Hey all 78' Cb750k new to forum

[TOOLS1]

The dieing when the throttle is twisted very quickly has been a common problem with these bikes since new, but pods make it worse. When you are moving, it becomes a bog.

Ive noticed it while riding the bike out deff bogs if i crank it.

If i could find a stock setup I'll try to snatch it.

Hey man, you just need a stock airbox? I think I still have a couple if I haven't given them all away. I'll check and see what I got.

Well, i ordered #45 pilots and fresh clamps for my boots. The old ones were deff from the 70s. If that doesnt work i couldgladly use an airbox to make this thing better than what it is. I like the look of the stock box anyways

Hey Shiney, you have any extra air boxes?

All of the above! Synch the carbs is a must. Valve clearance can definitely cause backfiring. Low timing can cause a lack of revs. Cam chain is just a good idea and takes 2 minutes.

I'd do the valves and cam chain first. Then synch the carbs as the engine is warming. Once hot, you can rev it and check the timing.

Timing before carb sync. Carb sync is always the last thing to do when tuning an engine.
