Yet another question on shims, springs, etc..

It's time for new tires, and I think I'll go from 25" to 26", and doing Bearclaw HTRs. I imagine I could do just fine with a stock CVT setup, but I wouldn't mind getting just a bit more low-end, even if it costs me a bit of top-end speed. If my top-end went from 60 to 50, I'd probably never notice. I'm not, however, looking to put a lot of money or modding into it. I've read a few threads here and other places, but I'm not entirely sure I'm grasping things.

In order to get just a bit more low end, I'm thinking of adding a 0.5 or 1mm shim, and calling it a day. Is there anything wrong with just doing that, and leaving the springs/wet clutch alone?

Or, if I wanted just a bit more responsiveness in down-shifting, which spring color would be a mild/moderate step up from stock?

I wouldn't bother with 0.5 shim, but some mite say otherwise. I'd start with a 1mm shim and ride with that for awhile. If you feel the need, now or later, most upgrade to the Epi purple spring.

You probably not notice any torque loss with that tire.
On the same note you probably wouldn't notice any gain with the .5
Adding 1.25 or 1.5mm shim will be more noticeable.

You would notice the difference with or without any of the above by adding the purple spring.

I would ride it stock after the tires to see how you like it first. My buddy moved up from 25s to 28s and I put a 1.5 shim and purple spring in it for him the same day we installed the tires. He called me after his first ride and said the shim and spring was waste of money because he felt no difference. He didn't know how much power he lost because he never felt it with the bigger tires before the clutch work.

I put 26 outlaw mts on my o7 450 and relay didn't notice much lose in power. Only mod I've done is cut the diaphragm spring down to let it open up faster. Ok just read 28's I recon eye sites goin too.
