For a 1987 250 Trail Boss the Dealer wanted $19 a piece for crank seals.
The crank seals are 30 x 44 x 7 & I paid $3.67 a piece.
The magneto cover seals are 40 x 62 x 7 and are $5.85 a piece.
This was at a bearing supply store.
Now I need to find a belt, dealer wants $80.

 

Just look at Ebay. They have the old 3211077 replacement belt as low as $37. Plus just Google this number and you can find em even cheaper. OPT

 

Thanks Tech, that's the belt I need.
I can't believe what a difference changing the crank seals made on this motor. I was blaming the carb, but the seals was the fault.
