Some help with centrifugal clutch install

It might not work for you, but when I needed a little extra clearance on one crank on one build I solved it by putting a grinding wheel in the chuck of the drill and taking a little off the back of the crank (with a helper holding things steady on the other side).
 
Update: Didn't get any work done on the clutch itself, had lot's of other things to do today. When I get some time this week, maybe an hour tomorrow Ill be able to cut down those pins and check if I need those gaskets.
 
I cut down those 3 pins leaving just a tad sticking out, it still barely rub against the new clutch cover. Make sure you leave a little sticking out, then use 2 more gaskets for clearance. I'll keep you updated when I receive my gaskets and do the install.
 
So I was looking at the parts that came with my kit, and noticed all of the bolts are of different sizes. And what are they for exactly?

One of the bolts is bigger than the rest, and half of it is completely stripped. Im guessing this is on purpose? And in the centrifugal clutch, whats the threaded part for?

Oh ok gotcha. Finally on thursday I will have free time to work on the bike, and I'll be able to check fitting, and maybe make the notch in the clutch for the key. I still don't really get how thats all going to fit.

Question about the gear puller tool. When I screw it in, it gets to a point where I can't screw the large pieces in anymore by hand. Should I get a larger wrench and screw it in all the way until you can't see the threads anymore?
 
Should I use a wrench to hold the bigger pieces in place while screwing in the smaller piece, so it doesn't turn with it?
 
Ok. And screwing in the small piece should be hard right? Last time I tried to do it, there was lots of resistance, so I stopped because I was worried that I was doing something wrong.
 
No I am still waiting for my gasket to come before I start installing and cutting. Did you cut it yet? I'm sure it's not difficult, just cut the same size as the notch on the small gear.
 
Ok. I was able to get the gear off. Much easier than I thought it would be. I see now what the cut out is. In the shaft there is that half moon woodruff key sticking out. So, if I take the centrifugal clutch, and cut away about as much as there is in the standard gear, it should be good to go right?

Exactly, but don't make the new groove too deep. You don't want to allow the woodruff key to be able to move up and out of the notch in the crankshaft.
Also, you can make it as long as you want to, but making it full length of the clutch hub is creating more work for yourself than necessary.
When you get close to being finished with the groove, cut a little at a time and check the fitment frequently until you get a perfect fit. Sneak up to perfection rather than trying to do it all in one cutting session.
 
Hey guys. So today I installed it. First I grinded down the 3 clutch pins, and it doesn't rub, no need for extra gaskets.
However I am having a hard timing putting the actual CC on the shaft. I got it on there as far as it will go, I made the notch for the key and everything, and it's all good, but how do I get it to go the extra couple MM? Here is a pic of what it looks like.
I don't think the notch is the problem, it's as deep and as long as the standard gear. I think its that widening part at the end that I don't know how to overcome. Do i just hammer it on or something lol I have no idea. Or should I make a gasket and fit this cover on like this. I don't know. If I put like.. two or three washers in between the big cover and small cover it will be OK. But does that mean the CC isn't on all the way?

I took a chance and turned it on without the cover. It worked very well. And it was a blast to start from a standstill without pedaling. Besides, I can't really pedal, not enough clearance. That will be the next part of the install. Who needs pedals with this clutch anyways :P

So the clutch cover won't close all the way because it's hitting the clutch? I read somewhere on here that they cut the bolt about 2-3 mm so that the clutch will go in further. You also want to put another small lock washer on top of the washer that came with the clutch. Did you try bending the crank with a pipe? Glad to see that you got it running. My gasket came in today, I will work on it this weekend and report back.

I haven't tried bending it yet, for the way it works, I think that's going to be the last step. What do you mean cut the bolt? The bolt that goes into the crankshaft, cut that by 2 or 3 mm? That would help if that was how to fix it. Yeah, I'm not completely done yet, so tomorrow hopefully I can get it all fit right, and install the washers and lock washer.
