questions on shortening forks
« on: January 18, 2015, 12:03:06 AM »
I getting ready to shorten my forks internal. My question is when making the spacers.  How long do I make them to keep a 2'' ground clearance?

having 2" ground clearance is going to be up to your specific bike setup.

Measure the bike now, and measure how much fork you have sticking out.
Put a front end strap on the bike and pull the front down until you get the ground clearance you want. Measure how much fork you have sticking out again.

The amount of spacer that you remoce and put back on teh other side is the amount that the fork will shrink, in this case, shoot for the difference in the two form measurements.
Any day on a motorcycle like this that ends just needing parts and labor is a good day.

K, thanks. Great information,but unfortunately I have already disassembled the front end. I'm getting ready to tear down the forks. I will be guessing at this. I'm going to make spacers in 3 sets with o.a.l. being 1.75, 2.00 & 2.25. I'm leaning towards the 2.00 length. Hopefully, it isn't too much.
