Just joined the forum & posted on the Introduce Yourself thread, so I guess it's OK to ask a few questions here. I have a 1998 black classic Whizzer with a defunct WC1 motor that will soon become upgraded. After riding the bike for past 2 months with all restrictors removed, the valve seats evidently loosened up, even though I wasn't pushing it all that much (30-35mph, and mostly under 30). It ran beautifully until the other day when it started missing, stalling and losing power. I thought it was ignition, and replaced the CDI module and when that didn't work, I started to order a new coil, but after reading Quentin Guenther's wealth of information posted here, I realized what was wrong. Pulled the head and intake seat was pushed up about 1/4 inch. Using the valves as guides I whacked the seats back into place with a hammer (gently) and then cleaned and lapped the valves. After this high-tech treatment I was able to get an additional 3 minutes of full power before she crapped out. Let it cool 5 minutes, and it was up and running for maybe another minute. Ordered new NE5 upgrade kit yesterday! My questions are:
1. Is the old WC1 cylinder repairable or just scrap metal? Could new valve seats be pressed back in?
2. Are there any parts on the WC1 (cylinder,carb,valves/valve cover etc. that can be saved as spares for the NE5?
3. Is it OK to open up the restrictor plate on the NE5 and run it with the old WC1 exhaust baffle or a completely open pipe? I don't want to burn it up again! Sorry about the long post. Thanks in advance. Squeakit
