bansheefourseven Posted November 20, 2006 Report Share Posted November 20, 2006 I was running the shee around the backyard last week it was around 47-50 degrees outside and after around 30 min or so it started puking coolant out onto my front right pipe from the overflow tube. I never much got it out of 3rd gear but I just dont know why its overheating. I just put it back together a month or so ago and have a few rides on it since with no problems. I checked my impellar when I rebuilt the top end and it was fine no broken fins and spun fine when kicked over and no coolant in the crank case. Are banshees really that hard to keep from overheating in 50 degree weather? Its bone stock other than the new prolites and rings. Stock jetting stock everything. Im gonna try a high flow impellar and engine ice but it just doesnt make sense that it would overheat completely stock in 50 degree weather? I know your supposed to rejet for cold weather riding but I didnt think you had to if it was just a little cooler than normal Help me out. any suggestions? all gaskets and surfaces were imaculate when the topend was rebuilt what else could it be. And what kinda compression should I have stock @ 400-800 above sea level (general michigan elevation) I was reading 100 in both sides before rebuild and 125 after rebuild Quote Link to comment Share on other sites More sharing options...
dynodon Posted November 20, 2006 Report Share Posted November 20, 2006 Souds like your "stock" impeler took a shizit to me, they are known to strip the plastic gears. I would pull it out to look, if so, spend the extra few dollars on a billet one and be done with it Quote Link to comment Share on other sites More sharing options...
bansheefourseven Posted November 20, 2006 Author Report Share Posted November 20, 2006 (edited) Im almost positive the gear is fine I kicked it and my buddy tryed to hold it to see if it was stripped and it wasnt it spun fine every time. I can even see it flowing with the radiator cap off! Do they make a metal gear for it All Ive seen on ebay is the impellar attached to a shaft but no gear with it? No good to just pay $70-$80 for an impellar if the plastic gear it goes on is stripped right? I dont want another plastic one, who makes a metal one or one less prone to stripping?

thegroup Posted November 20, 2006 Report Share Posted November 20, 2006 i would replace that piece of cheap fuck anyways. that was the 1st thing i did when i got mine. also, make sure u get as much air out of the line as possible. just like in a car, if an airpocket gets caught, itll overheat quicker then shit Quote Link to comment Share on other sites More sharing options...
akita8 Posted November 20, 2006 Report Share Posted November 20, 2006 If you just put it back together it could be the head gasket leaking letting the cylinder pressurise the cooling system. Quote Link to comment Share on other sites More sharing options...

B.S Ride trails slow behind my buddys Brute all day and never over heated. Over heating means there is a problem. Not enough fuel, air leak or something.

scooter Posted November 20, 2006 Report Share Posted November 20, 2006 how much is puking? from what i understand its normal for them to belch a few drops now and then but mostley when ridden hard Quote Link to comment Share on other sites More sharing options...
bansheefourseven Posted November 20, 2006 Author Report Share Posted November 20, 2006 Not much just a little bit or just enough for me to smell the collant steaming off the pipe. I rode the piss out of it after the rebuild through the trails and it didnt do it once. I was hitting a berm in second in the backyard and wheelying out into third and then shut n her down . Its about a 125' stretch so who knows Im gonna get the impellar and gear and run some engine ice and hopefully that takes care of it. If not im replacing the radiator cap and seeing if thats the problem. Other than an engine pressure test how can I check for leaks? Does the carb cleaner sprayed all around the engine while running trick work? Quote Link to comment Share on other sites More sharing options...

Try spraying ether around the carb boots, card tops,reed cages,anb bases of cylinders if it starts to idle higher, then you found the leak, And could you hear it boiling through the resvoir?

bansheefourseven Posted November 20, 2006 Author Report Share Posted November 20, 2006 Once i smelled coolant id shut her down and Ive never heard it boiling so to speak at all just about less than a teaspoon full spit out onto the pipe thats all Quote Link to comment Share on other sites More sharing options...
Hollister_Hitman Posted November 20, 2006 Report Share Posted November 20, 2006 I just changed out my stock impellar to the mod quad high flow one. The stock one looked fined when I took it out. my radiator used to spit a lot even if it was like <70. I rode it yesterday and didn't smell anything and it was like 80.

375hp banshees Posted November 20, 2006 Report Share Posted November 20, 2006 B.S Ride trails slow behind my buddys Brute all day and never over heated. Over heating means there is a problem. Not enough fuel, air leak or something. B.S. you don't have a temp gauge do you, I'll bet you run ALOT hotter than you think. slow trails or doughnuts w/o airing it out your going to run hot.

Did not say it was or wasnt running hot.Could be? But did say no over heating.Over heating meaning boiling over not just a little hot. I seen you have a temp gauge. What are some of your average temps on a trail ride? Edited November 21, 2006 by 65983cobra Quote Link to comment Share on other sites More sharing options...
