[Norrie Bodge]

hi
is anyone using a Mikuni TMX-30 carb on a TS1-225
i wanna ballpark starter jetting please...
its gonna be fitted onto Indian casings with a 58 x 110 crank, firing throu an Early Taffspeed exhaust or a JL-3?
whichever performs best??

thanks

main = 280
Power jet = 80
Pilot/Idol = 35
Slide = 4.0
Needle = 5EL68

Hi
Your exhaust will contribute to what jets you fit,anyway i am running a TS1 231 with a MikuniTMX 30 pj ,BGM box,NO FILTER,jets as follows,

ATOM 622 0-2
MAIN 260
IDLE 22.5
POWER 60
NEEDLE 5EL68

Runs well 80 MPH, good starting ,good tickover

Have you run it with this jetting? Looks like a decent starting point to me.

I run 250 main, 60 power jet and 25 pilot in my Imola with Franspeed Race, goes well.

Carb clears the panel but no room for a filter.

the lad who i bought it off had it on his RB20 so you maybe right it could be a good starter setup? we`ll see?

Morning, Rennie.
What kind of mileage are you using the 30? thinking off future project, my TS1 with a 35 is fast as but shocking on fuel but good fun.
Cheers Shane.
