Thanks, makes sense about the aluminum cylinder head wear where valves seat! I guess I thought wear would occur between valve stem and rocker tip, or cam and rocker.
Next question...
I exchanged the pistons, buttoned up the engine, reinstalled it, put in new CORRECT plugs (LOL), and ran the bike.
The good news: The bike runs EXACTLY like it did before I stupidly installed the wrong plugs.
The bad news: The bike runs EXACTLY like it did before I stupidly installed the wrong plugs.
I was hoping the initial problem would have somehow gone away. But it continues to bog down. Starting in first gear, when I crack the throttle a bit to get going it seems initially ready to take off for a fraction of a second, but it then seems to bog down and go blahhhh. I run it through the gears, max speed is 50-55. Now I'm a big guy (235#) and I know this is a 250, but I'm assuming the bike can do better than that?
Spark appears very good. Assuming fuel issues. Any ideas, or how would you suggest I troubleshoot?
Thanks in advance!
