer on it. I decided to take a chance on another one and port it out. 2mm is a big deal when I upgrade my car and it's a problem with the induction system.

👤Fitment is close. For the low cost, you get what you pay for. It's well enough. It does its job well. Close your eyes, cross your fingers, and pray for a good outcome as the gaskets are hit-or-miss.

👤Upgrading from pz20 to vm22 on a boom Vader has good intake. The bolts to the head should not have a wide one. It's in to the intake.

👤It fit just right.
