This is the updated Team Line .21 B7 Pro Competition Off-Road Engine from Werks Racing. The New B7 Pro features an all new crankcase design along with a long stroke piston/sleeve and turbo combustion chamber. The crankshaft is of a new design as well, in addition to new timing, the inlet has been lightened and ramped with an epoxy filler. The face of the crank of course is fluted and has been balanced with a tungsten insert. We haven't stopped there, the new 2-stage carburetor has a smaller 9mm slide that improves air velocity just below the venturi insert.
The engine uses a slightly revised lightened, low CG head design like that which was found on the existing B7. For the rest the B7-Pro only shares the carb pinch bolt, collett, exhaust gasket and head screws with the existing engine....it's all new baby! More torque, more mid range, more top end, not more fuel consumption! The motor screams and ironically it uses less fuel than the old engine. Based on testing this will be one of the fastest motors on the market! So if you really want to see what "Speed" is like, get your hands on the new Werks Racing Team Line B7 Pro!
All components are hand matched at the factory for the tightest possible tolerances guaranteeing the best possible performance.
New Stiffer Case Design
It still maintains the look of the old case but with an additional stiffening rib that wraps from the base of the carb to the exhaust port. This is to control expansion of the case around the sleeve which allows us to maintain tighter tolerances between the case/sleeve fit. This is critical to always ensuring that under expansion (from heat) your sleeve always maintains a perfectly cylindrical shape. Case also receives a black coating.
New Piston/Sleeve
The piston is completely new and lightened plus it is now a domed piston design for increased compression.
While the sleeve maintains the B7's namesake 7 port configuration it is completely new. Revised timing and a new smaller bore (long stroke design!). Tear dropped transfer ports & chamfered lower sleeve for improved fuel flow.
New Carburetor Design
It's now a 2 needle with a fixed mid-range. Stillcomposite with replaceable reducers (8mm stock). Idle screw is mounted on the top so no exhaust in the eyes. New taper to the needles. Reduced diameter of the slide results in improved derivability and quicker response to throttle inputs.
New Long Stroke Crankshaft
Crank has also got almost everything done to it that you can possibly do including.... drilled (lightened), epoxy stuffed induction ramp and tungsten balancing weights! (Basically it similar to that of a Speed engine)
