  1. I ended up swapping the 38mm airstriker, still bogged on the low end and was very pipey...either it was off or on, rode it all afternoon one day. Afterwards, i opened the exhaust valve covers, the valves were sticking, so I disassembled them, cleaned them, then reassembled the valves. Now the bike runs like a champ. I did not need to buy an airstriker to make the bike run properly, I got tunnel vision thinking it was a carbureation problem. I should have cleaned the valves before adjusting on the PJ/buying a new carb, but I learned the hard way... I hope someone else can use this as a learning experience.
  2. Good eye, ill get some new reeds and do another compression check. Then I'll put a top end in if the compression is still low.
  3. Here's some pictures of the reeds.
  4. I understand, the pilot controls the first quarter, the needle controls an eighth to past 1/2 throttle and main rolls in around a 1/2 and on... or something like that. Ok, update: I lied, I didn't have the stock pilot jet set up. I had a 52 pilot, on the 4th needle position. I just pulled the PJ, replaced the pilot with a 55, put the needle at the 3rd position and put it back on. Now it won't idle at all, but the bog seemed better.... what do you think? I'm leaning towards what you said about the exhaust valve. I did a compression check about a couple months ago and got 145psi. I will also check the reeds, but I was under the impression bad reeds would affect the power throughout the entire throttle range...
  5. @ninoSorry, as far as I know it is the stock needle, stock pilot and main jet (used the service manual to set everything back to factory specs). I started off with the needle clip in the middle/3rd position and it bogged. I dropped it to the 4th and 5th position, but it still bogged right off idle. I don't think it is an air leak, because once I open it up to about 1/2 throttle or more, it will pick the front end off the ground and go. That leads me to believe the the main jet is fine. Thanks for your advice.
  6. @nino I won't give up on the PJ just yet then. I'll go richer on the pilot jet one more time, and reset the needle clip to the mid point. Right now the I have the Needle clip at the bottom most position and it still bogs around 1/4 throttle or when I twist the throttle fast. I hate to start adjusting more than one thing at a time, but I think it might need to be richer on the bottom end. Also I followed the factory service manual to adjust the HPP valves to ensure they were not open during start up, so I believe it is carburetor related. I might try the governor rebuild and adjustment, but I'd like to take it one step at a time.
  7. Yeah, initially I thought the 36 was as well. I'll give the 38mm AS a go and report back
  8. thank you. I'm not sure exactly which direction to go, but I know I won't bore it to 144cc. The PJ bogs right off the low end, so I imagine it will be better than my current situation. Did yours tend to bog down low before the exhaust spacer? I will look into that as well.
  9. I was thinking about the 36mm, but I asked JD jetting, and this is what they told me.
  10. I know the pwk carb has a different slide. The first picture is the PWK slide, and the second, PJ. As far as the other internals they're probably different too.
  11. awesome, I'll look into that set up.
  12. The PJ carb is mediocre and has a mind of its own. It has some funky tendencies and only runs decent 1/2 throttle or more. #1 problem being the idle speed is hooked to the choke circuit (It will idle fine for 5 minutes, then slowly bog down), I have tried to go richer one pilot jet size, but then becomes too rich to kick-off. So, is it possible to swap from a 34mm keihin pj to a keihin 38mm PWK airstriker? I've read a bunch about 2000+ cr125's making the swap, but what are the limitations and challenges with the 99 PWK airstriker swap? Thanks, Chad
