Im going to be doing drags next year up the ski hill and i was wondering about switching my motor. and wondering about what motors i could use the one i was really looking at was the old vmax 800 engine but how much work to do so if not i was going to maybe go with a srx motor. so give me some ideas i just want to get some p***ys (cats) this year. lol

im not sure how much work putting a 4 cylinder is in a sx chassie , a fella like 800 would know, but what i do know is to install a srx motor in a sx chassie you will need to do the following ;
1- change the bulkhead
2- different clutching -primary and secondary
3-cdi and wiring harness 98,99- different than 01 -02 dcs ?
4-air box
5- different gearing
6- stock srx pipes will not fit under your red cab
7- srx hood does not fit on your side panels (belly pan)
8- srx motor much heavier for uphill climbing ? (may want to ask fellas from out west )
9- larger rear heat exchanger
10- diffeernet jetting and possibly different needles
700 red head case and cylinder ported with bender pipes and some l/w parts rocks . when i had my 2000 from a dead stop it would take just about a mile for a t-cat or a xcr 800 to reel me in . Sorry for them race is over !!!!!!!!!!
I ported yamirider's cylinders this year and with his pipes he runs improved 700 and altough he did not win he is right there 2 and 3rds against srx and f7 , his sled is very respectable .
