SHEESaBEAST Posted July 4, 2005 Report Posted July 4, 2005 Alright, I just bought a sweet Banshee, you can see my list of mods at the bottom, the main one being a Trinity 420 big bore long rod, and I failed to mention (actually, I didn Quote
locogato11283 Posted July 4, 2005 Report Posted July 4, 2005 ok sounds like you are a little confused here. first off does that head have o rings or use a gasket like a completely stock banshee motor? if you have both installed its not gonna be right. im sure that it is an o ring type head. sounds to me like the fucked up o rings OR head gasket was pressurizing the coolant system and pushing it out the over flow. did you install both a gasket and o rings when you re assembled it?? if so, thats your problem..

SHEESaBEAST Posted July 10, 2005 Author Report Posted July 10, 2005 alright, the overflow problem isnt that much of a problem really, i keep it cool and it is probably just my radiator cap being screwed up. And i know for a fact that i need both o-rings and a head gasket because trinity told me so. next problem, i have run into the issue of it bogging down and just lacking any sort of power at all, it gets ready to hit its insanely steep power band and it just wont. im pretty sure its not a carb issue, and im pretty sure that its not misfiring, my compression is at 140 ish, now a stock banshee this might be ringt, but i have a 420 big bore and i dont know if it is righ. also i changed the spark plugs, took of the air filter, messed with the pilot needle, and messed with my air fuel mix, none of it worked. the only thing i can think of is to replace my gas cz my mix might not be right, and clean my exhaust. ANY OTHER SUGGESTIONS??????? Quote
superchicken Posted July 10, 2005 Report Posted July 10, 2005 does it run fine when its just started.meaning can you get it in the power band when its cool.if so,it sounds like its overheating.i wouldnt mess around with the jetting untill you get the gaskets and orings replaced.then go from there.another thing is sometimes the over flow will leak out cold coolant.its the nature of the beast,but it will do it in moderation,it wont spew it.

wayfst Posted July 10, 2005 Report Posted July 10, 2005 ok dude, you've got problems. first is this the copper head gasket that goes with their stage 4 head? if so did they give you the proper sealant to go with it? on my bike i have this very thing, but it's usually it is reserved for really big bores. spitting cold coolant is a bad sign and could explain our other problems.

SHEESaBEAST Posted July 10, 2005 Author Report Posted July 10, 2005 ok like i said the coolant isnt that big of a deal, its the bogtging sort of that is pissing me off, the coolant might just be my radiator cap being screwed up. and ive replaced the head gasket, with the copper one from trinity, and a set of o-rings they gave me, it is getting warmed up, and if i were to take apart the top end, would my problem be evident???

wayfst Posted July 10, 2005 Report Posted July 10, 2005 spitting cold coolant IS a big deal. let us fix the bike before we try to repair the performance. now focus and answer my question. Quote
Bansh88 Posted July 10, 2005 Report Posted July 10, 2005 Mine used to spit out the overflow all the time. A few people told me to not put more than the minimum amount of coolant in the resevoir. That worked! I don't run with a resevoir at all now. Still no drippy. Nothing noticeable at least. Quote
SHEESaBEAST Posted July 11, 2005 Author Report Posted July 11, 2005 ok, trinity gave me a new copper head gasket, a set of o-rings and nothing else. should they have given me something else? and my compression was at 140, is this a bad thing? and if i were to take the top end apart, would a problem be evident? also, the coolant spitting is slowing down, it really doesnt do it that much that i can see, it is when i ride it hard before it is really warmed up, then it drips, but only like 5 or 6 drops. the only thing i did between when it started bogging and started bogging was refill the coolant system. can this have caused it? im going to drain my coolant, and my gas and start over, but i cant imagine that that is a problem. can a bike have a blown somthing and still start on first kick every time, because if something is blown, other than a head gaasket, wouldnt it affect the capability of the bike even running? anyway theres some more info.. thanks alot for your help so far!

wayfst Posted July 11, 2005 Report Posted July 11, 2005 no the problem wouldn't be evident. ok, let us run throught this, first anneal the gasket- that whole heating and quenching thing. clean the gasket, i used fine grit sand paper. apply a light coat of 3-bond 1211 (tried yamabond 4, didn't work) torque the head down, for the banshee with this gasket you add 10% so 22 ft pounds. wait about 30 min and retorque. let stand for 72 hours ( 3 days) and warm her up (don't ride) let her cool and retorque, repeat. now you are ready. i replaced that gasket in mine 3 frickin times, do it this way and maybe you'll only have to do it twice. if you skipped even one thing in this procedure it will not work right.

SHEESaBEAST Posted July 12, 2005 Author Report Posted July 12, 2005 thanks for the info, unfortunatly i got the same thing fron trinity yesterday in a fax, but thanks anyway, also, they told me to use permatex motoseal 1 or 2 or the 3 bond crap, Quote
