greetings from gold coast australia

Just like bring to your attention,the potential hazard those nice shiny chrome mufflers are, had a slow speed spill,nasty burn to the leg! some sort of insulated wrap would be good.i just made a 36t sprocket out of a bmx front cog fixes 67cc runs smooth like my48cc but higher top speed,its had the porting/piston mods etc,cruises good just off idle.

Welcome to the forum

Many wrap there muffler with header/ exhaust wrap

Welcome Gav good seeing another Aussie, you'll find everyone is really cool here..
