Swingarm Length help...

[Valin]

Guys, I am currently working on a project bike, but I am also going to be picking up an additional swingarm to set the bike up for 500' drags off of a clay starting line. At these races, we will be allowed to run chisels in the tires, so the bike is going to leave hard. What length of swingarm should I throw on it to leave flat? 10"? 12"? I will also be lowering the bike.

 

Setup specs:

 

4mm longrod stroker

stock cylinders, booster intakes, triple exhaust ports, dune port (roughly)

Toomey T5's

Coolhead with probably 18cc domes? (going to run VP C14 race fuel) - I'll figure that out later....

V-Force Delta 3's

33mm Mikuni TM Flatslides (From a yamaha SRX700 snowmobile, modified spacing to work on the shee)

K&N Filters

 

 

What do you guys think?

+6 should be fine for your setup.

You know what swingarm your getting yet. hit me up when your ready. Modquad makes some drag carriers for there swingarms. u wont find them on the website though.

this is going to depend on whether or not you want to run a wheelie bar.

prob a +10 if your not runnin a wheelie bar , depends on ur weight. maybe +6 or +8 with bar . rheres acouple of guys on here that race clay tracks with spiked tires.
