Hi
I have a zxr750 with a 900 engine build in.
I had it tested and it only makes about 115 hp on the wheel.
does anyone have some ideas what I can check.

it still has the 750 carburetor on it. can it be that? can I solve the problem by getting the 900 engine carburetor??
or can the problem be somewhere else?

I had the co2 testet and checked and adjusted the fuel/air.

hope you can help.

Best regards Esben, denmark

Which kind of ZXR do you own? J or L or whatever?

Hi EsbanBoll,

its a 1994 model.. thats an L model as far as I remember.
I dont think the carbs are restricted..
i just got the and with the 900cc engine in.
så I dont know enything about the 750 engine.

maybe your chain is very old?
there should be about 135 - 140 hp at the clutch... with about 25 % lost to the wheel...

25% Verlust von was? Von 135 PS an der Kupplung und dann zum Hinterrad?

Je nach Zustand eines Motors und der Kette, gehen zwischen Kurbelwelle und Hinterrad 8-12 PS verloren.

haben diverse diagramme so belegt. aber wenn ich mir so manche ketten und radlager ansehe, wundert mich das nicht.
