      Mini Moto, Quad, Motard, Dirt Bike 50cc Race Engine RedFUN:BIKESMini Moto, Quad, Motard, Dirt Bike 50cc Race Engine (Please note this does not fit Funbikes Mini Quad) An uprated performance orientated version of the standard 49cc mini moto engine. Featuring multiple upgrades from the standard engine which include full circle balanced crank, which generates higher torque and smoother running, ported high compression cylinder with aggressively vented cylinder head for improved cooling, bigger fuel flow carburettor, and performance air filter. The engine also features a substantial metal pull start, heavy duty clutch housing fitted with 6 tooth pinion and stronger heavy duty clutch. The pull start, clutch housing and air filter have all been colour matched with the cylinder head. The engine revs approx. 3000 rpm higher than a standard engine, right up to 12000 RPM. A standard mini moto engine is approx. 2.5 HP. This one is nearer 4 HP. The biggest increase isn't top speed, though it is slightly faster. The real noticeable difference is low down power and acceleration, which is referred to as torque. So this is a high performance high torque engine. Being a race product we are unable to offer any warranty on this item. The engine will vibrate and you will therefore need to check all fixings for tightness before each use. We also advise as with all mini moto based products that users should have, or know someone with mechanically knowledge as constant maintenance is required. For some mini quads you will have to fit the standard black box air filter as there maybe not enough frame clearance. If you're looking to replace or upgrade your existing mini moto engine, then this is a great purchase for you PC343977
