gs850 carb swap??

[Guest]

I have a 81gs850g and I'd like to swap the carbs. What is a good swap for this bike? It has the vacuum secondaries on it which work fine. I'm tryin to get a little more oomph outta of this bike.

Good luck.

There are no "secondaries" on the carbs.

About the only performance upgrade is to remove the engine and slide a 1000G or 1100G engine in its' place.

If you were looking for a rocket-fast bike, you chose the wrong one.

The 850 is a great bike (have had up to four here at the same time, still have two), but "quick" it's not.

Isn't the engine just a bored 750 in a 1000 frame? And you wouldn't know anyone with a set of intake manifold boots would you?

Pretty much, if you ignore the chain vs shaft thing.

And you wouldn't know anyone with a set of intake manifold boots would you?

Any of the online vendors, including Z1.

Ok thank you for your help. Its my first bike. I bought the bike in pieces almost have it back together. I'd like to swap the stock pipes out with something not so quiet. Any.suggestions? Also the rear turn signals... How do they attach? They came in a box with a long bolt through them and I've tried to attach them to the spot on the frame but it don't look right. Am I missing a bracket? The start button don't work either and I just installed new solenoid. Only paid 400 for bike. Sorry to rattle on but you seem to know your stuff.

My suggestion would be to enjoy the quiet. Loud pipes do more to damage motorcyclists' reputation than they do to alert nearby traffic.

Also the rear turn signals... How do they attach? They came in a box with a long bolt through them and I've tried to attach them to the spot on the frame but it don't look right. Am I missing a bracket?

Possibly, as there is a bracket involved. That bracket is part numbers 25 and 26 in this parts diagram:

The start button don't work either and I just installed new solenoid.

Did you pull the clutch lever? There is a "safety" switch there that many of us bypass.

Only paid 400 for bike.

Sounds good, but please don't use that as an excuse for not buying stuff for the bike. Too many times, we will mention that some part needs to be changed or we might recommend a particular tool. The response is "but that's more than I paid for the bike". Rather than use the bike's price as an excuse, think of it as saving money on the purchase so you can better afford the things you need to get it back on the road safely.

I'd Sorry to rattle on but you seem to know your stuff.

Thanks for noticing.

Some of us have been doing this for quite a while. A few have been working on/with these bikes since they were new.

The GS850G is one of the (if not THE) heaviest production bikes that Suzuki built. As Steve said, quick it is not. But powerful it is.

If it's not even running yet, how do you know it needs more 'oomph'?

The general consensus of the collective here is to get your bike-in-a-box running and running well in stock form first, by performing all those maintenance items that the previous owners ignored. Then if you want to diddle with it, at least you're starting from a working machine.

It's your bike, you're welcome to modify it however you like. But know this - any combination of airbox/filter/carburetor/exhaust modifications can send you down a long frustrating path to get the jetting right. It's much worse if the bike is already a basket case.

There are many Suzuki dealers with online parts diagrams. Here's one that used often: Parts Outlaw
