GlHonda...
Heard...

Also last time I'm putting 87 octane gas in my Wing tank... no wonder why there's more and more no ethanol fuel pump around here...

87 octane is not contributing to the problem.

If you have a carburetor issue it is surely related to the rebuild kit you used. Do yourself a favor and start over. Run everything past us before you do/use it.

Did you pull the rack apart and soak, or do a sonic clean, on the individual carbs?

Why ain't we ridin'?

Sounds to me your slow jets are still partially plugged. Having to keep it choked as you described is often the first clue. With the choke on, will it increase RPM up to say 2500-3k and then allow you to take off the choke? If so, see my first comment. Good luck.

Hey John... the slow jets are brand new...
It's doing better since i followed the advice of a winger who told me to set up tbe pilot at 3 turns instead of the 1.3/4 per the book...
It's now idling without the choke... i still have problems going up in the rpm after 25% on the handle... just when the mainjet is taking over the slow jet from what I underdtood ...
So my 102 seems really too small...
I dug out the jets i Initially replaced and they are 105...
Im currently trying to unscrew them from the rest of their body... corrosion has sealed 3 of them...
I feel like I'm gonna be better off with buying some new 105 from jetsrus...

New source of stress... engine off I engaged the 1st gear and was able to move the rear wheel with my bare hands without efforts... whille engaging the 2nd gear I couldn't move the wheel as it should be ...
Does it mean my 1st gear is shot or did I forget something?

Are you sure you got it in 1st gear? They won't always go in gear easily with the engine stopped and not moving. If you have been riding it you would know if there was a problem.

With no God over the state, the state then becomes not the defender of liberty but the definer of liberty.

Hi Dave (damn I love your yellow wing)
Well the contact was on and I saw the Neutral light turning off...
So i believe the 1st gear was actually engaged...
I tried several times to be sure...
But no i didn't ride it ...

Bump the starter button with the kill switch off, just enough to turn the motor over a half turn, or so.

Or just spin the rear wheel while pushing down on the shifter. And make sure the shifter isn't hitting something.

Ok guys thanks...
Good news i could separate the old 105 jets head from the tube...
Cleaning them is a major PITA...
...WD40 bath
... vinegar bath
Using only carbon fiber and nylon rods to avoid any scratches...
Getting there

Latest update...

After cleaning the hell out of the old 105 jets i put them back in the carbs this morning...
Well result is exactly the same...
. Starts with the choke
. Takes forever to get in temp
. Idles without the choke
. But when i try to go over 1200 rpm the engine stalls

Any idea what to try next ?
Thanks
