Got My Hands Full....TRX250R VS LTR450

[ameier5051]

Here's the deal. I have always had the fastest out of all my friends. Well, one finally decided he needed another sport quad and bought an 08 Limited LTR450. I'm currently working on an 88 TRX with a Paul Turner worked motor and have a stocker 700 Raptor.

I don't know how the 700 Raptor is going to run with the 450 in a drag....what do you guys think the comparison of the 250 to 450 is going to be? The motor runs right now I just have to finish putting all the chassis together.

I would have to assume he will beat me top end but how long do you think the short drag will be?

I might be working on a project only to sell it in the long run and work the 700 over haha.

It will have to have at least a cherry bomb for a close race at all with a good running R. With a good pipe, fuel tuner, intake, and rider the LTR runs pretty well. Friends was making around 50+rwhp with those mods.

All depends on how well your r runs. The 700 will probably lose in a short race with a 450. Sell that raptor, buy a 310 or 330 esr cylinder and mop the floor with all those 4 pokes lol.

i would take da raptor off your hands if everything wasnt going wrong with my kx

ive found that a stock jug/ported 250 will be a close race with a mostly stock 450, as 265r is close too, but once u go 310 and beyond its all the Rs....of course there is exceptions to every rule but this is what i have found over time. My 265 was dead even with a piped, filtered 06 yfz450...and the 310s and 330s would walk past any 450

so i learned my lesson and if your gonna do up a 250r, build a nice 310 pv or 330 pv and youll never look back or have any doubts

i beat 450s wit my 89 250r all it has is a cr style piston k&n filter a pipe trackside that no one has heard of .170 comp advanced timing and beat 450s wit cam vavles port &polish piston full exhaust and correct jetting k&n filter and sure is fun to look back and see them in my dust

[fulltiltrider]

What kind of port work do you have. 170 compression is kinda low for a highly tuned r. I have a friend with a lt450, with all the fixin's, and it is a fast machine. He would pull my r everytime with my highly ported stock cylinder, and you see the mods in my sig. You must either be a good rider, or those are stock 450's.

If all you are worried about is speed, then get a worked banshee.

i put my own port job on it i dont like to high of comp bad on motor i run half&half wit castor 927 shes fast but my exshaust is crap it uses stock jetts for the years 86 to 89 i dont think im a good rider but i now how to run a fast machine and the 450s werent stock i know forsure
