Like everyone else had said, Bravo! Keep the videos coming. You have truly been a big help to many of us out here just learning about these cool bikes.
I really enjoyed this video. I'm getting ready to restore a XR50 clone for my grandson, and I'm enjoying all these instructional videos. I also just bought a 1974 XL70 that I will be restoring.
First off great job on all your videos!! Youve helped a ton...Second, have you any idea why my clone 70cc semi auto just shifts in circles? 4 down but if in 4th you can hit down again into 1st right over neutral, about fliped over the bars at speed, no fun. Took off clutch and took a good look at shift spindle, star, and the lever riding it, nothing obviously wrong...
Hi Nicole: I got the kit from TBoltUSA.com. They frequently sell out of the kit, but look them up on the web to see the current status. tboltusa.com/store/tbparts-manual-clutch-kit-br-z50-crf5070-xr5070-pit-bikes-p-273.html
Hi Duane! So glad it helped you! Thank you for watching! I am doing a manual clutch conversion on a KLX110 right now, so look for that video to be out soon!
question for you sir, I'm getting ready to restore a TRX 70 but wanting to put a 190 or 212 E Start engine on it. However, they all come via Manual clutchs and I want to convert them to semi automatic. is that a service you can provide?
HI Wise’s! I don’t work on “customer” bikes. It just takes the joy out of work. But, Im not familiar with the 190 or the 212. Its seems that converting to a semi auto should be pretty straight forward. Ill bet you could find the parts needed on eBay. In fact, if you want to sell the 4 speed, I might be interested in buying it.
Hey Lars! Well, BE CAREFUL first of all. Make sure all the bolts holding the cover are off. Makes sure the kickstart is off. Oil drained too, obviously! The most common reason it doesnt want to come off is because its stuck around the shift shaft. Try wedging razor blades between the cover and the cases on the opposite side of the cover from the shift lever. Work the blade around. That SHOULD break the seal of the gasket. Take your time and dont force it!
@@nicolevargas5588 I’m sorry but I don’t really understand your question. I’ve had several people read your comments and none understand what you are asking. I can tell you that I have not worked on a Lifan engine and I don’t know about the size of Lifan components.
Oh man…! No bueno. The most common shifting problems come from the “star” on the selector drum not being righted to spec. BUT, there are other reasons that may cause this. The spring loaded arm that “hooks” the pins on that drum get bent on occasion which can cause this neutral select issue. Sometimes the same mechanism can hit a casting protrusion near where the shaft onto which the shift lever mounts. The fix for that is a bit of grinding on the shifter shaft mechanism where it hits this casting. There are so many things that it could be.
@@brian.d.mobley thank you so much for replying. I realize it’s not your product but do you happen to know what bike they source the kit from? I feel like there should have been either a set screw or set pin that holds the lever arm in place where it enters the side cover (I realize it’s not what we were already talking about). The kit we got didn’t have one so ther is no way that this arm stays in place and keeps working out the front of the cover. I contacted TBolt but they only referenced the install directions (which I had already used along with your excellent video). If I know what it’s sourced from I can try to find the exploded fiche and verify if there should be a pin or set screw. Thanks again!
@@CraigLaCourt NO problem at all! Glad to (try) to help. Honestly, Im not sure of the origin of the manual clutch conversions that TBoltUSA sells. However, this type of manual clutch is common on several bikes such as a CT70H model. BTW, the service manuals out in the ether on CT's are horrible! I dont recall any pin that you reference being a part of the installation. If you need good exploded views, try CSMNL.com. They have excellent fiche for these bikes.
I heard once this is installed, you can still use the bike as a semi automatic or atleast it won’t stall out when at a stop without the clutch pulled in, is that true?
With doing this, can you then swap out the stock handle bars for say, protaper and put a clutch lever on them? Asking for a crf50f I’ve seen mods done to them where people have a clutch installed, I was wondering if you knew anything about that?
Hi I'm having a problem when my clutch came loose when I put it back on it spins it's self back of within minutes when I torque it down will stay on but it won't engage
Hi GVN19: There can be a number of reasons why this could happen. Missing parts is the most likely. The clutch on these motors is restrained from tuning by the interference tab of the locking washer. If that washer is installed correctly, it’s virtually impossible for the clutch nut to loosen. Beyond that, I really have to have the motor in front of me to evaluate it properly. I’ve gotten away from diagnosing mechanical problems over the Internet as so many variables can be causal. Consult the service manual and start over. You can figure it out!!
@Brian D. Mobley cheers for the reply mate the locken washer with the tab on us bent so I'm guessing it's that I've got a new clutch coming tomorrow so I'm going to try that I've only got a torque wrench with a minimum of 60 NM 45ft lbs so il just tighten it half way but my guess is bent tabs on the locken washer
Of course! Provided you are using this type of motor. Honda makes all the parts and they are very easy to find on eBay. The cheapest and easiest way would probably be to buy a complete motor on eBay and just swap the necessary parts. This motor has been around for decades and has been used on countless bikes. You won’t have any trouble finding the parts you need! Thanks for the comment and for watching!
ay man will this work on my 110cc quad wich has a centrifigual clutch and i really want a manual(or if i change te engine to a 125cc with centrifigual clutch)
Sure. Its less simple, but it can be done. If you are on Facebook, look up Maximus Payne. He knows EVERYTHING about doing that sort of conversion with OEM parts.
@@brian.d.mobley Thank you for the quick response, I just need to know the names of the necessary parts and I will buy them as spare parts for manual cluch!!!
@@sjivanov5564 look up Maximus. He knows all that stuff. Honda ATVs came with 4 speeds and most people who do what you propose use components from those 3 wheeled vehicles.
Hi Jim. Absolutely. Those gears are hard. This interference technique is common on most other dirt bikes and Honda even sells a part specific to this purpose.
@@jimmadonna1436 The service manual for the motor in the video recommends the clutch joker tool. But, the manual for my CR250 uses the interference fit tool. It’s much easier to use a flanged nut (or something soft like your penny) rather than buy that bulky tool.
@@jesusmaryandjoseph6 I guess I misunderstood. I’m not familiar with this motor being configured when there is no foot actuated shifting (semi auto). I am not aware of a bike using this motor that is fully automatic or constant velocity.
@@brian.d.mobley yeah most atvs and some dirtbikes from China have twist (press) and go throttles here in the US, with no shifting at all, which is stupid
@@jesusmaryandjoseph6 Well, I learned something new! Im frankly just no sure about converting from such a fully automatic transmission to manual. I wish I could be of more help.
@@dirtbikedad4107 Glad to read that! Sorry you had trouble. If you aren’t going to use the crank again, you can use an impact driver to break that nut loose.

