RTS engine quote

The bill for my engine rebuild will be £850-900 ish. That includes new alpha big end, main bearings, rebore, new piston and rings, valves and springs etc, plus cams and larger inlet valve.  I'd hoped it would be around £750:00 but I suppose the cam and inlet valve modification are worth the extra.  I see no point in doing so much work on the engine, knowing that the head needed sorting out, and not completing the job properly for the sake of £150:00. 

At least the bike will be up to spec apart from the front forks and indicators. We can then fit the indicators and put some oil in the forks and see if any oil leaks and, depending on how fast any leak might be, that will help me decide whether to just keep topping the forks up, or consider having the forks repaired!

Pushrod woe

As usual, click any image to zoom in.

I've taken the inspection cover off and you can see the exhaust push-rod seated tightly under the exhaust rocker arm (at the 3 o'clock position).

At the 10 o'clock position the inlet valve's rocker arm has been separated from its push-rod which is now wedged firmly behind the rocker arm's downward facing semicircular nipple.

This means the inlet valve is jammed open probably resulting in a bent valve stem.  Hope there hasn't been any more damage done.

Replacement engine in

As usual, click any image to zoom in.






The engine in my C15 has been rattling and knocking so it was time for it to come out and get checked over.



I've bought a "new" one from Mike Kilvert (who sold Mark his green C15) and with his help got it in and converted it to 12v electronic ignition.

These are pics from when I went down to his place in Wales and wired up the Pazon kit, and a video of trying to fire it up for the first time while holding my iPad!





These are a few pics Mark took today when he came over to see the bike.



Sadly, it lost power with a clunk today after riding A MILE or so from home - wondering if a valve has failed seeing as there is no compression at the moment.

Happily, Mark was with me and he not only rode back to my house, picked up my car and drove back, but I was sneaky enough to walk really slowly so that I'd only covered about 150m before he pulled up next to me and took over pushing duties. The exercise will do him good - no flies on me!
