Honda Pit Bike Manual Clutch Conversion || CRF70 / CRF50 / XR70 / XR50 / CT70 / Z50

If you really want to harness the power of your pit bike, converting the semi-automatic clutch to a manual clutch is one of the best mods you can make. Installing a manual clutch is not difficult and I am going to take you through the entire process step by step so you can feel confident that you will do the job right when you upgrade your pit bike.

[@jpwise5365]

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?

[@brian.d.mobley]

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.

[@CraigLaCourt]

hi Brian. Thank you for the helpful video. I just did the swap but after doing so I cannot shift into neutral. Do you have any pointers?

[@brian.d.mobley]

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.

[@CraigLaCourt]

@@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!

[@brian.d.mobley]

@@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.

[@CraigLaCourt]

@@brian.d.mobley that’s a great lead! Looks like I need part 22816-035-000. It’s a pin. I’ll see if I can find it somewhere in North America. 👍🏼

[@theaidenman]

is there a way to do this in reverse, i would like a semi auto for my sons honda dirtbike.

[@brian.d.mobley]

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!

Could a penny be used to hold the drive and the driven gears from moving without damaging the teeth?

[@brian.d.mobley]

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.

[@gvn-xk6eq]

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

[@brian.d.mobley]

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!!

[@gvn-xk6eq]

@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

[@daihuynh6820]

[@brian.d.mobley]

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!
