I recently put a dg exhaust on my 89 exciter. Lots of info on this site about putting on an aftermarket exhaust suggested that you needed to rejet your main on the carbs. Well ive only put 15 miles on it since new plugs were put in and the pipe was installed. From what the plugs are sayin according to the chart in the tech section, they are in the good range. Well my concience is getting to me about the rejetting suggestions and that i should have it done, but I would like an opinion of someone who is knowledgable about these engines as to if they look good. This is my first snowmobile and wouldnt like to blow the motor because of my own stubborness and stupidity.
Pic of plugs, one looks a little leaner than the other. Leaner one is darker on one side, almost a black.
