ok its back together and running again

Uh-oh, there is prime potential that you had an air leak right at the spark plug. Someone on this thread suggested that an air leak may be causing your problems . . . looks like they could have been right. You now have another piece of evidence that a pressure test should be done to assure that DPO...

great info guys and i would agree this 2 stroke tuning is art form that i am trying to get better at the 200 main seems to foul plug to soon so i am considering going back to the 190 had nightmare tuesday after fouling plug. threads came out with plug.this sucks threads seemed loose from day one but...

Your comment about it not doing the same blubber at 1/2 throttle in any gear except 2nd probably comes from the fact that the engine is not really "pulling" at steady 1/2 throttle in 2nd (and you just won't leave it at half throttle in 1st - note that I wouldn't either). Anyway, jetting i...

2nd gear only clears right up unless you hold throttle in that place?? Not sure of your statement and what plug?--Clarence motors seems to have a little rich sputter (4 clycling ) just a little past half throttle and if you hold that throttle postion it want clear up but if you give more or less th...

ok after getting muffler/baffle with sound i wanted here is where i am on jets pilot 40 with screw 1 3/4 turns out main jet 190 needle on 2nd notch from top bike runs real well just a little rich sputter about 1/2- 3/4 throtle 2nd gear only clears right up unless you hold throttle in that place stra...

Since you are heavily inflicted with the DPO syndrome, is there and possibility you are trying to tune with an incorrect air screw? That would really make things fun. I dont think he swaped air screw but I guess I cant Be sure .it appears that he used reeds intake and carb off 03 wombat or road toad

while i am waiting on the mail man to bring my new selections of pilot jets i did as ed recomended with the 40 pilot jet, i started at 1 1/2 turns out and if i turn it inward motor slows down if i turn it out past 1 1/2 turns there is no real noticable change untill i hit 3 1/4 turns then you can he...

thanks ED you bring up some good points.i went ahead and ordered pilot jets 35,30,25 one of these has got to be in right range i dont think i have ever had this much issue getting bike jetted before. but with all the mixed up parts that dpo (in my case dead prevoius owner) slapped on this bike it su...

Bronco70, I recommend that you do a bit of a review on the procedures for tuning a Mikuni. One of the first things you will learn is that when you are searching for the correct pilot jet - the way you know that you have the correct one is that things will be "right" when it "tunes in...

i will check reeds again danny cooke looked at them and thought they were ok when i 1st got bike what you said about pilot jet being around 40-50 is where i get lost since i started with 45 pilot and it would run ok at 1 1/2 turns out and had dialed in on 190 main still seemed rich went down to 180 ...
