carbs back on. One pipe cold. GS1100G

Hey Dave,

That looks pretty dang good! Nice work. Practice makes perfect.

This is where I ended up the first time I used my Carbtune.



But I got them synced a little closer this time. Next time you will too.


All the best to you and yours,

Cliff

Hey Dave,

Cliff, I purposely had the 1&4 a little higher than 2&3, cuz that is what Suki manaul said to do (and other things I read). SOmething about the crossover in the exhaust between 2&3 pipe.
And I noticed at higher rpm (5k) that it evened out.

But I think that little differnce is not much of a difference. THe MotionPro scale is about ten inches long. And just lightly pushing on the screw or turning the nut (without really turning screw) is enough to make the MotionPro change a good portion of a mark, which is more than that difference than I have between 1&4 and 2&3.

- Have seen comments about having all 4 equall if staight pipes 4 into 4.

- I saw your comment in your other posting about this time you tried having all four equall, and you said ran smooth.

- MotionPro manaul says is intended for adjusting all equall, and not suitable if intneding to adjust differently. ANd then says tha bikes with the exhaust crossover should be adjusted diffeently. DOAHHHhhh.

- Suzuki manaul says to adjust 1&4 about "half a ball" higher, but that is on the Zuki specific instrument. Your BassCliffBikeCliff tutorial, I think, sayes about 1 mm difference, I think Brians said 3 mm higher, both on the CarbTune, I dont remeber the specifics at the moments, but one stated a larger number than the other. I was trying to figure out how many marks that would be on the MotionPro.

- But, I was having enough other trouble trying to get ANY adjustment on it, even or 1-4 higher than 2-3. SO I went for even and then bring 1 & 4 just slightly higher.

Certainly revs up faster than it did before.
ANd Idled for a long time (with fan) without the idle speed creeping up, so that is the improvemnt I was looking for.

(If you ask why I got a MOtionPro, the answer is beacuse I did not research it enough. I procrastinated doing anything, and then ordered what I saw in the Catalog I had.)

Hi Dave,

Yes, the manual isn't very specific with its synchronization measurement criteria. How much is "half a ball"? My Carbtune, as you see, is metered in cmHg (centimeters of Mercury), an atmospheric pressure measurement. You can convert cmHg to 'pounds per square foot' or 'pounds per square inch' or even 'kilograms per square meter'. You get the idea.

So is "half a ball" 1 cmHg? Or 2 cmHg? Or 1/2 cmHg? Who knows?

I think the next time I sync I will try it like you did - start by getting them all even, then moving #1 and #4 slightly higher, perhaps 1/2 cmHg, and see if I can get it smoother. But I gotta tell you, it's pretty dang smooth right now. I'm just going to ride it for a while.


Thank you for your indulgence,

BassCliff

whaa hooo yee-haaaa

Went for a test ride this morning.

whaaa hoooo

Starts well, idles well on choke, rpms rize smoothly, turn down coke a bit and then a bit more, then idles well without choke.
Revs well to throttle blips.
Runs Smooth.

Ran some local roads. Ran up and down state highway some, was going faster than I needed too fast then I knew it.

All is good I will say.

Then went for breakfast, and went down past peir & beach.

Now to deal with some more annoyuing rattles and buzzing in the fairing.

Thanks again guys.

Dave

Nice work Dave. It's nice to read a tread where the poster has done his home work instead of wondering why their (unmaintained) 30 year old bike isn't running right. Have fun!
