Just out of curiosity, what further damage do you think may occur by continuing to ride with that partially stuck/sticky exhaust valve?



I don't know if there is enough headspace above the pistons to accommodate the stuck valve but I suspect there is or we would be hearing reports of destroyed valves, pistons, etc. so I doubt any serious damage would occur.

In the end the valve sticks so much that in reality you will be riding on one cylinder; the other one just goes along for the ride.

The bike is almost impossible to ride like this.

48 degrees when I road to work this morning will be 68 degrees on the ride home.

I'll stay were I am. That's too warm to keep the beer cold.

Re:Where's Pop Rivet? 5 Years, 6 Months ago  
I keep talking about a friend of mine who's been wrestling the "sticky valve" problem because he's been through just about all the recommendations I've seen posted here and on the RSR. He reamed the valve guides, cleaned the heads and valve stems, put in Orient Express valve springs and thought he was good to go. Bike started acting up again after a few thousand miles.

Latest thing he did was to pull just the rear cylinder head. He had noticed that the valve seats on the RS are really thin. He ground the valve seats to get a really good seal and put it all back together. Says the bike (2005 Silverado) is running better now than ever. Wonder if those valve seats are just too thin?

Yes, that seems to be the 'new' theory. The 06 seats on the valves are different. I believe they have a different angle and much wider than the 05. The larger seat would improve heat dissipation whereas, depending on the angle, flow may be improve which would cause less buildup of carbon.
