I thought "project big One" was the CB1000SF - I seem to remember reading that Honda built the 1000CC version after the success of the CB400SF and called it "Project Big One" - "One" as in "One Litre" and also as in "Bigger One(400SF)". May be wrong, it does happen :D

There is a project big one CB1000SF, have only ever seen one though quite regularly at the Bury Hill meet. Looks just like the 400 only bigger!

arghh ye i meant 1000 ... my point was i was trying to clarify it so alex understood u didnt mean the 400 went that fast m8.

And less fun to ride

in 1992 Honda made two identical looking bikes, a 1000cc and a 400cc bike

The Honda CB1000 Big One (as in one liter) and the Honda CB400SF Project Big-1 (as in the same project as the one liter bike).

The CB1000 was succeded by the CB1300 in 97

If your bike isn't hitting its top speed do what alexi suggested, first check the air filter, it can be as easy as blowing it off, then check the plugs for excess carbon (hopefully not oil), then carbs and last valves. I prefer to start with the cheapest method first. I've never used any fuel additives yet myself, but will be trying it.

then carbs and last valves

Do the carbs last, as you're then adjusting the fuelling to suit all the other settings. If you set the fuelling and then adjust anything else (valve clearances included) you'll need to re-set the carbs.

And don't forget to check the spark plug gap! If they've done more than 10,000 miles, replace them.

oh and the cb1000 big one does exist, theres one on bike trader atm!

For those who aren't aware:

The Japanese have long tested all kinds of designs on their home market first, before selecting the most successful and developing them to appeal to other markets. This is the case with motorcycles, however strict Japanese licencing laws make passing the test to get a larger capacity machine than 400cc difficult. Whilst the fashion in the late 80s in Japan was for race reps, and hence 400 and 250cc versions of CBRs, GSXRs, ZXR, FZR etc; in the 90s the fashion changed and this developed into home market demand for tektros - bikes that had the retro look of 70s musclebikes, with the technology of the moment, i.e. decent brakes, reliable electrics, modern suspension and chassis.

The CB400 Super Four is a tektro, and was launched to test the market for the introduction of the CB1000 'Big One'. Competitors included the Bandit (including lovely Ltd versions with the Bol D'Or fairing, and later variable valve timing version) ZRX, XJR. There's also some rare stuff that hardly reached our shores such as the Zeal and Zantius. Although the CB1000 went out of production, Honda continued updating the CB400 SuperFour as it was always a popular home (and other asian) market model, and as such is currently in production as the V-Tech Spec III. The CB1300 came in as we finally tired of sportsbikes, to compete with the likes of the GSX1300, but is certainly more closely related to the current 400 model than the former CB1000.

Those of us old enough still to have copies of GreyBike knocking about (now defunct) have plenty of this history in those old pages.

I Know the CB1000 "Project Big One" exists, but was there ever a 400SF that had "Project Big One" written on the side panel? I thought the CB1000SF got the name because it was big and one litre. The 400 is neither.

What you reckon TekroG

Of course there is. My CB400 has Project Big One written on the side panels. As I said, introduced as a 400cc version of the CB1000 for the home market, hence same styling down to the stickers. The Japanese tend to think anything written in English is cool. No matter whether it makes sense or actually refers to the 1L capacity of the larger machine.
