Im in the process of putting my extended swingarm on the bike and figured that I might as well get the shock set up for the extra length and my weight. I have called a few of the shops and I am getting different info. Im planning on running the bike 5" over stock and Im right around 240lbs suited. Some say that I just need to revalve the shock and that the stock spring is enough. And others are telling me that I need to run a stiffer spring plus the stiffer valving. I would imagine that after adding 5 inches of length and my fat ass on it I would need a stiffer than stock spring, but then again what do i know:grind: So for those that are running an extended arm and weigh over 200 suited what did you do? and what kind of 60's are you pulling? Im hoping that with the added length and shock ill be able to pull some high 1.3x 60's I figure the stiffer spring will also help keep the tire off the tail light. Im trying to get the bike as long and low as possible without having to change the stock tail.
help with shock spring rate

Be patient, we have several sponsors that can hook you up.
Don't have the #'s for the spring or the valving that you need...but yes you are gonna have to do the valving and the right spring to get those times you are shooting for. Even if you did not do the stretch the right shock will definitely help...PM 'Goldenchild'...he is a drag racer and a board sponsor...he can hook you up (pun intended)

First off, if you can post a picture of your bike from the side (upright) without you on it and one with you seated on the bike. Unless you can measure sag yourself. Your swingarm should be as straight-parallel to the ground as possible for starters. There are at least 25 members on this site with our re-sprung and revalved (shock dyno) tuned shocks the reviews have been outstanding as like everything else we do.
Once you extend the bike beyond the OEM length it takes more of a spring to keep the chassis up (think of the wheel barrel effect) then add a heavier rider, now that OEM spring is reaching its limit...then throw in hard launching and all is lost from their.
There is a specific formula for length, height, weight, purpose and power. A spring will help but to get 1.30's 60' you need a perfect set-up and perfect clutch hand and good rubber. A revalved and resprung shock is your best bet. This stuff is not rocket science but tuning a chassis without guidance is very tough.

With stock gearing 18/43 on a good track I can 60' 1.50's getting ready to go with a more aggressive sprocket set-up to help get out of the hole harder with less RPM. But check out how the bike sits 3" over, 2.5" of ground clearance. I am 220 dressed. Not a pro have been to the strip 7 times, foot shifting. Having a nice set-up helps. Short bikes are tougher to ride but build skill the fastest.

61" and no rubbing issues but the undertail area is nicely gutted for clearance.thats a great looking bike
You gonna need some more motor or nitrous,good air,some very good riding skills and great track conditions..9.99 is very possible..

So far ive ran 9.33's at 154 at swb on stock motor so Im hoping I can go faster than 9.99 once i stretch it
3.4 tenths will get me what I need, and Im hoping that traction wont be a problem with a power one race. But we will soon see, I will post as soon as I get it back together and to the track.
Those times were also in 2000+ DA air, so as soon as the temp drops around here that should help too. Wish me luck
