Forgive me if I am posting in the wrong area, I am very new to this site.
So I'm looking into pod filters for my 79' CB400. I know that the second I put pod filters on I will need to re-jet the carbs. The carbs on this bike are off of an 82 CB450sc (yes... those are the ones that honda screwed up a bit). I'm suffering from that same mid range bogging issue as everyone else with these suckers so I decided that I'm just going to buy brand new carbs instead of fix these and re-jetting them for the pods.
Any suggestions on which carbs I should look for?
I have a budget of around $300 for the set. I have been thinking about the Mikuni TM32s (flat slide) or the VM32s (round slide). But hopefully you guys have some options/ suggestions for me.
Thanks!
32s are likely too "big". Maybe VM30s... Not too versed on this engine personally. That said, why not stock carbs rebuilt to work (as well as they can) with your intake setup? Probably way cheaper overall.
The problem with the stock carbs is that the ones on the bike have a manufacturing issue with them. It would cost me $50 just to fix that issue and get them running right. So that's my rational behind buying a new set of carbs, they should work better, will be cleaner, and much easier to use. I was doing more research and it seems like either 28s or 30s would be perfect, 32s are just a hair too big for a 400cc.
A quick look at the those carbs and they look very similar to the early 80's cb750/900 carbs. And the cb750C DOHC forum won't even discuss putting pods on them. The early 80's was a nightmare for the automotive industry trying keep pace with emissions regulations and those carbs are a product of that era.
As stated above be careful of the big is better trap. If most of your riding is full throttle big might work but a good idea is talk to the guys that sell them. Discuss the way you ride the bike and what you want from it. They will have a good idea of what you need on your bike. Good luck. I'm getting ride of mine on my 79 CB750 project.
The cb400 is 9.3:1 three valve per cylinder that puts out over 40 hp. I personally don't think TM32's would be too large, especially if you plan on upgrades down the road.
If I decide to go flat slide It seems I should opt for a 28 or 30. But if I decide on the round slide I believe either 30 or 32 will work. Can anyone confirm??
My friend has a set of minuki bs34ss carbs. Way too big right? Also I have heard that bs carbs hate pods on them.
Bs34ss is a cv carb. Totally different ballgame. Flat slide 32's would work fine but wtfdik. You seem to have the answers coming from somewhere else so why ask lol.
I'm just working off of multiple forums, and some guys who know a lot about this stuff, and using all this information into trying to find a definitive answer. My experience with bikes is minimal, I have spent my life working on cars so as similar as a lot of this is to cars, its just way too different for me to do without help.
If you had a 1979 cb400t and were going to run pods, what would be the carburetor of your choice? I'm stuck between the original carbs, a new set of round slides, or a new set of flat slides. And if you were to buy new ones, what size would you get?
Somebody else made my other suggestion which is use the stock carbs. Your answer was unrelated , saying that "the stock carbs" were from a different bike, lol. What he meant was find the STOCK carbs, as in the ones that came on the bike stock. Lol
But, the last thing you should worry about is putting pods on that bike.
Why do you want pods? If for performance, a waste.
Get whatever carbs you want. Your bike will run with so many different carbs its not even possible to list them all.
Well I found a set of 1979 cb400 carbs that I can pick up for a good price. I plan on using pod filters because of some frame modifications that wont allow me to fit the air box anymore. Im just here trying to figure out which carbs will accept the pods the best. Would I be better off getting these 1979 carbs and throwing pods on them, or would a new set of carbs accept the pod filters a little better?
