On my 07 675. The ex-up valve spazzes out. Every so often the ex-up valve opens and closes repeatedly at a stop before it's been started. I get a "check engine" light every 3rd or 4th startup. It's not stuck, it's spazzing.
On another note, the bike stumbles at 8k every so often. Twist it mid-corner at that RPM and it doesn't do anything...actually it might actually slow down, it's hard to say.
Are these two things related?
What's the best solution for the valve? Should I replace it or just yank it / pin it open? I'll lose torque if I just get rid of it, won't I?
