Well I was playing around drag racing on soft dirt and raced a 85cr exspert honda and 4x4 bombarida 650-700? i weigh 255 he weighs probley 180 but it was a damn automatic bombarida 4x4 and he got me thru 1st 2nd and 3rd and i say half way thru 4th im not sure about top end cause it was`nt that long of a drag. Only advantage i see is him hooking up better 4x4 and i could`nt keep from breaking some traction in first thru 2nd I was amazed to have him beat me lol also a 400 or 450 ex raced him and was neck to neck but the 4x4 won again. i raced this guy and got him once as he got me once but only because his dum butt got a good head start. Man is something wrong with my raptor are is them 4x4 auto fast as crap? A fed of you know that my quad was stolen from me for about 2 years and the engine has been into and etc and it probley got raged out and im sure it needs valve adjustments and carb cleaning adjustments. but my raptor rides hard and quick like it did before i cant tell a power differants but it has been 2 years since i rememberd the power so i cant say for sure. but right on to the new bombbardia with ford stickers on it that got my butt.
