Received the OEM 2000 parts-fiche from my dealer last weekend and here is the list of differences that can be found just by looking at this fiche with the parts for both the 1999 and 2000 model on it long, hard and (dare I say) intelligently enough, although sometimes – of course – you can only see that the partnumbers are different and there’s no way to find out what has changed, except for some educated guessing or remembering things put forth on these boards by others before me regarding model-year 2000 changes.
I have left out some small things that I thought would definitely not be interesting for anybody.
The crankcases (sold as a set) have already been changed during the 1999 model-year from certain framenumber onwards and now for 2000 the part-number has changed again.
As far as engine-covers go, some of these have different part-numbers for 2000 and also a lot of the related bolts and gaskets have changed. Changes include: clutch-cover and –bolts (M6 now, weren’t these smaller?), starter clutch cover gasket and bolts, starter idle gear cap bolts, generator cover bolts, engine sprocket cover and bolts, crankcase breather cover gasket and bolts.
The airbox parts as a set have a different number but the only singular item different is the breather tube for the crankcase breathing that connects to it.
Fuel return hose and its clips are different.
Fuel hose is different and there’s no longer a clamp securing it somewhere halfway.
(some of the above combined makes sense relating to JC’s remarks a while ago about the crankcase breathing now being done with hose directly from crankcase breather cover to airbox and MAYBE all this was done just to prevent the fuel line kinking problem by getting that stupid plastic oil return tank out of the way completely and using different and differently-routed fuel lines ???)
Piston-rings are different number for 2000.
Cam chain tensioner is still the same number as replacement used in official recall (so who was it talking about 3rd generation, this is still “only†the 2nd version).
Clutch springs, clutch spring bolts and clutch spring support bolts are all different.
The combined 3rd & 4th drive gear on the countershaft has changed.
Shift cam stopper has changed and so has the gear shift link arm (the small part that you slide onto the shift shaft). Does this mean they acknowledge a shifting problem?
Not completely clear if the ECM/EFI control unit was changed but don’t think so.
Speedometer and tach assembly has a different number.
One of the adjustable mounts for mounting engine to frame has changed.
Part-number for fuel tank assembly is different, but it seems a lot like the only change is related to the use of a different fuel level sensor that has a different way of mounting to the tank.
Handlebars and its clamp-bolts are different.
All (front and rear) brake disc bolts have changed as well as the bolts mounting and keeping together the front brake calipers. Both front and rear brake hoses and the clutch hose have changed too.
The OEM rear tire has a different part number.
So, there you have it, guess I've put you all to sleep by now, hey?
It's a nice combination of changes for different reasons that I can see here, based on my own experiences with my Busa and on "problems" vented on this board, leading to other parts in the end.
