    ESR 265cc kit questions

    anybody have one or know somebody that does??? I was first considering the 310 kit but it would take balls to keep the stock swing arm, on the trails I ride on up here, forget about it..... Anyway I was looking into the 265cc fully ported kit (TRX 9), I think that would be best, for trail riding and for high speed
    Anybody know anything about this kit or better yet have first hand expereince???

    go with the 310(if you buy new), you will get bored of the power from a 265 quickly, I went from a 258 to 330, back to 258 and finally was happy with the 310pv I have now(it has way more power than any sane person can use, but I'm not exactly sane, so at times I'm, looking for more power). there is a lrd 270 pv on eaby right now, $800, its a real good deal and mine is lrd done cylinder and it rips, I'd imagine that a lrd 270 would be way faster than a any esr 265(I don't like esr's porting very much )

    I know but the 310 kit with stock swinger on the trails I ride on??? I get through crap that utilities struggle through, rocky, bouncy crap. Anyone who lives in New England will back me up on that. I just think the 310 kit isn't really practical....

    A 310 is very ridable with the stock swinger. Like Deathman said, you'll get bored with the 265 kit and want more power, especially if you're any kind of rider. If you set on the smaller cc's, take the stock jug and bore it to 269cc, have it ported and you still be ahead. One word of caution on this though.. don't take the bore all the way to the max or you won't have any overbores left.

    Blown 331, If you can afford to do it, buy that baby. The one deathman53 has is a pro-x cylinder. They rip, the 330 has a little more torque than the 310. The 310 will probly wind up a little quicker.
