Higher RPM problems.

Kinda scary in my book.


82Shafty had a decent suggestion, here is another along the same idea: do whatever it takes to make it run "bad", then move your "choke". If it gets better, it's running lean, the "choke" is adding fuel to richen the mixture. Removing the filter as 82Shafty suggests will lean it out if it's running rich, so now you know how to check both sides of the mixture.

.

This is why I went the other way because applying some choke made no difference either way. It takes just a few minutes on the side of the road and can really narrow down which way the bike needs to be tuned.

This bike could have dried spaghetti for intake boot o-rings for all we know.

Do NOT add Diesel Oil, add motor oil for Diesel engines. Huge difference. .

I think you may have misunderstood it to mean diesel fuel.

Motorcraft 15-40 and Rotella 15-40 are not diesel fuels, but diesel ENGINE oils.... sometimes referred to as diesel oil or HDEO in the shop.

I didn't misunderstand, I didn't want him to misunderstand.

Hey guys, been awhile since i've been on here but I think it's time for an update.

So I looked at the bike a whole lot over the weekend and noticed a crap load of wires unattached and plugged them all back in where they went. I completely dissambled the gas tank and petcock and cleaned it and sealed it and then put new hoses on the petcock. Well guess what? SHE RUNS! I'm not sure exacty what was wrong, if just maybe the jets were clogged and whatever was in there passed through or something in my petcock, new oil or what, but I don't care. All I know is that it runs again! Thanks for the help, I really appriciated it.

"He who knows not and knows he knows not knows more than he who knows not and knows not he knows not...."

SuzukiGS - there is no shame in being ignorant/not knowledgeable; we all had to start somewhere.

This thread is like listening to a French guy trying to talk to the Swahili Tribe (in a most funny/entertaining way mind you). We all assume you can understand Swahili.

Sometimes the mechanical advance can get sticky/rusty and a shot of cleaner and lube will get it moving smoothly.

reply:

No, in neutral it has the same issue. I've cleaned the airbox and filter as well.

Translation in Suz GS's mind: "mechanical advance = 'bike is going'; "neutral" = 'bike ain't going'

So not surprisingly, in this later exchange:

Now, when you had the carbs apart did you check to make sure the correct jets were in there ?

I never took the carbs apart. I'm too afraid to try and do that

SuzukiGS dude: be afraid. You still have a lot to learn. It's ok. It's ok to "punt" if something is out of your league and employ a good mechanic once in a while Even guys like me who have rebuilt car carbs and done all kinds of other manner of wrenching are allowed to "punt".

I'm glad she runs better. Problem is: you have no idea why (and don't care and I can absolutely appreciate that). You broke the cardinal rule of mechanical problem solving (so note for future reference): do ONE thing at a time so you can isolate the problem.

To wit, any wires that were unattached (which wires? We don't need to know, you need to know) that could contribute to how the bikes runs, if unattached would cause the bike to not run at all (e.g. coils, DynaS) or would not have any short-term effect (e.g. RR wires, Stator wires), so my guess is that whatever wires you plugged in had nothing to do with the problem.

Rust from gas tank and/or petcock certainly could have caused the problem, and like a kidney stone, can "pass" and all is well again (if you're lucky and sounds like you were; I have personally experienced this as well). What did you do to "seal" and "clean" the gas tank?

Do yourself, your now fine running bike, and us one more favor: get 4 new spark plugs, install, remove old plugs and post of pic of the 4 old ones. Guys like Steve, Chef, and TKent are awesome - listen to them and they will help you both learn and keep your bike running great.

BTW, Spectro motorcycle oils are excellent (but pricey) as well. Have used Golden Spectro for 20+ years, no problems.

I understood exactly what everyone was saying. And with the petcock, I bought new one for it, thats what I meant, because it leaked. I put a new oil filter in it as well as new oil and 4 new plugs. I had tried to clean to plugs before I bought new ones so they won't look even remotely close to when I pulled the out originally. I can explain what they looked like, but thats all. I replaced them with NGK B8ES Plugs as well.

But the plugs, they were a very dark black. Very carbon fouled I want to say. A new set of plugs took the bike from running okay to running great.
