great.. new issue

[brian102]

so i went to the silver lake sand dunes this holiday weekend, and was wondering where my jets should be at. fmf gold pipes with stock silencers (only ones i had with spark arrestors) filter pod air filters, mild dune trail port, .20 over cylinders.. i trail rode with it the day before and it stayed right around 160 for water temp, the next day it completely changed, it kept spiking up, antifreeze was leaking out the overflow tube, i would get to top of hill and there would be smoke coming off pipes from water dripping, and it really seemed lack of power,seemed like it took forever to hit power band,but once it hit seemed ok, but could never get into 5 or 6th gear, wich last year before i did these new ports and cylinders i could.. i should be making more power now not less! lol

 

thanks

sounds like your leaning out,if your over heating and losing power,I would check for air leaks first and go from there,hope this helps

Did you re-jet after the porting? What are you at now?

[sleeper06]

List your jets mods,do a pressure test,6lbs-6min,coolhead?

[brian102]

i did bump up two main jets sizes, 290 is whats in there. listed all the mods in first post, nothing else done to her.

[sleeper06]

With those pipes at sea level i ran 340 mains,27.5 pilots,needles 4th clip from blunt end,might be a lil rich depending on porting might go to like a 320 but start rich you might need it with the pods

ok i think i might have other problems to.... i cant keep water in the radiator...i filled the radiator, filled the resv. it just pee's right out the overflow tube. like a steady stream, and its bubbles in the resv tank,.. so i took cap off to see if any water was being moved around in the radiator, i went to start it and itjust shot water all over the garage.. what the heck?

so i took head off and there was water in one cylinder, and that side the pipe was full of water... so i guess i re do it all, im taking the head intomorrow to local machine shop see if its flat or not.it has been milled a little by the prev owner, maybe they screwed something up!

I've have a couple of buddys lean thiers out to much and get to hot and blow head gaskets and thier stock heads were milled to.sorry to here what happened,I would have the crank rods check out,make sure they are not bent from hydro lock,since you had water in the cylinder.
