[QUOTE="2-Strokes 4-ever, post: 891706, member: 58946"] Yes, it's the dial on left side/front of cylinder. Maybe someone else can clarify this since I'm too lazy to go and take my son's 125 apart. You can remove knob (two screws) and see how knob fits into spring. If I remember you tighten the tension 1 turn and line dial up with mark. If there's no tension on spring, the valve opens too soon and low end power is total dog. But keep in mind that there isn't much low end in that bike when adjusted properly either. Just get used to abusing the clutch. It's amazing how you can do little things to improve the low end of that bike too. I used to race it in H.S. and little tricks like adding 2-3 more exhaust washers into cylinder before pipe goes on will make it a little torquier...low end reeds help...advance the timing just slightly...And we took I think 8 thousanths off the base of the cylinder. Got these tips from Bill's Pipes back when they did a lot of work with Team Suzuki. Even still...get used to measuring the wear on your clutch plates often. Never had a bike that handled as sweet as that 125!!! But I've gotten lazy in my old age and prefer not having to ride so aggresively...(went 250) [/QUOTE]
