Honda-SOHC

Be interesting to see how you get on with it - looks great bit of kit - how did I ever manage without one in the past?

Please let us know how effective it is Mike when it arrives and you do the magic.

You are not alone my 400 has the nut on the left hand side.

In the Honda Parts List it is shown with the nut on the left hand side.
Might be it's been shifted to the right side so the silencer is not in the way.

Hello,
I bought a pair of coils from EBay for £37! They’re bound not to work!
I’ve just fitted them. They’re working fine so far after an ‘extensive’ 25 mile test.
The only problem is (as someone else here stated) the mounting holes are 90mm apart and the  standard fitting on my 550k3 is 100mm apart so you need to make up two little steel brackets. Measurements, 11mm wide, 28mm long with two 6.5mm holes with centres 10mm apart and 9mm from each end. Also as they have male spade connectors you have to make up 4 wires (2x female spade to male bullet black with white stripe and 2x female spade to female bullet one blue and one yellow). They need to be about 250mm long. I don’t think the coil connections are polarised so I just wired them the same way as each other.  I suppose we’ll see how long they last.
I was also quite pleased I did this as the yellow wire connection just fell apart and was due to fail. Good luck with it.

Is the primary resistance quoted?

A link to the actual item would help.

Might be the  bidders saw it in the flesh and the photos were very flattering.
Auction prices are sometimes about extremes in either direction rather than true value especially as there was no reserve set and the family just wanted to move it on quickly.



This 550 only fetched £1000 - I'ne no idea if this was cheap or is that all they fetch unrestored.

Back in the 1960/70s many banks charged businesses when you banked cash. The cost of handling cash was rolled up into the overall  bank charges to the business.

My late father used to tell me that when he was in the car trade back then most private purchases paid in cash with company purchases being paid  using cheques. He put the rapid expansion of private car ownership to the availability of hire purchase and credit sale agreements that reduced cash handling as finance companies often paid by cheque.

In the last three plus decades we take free personal  banking as the norm. Our "free" banking is in reality subsidised by different forms of fees attached to our transactions.

A local Chinese Takeaway has become cash only quite recently, truth be told cash can be a way to avoid paying income tax.
When I used to sell cars to Farmers they would want you to reduce the invoice price and pay the difference in cash.(Floor board/matress money from selling eggs etc privately) My late boss always like some cash of this type - no surprise when he was paying 95p in the pound including surtax.

Are those handlebars original fitting they look somewhat US style ones?

Both my 400 & 500 needle clip is in the middle position 3 counting from either end.
