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....

Not pretty in there,makes you wonder how many times it had been "fully serviced" before , to be fair vstroms generally are pretty tough in both 650 and thousands . Hate rip off merchants

I also believe @imagodoes this kind of work through his business and is an OSS trader too maybe drop him a pm ?

Could have been a worn out thread but one word springs to mind ..... Locktite

Whatever works for you , I like studs where possible for stuff like exhaust headers or intakes on cars Etc that may be on and off relatively frequently as it reduces the risk of damaging the threads in a head casting , it's not suitable for every scenario but it's fine on headers just put them in after the motors in the frame to give yourself a little more wiggle room and less chance of scratching the paint or powder coat

And if when you fit the studs you use brass nuts ,they won't rust onto the studs and are soft enough not to strip the threads off the studs if you over tighten them unlike stainless nuts.....
