sup guys i just bought a used 95, 900rr and it has about 11000 miles ive been riding it the past couple of days and it seems that if i stay below 50 im fine but if i hit around 70-80 it starts leaking atni-freeze. does anybody know what it could be im new to riding. i can't really see exactly where its leaking.. thanks for the help i appreciate it.

 

i wouldn't be so much worried about the speed... does the leak seem to run in sync with the rpm's, if you run it hard in first and second, will it start to leak???

 

yea thats how it seems. when i hit it hard through any gear

 

yea mang...see...when you gun it hard and stuff, the motor revs faster, turning the oil pump faster which turns the water pump faster. so there's like more pressure with increase heat too. if the coolant is warm it'll likely leak too cause it expands.
you gots to find out where it's coming from.

 

you'll have to get an idea of the location like tahoe said, you've probably got a gasket/seal that is leaking once the pressure gets high, hence it will leak more with higher rpms. i don't really know where to tell you to start. i'd clean the engine real good, take it out for a ride (not to long or to hard) then when you come back get down there on the ground and do some investigating.

 

Does it leak when you have it (N)? You might want try and take off the plastic, run it in high rpm's at a stand still. If it only leaks when the engine is under a load you might want to use a dyno or have a friend follow you and see if he can see where it is coming from. If you do not have that option there is a product that uses a uv light to identify leaks (Basically a UV dye.). Good luck, I hope it is not the radiator or anything serious.

 

my f2 was leaking antifreeze, traced it to a hose clamp, tightend it up no more leak, hope yours is that simple

 

ya if you let it run just sittint there for a while it will pressurize and leak out. that is the redneck way of doing it or you could get a radiator pump and pumb it up to like 15 pounds and it will squirt out. also you could take all the farings off and look for where there are white spots the spots show that there was coolant and go from there good luck

 

thanks all i ended up taking it to the shop well at least i know it will get done the right way i don't want to mess anything up...
