Talking Jetting

     

After reading this thread all I can say is with all of your help my 78 TS185 runs like a champ! It ran good and now it runs even better. Marking the throttle grip and following the instructions was easy and painless. Thank all of you!

This thread is excellent but I've got to say I do get a bit confused with all "boowang, gulp, and other" type descriptions. I do know the blubbering is rich and the surging or loping is lean. I am afraid that my bike is running too lean.

Let me start at the beginning. I just bought this bike back (I owned it 3 years ago) and when I first got it back it ran good but if you were not rapping on the throttle the motor was on the way down to die, which I thought might be too rich.. SO, we adjusted the idle by the air screw turning out. There for a while the motor was running wayy too lean because it would be surging or loping when I was not on the gas. A good mechanic buddy of mine started turning on the air screw until that loping went away. Right now my bike starts first or second kick with choke on and it idles amazing, almost too perfect. I know these 2 strokes aren't supposed to idle perfect right? Like I can just sit there and let it idle without rapping on it. So it runs amazing, power is there and all that but I've found myself not even realizing I'm already in 5th gear because it feels like all of the power is there too soon like as if I'm topping out way before I should. These mechanic buddys have said alot of different things but I really fear that it's too lean and when I'm pinned in 5th it's gonna seize. I want to get it right. When I used to own this bike I just remember it seemed like I could top out alot higher of a speed and still have power to the point I couldn't ever top the bike out hardly. Now the power is great but it's just there too soon and the bike is all topped out too quick seeming. I could be wrong though but let me know what yall think! I'm about to go down and figure out how many turns out my air screw is set...I know the manual says 2 turns out for sure. BRB but lemme know what ya think!

Holy crap fellas I am only 1/8th of a turn counter clockwise from closed on my air screw!! This means I need a step richer pilot jet correct?

Default Bogging

I have a 96 cr125. it idles fine and runs perfect (for the most part). but when coming off of idles it bogs pretty bad.. i have to give it a couple quick twistts to get it up in the rpms. Ive done the chop tests and been reading alot on jetting.. any comments would help.. im wondering if it could be something else like stuck power valves or something..:

you can see the power valves working by just taking off a cover and reving it a little, that way you can see if they are going closed. the chop wont tell you much if anything about your low end.

lowering it raises the needle, and that makes the range from roughly 1/4 throttle up start to get richer
