I believe I was the one who posted the Honda. I do not have one mounted on my bike. I plan on using a 4-stroke on my next build. I dont know too much about this motor and was asking if anybody has used it.
You cant beat the reliability of a Honda and that is the big reason I would like to use this motor.
I found this motor at northerntool.com
I'm sure they will have this motor else where and maybe cheaper then northern tools but I have not had time to look for a better deal.
