[QUOTE="joh9356, post: 897958, member: 60066"] While I am waiting for my CDI box, I have another question. Does anyone know what the original carb was on this bike? I have a PJ 38mm, but is that the original series? I spoke to Keihin USA and they told me since this carb was probably the original (they couldn't be for sure), and needed to be replaced. Reason: Keihin, being an excellent carb, has a problem. The jet needle seats in the carb housing itself, not a brass threaded seat like in Mikuni's and others. While this is not a problem right off, it will slowly wear out the seat of the carb housing causing mixture problems. The only way to fix this is by replacing the carburetor, which I find myself needing to do at this point. Now, back to my earlier question, the reason I need to know the original carb, is because I want to get a PWK series and I am undecided as to which I need. Being a 250cc, I want to go with the PWK 38, but the PWK 35 may be closer to the original. Can anyone please tell me which would suit me better? If you want the specs, they're at the first part of this thread. The PWK 38 is closer in dimensions to my existing PJ38, but my PJ38 is also a tight fit to the intake boots, causing me to think it had replaced the PJ 34/36 by someone earlier. Any help would be appreciated. Jim [/QUOTE]
