Starting issue

[Ickaruz]

I'm almost done working out all the bugs with my 85 Suzuki Gs 700. The last issue was lack of venting in the tank because I had sealed up 2 holes inside when I treated the tank. Anyway, the bike runs pretty nice after it warms up but starting it is weird. I have to turn the idle screw several times clockwise to get it to idle. It idles rough for a bit and slowly the idle picks up. As it does I turn the screw counter clockwise a bit to bring it back down. After 2 minutes of this the bike seems ready to go. If I started it without this process it would start fine but instantly die. It also does not like choke. Anyone have a clue as to what may be going on? I was thinking that maybe the vacuum hose going from the tank to the carb maybe a bit too long. Would that effect it? In otherwords I'm clueless at this point.

HAve you soaked and rebuilt the carbs? Checked for vacuum leaks; air filter in place and oiled; adjusted the valves; replaced o-rings where needed; synched the carbs? All needs to be done to get things to run right.

somethings wrong in the carbs enrichment circuit
and/or the pilot mixture screws are set incorrectly
and/or you have bad air leaks in the intake system
and/or maybe you have no air-filter

Cleaned the carbs and has them synched. That was before I figured out the venting problem though so maybe I should synch again. There is an air filter but for ha haas I will replace. I've never checked the valves so I need to get on that. Is that a lengthy task?

Go to Basscliff's website, it will walk you through it.

Hi Mr. lckaruz,

Always adjust valves first, then sync carbs. The first time I did a valve check/adjust, it took me over 4 hours. Now I can do it in less than 2. I think the 16-valve motors can go even quicker because you don't have to swap shims.

Thank you for your indulgence,

Thanks again all for the advice. I will prceed with the valve adjustment and re synch. My bike test is coming up so I will hold off till after because...well its me. I should be known as Mr Nothing Seems To Go As Planned but that is a bit wordy. I'd be lost without you guys, thanks again!

while tight valves do contribute to the cold start difficulties, your problem sounds past just the valve adjustment
