Any thoughts on the new 4 stroke kit offered by Gasbike.net? http://www.gasbike.net/products/79cc-monster-80-bike-engine-kit-4-stroke I have been waiting to get another 4 stroke, after my 4G crapped out and I got tired of belt issues, I just want something reliable yet cheap for my leisure. What would I have to do additionally to get this kit running? Can I use the stock muffler? Stock gas tank or buy one to mount above? I have had great luck and put many many many miles on my china girl, but I want something a bit more quiet Thanks for any replies!
