BBR Tuning Racing Series Stage 3 66/80cc 2-Stroke Engine Kit

Building a high performance engine just got a lot easier with the BBR Tuning Stage 3 Performance Engine Kit Package. With this performance package youll get everything you need to get some major power from your motor whenever you hit the throttle. Complete with a high performance head, and NGK spark plug, as well as a high performance carburetor, this engine kit is what you need when your rides need some more power when you hit the throttle.

Compression of a Performance Motor with the Carburetor to Back it Up

With the BBR Tuning High Performance head leading the way, this engine will give you more compression than ever. More compression means an increase in speed and pulling power, so not only will you go faster but those hills and inclines wont give you a problem anymore. And if that wasnt good enough, its tall heat syncs let your engine cool faster, letting your ride longer than ever.

Add to that the High Performance Carburetor, and youve got yourself a speed machine. Its bigger jets will give your engine more fuel, and its air filter will let your carburetor breathe better than ever. Youll definitely need a performance carburetor if youre looking to run a high performance head, and we made sure that this BBR Tuning package had that standard.

The Spark Plug Dream Team Included

What would a performance engine be without a high quality CDI? If youre giving your engine more fuel it needs a better spark than your stock CDI will give it. The Stage 1 CDI included with this package was made for performance, with its high performance wire that offers you better connectivity than ever and a high quality Japanese NGK spark plug cap.

Standard spark plugs cant handle all that performance quite well, so we paired this CDI with an NGK BR5HS spark plug thatll give you the best, most consistent spark youve gotten out for your engine in quite some time.

PLEASE NOTE: Top end assembly required for this engine kit.

Disclosure of accurate engine size: While we have chosen to use the long standing factory branding engine size of “80cc”, the true displacement of the bicycle engine is 66cc. Down through the years China bicycle engine manufactures have advertised their biggest engine as 80cc, therefore we have listed them in the same way on our website. However, the bore and stroke of an 80cc being 47x38mm equals 66cc. Therefore the true displacement of the 80cc bike motor is 66cc. In the west, the volume of a cylinder is calculated by using the formula Volume = Pi x Radius Squared x Stroke. However, in the east the displacement of an engine includes the area of the cylinder head’s combustion chamber as well as the volume of the cylinder. Therein lies a discrepancy between measuring standards by the manufactures in China with those in the United States. However, all “80cc” engine kits on the market today are actually 66cc in displacement size if measuring by US standards.
