Thank you making a video that does not have stupid music and droning dialogue. It just gets down to business. In the same league as newyorkshireworkshop.

As a motorcycle mechanic for 20 years I have rebuilt many cranks this way including the Hondas. Different technique but the same result good job👍

Honda's version of crankcase stuffers which is what we called 'em back in the 60's and 70's. Been rebuilding cranks for decades.

Great job re-trueing the crankshaft! This video is inspiring me to find a used but decent crankshaft to try rebuilding and re-truing it. (In order to really figure this kind of stuff out you’ve got to do it, right?) Well done sir as always! 👍

Bravo Paul 👍👍👍🙂

Why was there extra metal on the crankshaft. My first taught was delete it lol.

No le afecta quitarle el recubrimiento ?

Do you have a link with bike running ?

Does that sheet metal take off not affect the horsepower or the quality of the engine?? I have a CR250 from 87 an needs rod remplacment so i don't know if I need to take those covers of..

Yes it will effect your bottom end power because of a lower crankcase pressure that caused by removing the cover, But your engine will run cooler at high rpm though.

thanks I think I'll just buy a new one now

All your videos are really good, but to run that crank with no stuffers is not good at all, the bike will loose all low end response, Honda builds that crank so it's light, and the tin can takes up the excess volume.

Are those plates to stop turbulence rather than to add volume as this looks like an afterthought on Honda's part which I would not think likely, easier to machine the cases smaller, what do you think?

@@evaork3746 No it cant be full round. It is offset to counter balance the weight of the rod and piston. The metal on the outside is to take up volume inside the crankcase increasing your primary compression. While this may run. You are giving up top end generally from a lower primary compression. Many builders will fill the crankcase with epoxy to increase primary compression which generally increases your top end. There is so much science to this that it cant be explained in youtube comments.

Pro-X rod. They supply silver plated flat cage bearings as well - 22.243117F. The covers would have been to reduce windage. The secondary effect would have been a reduction in crankcase volume. Removing it will probably improve thrust washer lubrication which it looked like they need. The increased windage will reduce performance and the increased crankcase volume will probably improve on-the-pipe performance. Maybe.

@Baboner984

Loss of performance due to the increased free volume in the crankcase. If Honda made that covers on the crankshaft there is a reason.

Only OLD Villiers and the like used crankcase compression to transfer mixture. Modern engines at anything over cranking revs, and particularly on-the-pipe, use resonance. Increased crankcase volume will likely increase power, especially if other mods are done to take advantage of the extra volume.
