Been tuning the motor today, it was way off tune but running well after installing the LM-2 so thought I would share it with you guys!!  Grin



P.s. The cylinder temp is high because it is not connected, and the small oil leak was from a semi loose sump plug!  Roll Eyes

Greg its a Barry Grant Demon 650cfm carb, I have fitted Percy adjust a jets in it. At the weekend I was trying 74 primary and 83 secondary but it was way too lean, so I upped the jetting to 80 P and 86 S. Knocked 1.5 seconds off my time and the afr was reading 12:1 so I was happy apart from I adjusted the idle screws in which stopped it from running off power!!  Roll Eyes

Thanks Danny,

I managed a 12.3 @ 107mph, but it didnt feel right with the fuelling problem Huh So hopefully I will get it sorted soon and get into the 11s  Grin
