Standard replacement gears, or an economical upgrade to add duplex timing gears to your simplex engine.
After turning down many timing sets that have incorrect tooth aligment we now offer this kit. The gears are machined from billet steel and the chain is made in the UK.
When converting from single row chain to dual row the engine front plate must have the main bearing cap screw holes countersunk to clear the crank gear.
