[img]i/expressions/face-icon-small-frown.gif[/img]Hey all, Problem with my '03 600. After my last time riding in june, Ran fine, parked it, shut off gas, then went to start it last week, spins over fine but won't fire. Of course gas turned on and gas in tank. Has never once had any problems with stale gas issues since new and I always use seafoam or sta-bil. People have told me gas nowdays goes stale VERY quickly because of all the additives they put in, maybe less than a week?? Am I dealing with a fuel or maybe a spark problem?? I can't do much tinkering myself to figure it out due to its location. One dealer was pretty confident I had a gummed up carb yet another dealer thought an ignition issue???? Any opinions welcome, Thanks all who reply.

 

Pull plugs first ground to frame, check for spark. Then go from there,process of elimination. Good luck

 

yes you need to find out if its getting any fire by doing what he said. i would doubt carb is gummed up since you just used it in june but you never can tell w/ this bad gas.

 

[img]i/expressions/face-icon-small-confused.gif[/img]Thanks guys. Today I pulled the right spark plug out, it looks alittle crusty(original ones). Cleaned it up a bit and grounded it to the ground bolt on the frame while cranking. I did'nt see much of any spark. Questions: I should be able to test just one with the other one still seated right? Also whats the easest way to access the left side plug. My hands are way too big to get much room around there. How do you disconnect the clutch inlet duct up next to the fuel tank?? If I can move that away I maybe could get to the other one better. I bought new NGK plugs to replace the Champions. Whats the possibility I just have worn out bad plugs?? All my riding buddies all agree I have an ignition problem more than a fuel problem as they all leave their bikes sitting long term without any fuel starting issues. Thanks again for your replies

 

No spark, no fire.
Kill switch?
Fuse?

 

[img]i/expressions/face-icon-small-frown.gif[/img]Kill switch is fine, it cranks over fine, Fuse????? Not sure where to look for that one. thanks

 

Not sure if your sp 600 has a fuel pump or not but i have a 2000 325 trailboss and when i bought it it had sat for a while put in new plug new air and fuel filters still no start so i removed air filter and sprayed starting fluid in it and it would start and die found out all i had too do was prime the fuel pump by disconnecting the fuel inlet line at pump and blowing in it too prime it and it runs perfect now! sorry about long post just trying to help ya!

[img]i/expressions/face-icon-small-happy.gif[/img] ABOUT a 100 percent chance plugs worn out if you still have the lawnmower plugs(champion) still in! BIG hands are my problem to,but can eventually get the left side out,just tight spot! Good luck Air duct goes over tank,have to remove front cab,unbolt tank,slide back to remove duct! TOO much work! if you have a flex ratchet,can make job a little easier

 

[img]i/expressions/face-icon-small-frown.gif[/img]Thanks for all your help O.P.T. Tonight I still could'nt see any spark from the new plug on right. I gave up for tonight tring to get to the left side (getting dark, no power in my rental garage plus way too hot!!) I did open the carb bowl drain screw and let about 1/2 cup run out. Fuel looked clean/normal with no visible sediment. Took air filters out (time to reoil anyway) gave it a shot of starting fluid in air intake, still nothing. I'm leaning more towards an ignition problem. Read the post here about Wal-Mart batteries that I replied to, what"s your opinion on what my dealer said??? Thanks again.

 

Yuasa supplies Polaris batteries, But as long as cross reference you can go cheaper,may or may not last as long. A lot depends on HOW its used. Batteries loose approximately 1 percent charge daily if left setting,can also increase sulfation and plate shorting. If kept topped off with distilled water(non sealed batteries) and used frequently or use a battery tender will usually get some years out of. THERE are exceptions,have had some batteries JUST not good straight out of the box. Usually these have been our lower line Bikemaster! Have only had very few bad ones from Yuasa and Interstate. I change a lot every year for HUNTERS ,use em in the fall and winter,let set all summer. Just the opposite for pwc owners,use em all summer,let set all winter Some come in dry and white from sulfation.
