Got my new windshield installed after sitting in my bedroom for 4 months. It's so nice to be able to see where I'm going. Old one was pitted and hazy between the layers of glass. Couldn't see shit when light hit it straight on. Cost $50 and took the guy half an hour to install. I did the prep work beforehand.
Old glass out
New glass in
Since I don't have a heater for the defroster vents to be functional, nor do I have a speaker in the stock location, I used some scrap pieces of exercise mat I had left over from another project, to block off the uglies beneath the mesh. Looks much cleaner.
I laugh at those Weber heat shields. The big flaw is that they screw onto the carburetor using the screws for the accelerator pump chamber... durr what do you think causes fuel percolation? Heat soak! Carburetors being over the exhaust doesn't help. You need to have an air gap for a heat shield to be effective. Exhaust wrap is more to keep heat in, not block it. People have used that gold foil stuff to block heat.
It's very difficult to drive when the fuel is percolating in the accelerator pump chamber and float bowls, not to mention embarrassing. Someone may think they're running too lean if the car is bucking and not responding to throttle, but it's possible the problem is heat soak. I had issues with that, and a heat shield solved it. Lack of air flow can also be an issue.
Going off topic again, sorry, but it's something worth mentioning. Could save someone reading this in the future a lot of grief.
Seriously though, a heat shield and some soft mounts (between the carb and manifold) will help, not just for HP, but for around town driving too.
Yes, very important, I made my own heat shield, $30
x3. Makes all the difference in the world, especially with the short Mikuni manifold I have which puts the carbs right over the exhaust. I made one with stuff I had laying around. Just sheet metal and aluminum band for rigidity. No extra heat barrier stuff necessary. I can touch the bottom of the carbs and they are barely warm. The mechanical fan also helps push hot air away too.

Aluminum flywheel in a 510 is fine. I have an 11lb Tilton 225mm flywheel. With the clutch the assembly weighs about 30lbs. Perfectly fine on the street. It's no more difficult to drive than my old motor with a stock flywheel. Just revs faster.
