Hello, I’m driving a GSX600F BJ`95 so GN72B throttled to 34hp.That’s it’s not bad until today, so until 120 she gets quite well, but after that she tortures herself upwards. yes I know she’s throttled, but when I drove the gsx600f from na friend today I also throttled to 34hp I’m a little scared how much better her runs. the machine runs without another 180 on the just, as if she had throttled to 50p. now my question, it would bring what e carburettor times to have synchronized and to have the valves adjusted. she has now 44000km down the from my well-known 23,000km. bought it with 33tkm and then throttled, does not know if the previous owner did this at all, so it would be due. would you notice clearly, you certainly have more experience with it. oh so and has someone guessed what would cost about that? valve I would maybe still do it myself, but gassing lacks me anyway a syncrometer and there I would probably do more harm than it would help. and having synchronized can actually never hurt, certainly not after throttling and installing a K&N exchange filter. Thank you for your reply
