Air leak?
I installed the Murray’s Carbs kit on my 77’ CB750 and have been struggling for months to get it running right going back and for the on the phone with them. It’s rideable now but the current issue is this: I can’t go past 1/4 throttle below 5,500 rpm or the bike bogs severely. Cant even blip the the throttle to rev match. Keep in mind the bike ran fine stock and I have ridden it for 3 years so I don’t expect the issue to be unrelated to the carberation.
Here is a list of all the diagnostics I’ve done so far.
Check the ignition system (which I already refreshed)
Check timing and advance
Compression test
Valve clearance
Temp gun on headers
New gas in tank
Full battery voltage
Check carb boots for cracks
Replace boot clamps and tighten
They even sent me a whole new set so try and the bike behaved the same so I believe it is something on the bike itself.
Where else could I be getting a leak from??? Or does anyone have any ideas??
