Was gonna have the tins welded but they assured me the 330 would not make enough power to have failure. (http://forums.trx250r.org/vbulletin_imports/42_6354_2017-04-18_9961.png)

Crankworks is a reputable company.

Post by: udontknowme on September 17, 2015, 10:40:08 PM: some kind of fixture would be necesarry as to avoid any need to hammer on the tins. i dont think honda intended their cranks to be rebuilt but of course it can be done sucessfully with the proper knowledge

I have used Arlan at LED since the late 90's for pretty much everything, very capable for true and weld. I don't think they balance cranks, however. Haven't used Hybrid, but have only heard good things about them.

Most bike shops do not have the type of equipment and or machinist it takes to make this type of tooling. If you have a tool and die shop make it for you, it will probably cost you over $2000.00 for tin can crank tooling.
