Yes he is.
Once I have built the engine and have got it running correct and synchronised the carbs,
It’s off to mick abbey to make the exhausts and set the carbaration up on the dyno.
Well, Mick knows his onions so at this stage and on paper, it looks like it should be a stonking motor...

Look forward to reading about the updates..

E3 plugs ,aren’t they the plugs with the fancy electrodes, bit like marine plugs? Looks like everything on your sparks from generation, timing, connection and firing will be spot on. Looking forward to hearing how its going.

Hi Steve,
Been running mine with all those parts for over 4 years now, never missed a beat, never fouled a plug in all that time, and had quite a few blasts on Mick Abbeys dyno.
Cheers

I didnt spot the electrical wizardry you had employed in your build Bernie. I guess I looked more at the finishing and those lovely Lomas pipes.

Now got my 34 mil Stuffers for the vforce3 👍picture shows the big difference between the std 28 mil ones. Image I’ve also had the air box lid modified by Bernie as well. Image As I will be running 34 mil carbs Bernie also sourced correct air box to carb rubbers not trying to stretch 28s lol as you can see big Image and to compare the std ones . Image. And thanks to Doug I got a metal air filter support as well. Image. The carbs will be stripped and rebuilt by Martin to make sure everything is spot on Image. Image

I'm not sure whether V-Force actually list those stuffers, Scooble, but BDK certainly do!
