501 Cam Lobe Completely Worn Away

OK, so if you’ve been following the thread below you’ll know that after a small crash at local mx track on my trusty FE 501 02, the shift rail & shift quadrant plates got jammed (don’t think it was as a result of the crash directly).

Anyway, other than that, bike been running fine.

As a result of being a **** & fiddling with all the cogs I felt the need to have the rocker cover off to check the timing positions...

At first I thought there were 2 types of rocker roller bearings – a flat type & a radiused type & that the radiused type has chipped away the female wall edges in the cam shaft lobe...(I did say **** didn’t I??).

Have you ever seen this much wear on a running engine before??

Had noticed a small (really) amount of sliver coloured filings last oil change but nothing to get too excited about.

I guess the big question is; as an 02 – 14 year old motor, if I’m going to replace the cam, what else should I do at the same time.... I’ve kind of been thinking the mains are due for a change but this is all getting a bit major & perhaps a refurbed engine would be a better way to go??

Or...better the devil you know...

Cheers Zaga - meant to PM you after our last discussion.
Experience - umm - I like to give things a go - but generally it's 1st time for everything and you don't find out what you've done wrong till you do it...like with the other thread above..the manuals don't tell you whats gone before - ie in the transmission section it doesn't mention anything about aligning the dots on the primary & idle drives (timing) when fitting the clutch cage. However, this is covered earlier in the re-fitting of the primary & idle drive sections (which I wasn't doing so didn't look at!!).
Why don't you think changing the engine is the way to go?? A full rebuild will cost more than the bike is worth if I get someone to do it. If I do it it may never run again...lol

Hi Zaga - not what it's worth but how much do I have.
I'm very attached top my berg and may even undertake a complete re-build including frame re powder coat etc but that may take some time & what to do in the meantime.

Big Berg - as my boy does mx - I'm pretty hot with oil filters / changes & air box cleaning etc so none the wiser as to why. (Perhaps not so good with the valve adjustments & bearing checks??). Interesting though re the stellite coating.

Ummm..will probably do that...but as a project for me...fun but will take a long time or pay someone??

But as you say, I can't believe that the fine tolerances that these temperamental birds work on, that it even ran, and in fact was running really nicely??
