bones Posted August 24, 2006 Author Report Share Posted August 24, 2006 The stock coolant bottle location traps air/coolant in the line....it is possible this is what you're seeing. Check the coolant level in your radiator.... If it's fine...you should be ok... If not....you might have a bad water pump.. I'll give it a looksie... that would suck if its a bad water pump, the thing is brand new! Just got it in June! Quote Link to comment Share on other sites More sharing options...
bones Posted August 24, 2006 Author Report Share Posted August 24, 2006 Checked radiator, it was full. Plugs look good. Moved needle clips up one notch toward blunt end, seems to have gotten the bottom end of each gear a little more snappy. I still have stock pilots, do you think I need to up those any?

jbooker82 Posted August 24, 2006 Report Share Posted August 24, 2006 Shouldnt the plugs have a defined line like these? Or am i just lean? Quote Link to comment Share on other sites More sharing options...
dajogejr Posted August 24, 2006 Report Share Posted August 24, 2006 he didn't exactly get a clean cut on those plugs. Who knows if the blade or shell smeared the mark a little... I think you were just a little more careful chopping your plugs.... Quote Link to comment Share on other sites More sharing options...
bones Posted August 24, 2006 Author Report Share Posted August 24, 2006 I think you were just a little more careful chopping your plugs.... Im not sure.. I was pretty careful chopping them, and even before the chop i didn't have a ring like that. I too was wondering why mine were not as defined like others.... oh well. On another note, the right side pipe is actually touching my radiator hose, so that may be contributing to more coolant overflowing... gotta try and move it or get some kind of heatshield there.

dajogejr Posted August 24, 2006 Report Share Posted August 24, 2006 Flip the lower hose around. That plastic springy looking shield is enough....then, before you tighten the lower clamp down, twist the hose on the inlet neck to where you have a small air gap between the pipe and the hose. You'll be fine.... Honestly, you're plugs look fine.... Quote Link to comment Share on other sites More sharing options...

I appreciate all the feedback by the way.. Quote Link to comment Share on other sites More sharing options...

I appreciate all the feedback by the way.. Kinda... flip that same hose 180 degrees...so the plastic is at the bottom. Then, twist it a bit before you tighten it down for a little extra clearance.

bones Posted August 31, 2006 Author Report Share Posted August 31, 2006 Question about the coolant tank under the seat. Yamaha states it is a "over flow tank". If that is the case, why does the coolant spew out of a overflow hose up under the radiator and not fill the tank?? Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted September 1, 2006 Report Share Posted September 1, 2006 (edited) Question about the coolant tank under the seat. Yamaha states it is a "over flow tank". If that is the case, why does the coolant spew out of a overflow hose up under the radiator and not fill the tank?? There is two hoses. The one that hooks to the bottom of the over flow go up to the radiator cap nipple. The top hose on the over flow tank is a vent hose that is routed up to the front of the frame. Mine hangs down a little around the the radiator. Your over flow tank is probably a little over full. Or a little bounces around the tank, trapping a little in the hose, and when the radiator lets off a little pressure it blows a little out of the vent tube. It is no biggie. There should be a back hose just haning some where in up front. Look and see if that is were it is coming out of. josh Edited September 1, 2006 by jbooker82 Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 1, 2006 Report Share Posted September 1, 2006 Just to be clear...that is not a recycling system. It will NOT suck coolant back into the radiator...like a car. It only blows over into there.... I relocated mine to the front of the frame so air/coolant doesn't get trapped in the line. However, I'm one step away from removing it... My old CRs never needed/had an overflow bottle.... Quote Link to comment Share on other sites More sharing options...
bones Posted September 2, 2006 Author Report Share Posted September 2, 2006 ... It will NOT suck coolant back into the radiator...like a car. It only blows over into there.... Weird. Not doubting you but that brings up another question - why does the reservoir have "Full" and "Low" markings on? Technically speaking - it could be totally emtpy and the radiator could be totally full - so by reading the tank, it shoudl be low?? Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 2, 2006 Report Share Posted September 2, 2006 The stock design traps coolant...period. I've moved mine to the front, beat the bejezus out of it...and the level in the overflow bottle hasn't moved. And I check the water in the radiator before each day of riding...it hasn't moved.

Ducman Posted September 5, 2006 Report Share Posted September 5, 2006 Bones you should be fine with a 280 main with the air box lid on and snorkel removed, probably a hair rich. The aftermarket foam filter will flow the same as stock and jetting wont change unless you open the air box lid. You might benefit on you off idle throttle response with a 27.5 pilot. On your plug chops you are looking for a 2mm tall band on the base of the porcelin. Your band looks at least 2mm but a bit light because you probably didn't have it WOT for quite long enough to get a solid band. I used to have to do a wot run to the top of 6th and immediately turn around and do it again because I could only hold it WOT for a second or two in 6th. You should notice that your banshee will spit fluid a lot less often after it does it a couple times and only due it when it is truely overheated or you stop at the top of a big hill climb and dont let any fluid circulate to cool it off. Banshee's are like those sharks that will die if they quite swimming and moving water through there gills, you got to keep a banshee moving forward pretty regularly to keep air flowing throught the radiator so it will stay cool. Engine ice coolant and a billet impeller will help alot too. Quote Link to comment Share on other sites More sharing options...
