That polished alloy SO sets off that Cadbury purple frame , such an excellent choice

Era defining pipe i think , big air cooled bike , skinny jeans , mullet , white high tops ......

Our lasses mate, last MOT was advised brake pads were low and would need replacing soon ..... This MOT needed new discs and pads

As above, the j/k frames are I believe slightly smaller than the l/m ones so a dot head on an 1127/1157 would be even tighter in your 89(k) frame ... Personally I'd look for as low a milage bandit 12 engine (they carried on 13/14 years after the gsxr 1127 stopped being made) and fit the gsxr cams and change the sump to fit your Yoshi

1st thing I thought was Hoover from bloodrunners but that's showing my age I guess.... Edit : just posted something similar

Holey Moley that's an impressive pair ...... Of headlamps

The problem with many of the cheap Eblag/Amazon jobs is the filter element isn't sealed to the body of the filter and dirty fuel bypasses the element ..... As usual with the cheap stuff it's probably a copy of a copy ..... Or the quality control rejects

Have a look at the Mann wk512 or similar, metal body, oe quality filter maker , but maybe a bit bulky for a tidy installation think they're designed for injection but don't see why they wouldn't filter from a gravity feed , they may have something smaller as may bosch....

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 ...... ?
