Honda-SOHC

Went to fill up with 99 juice at end of a run today, tank just on reserve and stupidly got the pumps muddled up and put about a litre of high spec diesel in.

Quickly realise my error and stopped and filled up with 99 E5

Stemmed to run fine on the 10 miles home

Guess it just got well diluted

Lesson learned 😂😂😂

Unsure if I've understood correctly the current adjustment just made Ted.

The left bearing, with retaining ring has only one true position which is "fully" located in it's accompanying architecture.

This is the wheel datum (same on front too) for the rim alignment in the chassis, with all other spacing etc slaved off this installation.  Bearing race fully home and retaining ring fully tightened is the only method, anything else with compromise doesn't take precedent over this procedure.  The other parts and alignment should be looked through for fault if it exists then.

If the primary, LEFT bearing isn't secure in it's location, then the wheel can move across the axle during use  to the detriment of competent running and risk of jamming the wheel in cases of significant movement.

Pretty crap that Honda didn't address the issue with the suppliers Nippon Denso. The metal cover EMC shielding (fitted as way back 1966 to UK CB450K0 Bombers)  was decades ahead of it's time and such a shame that the design wasn't re-engineered to cure the arcing. As I said, I can't see any reason why it can't be re-engineered to work perfectly in the wet. I guess modern silicone mouldings were not around then within the automotive industry.

Those caps were also fitted to Z1's ... wonder if it was the same on that model in the wet. Genuine Z1 metal caps are ££££ I gather. I got all of my Honda ones  cheap because DS had them in his USA warehouse (relatively useless to U.S. customers) but not listed on his UK site.

Watch this space to see if I can solve it.

I have a local source for most O rings

A company called Hayley Group

On a local industrial estate, the Hereford branch are really helpful,

Imperial, metric,fuel resistant etc,

And the bonus, normally a fraction of the cost of NOS,




Take a sample, and the item, like tappet cap ,they will find the size needed

Thank you John
Great tip and advise :-)

One of my favourite rides is from Tyndrum heading east to Killin and then turning off at LixToll towards Aberfeldy, lunch in historic Kenmore by the castle gates and then into Aberfeldy turning right for Crieff over the high road and then back to Tyndrum and Oban..
It's a super ride riding on the hillside road alongside the length of Loch Tay....bet you've done that and more Gareth 😊👍

Yes, that's a lovely route, and the roads for me to get there. Killin and the Falls of Dochart are a good place to stop. 👍 On the nadgery little road on the other side of Loch Tay is the Cave where Monty Python filmed the killer rabbit scene in Holy Grail!
