Guys, I've got a 1999 Honda Foreman 450S. It runs great, but smokes out the exhaust after startup until it warms up. I'm thinking the valve seals are leaking. I was wondering if there is a way to replace them without removing the head or if there's an oil additive that will recondition the rubber seals. Any advice?

Hey all, Thanks for having me in the forum. I just purchased my first ATV and am stoked to understand more about it.
The first stupid question will be, what is everyone's maintenance schedule? DO yo follow the recommended intervals or build one yourself based on the machine.
Thanks in advance.

The small waterline insert for the hose that goes from the water pump cover to the thermostat housing has corroded off. I only need the insert on top and behind the thermostat housing that the hose goes over and can't find just the insert. It looks like it may be pressed in. I've have been told the entire motor housing needs to be replaced. The pic with the red line indicates where the hose and insert would be and the insert looks like the pic of the water pump Any ideas would be really appreciated.

Just finished replacing water pump seals and impeller on my 97 Magnum 425 due to oil leak out of the weep hole. Haven't owned it very long and have only riden around the yard a couple times because I only recently got it. I installed a new bullet aluminum impeller and made sure the nut was tight and that thebimpeller was not spinning on the shaft. My oil leak is now fixed.
I filled the radiator and let it run. The motor seemed to be getting hot and the radiator fan never came on. Looking into the radiator its hard to tell if the coolant is circulating due to the vibration of the quad. Never looked down the radiator prior to pump rebuild so not sure how it compares now.
Think it could be a bad thermostat or air in the system? Is there a refill procedure? Any advise is appreciated!

I chased down the leak on my 97 Magnum 425. I have a nice leak coming from the water pump weep hole. I am being told the oil seal inside the pump needs to be replaced. Can anyone tell me what is involved in the repair. Can it be done without pulling the motor? Thank you!
