Modding the top end from stock

[nickr234]

I am just mulling it over in my head, but i am think of getting some bigger carbs on my 78 gs 750. the best way to do this and still keep the 8 valve head is to use a 80's gs 850 head and use the CV carbs that are on those bikes. is this head compatible with the 70's gs 750's? I know the look VERY similar but you never so i thought i would differ to the experts. also could the same thing be done to a gs 1000 engine (just for future refernce if i ever get rich lol)


Also what about turning a set of stock carbs into a smothbore set with a little bigger bore (basicly i just want a bigger carb than the 26SS's). Is that possible and would it work well performance wise.

Thanks for any suggestions in advance,

You could do all that - straight bolt ons (other than the airboxes but i guess you would be using pods anyway).

VM28s would be the easiest route and give you the biggest bang for your buck without doing lots of other stuff as well (the 26s suit a 750 very well already).

Just remember if you go up on the carb throat size you will gain top end power at the loss of bottom end and mid range grunt.
Go to big and you will have lots of top end go, but it can be a cow to ride on the street due to the loss of mid range.
