Hi Guys,
Sorry for such a late post. It took me awhile to clear my mind and find my carb jetting records.
My F1 has big valves 42 IN/39EX, NCR7 cams, flowed heads and compression 11.8:1 My carbs are TM41 and have worked great for 20 years with no problems ( except hard to twist with my weak arms!)
Street setup with GiaCaMoto baffled exhaust and UNI foam air filters:
Main jets = 230
Needle clip = 3rd from bottom
Pilot jets = 40
Needles = 6FJ40
Race setup with open megaphone exhaust and no air filters:
Main jets = 250
Needle clip = 2nd from bottom
Pilot jets = 35
Needles = 6FJ40 (same as street)
Hope this helps but might be too late.
Rich
