It's more likely a std one. GSXR400 RN GK76A-105595
GSXR400 RK GK76A-106574. Yours is a RK model going from this info.

Doesn’t make sense as surely they didn’t do a K twice. I’ve a RK and it’s 89 so you would then go L,M,N,P,R etc.
I’d say it should read NK to donate an N model SP.

Thanks guys can't make sense of it tbh looks as if it's had a bump so I don't no if the forks have been swapped there USD forks but not fully adjustable it does have the shorter wheelbase

That would make sense as N would be 1992 which is the last year of the SPll.
Even the grey importers used to bring damaged bikes in and then bit fit them with parts from another bike so the forks could have been on it for years.

If you have a correct wheel base you will also have the single 12 pin cdi, larger 35mm carbs with TPS and the vacuum system on the air box that pressurises the float bowls.
Not sure of the gearing on the SPll but the early SP had the super high first gear that needs thousands of rpm to pull off.

It's definitely got a tps sensor on the left hand side and a shorter wheelbase haven't checked the cdi and them vacuum pipes r missing will have to have a look it's registered as a 92 model but that can be wrong thanks for the reply

Should the engine number match the frame number ?

Don’t think they do, sure matching numbers stopped in the late 70s or early 80s and like yours are usually a hundred or so apart.

Got back from work last night checked the cdi pulled connection off has 12 pins but the vacuum pipes are missing from airbox

It should have pipes from the float bowls that connect to a pipe that comes from a small black vacuum switch (box) that is on the air box.
This will open and pressurise the float bowls as the airbox pressure changes.
