I rode my rev3 yesterday and it ran very poorly.
It was like the engine hadn't fully warmed up and there was a general lack of power just the same as when you first start it before the engine has warmed up.
I have recently repacked the exhaust muffler, new spark plug, engine oil change, and new thermostat.
Is there any way any of this could effect the running of it resulting in this poor running problem?
Any suggestions would be worth a try.
Thanks
