That's great care to share what you ended up with as regards jets , could be helpful for someone else in the future

Welcome looks sweet

I don't have the specifics info you're after , but I am thinking the different part numbers could possibly be for lower emissions/power restrictions as I remember an EU mandate thing that limited bikes power in the late 80s ,it led to manufacturers doing things like fitting carb tops that didn't allow the slide to open fully (kawasaki), welding washers in exhausts (Suzuki) , or moulding blockages in inlet rubbers (Yamaha).... Hope you get the information you're after but that is what sprung to mind

Nothing wrong with that ! Sounds great

Pictures are always good and information is always appreciated and as stuff becomes harder to find in good condition the ability to swap and interchange stuff is much needed

I think it's just that you can see the engine rather than it being hidden by the fairing lowers and the first bike is a black on black colour scheme whereas the second one the silver engine jumps out visually

Is it still on the original 20+ year old carb rubbers ? If so have you tried the spray of carb cleaner around them to check for air leaks either from the rubbers themselves or the o rings where they bolt to the head ? It's quite possible that pulling the carbs disturbed/split something ,that would cause your lean spot and when you pull the choke it richens it up ...... ?

Hi , welcome back , do you have anywhere near you that could bend you a link pipe ? If so buy a set of headers for a std GS, a can and get a link pipe bent to suit , and Bob's your aunties husband

Next time tanks virtually empty take it off and give it a swill out, 1/2 an hour , bet there will be a good bit of muck in the bottom , I'd do the float bowls to if you've got the time .... Shit happens

Poss @gsxr884 at CP racetec ?

What tyres did you use before ? I had Dunlops on a speed triple and thought they had quite a firm carcass compared with the metzlers which felt plush on bumpy back roads ....

Thanks for the update and the measurements , in the specials section did you mean the mk2 gsxf750 has bsr36ss carbs spaced as the bst ( earlier o/c ) type ? As every thing I've read says post 98 teapot750 are bsr

I dare say if you search a while there will be some angled needle nose pliers or some such that will get into the spots you need .... Probably with the aid of a dental mirror

May be Jota ?

Wonder if there would be any benefit in plumbing the turbo in if it's got water passages ? , not sure whether it's would run that much cooler as they're in the breeze more than a car , or whether it would just put more heat into the cooling system....
