No, i still give mine a good run out 5-6 times a year. I personally think your better off sticking with the origonal carbs, a few people have tried unsucsesfully with rs carbs, and i dont think the gains, ( if any ) are worth the hassle, your probably better off trying to scource an HRC jet kit or some f3 carbs. I think fontty of this forum had some on his a while back, he'll probably be along to tell you the gains or pitfalls, good luck with it though.
