Ideas on swinger length?

Well guys, I have got my housing built to accept an eccentric carrier, and I think it turned out quite well. It started out as .250" wall, 3.75"OD 4130 chro-moly tube. I had to bore the inner diameter to 3.405" for a 5 thousandths slip fit, then used the rotary indexer on the Bridgeport to cut the clamping reliefs. 0042.jpg0052.jpg0062.jpg

 

I am trying to decide on how long I should make the arm. I know that you usually go shorter for trails, which I ride in the summer. During the winter we're out on the lake with bolted tires, when I could see that having a longer duning style swinger would help. Add too the fact that I'm building a new 4mil and I'm confused as hell as to what I should do?

What sort of engine do you have in your bike?

I guess nothing special, compared to alot of guys around here, 4mil hotrods crank, 795 wisecos, coolhead yet to be cut for the stroker, vf2 reeds, with a single 35 as of right now. I don't know of I want to stay with the single carb as for right now, or even if it will be enough? Oh, and can you see the pictures?

I don't know about running on ice, my thinking is you will hookup quite a bit from pictures i've seen of ice tires with those nasty looking screws in them. I know mine with relatively same engine in dunes with paddles still wheelies with a +4. You can still ride a plus 4 around it takes little more throttle control and weight shifting to get the ass end around like a stock length, but it is do-able. Had a +6 on, big difference, lost a lot of all round riding, bigger pain in the ass.

 

+2 to +4.

I used a +2 for my duner bike and loved it. It wasn't too long that I couldn't trail ride it either.

I run a +4" arm on my red bike and it is completely duneable (including tight trails) and jumpable. In the past the engine I have had in there has been right around 100hp. :thumbsup:

I never used a +4. My dune engine was only about 70ish for HP. I went from a +2 to a +8 when I turned my bike into a dragger.

it can depend on your riding terrain/style what you want for lenght. if you are pulling into a wheelie than you need to extend it, if not then shorten it. it is usually better to shorten it for the woods. i am running a stock lengh swing arm and have no problems, personally i would like to go -1 on my swinger but i would have to change my rear shock and link and that would cost to much$$
