#68 Delortto Jet swap

Considering this I used a tire tube to make me a oring for the carb cap. It tightens up nicley now and no longer loosens itself up. Studder problem is still there though. If I kill the petcock when it starts studdering the engine will run nicely. Im still thinkin its getting to much fuel. Considering a smaller jet, maybe a #65. Ill keep you guys posted on the outcome.

BTW the bike has been running great at times and running down cars running speeds of 40mph, passing a car at that rate is great.

Where can I mail order one of them jets?

Sorry if this is a stupid question, but is this a simple mod for my stock carb? Can I buy one of these jets and experience better performance, or will I need a different needle as well?

Just swapping the jet made a really big difference in the way the engine ran up top. I think a #65 with a lower clip positoin on the needle and itll run really great. With the #68 my bike runs over 40mph, but still experiences some top end studdering and missing which can be resolved by turning the petcock to the off position(limiting the amount fuel going in). The leads me to believe that while the #68 helps the engine to run better its still getting to much fuel. Though on some days its fine, others it runs crazy. Cheap parts means limited tuning.

Yes though the Dellorto 1486, jets fit rite in the china carbs.

Lower clip position? In other words, moving the clip down one from stock or up one, because I've already moved the clip up one from the stock position, it runs better than it did, but I can still see some room for improvement. The motor almost seems like it's hesitating near the top end..like it wants to go faster but can't. I notice the bike feeling like it ever so slightly slows down then immediately tries to go faster. Not sure if that describes the "bucking" sensation that some people notice.........

Bucking as in studdering, you are gettin to much fuel in there. Id try finding another jet to put in the carb. My #68 works good but not great. Pablo swears by his #65, which is what im waiting on to arrive in the mail.

Ok, so what I've described accurately points to too much fuel? Where do I get the #65 jet?

#65 jet with the needle clip on the 3rd slot runs great. No idle-WOT bogging and no missing on the upper rpm range. Running a consistent35-40mph.
