Loking to replace the facotry tires on an older Kodiak, this one is a "semi auto" with high and low.

I cant make up my mind 25" at or 26 XT I know the differance and price doesnt matter to much. Mostly trail riding and I would rather go around mud than threw it ! I guess Im getting older!

The bike is modified with a cam, milled head, two steps bigger in the jets and aftermarket needel, K&N etc.. It has a jet hot coated header and IDS2 slip on so its not hurting for power.

Would the 26" be hard on the clutch?
