Bantam John, who was also known as Sheffield classic motorcycles or similar, had some stainless flat blanks some years ago. I bought a pair from him in about 2013, even then he was reluctant to profile them, and he charged me a fortune!

I’m not sure if he’s still going, but it might be a lead for ...

Hi Martin,

From your photo, you have a stud with a domed nut on it immediately below the oil lines as the photo is taken.

Usually you will have a small banjo union which then has a copper pipe leading up to the spider rocker feed on the head (why I call it a spider, I don’t know, it only has 4 ...

Hi Martin,

I suspect your carbonisation problem will be partially caused by the rocket feed, which is on the pressure side of the oil pump (unless it’s been modified already). You can find this out for sure by tracing the oil pipe from the rockers and seeing if it joins the crankcase on a small ...

I have a very similar experience to Colin. I fitted one to my square four and found that the backing plate was shorting out on the magneto and kept blowing the fuse as a result. I didn’t bother to contact them I just filed out the backing plate to have sufficient clearance and since then it’s been ...

I run semi fluid grease in both of my bikes with GB boxes, precisely because I was sick of oil leaking out of the Speedo drive. VH has done thousands of miles like that so works for me. I don’t use the level plug, I just syringe it in and occasionally squirt some oil from the can in through the ...

I did a compression test on my ‘48 4G last year, when I was having some running issues and needed to rule compression out. Using a good quality tester I borrowed from work and with WOT I was a pretty even 95psi on all 4, so I’d say your figure on a MK2 with higher compression pistons is in the right ...

I don’t need to, he did that too!

Well I’d delayed sending off the cases due to being busy with life in general, I finally sent them off last week to the welder. Imagine my surprise when I got a message on Monday to say they were done and they arrived back through the door this morning. That’s a one week lead time and a cracking job ...

This would make a huge amount of sense. I had been wondering what was done to account for the different mainshaft on the FERC models.

Could it be that the factory simply found that the FH sprocket fitted nicely, and no further work was required?

I saw one for sale on eBay a few years ago. Clearly people knew what it was because the final price was gigantic, I think between £2-300.

It wouldn’t surprise me if Draganfly sell a pattern one.
