1977 GS 750 mutt..Carb problem/identification.

Is that a 4 into 2 exhaust on that bike?

Looks to be but doesn't look stock either... Maybe a Mac?

Looking at the slide he has in his hand in the pic it looks like (what you can see of it) a flat or radial slide maybe?
And looking at it closer im seeing what appears to be the Keihin logo on the bottom of the carb/bowl there.
Man, what a Frankenstein! But it's got potential. More pics! Is that a stock rear rim with a bandit or Katana front. Radial and bias tires on the same bike is a no no...
I though maybe they were bandit forks but the calipers don't look right. Tiny pic though..

They are all torn down and ready for action...he sent me a PM saying he ordered the orings...so last call. Am i pulling the trigger or not?

more pictures as requested, looks like someone has cleaned up the intake at least. Also its a 4 to 2 exhaust. The plates are good until 11-2012 so someone had it on the road. I also noticed the back tire is bald, so either then put on a used one or someone has been laying down some rubber.

Will do thanks for all the help. I am unsure if the bike is actually 1000ccs or 750cc what would you guys do tune for 750 or 1000cc

Well, you can't bore a 750 to 1000. I think 840cc is the biggest piston kit available

What does it say on the motor serial number?

BTW, the aluminum swing arm (off a 1100) and the 90s katana front end are popular upgrades

Looks like someone has cleaned up that intake port. dunno about those carbs, 80~90's Yamaha's possibly. ginsu headlight, turn signals and carb boots, stock style rear shocks, 4 into 2 exhaust. my gut thinks the bikes nothing but a bodge...

[chuck hahn]

Got the brass bits and bowls already in the dip..I will clean him up a sweet set and send him all the info on the jetting. I gotts get me one of those loops Dale..cant see those little stampings even with the bifocals..LOL As for what the carbs are..doesnt matter really. Jap Bike Randy will know instantly what they are. He may even want them for a project??

No but you can bore (apparently) a set of 850 jugs to 920...

Chuck its a done deal. Your carbs and $75 went out in the mail today. I also ordered the o-ring kit and intake o rings. I had them shipped to your addy.

[TheCafeKid]

Wait, you gave him those carbs AND $75????

Wow...

[chuck hahn]

Im rebuilding and cleaning theses carbs too...75 for the carbs and 4 intake boots. Carbs i considered a swap for labor and return shipping..heck I dont even know what those carbs are. Someone said Yamaha carbs?? Dont know myself. If they bring me 50 or 60 buck resell them thats what i made for labor. I wont ever use them thats for sure. If they turn out to be something really extravagant and worth some seriuos dough then I will throw him a bone. And as always, he has my no fuss guarentee..if he doesnt like the carbs i send then he returns them and i return his..hes got nothing to loose.
