I finished welding the bungs onto the old Beast muffler, so I painted it and installed the original scooter heat shield. It looks ok.
I rode it over to Jim's house tonight, and I was able to cruise above 70 km/h! I actually passed three cars in a 60 zone.
All of this is still with the stock #80 main jet, so I'm hoping for good things with the new 88 that's on the way. Curse the Canada Post delay. :(
Jim took it for a quick rip, and he couldn't stop grinning. He loves the exhaust note of the new Beast muffler, and he couldn't believe that he is now able to bury the speedometer (it only goes to 70).
I'll report any changes after installing the new jet, if it ever arrives.
Here's the new heat shield on the Beast muffler:
