Honda-SOHC

Hi Ash

This is what he sent back so if you Know what he is on about can you have anther look at the sprocket please to give him the more info.

Hi, You have not said what chain pitch you have but I assume it is 530. The 4 mounting bolt holes distance apart (known as the p.c.d.) is taken from the centres of the bolt holes.
I make it 74mm centre hole as there is nothing listed with 73.7mm. The p.c.d. at 110mm with 10mm bolt holes.

Is the sprocket flat on both sides or a recessed ring on the inner face? I think it might be 280 sprocket type but I now need to check to see if this is still available.
 

Normally a small arrow on the crown

With the size

Looks like a small triangle

I stock the Genuine Honda oil pressure switch, it's £29.99 - 10% discount + whatever the post cost to you, which isn't much.

Hey everyone! I finally got to it.

I simply had the bike idle while the left cover plate was off to see where it was leaking from.
Surprise surprise it was the oil pressure switch again, from the switch to pump body thread AND from the eyelet screw thread on the switch itself,.
Guess I'm up for another switch, although I am not sure about which one to pick anymore.
I chose a new switch that is made today for several japanese/ asian automotive manufacturers. Honda lists it as the replacement reference for the original that was used in their 70's UJMs.
Those new switches are around 4 euros a piece, so it felt like a no brainer compared to the 40 - 70 euros originals on Ebay.
Now with the performance from the one  bought, I'm having second thought. Because the cherry on top of the crap cake is that the oil light came on like a minute or 2 after the bike was turned off.
Doesnt look like a quick switch to me, unless the oil does stay pressured well after the pump stop turning ()

Looking forward to hearing from you all. I hope you guys get good weather!

P.S. : I found out that a motorcycle that won't turn over could be in need for petrol. Whou would've thought? I was already considering taking off my carbs for a clean 

Ted, don't use them on a warm engine. Could get messy! 🤣
