No rev like plugs are fouled but they are ok. Its for sure running rich since i added oil to fuel per destructions. i was at low elevation today roughly 6000ft and had recommended 1-2-2-1 weight setup. Not very impressed. Would have rather rode my wifes 600 polaris than this gutless turd. ANY help is greatly appreciated!!! Ive checked all the connections which a lot of fun at -10 deg with the sweet hood cat has. Why cant a hood open??? Theres a marvel idea!
