Ok, so for those who don't know, my top end went kaput.  So here's the crazy.  I welded the broken cam back together and added some material to the lobes and reground them.  Now I just gotta set up an old grinder motor as a lathe and polish up the bearings and lobes.  I figure I'll get a few hundred miles out of 'er goin' like crazy with a high lift and reasonable duration.  Since I've got another bike now Suzi's gonna be a NASTY chopper/rat rod anyway, am I crazy to try to rework the cam myself?  I know the reliability won't be there but do ya'll think it will just come apart right away?  I wonder what web does to "hard weld" the lobes..  hmmm...

Absolutely right!  For a moment I almost forgot that I don't try anything!  This could end up fun though, will home modifying a cam work?  We will find out.  I'll jbweld up the gouges in the head and see what happends!  

P.S.  I have no idea AT ALL what I'm doing, even as far as measuring what lift and duration i come up with!  (well, i could maybe measure lift... Should i go for a bit more overlap too?  no, no, I just want really insane low end, pull your arms out insane) So as i update this, remember, NO ONE TRY ANY OF THIS.  It will most likely destroy your motor.  If you really need more power get a carb and cam from Lancer, they're great products. Hmm, if I can find a cheap high pressure bottle somewhere i'll throw nitrous on it too, why the heck not, worst case i'll end up resleeving and buying another head!

Maybe I should have titled this post "the best way to break a savage", or "beating a dead horse for ponie"s?

Having worked as an Engineering Tech in some heavy manufacturing over the years; besides getting to prototype lots of new designs, I was also happily assigned the duty of "destructive testing" of some large equipment. What is it that is so fun about tearing stuff up??? Wait... I know what it was... it was because I wasn't paying for it!!!

no.  go for it.  all out.  


let us know how much torque at the rear wheel it will take to stretch a new cam chain past spec instantly
