630 to 530 chain and sprocket conversion.

Sprocket Stuck

To loosen that nut, before you cut the chain lean over the bike with your right foot on the brake and use a socket and breaker bar to turn it loose. I find it always works.

I found some pics from my time in New Mexico. Bill was holding the tire iron while I turned the breaker bar. He had "a go" at it while I held the tire iron and between the both of us twisting the breaker bar, it bent!



Bill let me have his old 630 chain...which was in WAY better shape than mine!

When we used to race Production Class, no mods other than tires,gearing and shocks were allowed.I switched to a 530 from the 630 and gained 6mph on top end.They thought I was cheating. I just got a set up from Z1,17/50 set up. I may return it for a 52. Stock gearing is good for about 130? With no fairing,its hard to go that fast or find some where to do it.I would rather get there quicker. Good prices fro Z1.There chain is a little heavy,but it is also almost $40-$50 less than the name brand ones. Vortex has a 530 set up.They use an aluminum carrier with a steel "tooth" area.Light,but tougher than aluminum.

Hi,
For those who have problems removing the front sprocket nut I found that using a mallet between the sprocket teeths and the frame to block the sprocket rotation works better than using brakes (no torque will be absorbed by the chain). With a pneumatic torque wrench it just came off very easily once I used this method.

BTW, I have a question, did someone had any problems with a 530 chain? I bought a 530 kit 14-43 and the sprockets are much smaller than stock, my fear is that the chain may touch the swing arm when it get a bit looser.
