Mention the forum... I am working on a forum discount. They just need to see the traffic.

If they don't have it they will get it for us... As per Gill. (parts)  Gill tells me he can get any parts we need. Super cool store/guy.

OOOps! Hope Kenho checks back before ordering. I just ordered some last week for a cvk carb, and the girl said they were 4, and I corrected her. That 4 stuck in my mind, and I second guessed myself off the Island.

Dellorto "small" (5mm thread) jets have a slightly different thread pitch compared to the Keihin 5mm ones.

They do fit somehow, but there's a risk of twisting the head off or cracking the needle jet because of the increased resistance, so proceed with care....

_If_ (!) your needle jet survives the first few jet changes, it's adapted enough to keep using those Dellorto jets, just don't go back to Keihin type because that would stretch it the other way again, increasing the risk of failure...

..yup, i've used delorto m5 jets before...all i could find local, and the ones i got had a longer head on them..

...i dremelled the head down closer to oem length..

..use some spit or other lubrication when threading jet in, if you go that route...

Sounds too risky, although I've had great luck at getting things to fit with a little spit in the past.
