    Hi everyone! I'm new to this forum and so far I've been impressed by the wealth of information here. I recently purchased a 1974 CB360 in pretty good condition. When I start it up, I'm getting some backfire and it wont stay idling. The previous owner had mikuani carbs installed and...

    So I originally posted on the start of this build a few months back and it's damn near completion. Before I started the build I wanted to make sure the bike would run so I did a carb clean, short circuited the coils, gas in the tank and after some bowl adjustments It started up but it was...

    Hi everyone! So I'm just going to jump right in. I've recently bought a 1970 Honda SL350 K0 that has a 74 Honda CB350 Twin motor. The bike idles great at around 1,100 just sitting in the drive way and on a quick trip around the block. But when you ride it for a longer period of time it starts...

    Hello everyone, first time poster here. I have been unsuccessful at getting my CB360 to idle. The bike runs well if I hold the throttle open. I can even get it to sit low in the rev range (~1400 rpm) if I just barely hold the throttle open, but as soon as I let go, the revs drop and it dies...
  5. Fuel Supply and Carburation
    I did some searching around this thread and was unable to find anything, so sorry if there's already a thread with this answer Anyway, the problem is that I cannot get the idle to go below 1500 rpm. I had just recently rebuilt the carbs, with 150 main and 36 (i think) pilots, and had synced...

    what's up. so i have a 1971 CB175 that I bought a while ago and got running. (i'll list what i did below). but now it's either (1) idling way too high (4-5k) and fuel adjustment screw doesn't respond, or (2) idling too low and shutting off (will stay running if throttle used), or (3) most...
  7. Fuel Supply and Carburation
    Hey all! Long time lurker, but looking for your expertise! Hopefully in the right subthread, I've never been able to figure out why the right side carb of the VM30s are making this coughing at idle to low rpms almost at stop. From cold start to a 40 mile ride it'll be fine. I can run it up...
  8. Fuel Supply and Carburation
    Hi there, I'm looking for help with my 1974 cb125s. After a lot of fiddling with the air and idle screws the bike starts first kick, and idles well (maybe slightly faster than i'd like? but pretty healthy) but as soon as you give it any revs it dies. Can anyone point me in the right direction...
  9. Fuel Supply and Carburation
    throttle is at the idle position i rebuilt the carbs and they appear to be synced the engine floods sometime i fixed that but the engine goes straight to redline after starting and stays there i tried to adjust both the idle and other screws i believe its the air mixture screw i messed with both...

    I have a 1971 CB175K5. Quick history, pistons were frozen. After 6 months plus months of effort finally got them out. Had the engine bored out to 0.50. Put the engine back together and on the bike. Cleaned the carbs making sure all passages were clean and set the float bowls. Engine started...
  12. Fuel Supply and Carburation
    Hello Ladies and Gents. I haven't been around the forum for some time since selling "Herbie" the 1980 CM200 a while back to a friend. I've since had an SL350 land on my lap and I'm working on getting it running and could really use some help. Here's the scoop. I drained the gas tank and...
  13. Engine Discussion
    Hi All, This is my first time posting although I have found a lot of helpful info on the forum. A few months ago I purchased a 1974 CB360. The only issue I found with it was that it had a hard time getting above 5000 rpm and later I found that it wont idle with the choke fully off. So far I...

    Hey guys, My '73 CB450 runs great when cold. Idles and accelerates fine. Tho, after about 20-30 minutes once the bike is really warmed up it wants to die at every stop light. I have to keep on the gas ever so slightly to keep it alive before the light turns green. By the time I pull in my...
  15. Fuel Supply and Carburation
    Still trying to get my '73 CB450 running. After fixing an air leak caused by a stripped intake manifold bolt and getting the ignition timing and valve clearances set property Im still having issues while idling. The most current symptoms are: - revs high upon starting - stays high after...

    To start, the left side is perfect at all ranges. I can also throw the left carb on the right side along with the right fuel line and it runs perfect. I've also swapped jets and the diaphragm from the left, working, carb into the right and still had erratic idle and acceleration with backfiring...

    Hello, looks like a nice forum and community here. I come from the land of Ninja 250's, where all of my mates went up to their 600 Super sports, I took the route of an even slower bike haha, my new bike is a 1993 CB250 nighthawk that is pretty much cafe'd out. Love it so far, had it about a...

    I have searched this topic on the forum and haven't found the cure, yet. So I am starting a new thread in hopes that one of you gurus can set me straight. I am working on a 1971 CL450, with approx. 13k miles, that has a very high idle. It will sometimes start and idle at a reasonable level, but...
