Afternoon everyone, I would like to ask for some help, if I may. It’s a cold 25’ here today so naturally I thought I’d head back out to the barn and do some work on the bike. I’ve been having some trouble with it backfiring through the mufflers at idle, once it’s warmed up and the choke is backed off. It does go away at about 2,500 – 3,000 RPM. This problem wasn’t there before I removed the engine and replaced the clutch. I have checked the air cut off valve and it appears to be working; I made sure that the new o-rings for the carbs were in place, double checked the plugs and wires at the coils. I did find a cracked vacuum line from dry rot, so now I’m planning on replacing all the lines under the carbs. My question is does anyone know what the ID sizes are for these lines? My eyes aren’t focusing to well today (another sign of the times) but I can tell there are 2 different sizes. I also would be very grateful for any ideas or suggestions that would help fix this backfire problem. Thankyou.
