Please read entire description for all details.

Runwell PK80’s are the real deal! 40mm Stroke, short rod, type A piston, M8 mounting studs, and Allen-head hardware all around – not to mention their well balanced crank that’s machined to near perfection and is oh-so much fatter than the others!

No marking or stamp on the con-rod. This ensures it’s a REAL RunWell motor, and you know you’re getting the best!

You get:

• Complete RunWell motor 32mm intake (some assembly required)

• OZ Super Magneto

• Seal Retainer (magneto side)

• .5mm Copper Head Gasket

• Motor-Mounted Spring Chain Tensioner.


Engine is not assembled. See pic #2 for reference on how you’ll revive the motor. The cylinder studs, cylinder, piston, head, etc will need to be installed by you.

Spring tensioner needs assembly. Installing this tensioner is very easy, but it will cause less clearance for the left side pedal crank of the bike. You may need to grind down the crank on that side – or you can buy a wide crank set.

These engines are not ported, but they are among the most powerful stock motors available.
