No Idea

how hot is the rectifier supposed to get.
Had the bike going for 10 minutes and its fairly warm.

Also checked pick up coils. Both are in spec.

 

It's ok for it to get warm.

 

What I'm stumpped on is yea it starts hard. But whenI warm it uo I can rev it up smooth. Sometimes it drops down below 1 grand. Other then that it won't bog down until I sit on it and try to take off in first .

 

Bog under load? Possibly fuel related?

Have you checked the fuel tank/petcock for proper vacuum and flow? Assuming its got the vacuum operated petcock. Could always plug in a hand-held vacuum pump into the petcock vacuum and pull some negative pressure on it and see if it will pee into a cup. Probably 5min worth of time. Additionally, all of that rubber vacuum and fuel hose is super inexpensive and worth replacing as well.

My TTR230 has a petcock with plastic pre-filters, rather, screens. Upon replacing the original it had degraded to a point of collapsing in on itself and was partially ingested into the brass petcock. It doesn't take much fuel to idle/briefly rev up a 230 but that might not be the case on a 750 and could be worth a look.

Good luck to you sir. Don't give up on it!

 

Update**

Checked for leaks again with some carb cleaner . Still idels perfect..took it for a ride up the road. Wouldn't open up all the way.
I did take my plugs out though.and this is what they look like.
Is it behaving this way cause I'm getting to much gas?

What should my next step be .

 

It's because you're missing a plug

 

Its there just didnt get it in the pic

 

All same color

 

That was a joke…

 

I'm curious… Remove your air filter element itself. Then go for a ride, see if there's any change in performance

 

When the carbs were off did the throttle slides do a nice clunk test? (Is that the right nomenclature?)

 

Yes clunk test was good .All even across the rack.

 

Ill give that a try tomorrow . what would it mean if the performance would be better .Or same .

 

Plugs say you're running rich... too much fuel or not enough air... no filter = air increase.

 

I did read that this could be from a lean setting to. But I'm just reading stuff lol

 

Black plugs = Rich
Tan Plugs = Just right
White / Eroded Plugs = Lean

Correct

 

Tried this today works alittle better with air filter out. Takes off better but hesitates on pick up while giving it more gas. Engine sounds deeper like overloaded around 4g and up.
Tried outting filter in turned pilot out more but still the same .

 

Maybe I have to much gas in my bowls could that be my floats are making me rich?

 

Absolutely, I posted this in another thread for a 550 that was acting like yours when hot:

" This is exactly what my bike was doing when I bought it and was a result of the carb bowls overflowing. Seemed find when cold (Wanted rich) and got crappy when hot. My commute is 30 minutes and a few miles from home it would start acting up. Turns out it was also masking throttle shaft leaks as when I got the levels close to correct, the bike rpms would start running away when you take the choke off...

That's when I sent the rack to hogfiddles . Been ok for about 1K miles now...."
