Hi Everybody,
I'm looking for advice/opinions on modifying the engine on my Whizzer NER. I bought the bike in spring of 1999 and as of now she is still not tiltled to run on the road. That's another story! In the meantime in the Whizzer world a lot has happened....Whizzer USA no longer imports the NER, let alone any Whizzer...NE5 parts are drying up, in particular the cylinder and finally, after a few miles on the road it is now known that the NER had some iffy engineering; a problematic cylinder assy with a steel "cassette" for the valves, inadequate cooling fin height for the cylinder head....**** thinwall tires.....Inferior metallrurgy (Thank You Taiwan)....CVT drive that slowed the bike compared to the NE5. My goal for my NER is to look at each area of the bike to see if it can be improved for better reliability. I think it's doable, it's a matter of parts availabilty and or money in some areas. Here's my questions:
1. Has anyone used or considered using Jet Hot coatings or an equivilant for coating the cylinder head/cylinder barrel and exhaust pipe to cut down on the high temps of the Whizzer engine?
2. Has anyone used or considered using Jet Hot coatings or an equivilant dry film anti-friction coating for the piston dome/piston skirt and the cam/cam gear/gear train and lifters?
3. In replacing the NER cylinder head and block, what are your opinions on the Woodstock Whizzer cast iron cylinder with the Westman cylinder head versus trying to locate an NE5 cylinder and head. Would a Westman cylinder and head treated with the Jet Hot ceramic coating be a viable thing to do and would it cut down the expected heat soak from the cast iron cylinder?
4. Did the NE5 cylinder block threaded heads have the problem of stripping out due to poor heat treatment of the aluminum casting?
5. When I've run my NER for short periods in the garage, the heat buildup is incredible. That's what got me into thinking about the Jet Hot treatment. Since the Whizzer has no pressure-fed oil system combined with an 8 ounce oil reservoir it's not suprising to me that the Whizzer runs so hot.
Well, I suppose that's enough for now...I'd appreciate any and all input on this, especially from the Whizzer folks with the extensive experience in the bikes' quirks. As of now, I purchased and installed Quentons' mushroom lifters and had him mill the cylinder head (2009) but looking at that goofy valve cassete held in by a socket bolt got me into thinking that there has to be a better way.
Thanks,
Mike
