Model 97 main jet

[tboone]

Greetings

I've noticed in the carburetor schematics for the SC, that the standard main jet is listed as a 350 with the spares as 410 and 420. Is this correct, or should the standard jet be larger or the spares be smaller? In all the other schematics the jets are closer numerically.
Just curious...….Thanks

Depends on the tuner and all the factors. no concrete absolute rule for jet size so many factors. I liked a full range of jets myself. ------- Clarence

My copy of the Super Combat (97) Owner's Manual lists the 410 as standard - with 420 and 350 as spares. I have NO explanation as to why the 350 is listed.

Thanks for the info. It helps to explain the problem I've had jetting my 03 engine and new pre jetted 32mm carb. It refuses to rev out past mid rpms.The carb came with a 350 main and 340 and 360 for spares.
Net larger jets are on their way.

Always remember . . . find "rich", then work to lean it out to "just right". Going the other way can fry a top end before you get through jetting.

Klemm covers it so well in my opinion. (Klemm vintage .com) or (Mikuni carburetor tuning for vintage) I think it is what we have been trying to tell everyone. --------------Clarence
