4" over or 6"?

[gsx1300rr]

I need some experience based recommendations, I recently built my bike & put a RCC turbo on it- 267hp and 150 tq. I talked to a couple guys with a stretched busa & zx14 (non turbo bikes) who were stretched 4" over and they both could take off like a bat out of hell (running mid to high 8's) and the one guy said 6" over just made him spin the back tire. My gearing is 19/43 and I still pull the tire up in 3rd

Does 4" sound like a better choice or because of the power should I go 6"? I do a lot of roll ones, maybe launching it a little. I would like to take it to the track maybe 2-3 times but for the most part it is completely street ridden. Any thoughts on where I should start?

4 is plenty. When I was around the 260 mark I stayed only 2.5 to 3 over.

Perfect, thanks for the info. I will go with 4". Are most of the swing arms adjustable for say 4-9" or 4-6" or are they set to one size? When I get a innercooler I plan on turning the boost up quite a bit and if I can spend a little more now and avoid buying 2 swing arms I'd do it.

There are all kinds of swingarms available. Some have a short adjustment and some a wide adjustment. Since your main use is still the street I would go with a +1 to +5.

Terry does great work and he's a super nice guy. Tell him Ken says "Hi".
btw, I have the same exact arm you're thinking about.

Terry did an awesome job on mine. I absolutely love it. You won't be disappointed.

Very cool! Can you post a pic? I am curious to see what it looks like on the bike. I am ordering it through the guy who built my bike (Rick @ Ricks Custom Cycle.) so I probably won't have any interactions with Terry. Although, when I was researching the swingarm I did find TONS of positive feedback about Terry and his customer service. Sounds like a good guy.

I guess it will be 2-3 weeks before I can get one here, install it and post pics though.

You'll love it! Mc stepped up his game a few years back and has become the best in the business since then. I gotta back Ohio boys lol! As for length, it's all in the set-up. I was 6 out, and was at the point I was either lifting or blowing the tire off. I went 2" longer, and re-adjusted my shock. Just gotta go for what works best, but if your street riding alot, keep it under 8. I reccomend, no more than 4-6 if your a curve rider

Nice, I like the length! Is that +4? I will def not go over 4" to start. I want a a good balance of performance/streetability for the HP it has. The swingarm should be here this week if not early next week, as soon as I get it I will put it on and post a pic.

I just uploaded a little footage from sat on youtube. As you can see, the stock wheel base just doesn't let you floor it unless you are in 3rd.

It's set at about 4.5" in the pic.
