I really do appreciate all of the ideas to clean my engine.
I had the day off from work, and I wanted to get it done yesterday.
So I wound up calling Yamaha Cycle Craft in Woodstock, Il.
They were very helpfull. They recommended a product that they use on all the bikes that get traded in, they said it worked great without damaging the finish on the bike.
It is called S100 Total Cycle Cleaner, is the product I used.
It was $14.00 for a quart spray bottle. It did work great, but I do have
to say it smelled familiar, after reading my responses today, I believe it
did smell like Simple Green, That is only an opinion.
Thanks to all who replied,
Steve
