Smaller cc domes or a thinner head gasket. 135 psi sounds perfect to me though, paying for race gas is so expensive and sometimes even finding it is a real pain. Its not fast enough?

ATV ban here in Alberta because of a virus, go figure. My quad wont see woods, just open road and logging roads so im running different pipes. My builder insisted on a dual pingle so I listened, my understanding is that that would be enough, so I don't need bigger bowls. Run your FMF pipes for now and upgrade when you can.

I would not run it with stock carbs, mine has 28 pwk with a dual pingle. 23-24 cc domes will be good for all types of pump gas. For where yu ride I would look hard at the SLP pipes, tons of low end power and torque that comes on super quick for those hills with no run up.

GRR is Grand River Racing or Rocket pipes. Pro Circuits are awesome mod range pipes that make good power. If you want more top end try CPI (good everywhere) or Shearer (the most rev) If you want more bottom end with huge torque get SLP

Not too much difference from 26 to 28 really. You’ll be up on jets by a bit.

What size is tour engine? Hard to beat PCs if you have a smaller engine.

FAST for everything

If you already have stock carbs I’d keep them

DL, I think the power is equal or very close. Nice have the stock look also.

Buy the swing arm mentioned above. Sweet deal! you definitely don’t have a lot of money to play with. Get Alba a arms and a decent shock, then if you can get a stock engine and can afford it go with a stock cylinder stroker

CPI

Fireball has updated their long travel a arms. That’s a solid a arm and there is a BHQ discount. lonestar DC Pro would be my choice and the fireball. fox evols are super light and infinitely adjustable, great choice also being that your in America you could save money by buying a high quality a a sauna shock like Stadium or Elka stage 5 i would think shearer big bores would be better than small bores for your engine

You'd be way way better off buiding a hybrid

Here’s some real good advice. Sell the roller and buy an already built bike. You’ll save over half of what you’d spend building it.

Here in Canada I just seen an article that said best case scenario things are back to normal (no social distancing) in July. if that’s true, and seeing the numbers coming out of the US, I wouldn’t get my hopes up

Well trail and street are different set ups so for your case you’d want to compromise. For trail only you’d want a low end pipe like SLP, for street racing you’d want a top end pipe like Shearers. if you don’t have the money, port your stock cylinders to a dune type port and weld the stock crank. If you have an extra couple of hundred get a Driveline High port 392 set up or get a 4 mil crank and do a stroker. reeds go VF4 a great mid range pipe are Pro Circuits. if you have a lot of money build a serval and ask the builder his pipe preference

Shitty. I don’t know then. RDZ or K&T maybe

Check the sticky on the jetting section, youll find someone running a similar set up.

Jeff, always gets what you need.

I’ve seen a graph of a loss of 2hp on the bottom and a gain of 2hp on top. So not a big deal. Throttle response will probably be the bigger difference. Regardless it’s a good set up for that engine and pipe combo Sent from my iPhone using Tapatalk

Lose bottom but will gain top end. Id run them...

FAST although you wont need them with a Pingle

You would take a lot of guess work out by going to a dyno shop and trying different timing and jetting. At least you could se on the AF meter where your at in regards to jetting. if it’s not timing or jetting I would think a done change would be in order

so whats the perfect number for rollout? Whats the hindrance of a rollout that small? Not enough rev?

Ok Skeet, I was mistaken. I have Haulers not Extremes, so that's disappointing. And the rim is a 9 inch and I just measured roll out at 60 inches. What do you think? Keep on looking for some Extremes or these good enough? Small rollout eh?
