Lazy cam follower

Looks like the source of all the tapping was a lazy cam follower.
All the valve train gear is in remarkably great condition given the age/mileage of the engine.

We've checked all the rockers, lifters, push rods valve seats, guide and the camshaft and nothing is overly worn. Decided to clean out and refit the followers.

Restarted it last night - god awful clatter for about 10 seconds then the followers pumped up with oil pressure and things were much better. I used a mechanics stethoscope to have a listen to the rocker covers and there's a massive difference. The engine is quite and all I can hear is the faint (normal) tapping of the valves. Oil pressure is much better now too. There is still a minor tapping which I think is an exhaust manifold - got a set on order.

The reassembly went well with the exception of one water hose that was a bit loose causing a minor water leak.

Tonight I'm going to replace the oil pressure sender and do a full oil change. Also going to try and get the motorbike up and running and ready for sale.

Broken bonnet mount

I noticed when fitting my alternator that the passenger side bonnet mounting was broken. I have been wondering why it was rubbing so badly.

I purchased a pot of P40 Isofix and re-fibreglassed the mount back into place.

It's a two person job getting the bonnet off. Pretty simple as it's held in place by 4 allen bolts.

Here she is with her bonnet off.


I took the time to paint the exhaust manifolds with Very High temperature matt black paint whilst I had good access. A few more inaccessible bits to do - but need to get under the car for those. (note shinny new alternator and poly vee belt)
