Only one cylinder fires!? Please help!

Just heard back from the mechanic who had cleaned out and re-synced my carbs. Says that only one cylinder Is firing, and that they both have power.

He did mention something about the coils both having identical charges (+), what would cause this to happen?

Any suggestions of where to start troubleshooting??

Thanks!

Thread bump.
Any ideas where to start looking for Problems that would cause only one of my cylinders to fire?

From what I can tell there are only a handful of gents operating on this forum that are capable of providing mechanical feedback, the rest just want to talk about stickers and helmet colors.

So, just wanted to say "thank you" To those out there who (IMO) exercise this forum's potential to educate others on Moto mechanics.

Did he mention anything about a bad plug wire or IC ignitor? You may have to trouble shoot the coils, plug wires and IC ignitor.

Hey guys thanks for all your help. It ended up being a wiring issue with my aftermarket trail tech speedo/tacho with rpm readout. It said to connect a wire directly to one of the coils. I must of misunderstood. It's firing on both cylinders now

Right now I'm in the process of syncing my carbs.

Question: if my rpms are climbing slowly when throttle is open and then falling in the same manner, is this something I can fix simply by adjusting the screw on the carbs? I am worried that it's an internal issue with the carbs ( maybe the guy I had clean them didn't get everything and now the valves are "stuck" ?)

Also, any tips when it comes to syncing the carbs would be greatly appreciated.

Thanks again guys!

If you think the valves are stuck, you can always open it up and check/adjust them. I just adjusted the valves on my bike this weekend. Not too difficult at all, but pretty time consuming.

That does sound to me like a carb sync problem. Haven't had to do that yet, so no tips, but that sounds to me like a typical carb sync symptom

Update: found that I am still not getting spark on left cylinder. Tested coil and found I am getting 3.1 ohms from primary leads (w/in specification) however, when testing primary lead to secondary lead. To elaborate in my simple terms; one test wire to a primary lead and one test wire to spark plug cap. Reading was 19.9 ohms (higher than spec) From the info provided above. It says that if the reading is above spec, there is an open lead somewhere and the coil needs to be replaced. Looked up coils on eBay. They're rather cheap but I wanted to ask one of you if you could confirm my testing was correct. I'm a visual learner, so I may have misunderstood the directions.

Thanks for looking,

Lauren
