Plug Change

(1/2) > >>

Brock:
This afternoon, I did the dreaded plug change.

Using the Honda plug spanner, the job isnt too difficult. Easy it isnt, its just fiddly working on the two rear plugs due to space constraints. The only panels to remove are the engine side panels.

The reason for changing the plugs is 18 years of abuse.. and



The old plugs look ok, gap might be a bit big but forgot to measure it before going in the bin.




Old and new plugs..




So all done, and bike still starts and good for another 200000Ks

Plugs will get a burn in tomorrow when I ride with my Son to his work in the morning.


Yes Wombat, the timing belt.....

At least you have a spare engine waiting for me..   o:) o:)

CallMeSteve:
Wow. 200,000k on a set of plugs?  To me that seems amazing.

Brock:
True, the weird thing is,  with a clean up and a re gap they could have gone back in.

There is no sign of wear..

Back in ancient history times, I used to get my modified V8 Falcon dyno tuned. The old plugs used to show significant breakdown on the cro and you could hear the obvious breakdown.  This is with 20000km on the clock.

The plugs looked fine, though...

Brock:
 And they were working well too, always started easily.
