Does anyone have a part number and/or size for the output shaft seal on the engine, the seal behind the front spocket? The UK based sites don't like giving the Yamaha part number. I'm in Brazil now, where the part is both hard to get and ridiculously expensive (80usd). I have close ties to the US where this bike was never imported, can anyone confirm that the part is the same as a 660 Raptor quad, part number 93102-35368-00, 35mm x 52 x 8?

Thank you all very much!
