  1. Fuel Supply and Carburation
    So I bought a 1982 CB450SC that ran like absolute garbage. One plug fouled out and the other insanely lean after a ride around the block. A little bit of inspection found gummed-up vacuum pistons and a plugged idle jet on the left carb. I tore everything apart and cleaned off the molasses and...
  2. Engine Discussion
    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...
  3. Fuel Supply and Carburation
    As part of a very long process in nailing down what was wrong with the way my 450 idled I threw a bunch of money at a set of Mikuni VM32 carbs. Bought one of them kits from Power Barn which claims to be set up for the 450 and winced mightily at not only the sticker price, but the import duty I...
  4. Wanted Parts and Bikes
    Hello Listers, I am looking for a pair of 160 size carb jets to fit my 1968 CL175KO. Many thanks. Michael Mpls
  5. Fuel Supply and Carburation
    Seems like i may never. Thought id have some fun building a custom in my spare time. Pick up on that runs, mod it, tweak it... have a little fun like when I was a kid. But, it's turned into a he'll storm with my limited time to work on it. I've posted some carb issues previously and since...
  6. Fuel Supply and Carburation
    Ive read the main sticky on rebuilding rejetting for pods, 125 and 90s.... and followed it to the T; less the 127.5 jet for straight pipes. I jetted with 90s and 125s and running pods off the back of carbs, no stacks, and headers only. So I really didn't follow the main sticky to the T. I get...
  7. Fuel Supply and Carburation
    Hey guys, My superdream is having problems and seems to be running rich. Always has sooty black plugs and i'm wondering if the jet sizes are wrong, but I can't seem to find any information on what stock jet sizes are. I've looked in the OWM and online but no luck. Thanks for helping Cheers Isaac
  8. Miscellaneous Discussion
    Hi everyone-- New member here with a 1974 CB200. Has only 4,700 miles, and purs like a kitten(when it's running). Sometimes when I would ride, once I would come to a stop the bike would shut off. Note: I've been only been able to ride with the choke on, so I think I just need to adjust my carb...
  9. Fuel Supply and Carburation
    Almost done with my 350 but had to rebuild the carbs. I figured I'd ask, now that I have the things apart.... I have Keihin 3D carburetor models, but am using velocity stacks and shorty mufflers... What jets should i install in my carburetors that will work best with this setup???????? I...
  10. Fuel Supply and Carburation
    Hello All, I have put pod filters and high-flow mufflers on my CB360T, and immediately noticed a lack in power when going full throttle (which I of course expected). So I got my hands on a jet kit from 6sigmajetkit.com and have put the following into my carbs: - 78 Primary jets (changed from...
  11. Fuel Supply and Carburation
    Can anyone point of the most straightforward and non-destructive way of removing the jets? I assume mine are stuck with 46 years of gunk in them, but I still can't see which side I should be pushing them out from now that I now that you shouldn't be using a screw driver even if it looks like...
  12. Fuel Supply and Carburation
    Hello everyone. Im sorry if this question has been answered already but I have been searching for a while and have not found a definite answer. I have a 1971 Cb175. I am installing straight pipes soon and would like to know what size jets i will have to run and what else i will have to do to...
  13. Fuel Supply and Carburation
    When I purchased my 86 CB450SC it came with Keihin VB31A carbs on it (no clue why, didn't have the knowledge then, and huge lack of info on these available). I've had popping on decel (clean carbs, no leaks or major ones, decent sync). I was going to remove my airbox + hbox + add pods + new...
  14. Engine Discussion
    Hey all, it's been awhile. I've got a CB160 that refuses to idle and could use some fresh ideas. I've done some searching which has helped with troubleshooting thus far. Here's the typical behavior-Bike starts on first kick, revs up like crazy (as a result of idle speed screws being turned in)...
  15. Fuel Supply and Carburation
    I have been working on a 1971 CL175 scrambler with off idle hesitation. Purchased this bike for the wife's first bike but the hesitation is stalling the motor on her. The carbs were rebuilt by the previous owner and I'm convinced the wrong jet, needle and slow jet were used, the wrong kit. The...
  16. Fuel Supply and Carburation
    Hey guys, im fairly new to motorcycles and brand new to the great resource that is hondatwins. So I have been looking at late 60's early 70's honda twins and 4's and finally settled on a bike the other day. It's a '73 CL350 in pretty good fully running condition. My only concern is that it is...
