Picked up a 03 250 with 2100 on the clock. Had been sitting for 5 years, needs gas tank cleaned, carbs cleaned, chain, tires, and fluids flushed as well as some much needed tlc.
Carb is cleaned,
Oil an coolant changed,
Used "the works" in the tank and it looks great,
Hooked up compression test and added a little oil to each cylinder. Got 155 dead on each cylinder before the battery started reducing output. What's ideal compression numbers? I've heard 130's, I've also heard 139-219. Pistons look like they're in good shape and OEM spark plugs look like they've had little use.
