Cheap 38's is going to be way better than 36's

If it's a 2002 (mk2) you'll probably have to swap to mk1 inlets too as the later ones (bsr carbs) have a different spacing to earlier gsxr/mk1 bandits (bst carbs)

Would the intake rubbers from the 86 gsxr1100 be the correct ones ? Or should I round up some newer from a mk1 ? Thx for feedback….

If I remember correctly the early slabside gsxr 1052 had 34mm carbs ( tin tops) so aren't suitable but the 89/90 slingshot 1127 had 36mm carbs (plastic tops) like the bandit 1200. I think the 750 shortstroke motor in the pre98 teapot/gsxf and 88/89 gsxr 750 slingshot also used 36mm bst carbs. The RS carbs in 36mm & 38mm both use a 42mm spigot which should fit the 36mm suzuki intakes ( not mk2bsr types )

There's a sticky at top of this section ref carb rubbers

Well got everything sorted out on the RS38s . Got new set of MK1 intake rubbers. Lord what a difference! They are some noisy sonaguns with low idle . Not bad at all around 1250 or so . But Wow…
