WestSideRiderz15 Posted August 4, 2010 Report Share Posted August 4, 2010 I pulled my cylinders and had new pistons put in with a bore job. My banshee spits coolant out the over flow tube coming from the overflow reservoir. I use a temp gauge from an RC car (IR) and i dont believe my banshee is overheating and the bore job was a simple .75. I am currently jetting my bike to find an optimum so i dont believe that it is running lean. I heard on the forums that if you removed your head gasket and reused it, that pressure from combustion and compression can cause thecooling system to overpressure. Is this true? Does anyone else have problems with reusing a head gasket? +air lid removed, tors eliminated, .75 over, stock pipes and carbs+ Quote Link to comment Share on other sites More sharing options...

I reuse the same head gasket because one of my orings on the coolhead was leaking antifreeze into the right cylinder. So I reused the head gasket & installed my stock head & thats when this BS started happening. I ordered a new head gasket & installed my stock head & the antifreeze is still flowing out my overflow hose + making a boiling noise.

WestSideRiderz15 Posted August 5, 2010 Author Report Share Posted August 5, 2010 Does it spit it out when you first start it or after it gets hot? It seems to be as its warming up to hot. I popped the cap before i rode it today and the radiators a lil low on coolant but the overflow has lots. Could it also be a radiator cap issue? I took it for a ride jut now and read the temps with a heat gun. 180 engine, 150 radiator, 245 exhaust I dont believe i am lean, if aynthing i think im rich because my bike is preety stock and i am using 250 mains On a side note, i warmed the bike up and it was bogging off idle (assumed rich condition). So i ran the screws out to max (2.5 turns) and it didnt help much, i just ran it again with 1.5 turns and it runs much better off idle. This seems contrary to the norm.

vbanshee Posted August 5, 2010 Report Share Posted August 5, 2010 ok fellas ... i had this problem and got it fixed first thing its a stupid mistake but a lot of people do this did you locktite and do three torque sequences to head. make sure if not theres no compression holding in the coolant. if you did that then you have a blown head gasket/ o rings. but most likely its the first thing i said i had chris on here help me out after i re torqued it all it was fine Quote Link to comment Share on other sites More sharing options...

Ill pull the head real quick and reseat everything. My headgasket was preety new when i took the head off last so i dont believe its blown. But i can believe the head isnt flatting it correctly. I did a two stage torque on my headbolts and retorqued after break in.... Quote Link to comment Share on other sites More sharing options...

Stock style Banshee head gaskets SHOULD NOT BE REUSED EVER, that isyour problem.They are made to be installed once, if it has been toqued down and gone through a heat cycle you can not reuse it. If it was toqued down and never started, then you can pull it off and put it back on. Quote Link to comment Share on other sites More sharing options...

WestSideRiderz15 Posted September 7, 2010 Author Report Share Posted September 7, 2010 Solution: Received my head gasket a few days ago. Have gone on two rides now with no over flow issues so far. I believe the old head gasket was the cause of the overflow issues as expected. I re-torqued the head in the 3 step manner (10-15-20) as usual btw. For those curious: When the pistons are compressing, a minor bit of the pressurized air leaks past the head gasket and begins to pressurize the coolant system. This makes it appear as though the bike is overheating. Quote Link to comment Share on other sites More sharing options...
