Might be a little small, but I cannot remember the bore/choke size, R1 carbs are the best as far as I know.

Have they been set up properly? When I put my 1.9 on R1 carbs years ago it was well down on power and really lean, fitted larger main jets and it went like stink.

dont know if they are set up right? its quick up to about 60 and just wont pull after 80? dont want to spend money at a rolling road to find out that i the carbs are too small anyway? another question.. if i buy some 1000 carbs i wont have to change the fue pump that is on the car now wil i? cheers

Unlikely, it should have the fuel pressure setup about right already.

 

Before you change them you should check the fueling is OK to determine whether they are too small or just not setup, otherwise you could end up with the same problems later.
