Rich has the sarcasim font turned on in his post, but its not far from the truth. My first bike was an 81 MX 100 (an RT with metal tank) Back in those days I was in the 130 lb range, and the only way to make that bike wheelie on flat ground was to sit on the back wheel, flog the throttle and pop the clutch. I currently own a RT 100, my girlfireds bike, and she loves the little blue mini me to deth. The bike tracks great even in snoty mud and rocks, its tractor like first gear and motor power will wind up surprising hills and terrain. I keep wanting to get her someting a bit bigger with some more power, but every time she rides the bike she gets better and praises the thing to high heaven. We just rode Sunday. When I hinted she may be ready for another bike this year ohhhh she got mean I thell you! :debil: When I had my MX, I geared it down with the largest and smalles sprockets I could get (dont remember the #s) and was able to get it to loft the front wheel with a HARD yank of the bars and all the throttle it had in 3rd gear, 1st gear was more or less useless though. So, No the RT should not be able to wheelie. :laugh: It has low compression Ratio as you said, it has NO expansion chamber in the stock pipe so there is no real "power band" hit. I have searched the earth over looking for a pipe with a chamer for the bike, as far as I know, if you want one, youll have to fabricate it, and it wont be easy considering the shape of the area you have to work with. Its not like you could graft a YZ 80 pipe to the job. Let her ride and enjoy the bike, theres nothing wrong with it. And DONT be one of those boners that removes the oil injection system! There is noting wrong with that either if your not fouling plugs!
