Bigger carbs

[nickr234]

Hello guys,

I have a 1978 gs 750. i was wondering how to correctly go about getting some bigger carbs on the 8 valve engine (like should i bore out the intakes on the engine). as most of you probably know the pre 80's engines have mikuni VM26's on there. and i would like to put on some 36 CV carbs, or mabye VM38s like the old z1 900s had.

Thanks for any tips in advance,

Nicholas Ryan Rasmussen.

Waste of time and effort unless you are also planning on making it an 850 or larger.
Even then, your BEST option is to get an '80-up cylinder head and either 32 or 34 CV carbs/boots for it.
BTDT.
Of course you could just get a set of 29mm Smooth-bores for what you currently have.

can i turn a set of 26's and make them into a set of 29 smothbores.

also i think the 850 head is still a 8 valve in the 80's (im looking for an 8 valve and not a 16). can the 750 and 850 heads be swaped (or a 1000 from the 70's for that matter)

also how good does your 1979 750 (1114) run performance wise
