trickedcarbine Posted April 14, 2013 Report Share Posted April 14, 2013 Could be that the Bike was ran with out coolant..... Or, the bearing went bad and the thing death wobbled till it was mush. But to me... That is a product of lack of maintainence. Coolant, especially cheap coolant, has a tendency to become acidic and if not changed or flushed. Thin aluminum like our Billit waterpump don't stand a chance. Quote Link to comment Share on other sites More sharing options...
Pastrykiller Posted April 14, 2013 Author Report Share Posted April 14, 2013 This was not a billet pump. This was a factory piece of shit. The intent was to show why a billet impeller is a no brainer Quote Link to comment Share on other sites More sharing options...
ClayAiken Posted April 14, 2013 Report Share Posted April 14, 2013 Oh. i thought that was a billet impeller. Quote Link to comment Share on other sites More sharing options...

SpecialEd 05 Posted April 15, 2013 Report Share Posted April 15, 2013 I pulled mine down and replaced the stock impellor to a Chariot billet impellor. The stock impellor though was in perfect condition as was the plastic drive gear. This had been run for 7 years with the only coolant change 12 months before the tear down. Could heat have cooked it and it became perished and brittle? Quote Link to comment Share on other sites More sharing options...
Chris327 Posted April 19, 2013 Report Share Posted April 19, 2013 had a riding buddy fry his banshee a could times. One time he melted his impeller just like that. he should run higher octane gas to keep it cooler Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted April 19, 2013 Report Share Posted April 19, 2013 why do you say higher octane fuel is going to cool his motor? Higher octane fuel actually burns LONGER and more controlled to eliminate pre-ignition due to excessive combustion temps. Now...if everything is correct with the coolant system....either the bike needs to maintain forward momentum to keep air flowing over the radiator as there is no fan, or the engine is being lugged in too high of a gear. In which case down shifting and actually revving the motor up a little higher will actually bring down the temperature. Quote Link to comment Share on other sites More sharing options...
LilJockey481 Posted April 19, 2013 Report Share Posted April 19, 2013 I've seen elevated temps from clogged radiator fins, if its packed full of mud and grit it will cause catastrophic temps. Also if ur doing prolonged riding in high temps I'd consider engine ice or wetter water should help lower your temps some Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted April 20, 2013 Report Share Posted April 20, 2013 he should run higher octane gas to keep it cooler Negative ghost rider..... That is just a myth. Only reason some people think their average motors run cooler on race fuel is because it typically isn't actually burning all the fuel completely. So it won't produce the heat. In turn there is lost power and excessive money spent on something not needed. Motors designed for race fuel will risk running hotter due to added compression and timing. Obviously some race fuels will run cooler due to evaporation rates but that is a completely different subject. Quote Link to comment Share on other sites More sharing options...

I think the implication here is that the motor needs higher octane fuel to fight detonation. Detonation will cause a lot more heat than a properly running motor will. So he either needs to re-jet, back out timing, or increase octane. Quote Link to comment Share on other sites More sharing options...
SOUTHTHIRTY Posted April 20, 2013 Report Share Posted April 20, 2013 Was this a alky bike or race gas ? And do u guy think it matters? ..I switched to alky and my bike runs very cool Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted April 20, 2013 Report Share Posted April 20, 2013 alky will run almost COLD compared to gasoline. A lot of guys have been known to have issues when it comes to warming the bike/fuel up to make a run as it will begin to cool down between warm up and actually lining up at the start....
