whats my problem?

[big matt]

so, when i got my 79 gs 550e last july, it came with rebuilt carbs, all tuned up ready to ride, less than 8,000 miles.... bought for 700$ and i paid for carb rebuild kits and beer while he taught me how to do simple stuff like change the oil, replace battery, remove ignition cylinder to go get a new key cut, etc....with the help of this site, ive taught myself how to fix a few other problems too so lets tackle a new one......had I known installing pod filters would screw up so much, i would have never let him do it, but none the less, i've got after market pods, and i think the baffels in the exhaust have been tampered with due to the fact that at 5500 rpm i can set off a bunch of car alarms ( which i think is funny to be honest) when i got the bike it would fall on its face at almost 6k rpm but i could run through 1-6 gears with no problem. i think i've read almost all threads about pods and jetting so i pulled the carbs, and replaced the 92.5 stock jets with 110's.....what a difference! pulls right to the redline and was like riding a totally different bike....Now heres the next issue....when shifting to 4th gear while giving it half to full throttle it seems to bog down a bit at around 5k rpm...if i wind the throttle up slowly i can continue on to 5th gear, but it 5th it does the same thing. did i go up enough on the jets or is it a different problem? any suggestions appreciated!

You changed the jets without changing your needles and drilling out the slide for it?

If you answer yes, you have also mostlikely answered your question.

With pods its give and take, and unless you suck up money for the jet kit, you'll have to adjust your throttle rolling to compensate.

BTW, my buddy i bought the bike from is a moto nut and was finishing his mechanical engineering degree at Ohio state and finished the gs just in time for me before he moved up north for his first big job, so i don't have his ear to bend anymore.......

He's got VM carbs, you don't drill the slide

Raise your needle one notch

Then do plug chops and see how they look

Even easier, put the air box back on!

thanks ranger, you are correct, just changed the jets....so looks like i either need to find a jet kit with different needles, or start combing ebay for a stock airbox and boots which at this point i would give my "eye teeth" for. had i known a year ago, i wouldn't have agreed to letting him do it...is dyno jet the only company out there or is there others?

You don't need a jet kit = you already have adjustable needles

Try the Parts for Sale forum if you want to find an air box

I thought i had VM's at first, but definately bs32ss.....

Then it's not a 79!

Give us a picture

[big matt]

man, now i am confused....the frame says 79 gs550e, but the side covers say 550L...i ordered 4 jets for the vm from jets r us and when i took the bowls off, the jets were different...ran up to iron pony with one of the jets out of the carbs and they fixed me right up.....i always assumed it was an L model, until last weekend?

heading out to the garage now.....

Now I'm confused.. I went off the looks of your carbs, if in fact they are 32's do what I said, if not do what Big T said. One of us is right.

Take off the top cover, pull out the needle and look if it has slots for the clip ontop (inside) to adjust the needle height. They do however, closer up look to be 32's but just do that anyways to eliminate guess work.

[big matt]

will do that tomorow when i get home from work ranger...

Hi Mr. big matt,

Here's your picture:



Those are VM carbs.


Thank you for your indulgence,

Those are VM carbs.

Agreed, those are NOT BS32s.

THESE are BS32s:
