Racing
34mm
my 1981 atc250r went 62 mph with a tired motor and got there faster than my 400ex
very respectfully
apparently the 85 and 86 diameter is 35mm(same as the 85 tri-z 250), earlier years are smaller diameter.
What does rated R mean
what does MLLH&R mean??
Direct crossover from Champion is a NGK B9ES or can also use a resistor plug BR9ES
The 85 & up may fit with some mods. Look at the bolt up for both bikes
You r means You are or your
because people r mean because people r mean because people r mean because people r mean because people r mean because people r mean because they need extra time at the end of school for sports so they dont go so late
a 1981 model bored .60 over with a 36tooth rear sproket and 18in tiers will do approx 68 to 73 mph depending on the porting
R stands for the resistance.
