Hey guys,
I was just looking for some insight about the exhaust valves on a 1998 ZR Sno Pro,It was running fine the other day but this morning when I went to go for a ride it doesn't want to pull peak RPM. I thought that the valves might be sticky so I cleaned them, I also cleaned the clutches just to make sure it wasn't a clutching issue. It seamed to make some difference but I don't really think that the problem is completely gone. I'm not sure how to describe what exactly what it is doing but,I would say that it is NOT a bog but more of a flutter at about 7,500-8,000 RPM,It's almost like it is missing but I'm pretty sure it is running on both cylinders,it runs flawlessly on the bottom end and in the mid-range, just on the top end that there is a problem. Any and all input would be great. Thanks
