How To Correctly Adjust A Motorized Bike Clutch

[@king49334]

i find that clutch shaft assembly wear out. the ball bearing inside it will wears out the shaft.

[@LAHover]

I have never had that issue, but it does make sense. Good call

[@doccpu7]

Doing a new install. no matter how you pull on the clutch lever even with a 2 foot bar it will not loosen the clutch. Can they freeze up? [e-mail]

This video is superb! I ended up throwing out an engine, due being unable to figure out why the clutch wasn't disengaging. If only I had watched this sooner... This is the ultimate guide to clutch problems, and prevention. Thanks so much!!

[@MotorizedChuck]

There is 1 item he doesn't talk about. That is the inner spring lock pin inside the shaft that also holds the spring. I replace that pin,(by disassembling the clutch lock nut and spring), I found this lock pin both bent and broken in cases. You can fix this by replacing it with a grade 8.8 bolt and grinding it down to size. Now you gain a stronger inner spring lock pin, it is a mm longer barely touching your spring. Set your preload tighter and safely now.

[@jaxknet]

Thank you for all of your content! I had never worked on any 2stroke anything, or owned a motorized bike. I slapped an engine kit onto a mountain bike that I've had for years, and it flies! It's thanks to you help and in depth explanations that I'm getting more comfortable with adjusting clutch, etc. Just had to say thanks again and keep up the wonderful content :)

[@markwatson1970]

Just adjusted my clutch incorrectly. This clarified things. Great job.

[@LAHover]

Hey sorry I'm late, I just saw you video, Is it still slipping?

[@markwatson1970]

@@LAHover yes, slips. I’m sure I overtightened the flower nut just to get some grip. New erasers, and tightened the inside(shaft?) spring , 1’ plus by rolling the bike backwards. I scuffed up the clutch plate a bit to increase grip, I put in a slightly longer clutch push pin that touches the ball bearing to compensate for the flower tightening. I noticed a lot of play on the clutch large sprocket. Could this cause my slipping? I’m stumped. I can get the bike going but it takes a bit of low speed peddling.

[@LAHover]

@@markwatson1970 Side to side play in the large bevel gear is a sing that the tiny friction plate bearing may be failing / falling out, but as far as I know it wont cause slipping. Once you get the bike started does the clutch still slip much during acceleration?

[@markwatson1970]

@@LAHover it accelerates fine and behaves once I get her going. It’s the initial grip to turn over the engine that seems to be lacking.

[@LAHover]

@@markwatson1970 I'm starting to think your motor may have great compression. Try these pads instead www.amazon.com/dp/B095HLBWFN/ref=cm_sw_r_cp_apa_glt_fabc_PX8M165D4VKPG5QHRV5R I have seen people make their own by cutting car brake pads as well... I'll be trying it in a near future video as well.

[@traehodges3796]

I used an Old drill bit as a bucking bar as I lost mine I just used the the same diameter drill bit as the bucking bar cut the drill bit off obviously and used the part that sets into the drill it seems to work fine and is holding up fine better then the stock one alot stronger material

[@williamshufflebottom-k3t]

You’re a really great teacher. I love your lessons. There so enjoyable to watch. Thanks very much for making them.

[@AutoCannonSaysHi]

Just bought a used bike and needed to know the details for adjusting my clutch. It's mostly good but at full power it likes to slip. Glad to figure out it's pretty darn easy to adjust, thanks for putting this all together!

I never do comments this is my first one ever... but this deserves it .great video wish more people did them like this... again thank you for going over everything and specific reasons why

[@donaldgtidwell2198]

Thank you for explaining things as you go, I'm new on these motorized bike, I bought one off a friend at work, he sold it cheap because he had it all apart in 2 boxes, I've never put anything like this together I almost told him I'd pay him more just to come get it, but I began to watch your video and a couple more others and in my amazement I put all together, so thanks again, if I had to take it somewhere to have it work on couldn't do it, your very understanding my friend.

[@CuddlyJon]

Thank you so much man. For a long time, it took me a while to start my bike up. I thought it was because the motor had to "warm up" or I wasn't giving enough choke or what not. Little did I know, my clutch had been slipping since the beginning. I needed to adjust my inner collar nut. Now, as soon as I let out the clutch, she springs up to life!

[@LAHover]

If you still have slipping issues check the video description, there is an advanced repair video link.

[@richardsaddress580]

13:30 Good info on the "neutral position" of the bucking bar and where to grease. Thank you, sir.

