You need to find someone with high speed internet access, and that will solve all of your problems.
I got through it eventually.
I wouldn't say that solves all my problems though! But it does let me see a little better what will be coming in my HT kit and gives me an idea what to read and ask about.
The after-market billet cylinder heads are expensive (and so is the shipping for me!) so what cheap/free "kitchen table" modifications can be done to improve the HappyTime heads?
1. In the video Fabian focused a lot on the relative cooling efficiency of the different designs of cylinder heads.
I read on MBc about attaching extra home-made cooling fins to the cylinder head; but I've never seen photos or diagram of how this is done. I'm assuming/expecting I would need to grind the edges of the cooling fins flat to allow a good contact area with the bolt-on fins, then drill the home-made fins and the original fins to accept bolts and
somehow simply bolt to the original fins.
Does anyone have experience of making this type of modification, and is it as simple as I'm thinking, and is it actually effective?
2. In the video, Fabian told us that the most common HT straight head has very low compression; but MBc is full of threads about increasing compression so I'm not going to ask about that.
I will have a slant head in the kit that is available here, and in the video Fabian tells us that this is a very high compression head. Bearing in mind what jaguar says in his post #6:
Is there enough material (thickness) in the cylinder head to make significant changes to the slant head's combustion chamber? It appears to be mostly squish band and very little dome, with a tiny or nonexistent blending radius between squish band and dome.
Could the dome be enlarged, reshaped, or the blending radius increased, or the squish angle increased to lower compression? If it is possible, would this be as advantageous as it appears to a layman like me?
