Re: Trying to decide on what 350cc kit to run.
So after talking with Pete for a while once I can get my hands on a ESR 370 Engine Builder Cylinder kit I'm going to have him build me a 391cc. He said for the $ it is the route that he would go for cylinders. I'm going to order up a 4mil Stroker Crank this week and then basically just waiting until Eddie gets caught up and can make me a cylinder.

Eddie said he is a little behind on stuff but Pete said give him a few weeks and he should be able to produce a cylinder. Most likely going to put my YFZ 450 up for sale now as that was just a temporary ride until I could find a good 250R. Granted I pretty much built that thing more than I really needed to. So instead of a 50hp 4 stroke I should have in the neighborhood of 75-80+ hp out of the 391.

I'll be running a 40.5 PWK carb and a LED 350G exhaust. So I'm hoping to be in the mid to upper 70s for HP.

I can't wait to get this build moving along!!

You're going to be a happy camper. Pete is responsible for some of the best running 250r engines in the business. Especially when it comes to dune/drag setups.

Keep us posted! There haven't been many engine build threads on here in awhile. So we'd love to see one!
