Dellorto jet number? E2.5

Wesley Burson /

My dellorto jet says kw e2.5 or something like that. I'm running all stock but the pipe is from a tomos corlibi. Btw it's an a3 bullet. Thanks!

If you're going to post a photo like that use the macro setting on your camera.

I did a zoom and enhance. I think I made it clearer for you.

That's would be way big no?

Re: Dellorto jet number? E2.5

Use your wire gage drills, tang side.#67 drill is about a#81 dell jet.

Re: Dellorto jet number? E2.5

What about 52.5?

the hole size is 0.025" so would that equal a jet size #61? and with the motor being stock other than the pipe being from a tomos colibri. is the jetting too low? it has an over heating issues with loss of power after WOT? thanks!

Re: Dellorto jet number? E2.5

The stock jet for a A3 with the dellorto sha is #51. On the A35's it's #53. #61 would be enough for an expansion chamber so it would be enough for a stock colibri pipe.

so if the jet is right what causes the over heating?

What is the difference between that stock pipe and a regular Tomos pipe ?

just thought about it. could a loose exhaust be a cause of air leak and then makes it run lean, so it over heats? i think i found out my issues whist feeling like a proper idiot!

Re: Dellorto jet number? E2.5

Timing could make it overheat if it off.

Re: Dellorto jet number? E2.5

exhaust leaks can cause scratcheing and lean, so i guess hot. how do i know? why the hell did every motor i run have them scratches up and down exhaust port, right over it, under it, until i ran a good exhaust gasket and kept it sealed.
