ATVridinMaNiAc Posted November 3, 2012 Report Share Posted November 3, 2012 Dad tore down his banshee and saw that the rod did some damage to the case when it went out, he took alot of the damage out with a wiz wheel already but just curious if the minor scoring would affect anything at all? i doubt it really would, were gonna try to clean it up a little more also, thanks.

sheerider11 Posted November 3, 2012 Report Share Posted November 3, 2012 It's to the point. I almost think that's factory because I see it so often Quote Link to comment Share on other sites More sharing options...
ATVridinMaNiAc Posted November 3, 2012 Author Report Share Posted November 3, 2012 Yea i figured it wouldnt be shit to worry about but i wanted to ask and hear people chime in just in case, im sure it technically throws off a few volume measurements and other things specially compared to the other side but i would guess it shouldnt actually effect anything.

jbooker82 Posted November 4, 2012 Report Share Posted November 4, 2012 If you would have ran it a little longer you would have only had to trench one side for a 10 mill crank Quote Link to comment Share on other sites More sharing options...
spurdy Posted November 4, 2012 Report Share Posted November 4, 2012 The volume of the crankcase chamber is irrelevant anyway. You're only moving the volume of the displacement of the cylinder movement. Any roughness in the crankcase will cause a little turbulance helping to keep the fuel atomized.

mike0chek Posted November 4, 2012 Report Share Posted November 4, 2012 ive seen that type of wear in most of my teardown's. Quote Link to comment Share on other sites More sharing options...

oldskool Posted November 4, 2012 Report Share Posted November 4, 2012 I wish I had been that lucky. Can you tell me if the half round circlips at crank and tranny assembly only go in lower case. In the service manual I don't see clips at top half of case. Thanks Quote Link to comment Share on other sites More sharing options...
spurdy Posted November 4, 2012 Report Share Posted November 4, 2012 They can go in either side. You only need one to maintian bearing position. SP Quote Link to comment Share on other sites More sharing options...

spurdy Posted November 4, 2012 Report Share Posted November 4, 2012 serious? Where do you come up with this stuff? I'd try to explain it to you but I'd just get frustrated.....again. Same reason the intake isn't polished. SP Quote Link to comment Share on other sites More sharing options...
VR350 Posted November 4, 2012 Report Share Posted November 4, 2012 Crankcase volume does affect the performance of a motor. This little bit of damage won't hurt anything at all. Quote Link to comment Share on other sites More sharing options...
spurdy Posted November 4, 2012 Report Share Posted November 4, 2012 Crankcase volume does affect the performance of a motor. This little bit of damage won't hurt anything at all. That's what I was trying to say without going into too much detail. The volume "pushed" from the downward motion of the piston "pulled" into the cylinder from the increase volume of the cylinder chamber is relative the the displacement volume of the cylinder. And this little bit of damage could be erased by roughing up the surface area of the crankcase which would assist in atomization of the fuel especially if the cases are port matched to eliminate heavy turbuance and increase flow.
