my brother just bought a '90 suzuki lt250r. it had been sitting for about three months before he got it. thing has compression from
H*** and darn near broke my ankle a few times(occasional kickback) before i decided to put on MX boots.we kicked it till we were
blue... and nothing.
as for what has been done to it.. i checked and replaced the plug-it was wet, but not fouled.
apparently its had a 2mm overboar done on it and a wisco piston put in, now with only about 3 hrs of ride time on it. and the
previous owner claims that is all that gave it the high compression. it seems to have been ported, which he also confirmed, but that was done before he bought it. he was running a 16:1 oil mix for break in, using suzuki brand pre-mix. it is running a 38 mm mikuni, 330 main, haven't checked the pilot yet. he claims to have had it tuned, jetted
properly at sea level(where i'm at), then went riding at 6000ft, and the only change he made was turning the air screw out to 2.5
turns to compensate.other mods to it that i know of are boyesen reeds, FMF gold pipe, answer spark arrester, and a K&N that
needs cleaning real bad.
any suggestions on what to do to get it started would be greatly appeciated. occasionally it will fire, but not run, sometimes violently backfiring.

are you using the gas that was in the tank when you bought it? If so try draining it out (thru the carb to clean it) and use some new gas. There could be some condensation from sitting so long. Just to make sure the tank is clear of water I'd pour a small amount in & drain it out also before filling it. I had a similar problem last month and it turned out to be water in the gas from the gas station.
