RIN-NIN-NIN-Nin-Nin-nin-nin-nin-nin-nin that looks like a nice example of a real fun bike, good score.
Had a rd250 in college, be sure to put oil in the oil tank, filler/2-stroke oil tank's on the left side there, I smoked my rd250 and learned about 2-stroke oil at *exactly* the same time. Note, when the guy told me 'make sure you put oil in it' I checked the level when I got home, the oil filler was *right next to the kickstarter on the crankcase* just where I expected to find it, after all, thats where you put in fresh oil on my cb400f and kz1000 -- right side rear part of the engine. I thought 'strange, there's plenty of oil in here, I wonder what he meant by 'fill it with oil' it looks fine to me.'
I pulled the heads after the engine puked, which was very easy, just 4 bolts and lift up, no cams/chain/valves etc. the piston on the right side was smoked clean through and the cylinder walls were scored beyond repair short of a re-bore. Gave the bike away, I was broke in college could not afford bore/rings/new pistons besides the local yamaha shop said 'your bike's too old we dont work on them anymore.'
While that sucker ran though it didnt feel like no 250 it was quicker than my cb400f. Would pop a wheelie pretty easy too.
