The 10th digit is the year of manufacture. f is 85, g is 86, h is 87 etc. So yours is an 87. It should have the 6 speed tranny as well.
What is stock adjustments on 86 lt250r
1985 Suzuki LT250R
20:1
Wiring diagram
about 70- 90 mph depending on if its ported or bored.
does it have spark fuel and copression, is the carb clogger, piston worn, or plug fouled?
you need a manual since you do not know how. If you do it incorrect you risk breaking some expensive parts ,buy a manual
1,350-1,450 rpm (Shaft driven 2 3/8 turns out) (chain driven 2 turns out)
nope, the 85-86 motor is angled, the 87-92 are not. and the cylinder mapping is different as well.
Stock it will top out at 70-73 mph. Bear in mind these are built for a track so it's not the top speed but the acceleration and handling
nope, sport quads from this era were race quads. reverse gears add extra weight and basically if it wasnt required and it didnt help you go faster they left it off.
Stage III Trinity racing motor in my 92 LT 250r w/ FMF pipes, 100 LL fuel Pro-design head, and lots more ran a true 70mph. This machine was built for the woods and had plenty of extra weight in skid plates.
