[QUOTE="sanstoetter, post: 1441966, member: 128616"] I'm in the process of rebuilding the engine on a new-to-me 93' KDX 200, and in the process I've found that it's running a Koso 34mm carb. (Pictures Below) **Let me know if there are anymore pictures that would be beneficial** Backstory: I bought the bike running, but with transmission issues (5th Gear on the input shaft is locked up). It started up easily, idled well, revved well, but I could not run under load or WOT. From what I could tell the previous owner did not realize it had transmission issues when he bought it non-running, and once he got it going he bailed. I believe he was the one who installed this carb, and never had a chance to actually ride it. Bike Specs: 1993 KDX 200 FMF Pipe/Silencer Boyeson Power Reeds Uni Cone Filter Wiseco 66mm Piston Questions: 1. Is there a way to identify the current size jets if they are not marked? 2. Do these jets look similar the the Keihin jets this carb is modeled after? 3. If the bike idled well with the current jetting will it suffice until the piston/rings are broken in? 4. Any suggestions on a base jetting to start with if I need to buy new jets? 5. Is this carb going to seriously hurt performance enough that it'd be worth a couple hundred to find a stock carb?
