I don't think you have a front end weight bias and dropping the rear 1 inch will not make a noticable difference. Racers run 18" rears with 20 and 21 inch front with no problem. The only thing you might notice is the slighty is slightly heavier at low speeds and more stable at high speeds due to the increased caster. But you are talking about 1-2 degrees, this is nothing. If you would tell me you dropped the back 5 inches, then you would have problems.

An easy fix if you are still worried about this is to buy a new chain or cut it to position your bearing housing so that bearing are at the bottom when you tighen everything up. This will probably give you back your height.

 

Good call on the axle carrier Rob, I'll try it out. I remember specifically placing it further up when I set up the chain, and bringing it down might make a difference. I am more enterested though in the caster, tell me more. I have +2+1 lonestars and they are fully adjustable. I tried to follow the instruction LS sent me but I don't have anything to measure the degree's of caster so I just set it up to turn well and fill stable and I just blamed the roughness on either the shocks or the swingarm.

Booger, looks like you decided to stick with the R. I think that's a good call. I have two of the newest 4-strokes now, but there's not a riding day that goes by that I don't recollect the good times on my old R. Yours is pretty sweet too. The optimum choice is to have both the R and a new one, but sometime you can't have everything.

 

I don't know how to set up the caster on lone star arms or how much the stock 250Rs have.

But the more caster you have, (meaning the further forward your bottom balljoint is in comparision to your top balljoint) the more stable it will be at high speeds.

The less caster you have, the easier (less effort) it will turn at slow speeds. This will cause the quad to get squirrly at high speeds though.

You want a good balance unless you are setting the quad up for a specific purpose.

E.G. less caster for MX to lessen arm pump and fatigue, more caster for hi speed drag racing to make the quad more stable.

I hope this helps.

 

Yeah, I got the whole stable and easy to steer concept an I have it where I like it. I just thought you where saying that the caster could make a difference in shock absorbtion.

No it will not help the shock absorbtion at all. I was a pair of triple rates up front set to my weight on +2 +1 arms and it rides like a dream. This is where my quad really shines when racing other machine down gravel roads.

You need to revalve your shocks.
