big bore ?

[2004400exrider]

i was wondering if i got the wiseco 440ex big bore kit and all i ride is like trails and sometimes mx. but mostley just wide open trails.would this be a good idea and if it is does it take away alot of engine life because i dont really want that. also what exhaust would i get for a 440.

id say its worth it. you motor will last long as long as you take care of it. oil change every 2-3 hard rides. changing your oil filter and good maintence. i love mine and its lasted a long time. i would get sparks x-6 with it as well. you'll be holding on for life if you never rode one. but its great power and speed improvement
