  • Do NOT use pre-mix 50 to 1 fuel. 20 to 1 is the proper mix. Premium fuel works best for top speed.
Style: Silver 80cc
Well packaged and complete. This kit has the right fuel petcock for the bike. My last 3 orders from other vendors all arrived with dented tanks and sub standard parts. The chain on the last one I bought broke before I even drove a mile. The engine started right up without being choked and it is powerful I am very happy with my purchase. ... show more
