Just a quick question for the more aggressive/racing setup.


when you square up the secondary with the drive clutch, does anyone allow for twist under heavy load.

I have read that when your alingment bar is touching the back of the secondary, there should be 1/16 gap at the front of the secondary.

this seems excessive, can anyone else tell me what the proper gap should be.

thanks

That is about what the spec on this is unless you have installed hard motor mounts or torque rods.

thanks for the post

Motor mounts were exactly the problem with my 98 xcr 600.

did a 1/4 mile last weekend - 95 on radar? opened up and saw nothing wrong. Next run, blew up a belt.

Got it all back in the garage - motor is twisted. mounts are crushed in front and torque arm is crocked.

What a job to re-align! almost need to dump your coolent and pull the motor! Re-shim the secondary, etc.

Anyhow - enough complaining.

I reset the motor but now I think the center distance is off.

Does any one know the center distance for this sled?

thanks for the earlier responce.

I believe the center - center distance for your sled is 12".
The 1/16" gap specified with the alignment tools is for sleds with over 500 miles on them because of the mounts becoming softer and allowing the engine to "settle" in this position. The only way I have found to correct this is to install mounts made of a harder rubber.
