Read some of the advantages of our new revolutionary V-Twin motorcycle engine.
- Gear driven intermeshing gears which allows for positive accurate valve timing at all rpm as there’s no timing or cam chain to stretch, adjust, overthrow or break which can usually lead to total engine failure or injury to the rider.
- By changing from a single to a Twin Cam arrangement, some important and obvious problems were rectified. By altering the configuration of the valve train, high revs were no longer risky business. The four push rods are square as they can be lifters and rocker arms which stiffen up the complete valve train.
- Ever seen a cracked set of cases between the lifter? Well, don’t worry anymore; this major weak spot in all crank case designs has now been addressed. The crank case castings have the tappet block area as part of the crank case assembly, which are then, fully machined to their nostalgic Knuckle looking style which adds additional strength to this once weak area making our big market today. Note how neat the crank case casting meets, with no ugly overhang!
- Tying it all together was another problem that had to be re-engineered to make a good, strong, robust engine combination seal. Are you sick of head and base gasket leaks? For this reason we manufactured our own 7/16” chrome molly cylinder studs and head bolts which eliminates head and base gasket leaks. How can a 3/8” cylinder stud used on a small bore 80 cubic” motor, running 8:1 compression still handle the loading forces of a 147 cubic” engine running 10.5:1 or higher? It can’t! This is why you get head and base gasket leaks, when using 3/8” studs on high output motors, they stretch and move around like chewing gum. You must make it rigid to maintain good stiff clamping action, which will result in more power as you have a controlled squish band between piston and head. This holds true for the cylinder to piston clearance as well.
- Crank case pressure relief. If you can remove crank case pressure under your pistons on the down stroke, the engine will rev a lot easier as no trapped air is trying to stop the pistons from rotating freely on the down stroke. Our unique crank case venting system allows all crank case pressure to exit the crank case assembly without the use of a rotary valve arrangement making this another special design feature.
- Our unique compact gear driven (US patented) design allows our cams to be fitted in one easy process without any shims being required.
- There’s no tappet blocks as our crank cases have them already incorporated on the timing chest side, allowing up to 4 1/2” bores on our cases, adding additional strength and reliability, without the use of extra long pinion shafts.
- No expensive OEM or aftermarket tappet assembles are needed as you can use automotive style tappets which can be purchased at any automotive dealer at a fraction of the price you pay for an Evo unit.
- No breather valve assembly, which can be expensive and unreliable, as they can gall out the breather compartment, making for an expensive repair bill. Our unique system doesn’t require a breather assembly as we’ve redesigned the breather system to work more efficiently without the use of a rotary valve.
- No pinion or cam gears are required, as they’re included in the price of the crank case and timing chest kit.
- By changing from a single to a Twin Cam configuration additional service life has now been granted to lifter blocks, tappet assemblies, valves, valve guides, push rods and rocker arms and shafts.
- Redesigned Conrods, crankcases, and cylinder deck heights have allowed us to use additional skirt length on pistons (especially the rear), which maintain stability in the cylinder bores adding for better ring seal and piston life.
All motors come with a Dyna 2000 I programmable ignition system and either a 48 mm. mikuni or a S & S super G series carburettor. We bench run all v twin motorcycle engines for quality control purposes before they are shipped out to our customers, so they know when they get a Renegade motorcycle engine it is ready to go. Because our engine is 15mm taller than a stock Evo your stock frame needs modification. |
