15mm Bing on derbi flat reed

Gonna work?

Reeds are thirsty (I hear) even at a 88 jet with the air filter 90% taped up if still runs hot as fuck on top could definitely go up 5-10 jet sizes

Is the avenue worth pursuing or is a bigger carb needed? Bone stock btw, I have a performance pipe on the way though

Do you have an air leak?

Not that I can tell from spraying the joints with carb cleaner.

Going to to a ghetto pressure test tomorrow and see if the seals are ok, even though I just put them in

Do you have a Dellorto?

Re: 15mm Bing on derbi flat reed

Nah, bing and a pipe is a solid combo. You've got air leaks.

I will 100% confirm this.

I ran a 15 Bing/Gilardoni 50cc/Zen and the bike was SO nice. Solid 45 mph on the flat with great take off.

As I recall, I believe I was running a 90 or 92 in there.

Yeah I have a 12.12 and 15.15

The problem is I don't have a good range of dell jets but I have a lot of bings jets

I can watch it climb pretty fast from 300+ at WOT I back off at 350 and it tops to 370 then cools off

Checking for air leaks again today.

Decomp feels like it seals pretty good

What pipe do you have? I have a new zen 65 id sell

Stock pipe, but I have a Puch treat pipe hacked for derbi on the way

I hit the head / head gasket with some 1200 grit on glass and it seemed to mostly clear up with issue, but it's still lean, better but lean.

370° is just barely on the high side of normal operating temperature. if you have points, set the gap accurately with feeler gauges and then retard the timing a little.

If you're really worried about it I would check again for air leaks, maybe take off your top end and intake, clean all the mating surfaces real well, make new gaskets, and seal it all back up. Then I would take off the temp gauge so that you don't spend all your time staring at it.
