Paging the carb wizards......

[terry1013]

Alright I've read through the posts for the last week, read all the how to's and still have a problem here.
Rejetted per the formula given 125/40/1 3 turns. Synched the carbs. adjusted the air/ fuel mix screws per instructions.  
Problem.....
It runs like a raped ape till I hit 5th gear then it bogs badly in 5th and 6th. I've narrowed it down to the 1/2 to 3/4 throttle range. I can twist past this point to wot and it does not bog as bad as though its trying, twist back into the bad range and its like there is a switch closing the fuel lines. Keeps running but really bogging. I've installed a clear inline filter and it remains full of gas when it is acting up in this range.
Other noticable difference after rejet. It starts hard, cannot touch the choke. Can start it easily if I turn the idle screw in about 15 turns it will start ok then I wait till the idle picks up to 3k, adjust it down, wait, 3k, adjust it down...... It restarts great when warm. My suspicion is the needles, can see nothing wrong there, any suggestions?
I've checked and rechecked the float levels and did replace 1 float seat that would not close. All seems well in this are right at the gasket levels.
By the way, fish aquarium air tubing works great to check float levels..
Love this forum and enjoy the info.

what happens when you run on prime

[terry1013]

It has no effect whatsoever
Still bogs.

[terry1013]

I'll also mention when its bogging and I roll the thottle back abouyt 1/4 it lurches and revs, gets to bucking when at the edge of the 1/2 to 3/4 postion.

stock filter and exhaust? stock jetting is 122.5 if im not mistaken. so 125 is still in stock parts range. if your running differnt airfilter then think it needs to be bumped to 130, 140 an 1 washer with slipon, and 145-150ish with 2 washers for aftermarket filter and full exhaust system.  belive thats what Srinath claimed

OK my first guess is ... air filter is dirty. Take it and slosh around in gas ... dry and re install. If you did that already ... next question will be ...
OK when it bogs does it seem to start sounding dry and like hissing ... that means slides are comming up too fast. I'd like more symptoms and specifics.
Cool.

Thanks for the replies so far guys... I have stock air filter and exhaust. Thinking bad air flow, I took the filter out to check the response and its the same. Should run with this configuration of jets and settings but its got the dead spot.

[terry1013]

When it bogs the only sound i"m hearings is the baooooooooo. No specific hissing noises.

[terry1013]

It bucks like crazy as though its trying.

in that case, is the restrictor (ring around air filter) on?

[terry1013]

No restrictor ring.

OK real jetting issues come up in 5th and 6th only so dont worry ...
OK try this ... open throttle fully in 5th and 6th from 1/2 to 3/4 ... see what it does.
Then open fast and see if it bogs ... fast bogging, slow not bogging = slide comming up too fast. How did it run before you touched it ...
Cool.

It did not run before I touched it. Tank was full of rust and I've cleaned and cleaned. Both carbs varnished VERY bad. As I took the carbs apart wanted to go ahead and rejet after reading much of this forum.
As I ease into 5th,  initially, its fine. Then it begins to buck. When I try to accelerate though the bucking it bogs bad till I'm very near wot. In the meantime if I ease into 5th and it starts bucking I can back off of the throttle to 1/4 and it picks back up. Very disturbing, takes off like a bat outta hell till it reaches that point again and bucks and bogs.

Gonna ride down the road, shall return.....

Ok I had a friend that had an old GSXR 750 ... his bike would bog and nearly die as he opened the throttle, and as he closed the throttle in disappointment ... the thing would wheelie ... The triple Hit him in the temple one time ... floats were too high ... You sure you're are fine ...
Cool.

Cold today, learning the charcteristics of the bike. About 6 turns in on the idle screw, no choke fires right up.  
After warm up, good country road here. Down 1 mile & back. First pass seems almost normal. little bucking in 5th accelerate through to wot & it picks up slowly. 6th gear better but same tendency to bog. When I flick to wot from 1/2 and 3/4 position it just goes to the wot slowly picking up speed mode. It seems to get worse as the bike gets warmer. fast flick to wot & slow flick no difference. It feels as though theres a dead spot from 1/2 to 3/4 & its bucking while in that zone.
Slow street right in front of the house on way back saw at 30mph get up to 6th gear & it's kinda backfiring sputter when I try to goose it in 6th while going that speed.

[terry1013]

I did replace the plugs.

[terry1013]

Floats have been checked , checked, rechecked and double checked.....
Wearing the phillips head off the drain screw..
I can run this thing all over the place through 4th gear, no problems whatsoever, when I hit 5th the show starts....

[terry1013]

Also took carbs apart 3 times and double checked the 14 mm heigth. All ok and level check right at the gasket, always.
It don't wheelie, when I back out of the throttle but it does lunge really well, again, very disturbing feeling.

I was thinking the retaining washer is underneath the needle circlip, allowing the needle to 'float'.

Getting more specific: what rpm in 5th gear does it begin to bog?
What rpm in 6th?
What about the same rpm in 4th?

Do the floats float?
