Help me find the correct swingarm length
Like the title says, I'm in the process of buying a swingarm, and I'm not sure about how long I should make my bike. I rode all last season on about 64-65", and I really liked it. I was still getting the hang of it, but I was averageing 1.50 by the end of the season. I know I was getting better, but I think I could have done a little better with a stiffer spring and better valving. Anyway, I'm adding a lot more power this year (turboing my bike), and I'm getting a nice swingarm.
Hp will be somewhere between 250-300 whp.
I weigh 250 unsuited.
I'll be buying a drag shock and a gen II hayabusa spring
Hand clutch with Gann 2 stage lock-up
008 shinko
Track prep isn't that good on Test N Tune nights at my local track, but I really enjoy racing at Test N Tunes. Is it possible to go 12" over and still hook up, or am I dreaming?

68-72" wb.
I would use an Adams Performance arm. Adams arms have more room for adjustment to allow you to find the sweet spot than other arms I have seen.

Get at least a 2-stage boost controller. Get a 9-12" arm, and if all else fails use a M/T shootout tire.

It's all in chassis setup. Well, a lot of it anyway.
If you get a 12" arm that's the max length, you can always go shorter by at least 4". That would pit you at 8 over at a min. You need at least 8".

hmmm. Good point on the M/T shootout tire...... A tire is a lot cheaper then ordering a longer arm.

If your adams arm is in good condition and you want to trade it for a longer or shorter one with the same bracing it would only cost you about $300. That would be cheaper then buying M/T v/s shinkos over time.

Adams arm is nice...but no more adjustable than any other arm at equal length. Chassis setup and rear shock are a big piece of the equation...in fact, the biggest piece.
With crappy track prep you will need a nice tire, no matter what arm. Shinko 008 might be the cheap alternative to a M/T.

Adams arms are at least $250 more then an equally equipped Evil or Hardcore arm. I don't think I'll go anymore then 68" because the zx14 looks weird with a really long arm. I think 1000's look great with stock tails and a long arm, but the zx14 doesn't imo. I just hope that it'll hook at 12" over.

Adams axle adjustment is 4.5", most others are 4" and some mod'ed stock arms are even shorter. However, Mclntosh alumpro is 4" but has a 6" option.
I agree, chassis setup is more important.

By what I've seen and heard, the $250 extra for Adams is worth every penny

I don't know that adjustability is very important to me. As long as 12" hooks, I don't see a reason to ever go shorter. Hardcore is advertising 6 inches of adjustment on their arms.
Adams arms are nice no doubt, but that's a LOT of money for metal tubing imo.... I've always felt like motorcycle parts are crazy expensive. $1000-$2000 exhaust systems, $350 valve springs, $1000 swingarms, $5000 turbo kits WITHOUT intercoolers.... Maybe I should get into the bike aftermarket. Haha!! Rant over...

Why do you say that? Are you saying I won't go much faster at 68"? Or are you saying the potential traction problems don't outweigh the performance gains by a longer arm?
Also, I've been meaning to contact you about your fuel rail. Email me at gilberjj@gmail.com with the details and price shipped to 98501.

A. Its easy to hook a bike shorter
B. At 250lbs and that little of hp you dont need to be 68-72". Your weight will help keep the front down.
I would focus more on getting it lowwww then long. If your center of gravity is still sky high it wont matter how long it is.
Just my views on things, im sure others will disagree but whatever.
Ill email you on the rail.

If you mostly race @ 1/8 mile tracks your 60' and 330' is much more important then @ a 1/4 mile track. If you want to keep the bike streetable you can only go so low. @ 265lb suited you would get much more traction @ a longer wb then 165lb rider. @ 265lb you will be force to set back more on the bike then a 165lb rider which will cause the bike to wheelie easier. If 12 over is your target. I would get an arm that is some were in the middle. When I make h.p. changes I often need to make not only chassis but sprocket changes also. Therefor, I consider axle adjustment to play around with gear ratio without running out of arm one way or the other. I'm not disagreeing with Compton ( because he is much faster than I!) Just somethings to consider if you haven't already.

If it was a slider bike maybe, but i wouldn't say the same with a single stage lockup.

I think a 6-12" over arm would be the best of both worlds.
8" is about 65" right???
