When I began to examine the layout of the pulleys and engine I was concerned an E-Maax kit would not work or fit. The timing marks and stock crank pulley are very, very close to one another. The design of the Electromaax pulley kits are ingenious in that they simply fit over the main crank for an easy install. This is good and bad for some motors as they make the crank pulley slightly larger.
I shot some photos, took some measurements and I picked up the phone and Called John one of the owners of Electromaax.
