TOPIC:

So I see a lot of topic covering carbs for a 1075 with new cams but not stock cams. Also what tuning should be done to my stock head to help it other than porting (valve lift). Porting will happen next spring into summer by a member on here. Till then what would be a good choice for carbs/tuning?

That's because the 1075 pistons alone really don't create a "demand" for more fuel. The bike I have (been fiddling with all summer) has 1075 pistons, and stock cams. The previous owner had some light port work done, but it has stock cams. I run the stock VM26's, and simply re-jetted them to match the exhaust & K&N's. When I am not chasing other unrelated gremlins down, the bike runs very well with them. At least for me, I don't think it would be worth the money or the time involved retuning (or paying someone to dyno tune) a different set of carbs, without swapping for hotter cams and getting some "real" port work done. The big changes in HP are not going to be achieved unless you do the 3 things and make them compliment one another - increase displacement, hotter cams, carbs. So one of the things you might want to think about doing to that head when it's off the bike is having it clearanced for bigger cams down the road.... and run your stock carbs til then. But that's just me.

mikuni 28 mm 79-80

I have an 80 with a 1075, mild porting, stock cams & dyna ignition, & running Mikuni RS 34 Flatslides ....BIG difference !!, & the 34s would be great with more head work & bigger cams

Keihin CR Special Roundslide Racing Carburetors - 31mm CR31

I saw those (above) but I have the 29 pumpers. I have dyna ignition. Right now I have a little bit of leak down on my exhaust valves. Not sure if its the valves or the seating. Problem is that my proformance shop is full, 3-8 weeks out. I want to get this all together in a month because we are moving to tampa.

I have mybe 60 sets of carbs ok only 50 so I just bought some cr31 3055 to wake this puppy up . got 3 up and down on the mains .Well my head is a 1100 gpz so it flows with a crh job ist actualy a 83elr head but same as gpz 1100 bathtub

for your head and stock cams you should keep what you have and spend money some where else.

run a can of seafoam thru it and clean up the seats

I fully rebuilt my carbs already. Not a big fan of sea foam.

Get some adjustable cams sprockets and degree it for cheap thrills ........

I am sorry Peter1958...I dont know what those are or what they look like. I dont mean to be dumb but I have never heard of that before.
