You have to pull the airbox apart to gain access to the throttle bodies and the brackets where the cables attatch.
The 998 throttle is basically the same as the 916/996 throttle.The only differance is the older bikes used a 'cold start' button underneath to crack open the butterflies while the 998 uses a lever the same as 749/999.

Forgot to mention,my wifes Y2k M900i.e uses the same throttle as the 998.The injection throttle bodies and mechanism is very similar to the ones fitted to the superbikes,.....cant see why the cable would'nt fit either.

you could do this . . .

I think they are about £100 now and I fitted mine in about an hour - it can be done without taking the airbox off - and it uses two cables!!!

3 cam options - sweet!

If you look at a 998---916 throttle cable it actuates the butterflys from the right side of the H cylinder.

The 999 range operate the throttle butterflys from the nearside of the V cylinder.

Other than turning the bellmouths around, you need a longer cable!
