I can't seem to get the Clutch to disengadge

[Jvan]

Hello,
I just got everything ready to go for my first ride and I can not get the clutch to work. When I'm pulling the hand lever it is pulling the arm but it will not allow me to move the pedals...? Is there some type of adjustments that you are supposed to make on a brand new engine? This is on a 80cc 2 stroke motor by the way. Ant help would really be appreciated, as I am really interested in taking my MB for a ride. Thanks!

Sometime first time you try to may be a bit hard.
Might try removing the cable from arm and use a lever. I use a short piece of pipe and GENTLY push it in. Make sure pipe is butted up aginst where it connects at cover or it will break.
There may be a pop like feeling and sound. Move in and out a time or 2 put cable on and adjust.
Might look for the post on making it easier to work with a small adjustment.

Thanks biken stins! I will give this a shot. Being gentle isn't one of my strong suits but I'll give it a try. I also ran into a guy that fixes bikes at a local bike shop and he has a motorized bike and I am trying to get him over to take a look as well. I know this is something that anyone who has built a MB before will probably look at and get it fixed in minutes. Having this web-site as a braintrust of collective trial and error and succesess is a beutiful thing. I only hope that my knowledge base grows enough so that I can offer some help to people in the future. Thanks again!

Hi Jvan, I had this problem. Here is one of my first threads which helped me.

Thanks for the reply! Just need a little more info

Hey Graucho,
Thanks again! This does sound like my problem and that maybe just getting it started could get everything into place. The question that I have and keep in mind very new at this is how do I get it started? Right now as it is I can't really pedal the bike because the clutch wont engadge. I took the spark plug out to release the compression and just lifted the back tire and gave the pedal a push and it made sounds like the engine was going to fire up. Although I know that isn't possible with the spark plug out. If you could give me a little more info on this it may be the trick I need. It is mid-to high 60's today in WI. so I have the itch to as mountainman says "ride that thing".
I'm thinking that after reading the thread that you turned me on to that it could just be that it was really cold when I got the kit so there could be some cold coagulated grease in there that is binding it up. If you could please shoot me a note when ever you have a chance I would really appreciate it.

Try routing your clutch cable as free as possible I have mine straight across the front of the forks it won't go anywhere. Then instead of the way most guys tie it to the frame let it arc freestyle and it will be easier to pull in and a lot smoother it will stick out there a bit but it won't bind like when it's tied down. On my motorcycle I have it that way and the MB, the cable lasts forever because your not binding it with turns. Use the throttle cable to keep it up in the front or a brake cable, headlight bracket or anything out in front to support it a little.

The clutch friction plate is stuck

take the chain off

Take a flat screw driver and carefully pry on the teeth
of the front 10 tooth sprocket to turn it

Use the boss on the bottom as a pivot point for
your screw driver

The sprocket will break free

I had to do this on all the Raw motors I sold as their
clutch pads are very uneven and they came locked up

Grubee motors spin freely right out of the box and their
clutch pad are even and of a better material
Grubee's are also test run in the factory

take the cover off the clutch (right) side and you
will see the presure plate move out when you pull
the clutch
Also grease between the gears with thick grease
Don't use too much or too thin a grease as it will get
on your dry clutch pads

If that doesn't work you will need to adjust the clutch

I'm thinking that after reading the thread that you turned me on to that it could just be that it was really cold when I got the kit so there could be some cold coagulated grease in there that is binding it up.

There is no grease binding it up
as it is a dry friction plate clutch
Take the 5 screws out and look on the right side

This one worked and Also Graucho's as well

I used a little piece of pipe and was able to push it in just enough to disengage the clutch and wired it up again and it was working. Gased it up and got it ready to go and realized that the fender was slightly rubbing against the chain so back to the shop for fender modification. Then out for a ride. Started pedaling down the street and it started up right away after releasing the clutch lever and a little bit of throttle, It sped right up but wanted to make sure that the coaster brakes work after having a big issue with the hub earlier and when I pressed in the clutch lever to begin decelerating the Engine started reving up quite a bit so I hit the kill switch. and looked it over adjusted the choke and tried it again and the same thing happened and kept happening. Then my chain popped off and I'm not sure why because it was really good and tight. Once I got the bike started and took it for my 30 second ride the clutch was much easier to disengadge. Well back to the shop to put the chain back on and figure out the reving up issue. Just wanted to enter in an update and thank everyone for their sage advise. Thank You!!!

Chain might be too tight, you do need a little play. Also check alignment from back of motor to sprocket on wheel it should not be at an angle. It should run straight back
