xr200 bottom end in 200x?

[vartiak15]

ok if i put a xr200 bottom end what will i gain? also if i put an xr200 cam into my 200x will that make a difference?

[trikerider2oo7]

probably nothing...i would say it they are both 1:1

The cam is supposed to help top end alot. The bottom end you would gain a 6 speed instead of 5. The six speed would "close the gap between the gears and increase the spread between first and sixth, providing a gear for everything from tight trails to flat out screaming"(quote from an article from 3 and 4 wheel action).

can i just drop in an xr200 cam?

[TrikeKid]

the atc motor is derived from the XR so yeah

[smokinp]

a xr 200 carb will give you more power too

[vartiak15]

ya the carb will but i can get a brand new cam for 74 bucks (the stock one that is)]

.... won't the kicker be reversed on that XR's lowerend?.

[smokinp]

yes if you use the xr bottom end then the kick will be backwards but you can use the 200x gears to correct the problem.

[trikerider2oo7]

yea, that and you will need to use the left sidecase too

[smokinp]

wouldn't it be easier to buy a complete xr 200 engine and put it in?

[trikerider2oo7]

yes...but it will be cheaper to just get the bottom end
