When building engines with longer conrods, you need packing plates. This sometimes means that when fitting the cylinder cowling, you can find it doesn’t fit properly and it will under stress, which can lead to them cracking from their connections leading to the air cooling being jeopardised.
To help combat this Darrell Taylor of Taylor Tuning has made spacers of different sizes.
In the pictures, you’ll see before and after where I have the 3mm packer fitted to my 230 engine. There’s a gap before fitting the spacer.
