    Yeah, I just looked into those....pretty good deal for 35 bucks total! Although me being me, I think I could buy the #41 chain at TSC and make a better version of the motor mount and use the 36T I bought from dax.

    Maybe next time.

    Why would you mount the motor with lead? you will always have to tighten the motor mounts lol sounds fun going to work or on a joy ride ha .bld.

    I had some pretty substantial vibration at higher rpm's,,I made a front mount out of an 1 1/2" muffler clamp and welded the BGF mounting bracket with three holes in it to the clamp.Had to drill the holes bigger,,but now she is perfectly straight and solid as a rock,,only vibrates a little at WOT,,I dont suggest riding WOT on these chinese motors for much longer than 30 seconds or so,,unless you have a smaller sprocket on back or pulling a grade.Bad motor mounting like drilling a hole in the frame=Vibration!

    Guys, quick question,

    What would you say, if I'd put a silicone glue layer on top of the bar, where the mounts will be mounted?

    A layer of Silicone glue, let it dry, and mount the engine?

    ANYthing that has give in it like rubber or tape or ANYTHING soft will cause MORE vibration, not cure it.
    Mount the engine SOLID and prevent failure.
