Scooterotica

I am trying to set up a mikuni TM24 on a 186 mugello with an af rayspeed 42mm zorst.... (remote filter)

started off with a 175 main and 20 pilot ... messed about with various other combinations, but that was the best of a bad lot... 4 strokes until the main jet kicks in, then it flies!

any suggestions as to jetting or solving the problem?

thanks

david

What needle are you running?

have you seen this

It will get you there or thereabouts

It's fitted with a 5N14...... that's what most seem to run well with.

The alternative is a 4DH7. I'll see if I can find out if that's leaner or richer.

The 4dh7 is leaner.

The needle jet is changable too. Fitted with Q-0 but either side of that are P-8 or Q-2.
How does it run without the ramair David?

it runs better, martin, but still struggling a bit on pilot....

i will check the choke is seating properly at the weekend and double check the timing....

is there anyone else you know that's bought one and running with a muggy??

Check the carb section on LCGB David, I'm sure there's a few on there if you scroll back through a few pages. I can only recall selling one other for a Muggy and I've not heard back from him. Forget what exhaust but I'm sure I'll just have quoted the 20 & 180 as starting points.

Try a 15 pilot if you've got one , and start at half turn out on mix screw, i'm running that pilot on a proper stage 4 200 with jl4 (race), Cheers Baz

Yes, they're popular on stg 4 200s and classic rapido 200s so I'd have though the jetting would be pretty close for both 186 muggys and Mild 200s, main jet appropriate to the exhaust.
