I have a 1986 Maxim X that seems to run rough around 3700-4300 rpm's. The carbs were just gone through. could my coils be going bad? Any insight/help would be greatly appreciated.

Thanks

whats the spark look like . yellow could be a sign of a weak ing [not just coils]. Plus and dont take this the wrong way did a reputatable person do the job?

I have not looked at the spark yet. The carbs were gone through by a certified honda (yes i know, but there is no other dealership, mechanic in my area) dealer. They worked on them 3 years back and ran fine. I did not ride the bike all last summer and figured that it should be ridden some. I will take a look at the spark and see what it looks like.

Also, the other night when I was riding it seemed to want to just up and die on me. When I would be running it a bit hard, and the rpm's would get up to around 7000 it was like someone would hit the kill switch. Does anyone know what this problem could be? It was not necessarily a humid night, no different than other times. It did that quite a bit 1 night, and I went riding the next night and you could run it to redline if you wanted with no hesitation at all.
