Re: Best plug for a 1955 NH

I had three plug failures in a row while using ngk plugs, couple of broken insulators and a broken electrode. I haven’t had a single plug issue since changing to Bosch

Re: Daily Fixing and Riding Diary on a mainly Ariel 2018

I’ve got the wrong dual seat on my VH too. Annoying because I had a spare and sold it because it was taking up space, that one was the right shape!

Re: Morgo plunger pump for singles

Interesting comments, I always knew that running a 9 to 1 piston would give other issues, but for me it’s worth the extra power. I think I might start by diverting the breather to the chain, as I have a ferc, that might work quite nicely. If I’m still not happy then perhaps a good Ariel pump or a Mo...

Re: Morgo plunger pump for singles

Thanks for all the comments, and thanks for the offer John. I’m not sure if I’m over reacting, I do a 10 mile trip each way for work, and I’m dropping oil on the drive, plus the sidestand is well oiled. I do think that the problem is better than it used to be. My main concern is that on longer runs ...

The former it isn’t, it had New piston and rings not long ago and gap is good. I don’t get a good steady stream back up to the oil tank at idl...

Re: Morgo plunger pump for singles

Yeah, I had the engine apart last year and actually removed and refitted the scavenge pipe, and made sure it was fully sealed before refitting.

Tested it too.

Might have to invest in a new oil pump and see if it makes any difference.

Morgo plunger pump for singles

Has anyone fitted a Morgo plunger pump to a single?

If so, is it worth the money for the improvement?

My pump seems to have a weak scavenge, and I have eliminated all other causes.
