This site and OldMiniBikes Warehouse have been helpful to me in my efforts to learn more about small engines through hands-on working with them. I have a 6.5 hp clone in my Baja Warrior and with the gov removed, it has been fun! It is fun in my opinion to work on engine mods in a toy like a mini-bike as opposed to an engine in a lawnmower or snowblower since I don't have to worry about not having something I need if I mess up! As indicated on a mini-Tach, the no load rpm is around 6000 and under load at max speed on flat ground it is around 5000. I am satisfied so far with the top speed since the field/backyard where I usually ride really can't handle much high top speed...
The only thing that has bothered me a little bit is.... how long it takes to get to top speed! i.e. acceleration!
What are some mods (not too expensive) that I can do to improve the bike's acceleration?
Right now, it idles around 1700 rpm and when I go to almost wide-open throttle it seems to hesitate and bog down for a second or 2 before it accelerates hard... Some of this may be due to the fact that is has a centrifugal clutch. but the specs say the clutch should be fully engaged at 1800 and that rpm is easily obtained just by blipping the throttle...
