These bikes run extremely hot compared to 2 strokes so its hard to tell if what your feeling is normal or not. However the water pump seal issue is a common one. I would replace the seals as well as the water pump shaft. I'd also pickup a temp gauge that way you can see exactly what temperature your bike is running at instead of relying on feel or the "dummy" light.

its aftermarket, esr and a few other companies make them. Checkout the tech quad shop or kb motorsports on here, they should both have them.

I also have a ? About the muffler its aluminum with 5tg501 with a forestry approved sticker that says summit on it summit make atv parts? The head has factory numbers with a blue ink stamp under it machine shop maybe its a pain in the ass to configure the slightly bigger aluminum airbox and battery box and mount the starter relay and clutch switch I was told the subframe has sum flex so I rubber mounted a few things

Do you have a car? You aren't that far from Buffalo or Erie, I'm sure there is a Yamaha dealer there without googling it

[jonnymonofrax]

Ya hour away not much in stock all back together new water pump gaskets and seals looks like I have more than 1 head gasket bad sign?

[06yfz]

more than one gasket or did the gasket come apart when you pulled the head?
