check service manual first, there should be a trouble shoot section for the gauge/tach display, start from there (if so and so light blinks blablabla meaning this and that and so on) then trail back and check what you touched.
ok it works turns out it was a pinched fuel line!
another question, i removed my pair valve covers and installed Dan kyle pair valve covers, was i supposed to take anything out? i saw these two gold valves under the pair valve cover, held in with small philips screws...are they supposed to stay in there?? cause i left them in, and the bike is louder now
i also removed the Evap stuff, and installed a dynojet o2 sensor plug
When I did the PAIR removal, four gold valves with the phillips screw.. I took the screw out and took the valve apart.... Then reinstalled the disassembled valve or just the gasket now...
Only reason I did this is to get an air tight seal around my homemade valve covers.. I didnt wanna spend 30 buck for something that will cost me 2 bucks to make myself.. I also used gasket sealer around the cover/block off plate..
