Yet another M750 bogging down with throttle

[pneumadeux]

Thanks very much for that. I absolutely know for certain that they are not clogged, because before rejuvenating them and getting them all spliced and sliced together, gently blowing by mouth allowed flow.

The air hose that connects to the carb from under the fuel house goes to a breather pod but doesn't have a filter. Does this serve the same purpose as the others?

Meanwhile, I still have a bike that when I opened up the throttle on the straight road leading to my house after yesterday's round trip around the block, it simply had absolutely no pull. What jets do I need to change? What adjustments do I need to make?

 Taking the factory pro instruction sheet literally that came with the kit, since the bike had such poor pulling power with the throttle opened up, going to install the next larger size main jet.

Stay tuned for details.

You're chasing your tail IMO.

There's no reason that a bike that was running OK would suddenly need a larger main jet just to rev.

Something is wrong, and you've missed it.

Have you tried a new set of plugs, or are you still running the ones you fouled and cleaned?

[pneumadeux]

Oh the little things...

Thank you for the simple encouragement to replace the plugs. They were fouled.

I did up the main to 145, adjusted idle, and tested her.

Omg.

New bike. Front end coming up throughout the range. No surging at idle even after 30 minutes of hard riding.  Will be testing her for 2k - full throttle snap later to make sure floats are nailed and no bogging.

Thanks for all the thinking.
