Ideal swing arm length for dune and trails

[Abtx]

Planning on getting a exended swing arm and I wanted to go +6 but I was wondering what the ideal length for this set up, more or less

[SandSlingerOR]

+4 would be better.. but if your doing trails to , go either +2 or +0. I dune with a stock length & it's perfectly fine, I wish I actually gone with a -1 instead.

Trails? Stock. I got a plus 6 and it freaking Sucks for anything except keeping the front down. I'm going back stock length ASAP.

I can feel the difference of my stock vs +2 in deep tight dunes. It's more effort the longer you go

I like my +4 - I think it depends on power and how big of a dude you are.

 

Mine is 80+hp and I am 200lbs.... a +4 is comfy and still nimble.

No. I'm not a drag racer, so I can utilize the Power Valves.

Good. I didn't know they made that kinda power with them still installed.

As long as the valve is functioning and opens to the top of the port, there is no reason it shouldn't on the 500+ CC Cheetahs. All that info about the intakes is irrelavent on a motor that size as each cylinder is actually over 250 CC and there seems to be enough transfer volume to move it. I personally think it he Cheetah is not a drag motor, and guys building them for drag or hill shooting should just be doing a DM. The 250R guys have proved the benefits of power valves for decades in rec riding and various forms of racing other then drag racing.

Also almost every single 2 stroke dirtbike ever built.

Shhh, enough logic. Back to +12 swingers in the trail.
