The B33 has got a rumbling engine - and I don't know what's causing it . . . . . yet.

Monday and I pulled the B33 apart - could find no obvious cause for the rumbling noise.

Tuesday and the computer which runs my security cameras decided to fail - ah well it's been running non stop for quite a few years.

Wednesday and I fitted a new idler gear bush in the B33 - the existing one was rather worn. 

Thursday and I set up a dedicated DVR ( Digital Video Recorder ) to monitor the security cameras.

Didn't really do much until Sunday when I put the B33 back together and took it out on a test ride.

The rumbling noise is still there - ah well, I know it isn't the idler gear bush now.  I'll ride it for a while longer and maybe something will show.
