1979 GS1000 Carb Identification

[raistian77]

Those are aftermarket VM29 "smoothbore" carbs. Cleaned up they sell for $600+ on ebay. Nice score.

yeah, nice find. Dont feel bad mine is a frankenbike also
combination of 79,82,84 G and GL parts

29mm smoothbore.Has the others said, if the motor dosent have gofast parts in it you can have a good price for these carbs.

Sorry, guys. I think they're stock pistons. It was pretty cruddy in there but I could make out a dome shape with a flat side and an arrow. Much like this one:

I haven't checked compression yet, but I don't have high hopes. Your advice has been awesome so far. My question now is what I should do?

Should I sell the carbs/mismatched pieces and get some stock ones?

Should I buy the front and back end off of the 1989 GSXR 1100 for $500 on CL and make it into a streetfighter? Twin or Monoshock?

Should I just reinstall the carbs, get the right jets and ride as is?

OR

Just part the whole thing and get something that is already ready to ride?

Again, I appreciate all your input.

Hi,
if youre handy, keep the bike , sell the carb to take the 1100 gsxr rolling gear and a set of stock carb with pods.If you lucky you will end with some money left.
my 1000 is modded and it will have a bigbore motor in it next year.
There are no cure for this.
My plan was to monoshocked the 1000, but i really like the look of the 5.5 rim with the twin shocks.

Yes, the Economics grad in me would agree this balances cost efficiency vs project indulgence, however, is the value of these carbs going to go down?

Why not have a little fun, keep the carbs and bigbore the motor? I guess if you bore out the motor, you can never get rid of the carbs.....

Don't get me wrong, a set just sold on eBay a few minutes ago for $832 so these will most likely find themselves on there. I guess I'm just thinking out loud....

i have RS carbs waiting on a shelf for the bigbore motor.if it was me i would sell the carb on ebay.A new rs set is lower that the 832$ If you go bigbore you will probably go with bigger carbs than the 29, like vm33.

i would keep the carbs and build a motor to put them on
33mm smoothies are too big for a moderate 1000 motor

i have in my 78 1000
stage one cams Degreed 106 106
head is ported and polished
larger intake valves
heavy duty valve spring
stock pistons (bigbore 1085 in the future)
hindle 4 into 1
K&N pod filters
with the 29mm smoothies it sings beautifully 33's are too big tried em and sold em and put the 29's back on i also had a very good friend who had a built 1085 motor and he had the 33's and went back to the 29's because they were a better fit for the motor
33's are for a big bore 1100++ motor
at 3500ft i have 27.5 pilots 117.5 mains and my needles are on P2
and it is a big bag of fun from 2 to 6 grand and then from 6 to 9 it just screams when you open up the throttle wide
i have no problems running at 200+KPH for as long as i want to
and the bike is still civil enough to ride in town with no problems at all
here is a picture for you

Spyderman, that bike is SICK.

I checked compression and it was 120 across the board.

I think I may keep the carbs for the time being. If running pod filters and a stock exhaust, what do you think would be a good starting jet size for the VM29s? Again, they're currently 122.5.

I was a bit impulsive a bought the 89 GSXR setup: Complete front end, swingarm, including brakes, tires and wheels.

After doing a little more research I think I may have bit off more than I can chew (or want to spend time on).

You think anyone would be interested in a complete suspension and wheel set for an 1989 GSXR 1100?

[kochic]

i may be interested in the forks assy.i have usd on my bike and want to go back to rwu.
Just pm me.

I will for warn you , if you plan on putting them on E-bay members here would probably like you better if you gave them first crack at them. Just saying
