				I thought it needed high test gas.  It is still doing the same thing as before.  Under moderate throttle, sounds like a diesel, but if I ease off, it sounds good the whole rpm range. ????.  Passed the etest with flying colors, new bosh platinum plugs. plenty of power.
			
- 
				Check the timing, are the plugs too hot ??
			
- 
				recommended plugs.   I have not checked timing yet, thought running 92 octane would have fixed that
			
- 
				no, not always :)
			
- 
				I'll check it tomorrow.  What would piston slap sound like?  that would change under power, right?
			
- 
				Sort of a diesel sound, but usually only
 when cold.
- 
				I really notice it when cold.  not so much when warm, but still there.  When I changed to high test gas, I thought I had it licked, but I may have had two different problems.
			
- 
				How many miles on the engine ???
			
- 
				174 km, about 108k miles
			
- 
				ya it could be slap, my pistons do it, and I

				my yamaha virago 1000 did have that on one of the two cylinders, I knew what it was.  This sounds like it's all of them on every stroke.
