Trying to decide on what 350cc kit to run.

I’m sure you’ll be getting a pm with Pete’s number

Pm sent

[Hutchracer]

Thank You sir!

Cant wait to hear what he has to say.

[hickwheeler]

He does all the machine work and porting

[The norm]

Pete is a really good guy to work with. He takes pride in his work and will tell you straight up what works and what doesn't. He will also tell you what to not waste money on.

I've been talking with him for the last hour and a half. Just like you're saying he is very informative. He is telling me what is going to work best for what I am looking to do and also telling me what is a waste of money for the build that I want. I am super excited to start getting stuff ordered up and getting it down to him!!!   

Thanks again for giving me his info and letting me know that there is such a good builder here in the PNW!!!

[hickwheeler]

You will be happy with his work. Keep us informed on your build

[Hutchracer]

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!!

[The norm]

I have the 391 built by Pete. He built mine to be a torque monster.  Make sure you tell him the type of riding you do and he will port the cylinder accordingly. I ride mine in the dunes and love dropping in to tree holes so it works perfect for me.

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!

[Hutchracer]

As soon as I can get the 370cc Cylinder from Eddie @ ESR I'll be driving it down to Pete.
I'm going to try my best to be able to have it finished up for this coming season of riding. Our first trip is usually at the end of March.
I'm sure it wont be 100% completed by then but I would love to have the motor at least done and hopefully dyno tuned.
It is a lot to ask between now and then but that is what I am shooting for. There are a few parts that aren't exactly cheap though.
I think besides the obvious cylinder and case work, the Exhaust and the CR Ignition are going to be the bigger expenses I think.
Then it will be the basics like a high flow water pump, clutch basket and clutch, and a few other goodies.
I wont lie I haven't been this excited to start a build in a long time!!

[hickwheeler]

There is no need for high flow water pump. I good radiator is good insurance. I ran my puma at the meet up in August. With nothing special. Just stock pump and rad. I do have a afco in it now for added insurance.

[The norm]

Yeah I agree with Gene on the water pump and radiator. If tuned correctly Pete's engines run pretty cool. 185° is about normal on my 391.

[Hutchracer]

Good to know I do have an Aluminum Radiator.....to replace the stock one.

What's an Afco? I could be totally brain farting here it has been a long day for me. Haha

[havinnoj]

AFCO is just a brand of aluminum radiators like PWR, CBR, etc.
