Hello-I am rebuilding a '79 CR250. I am going to try and use the OEM Keihin carb. So far I have learned that there are no new parts available. Can anyone confirm this and if so offer a suggestion on cleaning and opening clogged jets. Thanks. Mike S. in CT.

The '79 CR250 carb uses 99101-357-xxx0 main & N424-24-0xx pilot jets, which are available from jetsrus.com, eBay, etc.

The N424- number is Keihin. I've never seen the 99101- (Honda p/n) main jets referred to any other way; I believe they were originally proprietary Honda jets.
