and to and thanks for joining the XT Supporters, check your inbox for a message from me with more instructions and links to the Service Manual download.

thank you does anybody live locally that would do the mods for me as i would only mess it up and have no tools i would happily pay for help ;/ im in manchester uk

co2 mod and tps mod i can do thanks so whats next so i purchase kevs fuel mod whats it for lol im confused? and what would be the next filter do i have to go up in stages ? o can i throw the best in? would i be better off buying the hyperpro fork kit or kevs suspension mod sorry for the confusion

Put simply, the XT motor runs lean to meet emission controls, this lean running is one of the reasons for the surging. Kev's fuel mod helps because it allows you to richen the mixture by simply turning a dial until the best air/fuel ratio is reached.

With a Kev mod fitted you can go to stage 3 straight away. Without, just stick with stage 1 filter and snorkel removed.

Up to you. Both will improve things. IMHO the Hyperpro springs would be the better solution, but more money/effort. Fork preload spacers (like Kev's) can be fitted easily in 10 minutes. All you have to do is remove the fork top nuts and insert them on top of the springs.

Ok thank you is the stage one just the standard filter?

Think my first purchase will be the fuel kev mod
Then filters etc afterwards will look into kevs spacers but may go for hyperpro as i want the best setup
