I’m quite surprised that your disappointed in the results going up to 26” tyres. As I mentioned, I run 28’s, although there’s a substantial difference I didn’t think it was all that bad, I find my 450 equally as powerful as my fathers 500 foreman which is bone stock.
Have you had this foreman a long time? Would it be worthwhile checking compression and adjusting valve lash? Just wondering if your down on power at all.
I do feel your pain though buddy, when I got my first 300 fourtrax I bought some aggressive mud tyres thinking they’d be awesome and I’d never get stuck. How wrong was I..!! It didn’t have the power to turn them in the peanut butter gloopy mud, ended up selling them and throwing tons of cash at it and eventually built myself a great mud bike.
