Road down the street to gas up. After filling up I went back home. Half a mile down the road the bike started sputtering all of the sudden, it happened all at once. Sounds like a lawnmower. I went on a ride close to 100 miles thinking it was bad gas. It kept the same problem the whole way. I filled up at a different station and the problem kept on. I checked to see if any vaccum lines were disconected but all seems good. I just sync'd the carbs a few weeks ago and It was running great . Like I said, this happened all of the sudden.

Any Ideas?

 

Spark plug(s) is my input. Changes your inline 4 to an RX-7 (old school) or into a v-twin.... Pull the plugs and one will be fouled.

 

Ugh! I just spent $30 on plugs only to find out that the plug on the #4 carb vaccum port came out! I just screwed it back in and back to normal!

 

like poo

 

Resell to plugs? Or return with receipt...my suggest next time if any weird noise or anything out of norm? Stop! Don't ride bike.. lucky it did get any worst...which will cost much more ...pull over and diagnose ..

 

id just keep the plugs, you'll need em eventually

 

I was recommending you to "pull the plugs"(i.e. remove them and check to see if one was fouled). Now you know if you want to troubleshoot something you need to check what is wrong before you go buying stuff to fix something that isn't broke. $30 is an inexpensive lesson. Just a tip.

 

At least it was something simple. Next time don't try to ride it back to running right, that can lead to all sorts of nastys. And yes, $30 is a cheap lesson, trust me. Years ago I whacked my big block Chevy valve train 'cuz I was mad and it cost me over $300. Lol! Prolly cost a lot more now!
