    Haven't used it but they do make a very good product with a lot of testing before they release it.

    Being a former employee I must say if you want a long lasting big power sonic cruiser pull the trigger.You won't be disappointed.The character of a Zippers engine is free revving with a killer midrange and top end to die for.If you don't have them do the install be sure your mechanic knows his stuff.Call them and talk to a sales rep they're very knowledgeable.

    Hey Fisher Thanks.I made a typo and its the 103" I am now hearing the gripes about the stock 96" crank?I am looking for some good info for this problem as well.If I have to pull the motor all the way down for this "Trueness"I think I would rather build another motor and build a bobber.Thanks ya'll for the info,Mike

    Your '07 is probably fine.But you don't need to pull it down to check.Pull the exhaust,cam cover and do a runout on the pinion shaft.That'll tell you a lot.
