1990 Suzuki LT 4wd need help running issue

[Ahren Longo]

If you know you're getting good fuel I'd go the ignition system route. I've had this happen in 2 strokes. It'll have great spark while cranking slow but when you crank it fast the spark goes away. May have a faulty pickup on the stator or something else.

ah i wish i could take credit i was just quoting @Kent Mettler as it was great information! 

[Frank Angerano]

We all go to fuel, poor spark etc. This was a good find both as a problem solver and Info going foreword to help others.  I personally would have never thought that problem existed.  

It just shows how valuable a site like Quadcrazy is ! 💪

Alright Shane and Kent! Great job everyone . This is the reason for sites like these . Bunch of helpful, like minded individuals all pitching in to get a bike running.

Joseph, you are more than welcome buddy. I can't count how many bikes, trikes , quads , or scooters other gentlemen like Shane or Kent have brought back to life for me . Cheers to my fellow members! I LuV iT!

Glad to know you got it fixed. Lot of good advice here.

I would say to that you have to let it warm up longer they are cold blooded.

i have a honda foreman that was doing the same thing, turned out to be the run jet in the carb. idle jet was fine which allowed it to idle perfect but died as soon as you throttled up.

seen air vapor lock on gas tank.  air into tank at gas cap was filled with mud/dirt- it would run 3-10 seconds then quit.  no gas could be sucked out of tank as no air could come in.

Good, informative topic.

 

I think I'll go check my regulator.
