I measured the engine bolt when I took it out, 4''. Bought a 5/16'' 4-1/2'' inch steel replacement today. It should do the trick. I bought a lock nut and 4 steel washers as well. Not sure about the swing arm bolt. I suppose when I replace the engine bolt I could try the swing arm but I don't have a garage or bike lift. I've also had a problem with my chain coming loose. I've tightened it 2 times already and I don't ride it that much. I'm not sure what to do about it.

Went with a 4-1/2'' bolt and it worked out nicely. Vibration seems to be much better with the new bolt! I only used 3 washers cause I couldn't get it to work with all 4. Didn't get to the swing arm bolt, sorry..

why did you take the pegs off for this? i did the bolts on mine and there was no need to remove the pegs you could of cut the 5" bolt also to make fit a little better and still use the washers like you did.

It was a pain to get to with the pegs on. I have limited tools and no lift or stand. I only removed them from the one side. Why would I buy a new bolt and cut it when I could buy one the right size? Sorry for being a noob.

I also didn't remove the chain, just loosened it..

No worries at all man, I am truly a noob. Only reason I did that way is because a youtuber (miamiscooterclub) did a video. I just tried doing what he did.

Took one of the bolts from my original sprocket and installed it onto the new one, the new one was stripped and the sprocket felt real loose. Hoping that fixed the chain issue.

Another problem I've had with vibrations on the Vader. The break light. Since I've installed the fender eliminator kit it's just been floating and vibrating like crazy.

I'm looking for suggestions as to how I could fix that..
Thanks in advance!!

Skin Mechanic also has a good write up on his engine bolt replacement. It should be the same for Vaders as I'm pretty sure they're all the same when it comes down to it. I will go ahead and order some replacement bolts too since this seems to be too common.

Not sure about the swing arm, but will look into it.

It is surprising that your chain is loosening up frequently. The main nut on your rear wheel should prevent that from happening right? Between that and the chain adjustment nuts, I don't know what else can contribute to that.

I wonder if the vibration was causing the nuts to loosen up. Not sure..I know I need a new bolt for the front sprocket, it won't completely tighten. Going to fix that later today. Might be the cause of the chain loosening up.
