The long extended carb problem I has was I assembled the needles with the large retaining washer UNDER the e-clip instead of over it so the needles were free to move up and down in the slide. Double check to see that you didn't make the same bone-headed move

Quote from: KevinCI hadn't followed this thread before. Sounds like something electrical to me. My GS is amazingly forgiving on the jetting, with only fairly subtle problems with the jetting off by large amounts. I can't imagine the jetting causing it stop acclerating past 7k.

If the throttle butterflies open all the way, and the slides go up all the way, I'd look for another problem. Could be the ignition box, or perhaps a coil cuts out at higher rpm.

It is running on both cylinders? One pipe isn't cool?

But would somethng electrical cause it to run different under a load?? I believe its running on both cylinders..lol.. i think i would notice that.. and if its not.. then im in for a treat because it has some useable power as is.

I didnt put washers on the needles yet.. i still have to find a hardware store around that has them.

oh i just realized what you meant.. nope the retaining washer is over the needles where it should be.

if not running on both cylinders youll know cause of sparks look way diffrent and will sound like cr@p if it will not go above 4 to 5 k rpm then dies out you could have a vacum problem maybe a leak in the mufflers gaskets or the gaskets on the top of the carbs could have holes in them as long as you have a stock or after market pipe that is good you should still have no problems and it should run fine on the stack carbs so take it in and have them do a test on your carbs they will be able to tell you what to do from there

Well.. i doubt a small exhaust leak would do this to a bike... ive run lawnmower motors without any muffler at all :lol: .

Besides, i have brand new exhaust gaskets. Brand new gaskets all around.. and the carb gaskets are fine. I took those diaphragms back because mine are perfect, rubbery, and without a hint of a leak. Ill try srinaths carbs... then i give up pretty much.

Guru is comin tomorrow to re check timing. If its on... which it better be or im an iddiot, then its gotta be carbs or electrical.. Srinath whats your take on the coils doing this??

Im seriously thinking about either a new R6 or a GSXR600.. most likely the GSXR. Ill probably ride the GS for this summer though.. then im either selling or trading her.

Ok...UPDATE:

Me and the bike Guru brainstormed a bit today.. and he suggested that we look at the electrical side of things.. because hes had some odd experiences with coils that test perfectly...and yet when replaced the bike runs fine. (and it didnt run good with them).

I had remembered that my one plug wire cap was screwy.. i went out and sure enough it popped right off . So i screwed it back into the wire... then popped it back on..the connection had been a little loose. I also re-sanded the ground point..and then took her for a ride.

All in all she pulls much better... still only revs to a certain point.. but a bit higher..look to rev to about 6-7k under load now..

I replaced the plugs and that helpd a bit too.. now the tach stops at 6-7k but i can hear it go slightly higher.. then cut.. i went about 40mph in first.. which was nice compared to the 25 i was getting. So i believe its electrical...

Anyone have working coils that i can borrow? I dont wanna drop 160 on new coils and not have them help.

NOW THE BAD STUFF:

I noticed the bike leaking oil pretty badly from the right side cover.. dripping it onto the pipe. Only when its running though. Its coming mostly from the small ignition cover.. but since this motor has been wrecked (new motor remember?) that cover is cracked. The oil is leaking from the rubber seal that goes around the wires leaving the cover. I dont have my old one either. So i proceeded to tighten the bolts, and i guess i tightened too much.. because i snapped one right off. :guns:  :nana:

So... ill be taking that stupid thing off and fixing it i guess.

I have ONE major thing thats bugging me now.. the engine runs extremely hot. Now i have no basis of comparison.. but it seems very hott. I know its running lean down low.. because i have stock pilots with a V&H. But would that make it too hott? I mean i cant check the oil with bare hands.. is this normal? Its very hott to the touch, but then again its air-cooled and it pulls heat to the outside i guess. I just wanna make sure im not gonna have preignition or detonation. Thanks guys..

