We use a digital pyrometer on race bikes just to see what's going on and rarely see 200 on most of the fins. Around the exhaust it can reach 240 or so but not much more because it's a huge heat sink shedding heat.
If your head reached 600 on the outside, I'm sure it would have melted on the inside.
Put another way, if it works on an HD putting along so slow there's no air to cool it, then it should be fine on a cafe race 350....
It has been a while since an update, but I have not stopped working! I have been quite busy, but I can only work small amounts of time at a time. I got in the shop today and finished several things I had started.
First up is the polishing of the fork lowers. I spent a good amount of time working on them to get all the piting out and remove the casting marks. I am pretty pleased with the result. first is one done compared to one that I have not worked yet. Second pic is both done and showing some bling in the sun.
I got the engine out of the frame:
Then went to work on the frame. I cleaned up the area where I removed the passenger peg mount from the left side of the bike.
I removed the center stand and I am still working on cleaning that up. I also Removed the stock brake lever mount.
As for the other passenger peg mount, I am leaving it for the exhaust hanger, so I modified it. It does not need to be as strong to hold up the can, so I lightened it up some, and more lightening will be done later.
I also wound up really dirty, and Amy sent me straight to the shower!
