How's your 618/670 running?

Hey Guys,

Haven't made as much progress as I would have liked. Went to Costa Rica for 10 days. Wife graduated College just prior to that and yard work for the party was necessary. Needless to say I got side tracked for about 2 weeks.
Today I pick up the engine hoist to help me plant the new engine. I almost dropped the 618, twice, when I was trying to lift it myself. Needless to say I don't want that to happen at all! I'll start mounting the 670 on the KF this week.



I was able to 'fit' the exhaust with the 618 and get everything shimmed to have it fit, snug, but very nicely.


I've attached pics of the 618 mounted and the cowl modification I needed to do to have it fit in the cowling. I think it turned out very well.





Also you can see the head that Rotax Rick modified for dual plugs. This is the stock 670 head that has the recirculator just like the Blue Head but provides a bit more compression. Rick estimates it bumps the 670 up to 95hp!