Rashad,

I can't check my oil with my bare hands either - that stupid dipstick handle is aluminum, and it gets real hot! I don't thnk that is a valid check of engine temp.

The little round cover on the right side isn't supposed to have oil behind it. I think the ignition sender will work submerged in oil, but it isn't supposed to be. There is a shaft seal in the big right cover that must be leaking. It is only a short job to pull that cover and replace the seal and gasket.

Do a plug chop at different throttle openings (ride for a few minutes at the throttle opening you want to check, hit the kill switch and pull in the clutch at the same time), stop and check the plugs. That will give you a rough idea if it is lean or not - white is lean. You should start with clean plugs and all that but you can get a quick idea without that.

Just sold my coils for $10, sorry!

Kevin..Thanks a lot man... youve helped me out a lot in that post alone.  Ill have to remember that kill switch trick.

Shame about those coils tho... :nana:

If you replace the shaft seal in the over, make sure you tap it carefully, and squarely, in place with a socket or something to put the load out at the edges. When you put the cover on, the seal and the shaft should be lubed with some oil first. Be a bit careful putting the seal over the shaft.

OK now are we still doing the carb swap thing...I just managed to find the least mangled carbs, only seems to have a broken vaccum spigot.
I have also working tach. It has the 2 screws missing on the bottom but It was working when I crashed.
Cool. Keep me posted.
Srinath.

Srinath, yes please.. i definitely need to test the tach

Also.. i think it may be an electrical issue.. so im gonna go ahead and get different coils and see what happens.. so if you could just send the tach.. that would be cool.

EDIT: Ahh helll... if you want to send the carbs too, it wouldnt hurt if the coils didnt work afterall.

Coild fail at temperature...or at low rpm. They may prevent you from getting to a higher rpm but it will be obviously not running on 1 cyl. Oil on the ignition plate wont make a diff cos its mechanical contact based. My money is still on carburetion. Please check your connections etc in the ignition system...ahhh hell I'll send you the coils off my 91 which is currently sitting and will sit till I get with werase and get the rear tire on...So try it and send it back quick, crbs and tach...take your time.
Cool.
Srinath.

You want my coils too??? well do you...do you...Punk...
Cool.
Srinath.

Yea found it...
Cool.
Srinath.

OK!!!! UPDATE!!:

I got srinath's carbs, tach and coils...

I started with the tach. Guess what?...

FIRST THING:

My bike hasnt been going to 5-6k. My tach was dead wrong, its been going to like 8k or so.. like it used to. However, it still ran like shaZam! the whole way up. So i havent been breaking the bike in right, since i THOUGHT i was at 5k... but oh well, too late now.

SECOND THING:

Cleaned up srinaths carbs, kept his jets etc... bike immediately ran 100 times better... lean, but still better. I noticed a crazy backfire though, and i figured out the problem:

On the diaphragm covers... the little caps on top were broken off and causing a vaccuum leak. So i used my caps... PROBLEM SOLVED!! Bike runs like it used to!!!



So, srinath.... how much do you want for the tach and carbs? And if you want mine ill send them as well. I just have to get it jetted right now.

And man, i dont get it.... apparently it was the carb BODIES?!  hehe, whatever... i dont need the coils btw.. but thanks!!!

oh yeah, this bike isnt as quick off the line as i thought it was...will the proper 40 pilots help that? And the washers?

If not, im thinking about a smaller front sprocket.

Does this mean your ready to ride? Why are you still modding if your getting rid of it?

Well, i paid for insurance for a year... so ill keep it til then..

Then ill most likely keep it and use it for either track or fun. :mrgreen:

But i will have a GSXR600 or 750 next year.

Im ready to ride.. just need to set a date that i can make. I have to put in the new jets yet... but there are little stupid things to fix, like the rubber tank gasket, and loose tach etc...

Oh yeah, btw srinath.. "MR. Rashad Frelin"... i like that.... MR....
