OK, I know I’ve been tardy about posting lately, but not very much has been going on. However, I’ve been re-invigorated by a trip up to the Autosport International show this week, along with Adrian. I didn’t actually buy anything but it was great looking at all the bits and we bumped into loads of fellow RGBers.

So, it was time for another race. I decided that I could take the weekend off finishing my thesis (which I have since finished, yay!) and make the loooong drive to Pembrey for two RGB races. Problem with Pembrey is that it’s a long way and it has a bad habit of raining. Rain as in absolutely pouring down, not that sort of pathetic English rain but the full-on Welsh variety.
I’m still in a bit of a quandary about what happened to the chain and sprockets. I spent a while measuring it as accurately as I could tell and I think the driven sprocket was translated about 0.9mm to the right of where it should be and was at an angle of 0.3° to the drive sprocket. I’m not an expert at chains but that doesn’t sound horrendous.
Hmm, I think I’ve found a bit of a problem, which might just explain the problems I’ve been having with the new engine.
After the first outing at Snetterton I’d noticed that the chain had needed adjusting quite a lot. That seemed a bit odd but I didn’t think too much about it. However, I’d noticed that the same thing applied after the Silverstone race. At first I was wondering why the chain was stretching so much, or perhaps the sprocket was moving slightly. However, I think I’ve found the problem…
So, on with the tale of the engine upgrade.
As a couple of people suggested to me, I made a support for the standard-sump equipped engine as in the photo here. This allowed me to support the engine in position to see what I was going to have to do to make some engine mounts.
Note that I’m using a motor sport magazine to get the support at the right height.
