Was looking to install a gas kit on my Jamis Mens mountain bike. I have seen a lot of different sites selling kits. I was looking for guidance on motor and kit selections. I have seen several different options and I think I want to do a chain drive rather than traction. Also think that I would like to do a 4 stroke engine (prefer a Honda) but would settle for a reasonable quality similar engine that I could FIND PARTS FOR IF EVER NEEDED. I am guessing about 49cc in size. I saw a 'Flying horse kit and have been having trouble finding the Titan kit but that looked decent as well?? So, what would you recommend and WHO to get it from with best price, quality, and replacement parts......... Thanks for any and all info provided!!! BTW Iam in NJ so I think 49cc is the max for a bicycle kit?