[@soggyridesmotorizedbicycle6258]

Thanks for being so thorough on the clutch assembly. It was always something that I shied away from. It was easier once I saw one taken completely apart. I appreciate your explanations too.

[@warlock.420]

Your troubleshooting and repair videos are the sht! So happy you take the time to explain what to do and why. Your videos are gold my friend!

[@MrJoeltrain]

I have burned up about 10 bucking bars. I finally found that WHITE LITHIUM GREASE works very well. I want everyone to know this as I have been stranded due to a melted bucking bar on more than one occasion.

[@MotorizedChuck]

That's funny as heck. Because I preach about greasing the ball bearing and the bucking bar, the case lever and the bevel gear

[@badbadbob1]

Very well thought out, This video should help with identifying what was not only wrong with the clutch but even better stop issues by setting it up correctly. Thanks

[@Everatti]

I rebuilt the entire clutch assembly on my motorized bike about 2 weeks ago. Really wish I could have seen this first 😂

[@Everatti]

Also, can you cover the internal clutch shaft, spring, etc. I feel like it plays a big role in the clutch feeling and adjustment, but always gets overlooked. Sometimes, the issue is beyond the bucking bar, flower nut, cable tension, etc.

That's a Really great video.Thank you.I use a magnet to pull the Bucking Bar and Ball Bearing together.1st time I wanted to re-grease I figured that out quick.LoL.When I installed my 2nd motor I removed the assembly that holds the cable end over the clutch shaft and squeezed in about 2 tablespoons of Gear Oil for that area.

[@keeganhache6667]

On my clutch cam for a quick fix I sanded it flat so it would engage again works well

[@JohnWaldron-cm7ce]

Great video! I so agree about the clutch lever cam assembly being assembled too tightly. Mine has very little "wiggle room" and I don't have any puller to disassemble it. I ordered another one that's disassembled, so hopefully I can assemble it with more cam shaft/bucking bar play-John in Texas

[@bernieolivera5632]

Your video is very good. My question is. The inner bearings on each side went bad. When I remove the clutch assembly some of the ball bearings fell out. The bearing races are pressed in. My question is simply how do you take these races out so I can put new ones in. Tried heating the bearings with a propane torch. Then I tried knocking them out with a hammer and chisel. Didn't work. Any ideas?

[@richiewheeler1810]

I appreciate your very detailed description of what each part is and how it works together with the whole system. This video has helped me greatly. Thank you

[@halethewhale]

I use heat shrinks as a cap on clutch cable it's handy, you can still get cable out without removing anything

[@rockytransaman8288]

I did like the video as it is very informative. Not sure if I'd fallow you on fastening the gas tank to the top frame bar technique. I guess that the little bolts were broken or stripped. If so, I'd have replaced the tank.

[@codelicious6590]

A couple of the replacement bucking bars I've gotten on Amazon have been too short, leaving me wondering what the heck I had done wrong. I found one that actually gave a measurement and sure enough, when compared to the previous ones I had gotten, it was a few MM longer!

[@DaleBladez]

2:07 I run a spring over the cable between the clutch lever and the cable tube. The excess cable I then tuck into the spring so it doesn’t stick out and poke me or fray.

[@donaldgtidwell2198]

Thanks!

[@Ozzieseth]

Also another reason your clutch might be slipping might be the small drive gear. How I fixed it was I got a bolt and put the head of the bolt against the bevel and drive gears to lock the motor up. Then I tightened up the bolt and that fixed my clutch issues

[@LAHover]

That gear should be keyed as well, but if the fix works for you that's great.

I've learned that if I take my new upgraded clutch pads and pass the outer edges on a grinder just to smooth the edges out they move towards the inner clutch disc better and bite on both sides better.

Interesting, thanks for the suggestion.

[@oimpastato]

Well done! Thank you. Have you ever find the need to adjust the inner spring on the clutch shaft? I know you can remove the cable holder, and place a sizable punch and move the rear wheel forward / backwards to help adjust.

My clutch arm has to be turned in WAY past neutral before it gets close to touching the bucking bar. Do any of these engines use two bucking bars? One smaller than the other? It may be a false memory but I thought when I first got this (PK 80) that there was a big bucking bar, a bearing and a smaller bucking bar but if it did, I lost the smaller one. My bike has less than 10 miles on it and the bucking bar is already very rounded over.
