#1 and #2 exhausts way cooler

[Snowdiver]

I have a Kirker four into one exhaust and after running for five minutes the #1 and #2 exhausts are easy to touch. The #3 and #4 are hot. What a m I missing here?

What have you done to the bike?
What do the spark plugs look like from those cylinders?

I cleaned the carbs and replaced the float bowl gaskets. I just got this bike a couple of weeks ago. It starts easy and seems to run fine. I just thought I'd touch the pipes and noticed the huge difference in temp?

I only took out #1 plug and it looked slightly wet and I looked into the plug hole and it looked wet also. I thought the coils were for 1&4, 2&3, so a bad coil isn't the problem, right?

Right.
Where the plug wire goes into the cap twist it out and cut it to get a nice copper wire and rethread it.

Thanks, I will do that tomorrow.

One more thing, I see that the pipes have a blue tint to them. I think that the color should be more golden. Maybe it is tuned to lean?

Seal up that airbox.
Replace the intake o-rings if you have them
