Hi folks, I posted this on TOL but is seems to be down for a couple of days so I'm casting the net a bit wider.
While replacing the leaking head gasket I measured the following guide to valve clearances (engine is at 10k KM):
- Inlet guides close to spec in the middle of the guides and double at the ends *(2 thou and 4 thou approx)
- Exhaust guides close to double the spec spec in the middle of the guides and over three times spec at the ends *(4 thou and 7 thou approx)
The valves seemed to hardly have any wear and were almost all spot-on the max dimension in the manual
. The middle exhaust guide was the most worn.
It seems my options are valves and guides are
1. Hyde, (colisbro guides and chrome valves 214N)
2. LPW (colisbro guides and chrome valves? ) or
3. Kibblewhite (Mang. bronze guides and black diamond stainless valves)
4. K-Line liners with new valves (or maybe just with the same valves? ) I know nothing about k-liners though... (except they seem to save the head from possible damage while removing and replacing guides, and the valves should line up well with existing seats.)
From lots of reading online and on this forum it seems any of the three first options are fine and one should aim for about 0.8 to 1 thou clearance (honed).
Does this sound right?
Anyone have experience of K-line liners? what clearance would one do with them?
Considering the bike hardly burned any oil, should I keep going for another few years and leave as is?
Any advice or insight on which way to go would be greatly appreciated.
I plan to NOT use guide oil seals.
I'm doubting the possibility of finding a shop comfortable with brit bikes in switzerland so might have to send to the UK. Any recommendations?
