As some may know, I have a somewhat modified 750. Js1 cam, BSA lifter and beehive springs, 40mm carb that we won't get into now, JoeHunt Mag, milled head RH1, 1 1/2" exhaust, blah blah blah.
My issue is when backing off the throttle a little when shifting or cruising a boulevard with little to no load while neither accelerating or de-accelerating, I get a bit of a crackling effect or a pipie kinda sound. It seems to say, "Hey, ass hole, give it some gas and lets get going here". Accelerating and at highway speed all is good.
My thinking is that
1. my cam is advanced 10 degrees to function
2. the big bore exhaust just isn't doing it for this setup.
So, for 1. perhaps a stepped cam key to bring it down to 8 degrees advanced.
and 2. Maybe a Viking 1 3/8" 2 into 1 might offer better back pressure for my fussy setup.
Or 3. this is the price I have to pay for my hot street 750.
For what it's worth I am neither lean nor rich throughout the entire range
What do you think?
