SUZUKI BANDIT 250 & 400 / Jap B400 VC carb jetting question
« Last post by Ivandit on July 01, 2019, 04:59:33 AM »
Hi there!

So last year I got a 6Sigma jet kit for my '94 VC, installed and running (apparently) well with a K&n air filter and stock exhaust.

The fitting instructions tell you to replace the stock jets with 105 on #2 and #3 and 102,5 on 1# and #4, which kinda made sense to me after reading about how that difference compensates the different cooling conditions on inner and outer cylinders, adding a bit of extra fuel to help #2 and #3 cooling:

But then...last week I was reading the japanese service manual prior to a valve clearance check and got a bit shocked when reading the carb specs:

So, apart from them being the same size (what's the point with the kit then??)...they are supposed to be fitted completely the other way around!! That is 105 on #1 and #4, 102,5 on #2 and #3.

Any thoughts/experience on this?

So far I've had different opinions, from "stick to the manual" (why the outer cylinders are set to be richer then??) to "the manual info is wrong" (hard to believe IMO...).

I just want to go back to stock jets, but I just don't know which is the right way...any help is much appreciated!! :beers:

and have been busy with a whole bunch of stuff. My wife has been working through health problems and I've kind of acted like her personal nurse, but.......that was part of the deal when I signed on back in 1972. For better or worse, etc etc. Fortunately she seems to be over the worst of everything at this point.
I see my buddy Bandit Allan has joined the board. We've spent many happy hours riding all over Alberta, BC, MT, WA and ID on our B12's.
I still have Big Red and she still remains my LD rapid transit camping bike and still runs and rides like a champ.
I finally had to replace the original chain and sprockets at 44, 870 km in August of 2015 so I can't complain that Big Red has cost a lot in repairs.......other than my crashes  :duh: and lotsa gas :grin: and those darn expensive Michelin Pilot Roads. :yikes:
Amazingly enough, another buddy of mine bought an '06 B12 and his is only 9 numbers earlier than mine. As well, a guy across the alley from another buddy just got an '06 B12 which he's street-fightering and his is only 100 numbers later than mine. Still more amazing, both those other bikes are what Suzuki calls "red" and both are non-ABS, exactly like mine. What are the odds ?? LOL  I wonder where all the other '06's are ??? :motorsmile:
Well, that's enough from me for now.
Keep the faith, Bandit riders.

GENERAL MECHANICAL & TECHNICAL / Right footpeg/brake pedal parts stack-up
« Last post by JerseyDog on April 11, 2019, 08:32:47 AM »
Good morning...
Have to replace the right-side footpeg/brake lever bracket on my 2000 GSF1200S. Can't seem to make it work right - if I tighten the bolt that goes through the bracket/brake pedal into the footpeg too much the pedal won't operate properly. Too loose and the bolt wants to back itself out. The parts diagrams I've found on-line are of no help, they don't provide enough detail. Does anyone know where to find a decent service manual, or perhaps provide a copy of the page in question if you have one?
