allmotor Posted March 14, 2013 Author Share Posted March 14, 2013 hi fellows blackhat is almost right, also the smaller rear sprocket, the stock exhaust back yz 80 muffler air cleaner no lid or snorkel needle raised. when i took it to the track last wasnt running properly picked up 6 tenths & 10 mph thats a lot of horse power with the small sprocket its hard to 60 foot , with the bigger sprocket ive had 1.895 60 & 17.6 with the small 1 best 2.31. u do the sums easy run 16s, Link to comment Share on other sites More sharing options...
dt502001 Posted March 14, 2013 Share Posted March 14, 2013 Hmm sounds like a perfect set up to run in ET,drive it out of the hole like a sunday cruise and run consistant low/mid 17.00's thats how trophys are won. No need to sand bag it. had a girl at our local D/S ooo 14yrs ago and she won the ET series on a kaw 440 never did a burn out,never tried to launch,just deep stage the bike and cut 500's and drive to the other end. I bet she never went .02 different and won more races on her R/T. Be neat to see a 175 win a ET series against 1300's,pro bikes with studder boxes,shift lights,air shifters ect that would piss off a few guys. Fair to assume that you have picked up at least 3- 5 hp to be able to gain 1/2 second and 10mph,pretty cool for just exhaust and intake work. You haven't shaved the head or anything else? Like stuff the crank area ,altered the port timming,bigger carb,porting? I would be inclined to clean up the stock porting( the stock casting is poorly done) not mod it just make it right. And add a ram air intake for track use. As these dt'skeep poping up more and more you might want to see if there is a intrest in your pipe design and make a few,guy's could keep thier stock pipe for shows and from rotting and gain a few hp,or in the case of no pipe left to work with an alternative. Any way I take it your going back to the larger rear sprocket and shooting for the 16's lets us know how it goes Link to comment Share on other sites More sharing options...
