Grizzly Dyno/Tuning
iv got a 04 660 grizzly its bored to 686 and has a hot cam, its intake snorkel its 1 1/2", i know i need to change it to 2" but it blows alittle black smock, the guy i got it from says it is jetted, is it normal to blow alittle black smoke or is it running rich cause my intakes not bug enough...