I just got into mini bikes and this guy is just making my love for these grow and grow, your a mad bloke love the videos keep it up man👍
Thanks so much for the kind words!
Great vid i just bought my manual clutch assembly and i learn about how to install it thanks to you
Thats great Matthew! Its a nice upgrade to have. Thanks for watching.
These are really well done videos. About to start the rebuild on my CRF50 and these are great refreshers.
Thanks Andrew. I’ve got a new one coming soon. Hope you find it interesting! Thanks for watching!
well done bro, your channel is absolutely the best . I rebuild many things with your awesome videos! keep it up.
Thanks Majid! I have some good new vids coming so keep watching!
That little spring pop out on mine so thank for showing that but as I could not figure out where it went. 😂
Ha! Yeah, there are a lot of parts in there! Thanks for watching!
You are fantastic. can't wait to see how this turn ! You have a nice garage man!

Awesome vid and edits and filming and shop and bike
Thanks Conner! You would not believe how much work goes into all of stuff! Thanks for watching!
When I do it the other way around: do I have to replace the gear shift arm or are they the same?
Great video .Is it possible to change my 125cc manually shift to automatic without changing the transmission out ?
Honestly, I’m not sure. If there is a conversion kit out there it could be done possibly.
Thanks for good instructions ...❤
Sure! Glad it helped!
Thanks Great Video ! I just finished , I have a small O-Ring left over and a Seal.
I'm Guessing the Seal is for the shifter side??
Oh man….. It’s hard to say, but go over your service manual carefully and make sure you didn’t miss something!!!
VERY GOOD JOB !!
Thanks Vince! Hope you guys can use it for a little more clarity for those using your outstanding tech database!
Hi can you tell me wile converting auto clutch to manul clutch, have you used same Sami automatic clutch or a new clutch.
Do you have a video of the lever/master/slave install?
Because this motor powers such a wide variety of bikes, it’s not practical to cover all the variations of the lever install. Sorry.
I am watching to learn
That’s a good reason! Hope the video helps.

If we doing this on a 140 motor or bigger than the specified 108cc would it be wise to rebuild the basket with he plates? This video answered 90%
Hey Terpy. Yeah, this video is not really about rebuilding a clutch, but if your clutch pack is out of spec, I’d replace it.
I have a piranha 140 I’m trying to do this with but kit says it’s for up to 108cc. And I tried to email tbolt but got nowhere.
