XJ650 uppers with XJ750 lowers?

Hello,

I live in an area that has very bumpy roads, I am currently experimenting with 20w oil in the forks, but I have the oppurtunity to get some 750 forks with the anti-dive, will my 650 stanchions, uppers, fit into the 750 lowers? Both have the same diameter stanchions too.

it would seem to solve quite a few of my probs!

cheers

 

I don't know the answer to your specific question, but I can tell you this:

If you have any problem other than excessive diving on stops an anti-dive won't solve it.

Changing oil only changes damping, it does nothing if your problem is caused by the springs.

What problems are you having?

 

The roads where I live and ride are horrible! deep long ruts that when you hit them at 100kmph plus, virtually bottoms out the whole bike, as well as short sharp jolts from holes, as well as those raised bumps from tree roots.

in fact, I often ride on dirt roads because they are in better condition.
Overall I am sick of getting sore kidneys whenever I ride. Front fork seals are new, rear shocks are new.

From what I have read, anti-dive might go a long way in easing many of the sharp and deep local road's bumps.

 

Really- dirt roads are better !
If you added 1 inch spacers and reduced your fork oil viscosity, you would gain travel and softness. If you could find Turbo air shocks, or longer travel rear shocks, same thing, softer ride.
