We have a little progress with the engine.
We decided to tear it down to have a look into why the kick starter wasn't working. It turned out that it was installed wrong.
That makes me wonder who's been into this thing!! ??? That's not a mistake FBG would make. :-\
As well, when we had it all apart, we decided to make a drawing of the porting. This will be handy for reference as we proceed down this road. With the cylinder on a flat surface, we rolled a sheet of paper up to open up, pressing on to the cylinder walls. Then we reached into the cylinder with a pencil and shaded the port openings. The pencil does a good job of locating the edges of the ports. Pull the paper out and unroll it and you have a 'map' of your ports for that cylinder. Measurements can now be taken off the paper and compared. It's hard to describe, but easy to do. I'll post a pic of the results.
It's a poor pic, but I hope you get the idea.
As well, the intake side of the cylinders have been milled by FBG so that the Lectron carbs would flow in a short direct line into the cylinders. We were a little concerned that our Mukuni TMX flat-slides might contact the heads, which were not milled. We don't have the new carb boots to mount them yet, so we can't be sure it will be a problem. However, I had a chance to get some time on a milling machine yesterday, so I took it!!
Here are some pics that might shed some light on what I'm refering to.
Hopefully you can see how the heads portrude beyond the machined cylinders:
Here, we're starting the cutting. You can see that the centre cylinder head needs more milled off than the outside cylinder heads:
Now, we're pretty much done:
We're leaving the rest to look like a stock h2. From the front, you'll never know!
We removed nearly 3/4" of material. We should be good now.
I need to take some more pics of the finished product. I'll do that today and post them later.
