ok well ive never heard of a 4 stroke bike ever needing a rebuild exept if its gone pop and ive been around bikes since i was 3 my dad was the truckdriver for peter stevens for 5 years and owned sychaul motorcycle transport i have also been raceing bikes for about 4 years but never had to do a rebuld and my motor has done well over 100 houres

 

 

another idea just use hyabusa throttlebodys and computer they will give the 4k what it needs+ the compter is fully programable

the injection could be a bit much but the hyabusa computers are programable to change flow volume
