Quadard Performance Engine - Stage 1Click to enlarge Click the images below for alternate views Quadard Performance Engine - Stage 1. This starts in our workshop as a standard 49cc engine. We then add our High Performance Cylinder Head, then advance the engine firing timing. The engine then has so much more compression that we have had to add an alloy pull start complete with alloy cog. This revs at least 2500 rpm higher than the standard factory spec engines, and produces more power throughout the rev range. (Sold as a competition unit - must be run-in for 3 tanks of fuel at 25-1. No warranty implied or given on racing products) Total cost fully built and TESTED priory to delivery. £119.99SpecificationsProduct Code: Quadard Performance Engine - Stage 1Manufacturer: FunBikesProduct Weight: 0Stock Quantity - 0
