[QUOTE="badseed, post: 190136, member: 2846"] The forums are back up :banana: Quick update.... got the carb rebuild kit and I rebuilt the carb today... ( but I broke the cardinal rule....and made two changes at once)....I went down one size on the pilot jet and raised the clip one spot on the needle (went from stock 3rd middle clip position and raised it to the 2nd clip position)....The bike runs like a totally different bike....climbs hills now and it wouldn't start cold without using the choke :thumb: my air screw now works but it's not a very noticeable change when adjusting it..... It was ridden for about a hour tonight and "almost" no spooge out of the silencer :clap: ) My son loves it and says leave it how it is....but me (dad) am not done tuning it yet :ride:...... So, I'm going to pick your brains a bit more if that's ok.... It runs GREAT from idle through 6th gear "if" you stay on the throttle..... I found this (below) from some internet searching....would you agree with the below statements? ________________________________________________________________________________________ On a 2-stroke - You should be able to ride in 3rd gear, throttle BARELY cracked open, and it should cruise smoothly. If it sputters and crackles, the pilot is too rich. If it bogs, the pilot is too lean. (The bike runs smoothly).... ________________________________________________________________________________________ Needle Clip: On a 2-stroke - Riding in 3rd gear, with a warm engine and the throttle BARELY cracked open, roll the throttle to 1/2. If the bike sputters and crackles, and you feel like you have to keep rolling on the throttle to smooth it out, the needle is too rich. If, on the other hand, you get the dreaded 'buhhhhhhwaaaaa', the needle is too lean. (the bike gets the dreaded "buhhhhhwaaaa" so I'm thinking I should put the needle clip back to the stock 3rd position??? <-----that cardinal rule I broke making two changes at once). ________________________________________________________________________________________ Main jet: On a 2-stroke - Riding in 3rd, with the throttle BARELY cracked open and cruising along, whack the throttle wide open. If you end up with a set of handlebars impacting your nose, or you loop out, the main is perfect! If it crackles, smokes, and won't get 'on the pipe' quickly, then the main is too rich. If it gives a 'buuuuhhhhwwaaa' sound and feels like it's sucking for air, then the main is too lean. (the bike gives the "buuuuhhhwwaaa" should I go one size bigger on my main jet?) ________________________________________________________________________________________ again, from idle through 6th gear "if" you stay on the throttle it does run great!!! also.....The new packing I bought for the silencer...repacking the silencer without cleaning out the pipe is defeating the purpose? How would I clean the pipe to get all that spooge out that I'm sure is still sitting in the pipe? Or should I just leave it how it is and repack the silencer? ________________________________________________________________________________________ I'd like to thank everyone for getting me this far and I appreciate you letting me pick at your brains a bit more:hail: :hail: :hail: :thumb: [/QUOTE]
