I have a stock stroke stock cylinder motor, with +4 timing, dune port, coolhead,vf4, shearer inframes. Nothing special really and I can pull away from my buddy on his 450 all day. It don't take much
I'd probably start 55 pilot 155 main and work down from there. Needle on middle clip and air screw 1.5 turns out. I'm running 33 pwk on a stock stroke dune port set up and I'm a 42 pilot 148 main and it's still a tad rich
I'll have to let u know next time we go up there. Usually try to hit there a couple times a year. Don't get to ride as much as I like with job,wife,and kids. Gonna buy a blaster for my 10 year old son so he can start coming along soon
I've got a driveline lockup to go in my 421 when I build it this winter also. I might have to pick your brain a little when that time comes.
Thanks for the invite on the ride that would be awesome. Have not ridden anything with that much power.
I was up in gladwin last weekend and my stock cylinder dune port with shearers was walking all over my buddies yfz450. He couldn't shake me in the trails either which made me happy about my suspension mods last winter
Remove carbs and take the bowls off to check jets. Videos on YouTube if you need them. Clean carbs and air filter real good. Tell us what you have. Also let us know what other mods you have
