thack

just took .030 off mine .nice mod for little money being i work in a machine shop and done it my self

my moto fast is bigger i thing dyno port is too

ok the coolant is coming from the overflow tube were it runs up under the handle bars in front of the tank coming from the bottle there is one going to it from the radiator and one coming from it .but like you said it seems to be buiding up preasure .i took the radiator out and had it checked no leaks.what i cant figure out is why its coming from the over flow tube and the over flow bottle is only half full but when i check the radiator its a couple inches low.im confused too seems it would fill the bottle before it runs out the over flow tube .it only does this when i stop or right after i shut it off .i got the head from a guy on this site and was told it was i good working order from a running bike i checked to make sure it was flat it seemed ok to mee but i never checked it with a feeler guage to see if it was warped .it acts like thats whats wrong.loosing coolant and preasurizing the system .so when i shut it off or stop it pushes the preasure out the over flow

i put a decked head and advanced my timming and now it spit coolant from the over flow.but whats wierd is it doesnt fill the over flow bottle up .i ride on a track and it does it drag racing and it doesnt.my over flow bottle level never changes. but my radiator is low after a ride .the bike doesnt seem like it getting hot.almost acts like a leaking head gasket but its brand new..the head is deacked.030 +4 timming .280 dyno jet mains and needles clip 4th from top with washer stock piolits 2 and 1/4 turns out at 1000 feet elevation

i need 290 and 300 dyno jets jets .or does anyone know if you can run mikuni jets with dyno jet needles

stock bike i want to say 250 260 range thats what my friends has in his with dyno port 2 into 1 at 1000feet

if they are the ones in the pic with guards im very interested

mine i doing this too when your sitting on the bike it leaks on the right pipe.i rolled it a few months ago and it landed on the handle bars .ithink i may have a leak in mine.

im running the high test from the pump .my compresion is about 150 i think any more than that and its good to run a little av fuel with it

we are going that weekend ,we will be in the campground at the entrance to the park

what mods you runnung and what elevation.im running 280 mains dyno jet needles 4th clip from top withstock piliots 2 to 2 1/2 turns out im at 1000 feet mods are in sig .mine runs perfect.

it may not have come up in a search .but alot of guys on here say thats one of the first things to look for with carb problems . ive never searched for it but ive read it in several posts

i hate it when that happens

no i dont think i did just toped off put cap on and started it up .thats what i figured it was.

just got to realy ride my bike with the new head and timming plate after riding it burped a little coolant like it had an air pocket or something . it wasnt boiling or nothin just like i over filled it .
