just wondering what you guys with 1100 cc engines are running for jetting.
mine has flatslides that are bored to 41.5mm with 480 mjets
thanks

I run the same jetting as you. I have the bored flat slides with KN filters. I run DD 1107 pipes with DD 1107 F5 cylinders. I have ran 2000 feet with no problems. Maybe a little rich for 660.

what elevation are you running at?and outside temps?
Im at 2500-3000 ft tems around +10---+40
I think mine is pig fat

Do you have any traction problems?
Thanks

I know that on one of Ron's 1100 motors that he did for someone, that guy is running 540 mains with bored flatslides. He said it is a touch rich with that main jet, but not bad. Ron ported an 1107 that started out as a D&D 1107 for me. It is going on my sled next week with bored flatslides. I am starting with 540 mains just to be safe too. If I end up with something other than that, I'll try to remember to post.
