swingarm size

[kawiking]

im building a 421 cub... i have a plus 6 swingarm right now.. i trying to think if i should go +8 or 10..

 

 

this is pretty much goin to be all drag.... i dont care if the front comes up alittle , just dont want it to come up alot.

[theshee]

Id go with the +8. Thats what I ran on my 421 and it wasnt a wheelie machine and it felt about right for the motor.

id rather go with a +8... my buddy has a damn +6 on his 10 mil. and it s a wheelie machine. im wanting to drag race mine on sand/dirt tracks and sand bars and little sahara.

 

does anyone have a wheelie bar for a a stock carrier set-up.. i see alot made for round house swingarms

like theshee said go with the 8...bigboy ran an 8 on his, however he did run a bar :biggrin: although mine doesn't put the numbers out a 4 mil cub does i run an 8 on mine and it is pretty controllable, comes up sometimes but not like it did with the six.

yea.. travis told me he ran a +8.. my buddy has a 10 on his 4 mill. he said it would pull the tires off the ground alittle at little sahara. even if it comes up a foot, thats fine with me. i just dont want it to come up to much. im running 12 paddle haulers on it.... i think ill prob go with a 8

Now you know why my swinger is so big with the motor i'm putting in it

 

although i'm gonna have 14 paddles on mine cause i'm a skinny bitch

The whole swingarm length stuff has my mind boggled. I'm going to be looking for a

wheelie bar soon. I bought travis' +8 and drag axle for the cub I'm building.

I ran the arm and axle on my dune port before I retired it and I could still get the front

end to come up a lot more than a foot off the ground. So im pretty sure its

gonna be worse with a cub on it. You may need more than +8

or run a wheelie bar. or hell, both.

I ran a +12 swinger with 13pdl extremes on my 421 . It would still lift the front up if I wasn't watching what I was doing. Baddassbanshee479 used a +10 last year on the track and he pulled the front up alot off the line. I think he's gettin a bar for his +10 this year.

[kawiking]

well f@ck me... i guess im back looking at a +10

nice avatar cody !!!!!! :biggrin:

Correct me if I am wrong shayne, (just my asssumption, ive never actually raced on a track) but track traction and sand are way different arent they? I think you get more traction on a track. I would still go with a +8, thats what my 421 had it it would just blow the 10 paddle extremes off and wouldnt wheelie... If you were building a bike to go in a straight line on a track, yeah go with the longer one, but where you are going to dune this bike, I would go with the 8.

[kawiking]

well..not really much of a dune bike.. it sits pretty low, and im really thinking about putting it on alky. pretty much just going to be used for drag racing on sand bars , are local dirt/sand track and maybe i can get some ice tires and do some drag racing in dirt.

were ever anyone wants to race... acouple of my friends are running asphalt .. not sure i want to go that away.

 

i know are river bed sand is alot lighter than little sahara sand.. i had 9 pad tripple buff haulers on my lightly ported stock bike and it would spin the crap out of them, with a +6

 

kiel... i might just buy that +8 u have .. if its not enough.. i'll save up and get a +10 round house style.

i wounder if my +6 brake line will stretch another 2 inches ???? hmmmm

[kawiking]

and it will prob be getting drag ported .... :cool:

[theshee]

I really think that you will like the 8 and im not saying that because I have one for sale... in all honesty, I think you will like the 8.
