Engine coolant is leaking into the gear oil on our 02 Suzuki RM85. I know I have read posts about this issue before, just can't remember exactly which seals and/or bearings to replace. I have access to the parts microfische, so part numbers would be appreciated. Thanks.

Had the same problem. Change the stock water pump and seal. Use a boyseen model pump and stock seals.

Definitely go with the Boyensen water pump. It's a solid one piece unit. The stock propellar will separate from the shaft and ruin the seal. The stock seal and bearing hold up well. Good idea to keep an xtra seal and set of bearings in the spare parts box. They had a tendency to go out while your at the track.
