what engine mods should i get to improve both my low end and my top end without sacrificing one for the other,if worst comes to worst i would rather sacrifice top end for bottom end. I have most of my other mods figured out. I am not going to bore it out cause IMO engines get unreliable when they get bored. here is all the non engine mods i am gonna get 1.Suspsension (front and rear) re done by independant suspension and a paddle tire with a rim in the rear 2. get yoshimura trs pipe and jet kit and twin air foam filter 3. short levers so i can use only 2 fingers 4.belly plate 5. fork guards 6. renthal fatty barss and tag metals risers 7. steering stabelizer 8.acrebis handguards 9.IMS pro series pegs 10. yz450 fenders (just the fron and rear fenders not the radiator shrouds and all that junk) 11. did x ring chan and renthal stock size sprockets are these good mods? just to start with? ( i really dont know cause i have been into quads for years and now i am switching to bikes and i dont know whats good for bikes and whats not) anything else i should get before i start modding the engine???
