I own 2 of them, the first one went 3 gallons before I pulled the sleeve and had it pinched ($15).. It now has 6 gallons total and still running strong on the stock bearings.

The second one went 4 gallons before I got a deal on a speed sleeve and piston. Stock crank and bearings in it and it's still running strong with 4 gallons on the P/S and 8 on the crank and stock bearings.

I bought both of these 5 months apart from 2 different places. I don't get lucky ever in my life, that's just how it is for me. I might stumble on some nice deals sometimes but thats about it. I got the speed P/S brand new for $100 bones.. I think the $15 I spent on the one for what it's been through is just fine.
