OK,

Is it possible to change camshafts between these models?

I have bought a set of slotted SP cams from a M model but until I open the cover on the motor wont know if there are any differences in them.

Next, i have bought F3 racing cams (Genuine Kawasaki racing) these are "Unfookenobtanium" as they are not available from the factory any more

The seller has stated they will not fit '89 '90 models which if that's the case they will be up for sale - but only if and when I establish they really wont fit, christ i might even buy a L engine to put them in, do they fit the H frame?

Part No for the cam's are:

'89 J1 IN 49118-1071
EX 49118-1072
Finished

'90 J2 IN 49118-1080
EX 49118-1072
Finished

'91 M1-6 IN 49118-1089
EX 49118-1090
Factory Stock

F3 Racer IN 49118-1098
EX 49118-1099
Finished

Panic over, wife done the translation.

Need to swop cam sprockets to make them work in a '89 '90 or ZX-4

i dont see why they should be different, the heads are the same, as are the cranks

i've certainly put L cams in an H and vice versa, and have been told by a couple of tuners that they all swap, even to look out for ZX-4 cams to fit to a zxr-L




L engines fit H frames with the temp sender houseing spun 180 degrees..

Cams described in the 1989 F3 race kit manual,

IN 49118-1074
EX 49118-1075

its a good read that ..

at least, it gives a clear idea of the differences between stock/sp/kit stuff even if modern tuners would go a bit further than the manual takes you..

wish i could get hold of one for a later model..
