I recently purchased a 2006 Baja Wilderness Trail 250cc from my friend which from what I gather the motor is a clone of a Yamaha Timberwolf / Beartracker, this is why I also posted in the Yamaha section, well after making a few minor adjustments to the unit it starts and runs really well, but, I just did an oil change and I found the pin in the oil drain plug hole, I just cannot figure out what this pin could be from, any ideas. The ATV still shifts and runs great....

 

looks alot like a shift fork guide, lol how they hell, maybe a big dowel pin...or piece off the shift shaft all i can think of.

 

Did you look at the parts break down of the shift rail assembly? Motorcycle Parts|ATV Parts|Honda|Kawasaki|Suzuki|Yamaha|Dealer|Wholesal e Discount Prices There are some small pins there.

 

Yer, I looked at the parts breakdown, but still not sure what part it could be, its only 20mm by 3mm, so i thought it could be a roller bearing rather than a shift fork or dowel pin, but it still starts and shifts fine!!!!, D`no, maybe it nothing or i`m waiting for it to break, well thats what i`m gonna do, wait for it to break then replace with a Yamaha engine..
