Starter Motor covers.

Will a cover from a 750/1127 fit a Mk1 B12? Nothing in Frankensteins Pages, unfortunately. FBOAB???

Are 750/1127 interchangeable to start with ?

1127 same as 1157 though from what i remember on mine.

From ‘The Pages’

STARTER MOTOR COVERS. 

The startermotor covers from the 1127’s are all the same (The startermotor covers from the 1052 engines are not the same) The 1127 covers can be recognized by a kind of bubble, to accommodate the bigger starter motor. The 600′ and 750’s have a smaller starter motor, and the top line of these covers is straight. (I believe the 1052 motors also have this smaller starter motor and cover). Covers can be swapped among the 600’s and 750’s, but an 1127 cover only fits an 1127.

I’ve read it properly this time!

So, no! Neither 750/1050 or 1127 covers will fit. All part no’s are different.  B12 covers must only fit B12’s ….. or, do they???

I can confirm that very easily since i have both on the bench without their covers fitted

[Joseph]

But yes, i'm pretty certain that 1127=1157

Got to be 100%. I’m about to buy an 1127 cover if definite fit!

Also need to know if it’ll seat on faces over starter gear internals.

Yep. 1127 and 1157 same.

1052 and all 750 same.

600. Who cares.

Awe poor 600's

Cheers, lads!

It is always useful to know which 600 bits are the same as anything on the bigger bikes because when parts are advertised as 600, they tend to be much cheaper. This is a distinct bonus for tight-arses such as me

Gsxf/b600 will fit the gsxr/gsxf750 motors and the gsxr1052

That's a 1127/1157 cover no idea what the gasket is picked up as a bandit 12 but way too small
