So where can I get one made for my fc420
There are no Billet Flywheels available for the Kawasaki FC420V to my knowledge. The displacement is too small and the engine is not competitive in performance non - stock classes. 420cc/25cu. Briggs and Tecumseh will walk the dogs on this engine. It may work well in a governed class. I know of a couple that are quite happy and have had success in J/P with the 420.
CHECK OUT A CUSTOM MACHINE SHOP.
I checked into it for the 540....$1200.00 to $1500.00 for the engineering/CAD/CNC fee's.
There's been "Talk" about someone making them for the 540...but that's just it... "Talk". (I even offered to buy three.)
That about what I paid to have a Billet Rod made for a FB460. And the will only make them in minimum Lot's of 4.
My net cost is $265.00ea in a lot of 4....that's just too darn much. Then again, don't think I have ever seen a stock 460 rod let go. And now the new rules allow you to use OHV's so....it was an expensive learning curve and mistake.
