jst854 Posted June 4, 2022 Author Report Posted June 4, 2022 I threw the stock carbs back on and it runs great. I got the needles to hold on the 28 pwks, I also put the leanest jets I had in it, 135 mains and 40 pilots, no real change. There has to be something that fell out or is off with the pwks. They are my first set of Keihin carbs. Is there anything stupid, kind of like the choke tube on stock carbs that could be doing this. The only thing I saw on the parts diagram, https://images.app.goo.gl/gehY7xU8U5T7cBsH8 for the carbs that I am not sure about is number 34. When I take out 35 needle jet holder there is nothing that comes out with it. Is there supposed to be something there? Sent from my ONEPLUS A6003 using Tapatalk Quote

jst854 Posted June 4, 2022 Author Report Posted June 4, 2022 I did. I honestly can't tell. It has the genuine hoses and number etched in the side. Watched a bunch of videos on real vs fake and the only thing mine doesn't have is the quality control marking on parts of the carbsSent from my ONEPLUS A6003 using Tapatalk Quote
375hp banshees Posted June 4, 2022 Report Posted June 4, 2022 iirc, you can see 34, through the air horn, did you see note about SDGAA?Sent from my SM-A505U using Tapatalk Quote
375hp banshees Posted June 4, 2022 Report Posted June 4, 2022 I think its a guide not really a jetSent from my SM-A505U using Tapatalk Quote
jst854 Posted June 4, 2022 Author Report Posted June 4, 2022 Yeah it is more of a guide, went to a local shop and they confirmed that piece is missing and would make it run a lot richer. Ordered those, will let you know if that fixes it it notSent from my ONEPLUS A6003 using Tapatalk Quote
375hp banshees Posted June 4, 2022 Report Posted June 4, 2022 Put og jets back in & hopefully the og problem was fixed, with the 1st cleaning.Sent from my SM-A505U using Tapatalk Quote
jst854 Posted June 4, 2022 Author Report Posted June 4, 2022 I believe it was. The original issue was lean and would only run on choke. Something must have been clogged and while cleaning it lost those partsSent from my ONEPLUS A6003 using Tapatalk Quote
RagunCajun Posted June 4, 2022 Report Posted June 4, 2022 Many years ago, my yz250 would only run well on choke. The pilot jet had a tiny rock or whatever in it. Quote
