Flat side carbs?

[pete376403]

The modern c.v. or butteryfly valve carb has been around for about 25 years to be more precise, which makes them newer if taken over the period that carbs have been around for (about 112 years) and not newist, because they have since been replaced with FI systems. Before the modern c.v. carb the skinners union c.v. carb was the most common type as it had a variable choke. This style I mean as being the older type.

Oh pigs arse! Haven't you ever seen a Stromberg? They were on Hillman Hunters from the late '60s. Avengers also had them.

Havnt you seen a carb on a plane before - they are a totally different design from the standard motorcycle design and have nothing at all to do with motorcycles.

Planes, trains or automobiles - a carb is still a pipe and a pinhole - after that it's just details

ok then......

ive got flats on my ZXR, 39mm mikuni's. there pretty cool on the track but they are a bit naff on the road. very snatchy and hard to get off the line quick (unless your experianced with the setup as you really need to ride the clutch hard like a 250 4 cyl).
its quite funny to watch people who never have ridden a bike with them before, a good mate of mine took off on my Zed for the first time and stalled it at about 20kmh just because he tried to give it nuts too early.

i cant comment on all types but on my bike thier awesome from the midrange onwards. bottom end... no good.

For the CBR250? it is techincally possible - try a set of Kiehen FCR carbies (if you can get a set slmall enough). Expect say aroudn $2k for the carbs, plus jets, plus trumpets, plus...
The do the business on FZR400s - we had 7-8hp on a FZR with FCRs. A megacycle cam was around another 5hp.
Of course, they are pain on the street, and need jetting for weather changes...
