110 and 90 cam

[83Atc250R]

Is a 110 cam bigger than a 90 cam? Will a 110 cam bolt into a 90 motor? Will it add performance?

it will fit, as everything on those two motors where preety much identical, and some of the models of 110's where just bored out 90's from the factory. it will give you alittle more performance, but not a whole lot, as it is only for a 20cc more machine, you will have to readjust your valves though, and timing might be alittle hard to get right, i know it was when i put my wild cam into my 90, wich is now bored to 122, has a cobra straight pipe, k&n filter, and a carb off of a xr 125, has 1 tooth taller in front, and 4 teeth smaller in the rear. and i have 2 more 90 motor for my parts for it, and have done preety much everything to it besides tear the casses apart, so if you have ne more? i hope i can help you out.

Ok first how much power increase did you get with all your mods? Was it worth it? What size over is the piston .060? Does it have heating up problems being bored that much?

i dotn know real numbers on how much power it gained, i know it is alot faster and gets going alot quicker than my friends 90, but he is also 200lbs and im 135. it will pick the front end up though in 3rd gear high with out dropping it into gear, and very little body persausion. i also dont know what the bore is now, i took it to a shop and said i want this bored out to just under a 125, without changin any thing else. ummm, im not really sure if it was worth it or not, because at the time i was more into motorcycles and wanted a fast trike for ice racing, which i never did with that any way becuase by the time it was done the season was over and i got a bigger bike that summer, so i lost interest. it doesnt have any problems with over heating as far as i know, as i dont ride it very much any more. i did take it out today just to make sure it still ran, and for the size of it, it has plenty of power.
