Dang just can't get it right

I'm running
Needle-B53e
Pilot-68s
Main-175
Air Screw-1.5 turns out

It seems to be lazy on the get up and go and when backing off she backfires, I'm running and FMF powerbomb system and motor is stock.

It had the lean serge with a 172 main and popping on WOT, 175 has stopped that and pulls better but now the idle will go up and down.

Any hepl would be great

Took for test ride and have checked the plug, plug colour says it is now spot on. I have also checked float level and found it to be way too high so I have now got it to 15mm from top of bowl which is alittle too much by 1mm. It is now harder to start and I can't seem to get the idle right?? Help please

Couldn´t get my hands on a 178 and used a 175 on the 4th position down from top.

Bike running stronger, wheely comes out every time...sound perfect but need further test drive.

Just noticed some increment on oil temperature but not sure if results from higher air temperature (summer is coming up), or any other reason.

In low rpm bike not so strong...not sure what to do.

Try do adjust air mix or move needle?

Guys, need some advice how to proceed.

I'll do some more tests to evaluate low to mid throttle performance, midrange and three-quarters to full throtle performance, and take some readings.

I'll remove spark plug and clear it to see any changes in spark plug to help reading engine lean/rich condition and be right back with some more data.

Don't you guys use to mess with your carbs?
