Plugs...

See attachments--

These plugs were in my bike about a month and about 200 miles. It is a 77 XS360. It has been a bit hard to hot start but runs great while riding. Sometimes at idle it will misfire some but nothing major. Stock airbox and filters. MAC 2 into 1 exhaust.

What do you guys think? I have had trouble with the hot starting for a while but have tuned on the carburetors a lot and currently it will USUALLY hot start on about 5 kicks but it has taken 10+ at times.

I'm not a pro at this stuff but I'm not a newbie either but can't seem to get this figured out.

Thanks.

You’ve got stuff in your gas. That’s normally from too much of a fuel additive or your tank is got the rust. New plugs are $4.75.

Youre probably too rich on the idle, and the condition of those plugs probably doesnt help.. Not saying they look bad though. The plugs definitely dont look balanced though. You need to check your valve lash and get your points/timing right. Then you need to sync the carbs.

I'm guessing the lighter one is from the right cylinder?

No actually the first photo is the left cylinder.
