4 of 5 Needs Work to Fit Older AV7 Case and Cylinder Friday, September 5, 2014
taco eater : Bruce Wilson from Washington, UT United States  
Installed in a 1963 AV7 case and it wouldn't turn at all as the crank lobes were rubbing on the engine case. Used a grinder to make more room for the crank and then found that the connecting rod was wider than stock rod and hit the cylinder skirt on the up swing. Used the grinder to narrow the connecting rod to stock size. Lots of work but in the end it works great.

2 of 5 Vibrates way to much! Tuesday, March 26, 2013
taco eater : Deron Miller from San Diego, CA United States  
Installed this crank in my stock engine with the stock piston and it would vibrate my teeth out after only a short ride.

I checked it for run-out and it was fine. The only thing I could think of since it's a "full circle" crank and the stock crank is not. That it needed a different weighted piston to balance the assembly correctly.

I took it out and sent it back. Benji was great about dealing with me on this. I got a stock crank from Benji and the engine was in much better balance. Not as good as I would of liked, but at least the bike was now ride-able.

2 of 5 Crank needs machining to fit AV10 cases Tuesday, May 1, 2012
taco eater : Max SS from Canada  
Crankshaft web to axle radii machined way too big from the factory. If you try to press the bearings without machining excess material, there will be about 0.040” gap between web bearing seating surface and the face of the bearing. There is no way to assemble AV10 cases with bearings seating like that. I had to machine the crank in order to get the bearings seated right. Not sure, how it works with AV7.
