Hi all, I just paid 50$ for this ol 83 model CR480, and I'm all pumped up and feel like a kid again! I tore down the top end, cause the cyl ID was .020 past the service limit, and while I'm waiting on the cylinder to be punched out 1mm over, I'd like to order a flat slide Mikuni. I got a pumper TM33 on my DR350, and I love it, but the problem I'm having is on the TM38 Mikuni, the spigot sizes available are 43 and 47, but the factory Kiehn carb measures 2-7/16, or roughly 62mm. So If I order a TM38, what do I do about the air inlet hose coming off the air box? I also read the jetting for the TM38 on a 480 is: 320 Main 40 Pilot Q8 Needle Jet 6FJ40 Needle 4.0 Slide Not too sure what setting to put the clip on the needle... Any help would be greatly appreciated. I'm gonna have it running next weekend, but I'd really like to have it breathing through a new Mikuni vs a 30 year old Kiehn Thanks again!
