if running 26 fury and trying 26 and 27 trophy plus..would engine height normally be same, higher, or lower..fury works pretty good but I just cant get the numbers that lots of people on this board are claiming..77 is best speed I have ever reached!! ran 26 trophy yesterday at same height as fury..more rpm but slower speed..5950 rpm/74 mph. weather was no fun so didnt stay out there messing with adjustments..thanks for any input.
