Is your motorcycle engine air cooled? If so, did you run into problems 
with the larger expansion/contraction of air cooled's parts?

Can you give more details of exactly what brand and type of coatings you 
used? Were they Jet Hot, or ceramic, or what?

Thanks for your description of your actual experiences with coatings. I'm 
interested in applying them to my 914 someday, so I'm willing to learn of 
other's experiences.
