Check spark check compression check your plug caps report back

Good start. Will you go custom pipes? What size engine? I believe there was a guy selling engine mounts for hybrids on FB.

I thought Tony Doukas would have your covered for Twister? That guy runs a tight shop.

Couple of guys running 421s with 28s on this forum. I am one of them. Only thing I would add to your set up is a pingle. The shop that built my engine (low port) there is no noticeable difference in max hp. Fuel economy and snap on bottom end is much better. go for it

Alaba a arms and yfz450 (newer) shocks. if your just buying shocks buy used floats

Your jelly! i made the bracket already for the shifter electronics, I have it attachingibg to my air box tabs. what would be cool is if you could think of a bracket that can attach to my stator bolts that can hold the shifter

thanks never heard of it. I will look it up. I want something that wont leave a mark on the chrome.

Damn!

I damn close to an inch from touching. Still need to put on outer wears but they’re thin. Should I be worried? Sent from my iPhone using Tapatalk

ya im just wondering for my set up. curious to hear how close people let the stinger get to the filters before they heat wrap?

So how close to the lstinger/headerbcan the filters be before you have to wrap?

High rollers yous are

Snipers don't work well on DL cylinders, at least from the dynos ive seen . Snipers work well on Redline serval motors but the ones ive seen have that weird dip. CPI have a real nice curve. Basically, I think it comes down to the guy porting the motor not the pipe. I would like to see dyno from another builder comparing pipes.

Stick type (though not as good) are cheap effective and easy to install

driveline is the best bang for the buck. Have them do the motor porting and use their crank. You’ll save a bunch. Have them add boost ports, they’ve been seeing big hp when they’ve been added. shearers, CPI work good on them.

Hope your crank was t damaged where the key way sits. glad you figured it out and was t to major. Lock tight that bitch and ride

Post a video !

When I upgraded my engine I went with the smallest carbs (28s) I could safely put on the engine. I did it for mileage

Look at the dirt wheels article on a banshee built for desert racing. You’ll need long travel a arms, stock length swingarm, Elka rear link or move your shock mount on frame (DWs article), large tank, dc conversion for big lights. Your pipes are good bottom end pipe for stock motor, I would go PC for mid range. Out of the box no doubt the 450 is better with a way better frame and geometry

I remember replying to that on FB not to do it.

What’s done to it now?

Didn’t you sell a set of Cascade silencers?

Hell ya!!!!! very happy to read this. You can experiment with pipes and try smoothing out the ride.

I believe the guy that won a set was shortly banned. GRR”s return to this site was very short lived...

Stock carbs handle that hp no problem. Save money and keep them. I ran 72 hp on stock carbs no problem
