after replacing my speed demon 850 for a race demon 750, i seemed to get more power. when the swap was complete, we had jeted the new 750 #73 in primary and secondary. a power valve also in primary and secondary. it had way more power than the 850( jets #85 #93). but, with the new carb and smaller jets it seemed to run a bit hotter. i could really feel it in the foot box. the pipes were hotter too. seemed to be running great otherwise, but the heat concerned me.
so, i put new jets in the primary #75, and #76 in secondarys. i left both power valves. i havnt been able to really test it today because it is over 100 degrees here. i'll try it tonight. i did take it for a short drive, and i think the engine cooled off a bit. the power seemed to be there too, but didn't drive it long enough to decide.
anyone else have the same set up as mine?
