ive been looking through everything and i see that a lot of you have beefed up you engines to go faster i want to just change belt pullys so i go faster but with lower rpms. ive a 2004 train pretty stock and noticed that when i pust it 75 thru 85 and hold it for a long time she gets hot 250+. temps here r in the 90s +here where im at. but when i toodle around temps r good between 150 and 200. so im thinking i can change the belt pullys and belt to get lower rpms at those speed it will clear up that problemi have push it beyond but never held it there long enough to see what happens. i was looking at a 34 trans pully and a 61 rear wheel. so ive come for opinions .
