Oh... I also went plus 1 on the counter shaft sprocket (17T) along with the jetting change.

EDIT: Unneeded Rpm/high shift points are the biggest killer of Mpg, even on a bike that's at a 100% state of tune, yes I know...the Fun Stuff   :cry:

I usually just ride mine to work and back so it rarly sees high rpms . But when i take her for a blast with a few mates shes worked pritty hard almost all hard acceleration is done at wide open  throttle mainly because they still have there supersports bikes and i have to ring the neck of the gs just to keep pace.

Still tempted to try a 150 main now ive got my idle and mids all good , just feel it has more to give . . .

Heheh don't forget crasm, someone said on here that GS stands for go slow ;)

My jets seem to have been lost by royal mail, spoke to motocarb and they've sent me replacement ones, great!

Suzuki's naming definition for the GS/GSX series is:

GS = Gran-Sport
X = 4 valves per cyl
-
R = race tuned
displacement in cc
Additional letter for specific features; e.g. F = fully faired, G = shaft drive, etc.

So a GSX-R1000 is a race tuned 1000cc GS with 4 valves per cyl.

Turns out there was a mistake in the system, some guy rang motocarb and told them he had received two packets of the same jets lol! His name was one letter from mine. Ah well! Ordered 22.5 pilots too! And bought an air compressor for some spray painting, sweet!

Think i might try 22.5 pilots and 150 mains at some point in the near future i dnt wana play with it but somethings just need to be tryed!!
Wont be until end of april now as its mot is in 3 weeks :sad:

Jayke

Yeah that's what I'm gonna do too, 22.5/65/150 I think. But I need to do the needle first then test the top end again, been waiting on these jets for over a week now lol!

This is why technology can't be trusted all the time, silly little errors! Just damn glad that the guy that was getting my jets actually gave motocarb a ring :)

Good luck with your mot, sure she will be fine ;)

I just did my first ever rejet and the first ive taken apart the Carburetor. It wasnt as bad as i thought but there seems like a lot of hoses that i had to disconnect. I have a 2007, am installing a lunchbox filter as soon as it comes in and have a yoshimura slip on exhaust. i just put in 20/62.5/142.5 jets in it. im hoping that will do but need the weather to cooperate before i test it out. From what ive read, it sounds like i might need a 65 mid though. im still learning about how it all works but i think i understand most of it. i did start it up briefly though and it was idling at 4k rpms. i havent adjusted the idle screw or the mixture screws at all yet. im waiting for the lunchbox to come in

Was this without a filter?  that would result in a lot less restriction on air flow and affect how it behaves.


On a side note: I now change jets without even removing the fuel tank; it's a bit of a pain but not as much of a mess to deal with in terms of fuel spillage.

Yes radodrill, that was without any filter on it. Also, where do I adjust the mixture? The spot where I thought was the mixture screw is just a brass looking cap.

On the US and California versions of the bike, there are brass plugs (size of a pencil) with a small hole covering the mixture screws; you'll have to drill out the hole a bit then thread in a screw and use it to pull out the plug.

Yeah blue its quite scary at first but now I've done it a few times and it's actually quite fun to do. :D

My mid mains got sent back to the royal mail depot because the postman is an ass and doesn't even knock on anymore so I gotta fetch them and my pilots should be here in a few hours hopefully! So gonna do them and the needles today if the pilots come! Gonna be fun. :P

So I've changed the mid mains to 65s and the pilots to 22.5s and adjusted the needles too, first thing I've noticed after riding it is that the pre 3.5k revs is absolutely horrible now. Splutters like hell until I reach 4k then it's fine.

I think I might have been right in my thinking that my pilot was too rich. It's muuuuuch worse than when I had my 20 pilots in. Any advice? Currently at 3.5 turns too. Gonna try 4 just incase

How so?


Have you tried 22.5 pilot with 62.5 mid-main?

It just splutters like the problem I had before. Hesitates like hell before 3.5k then is fine after 4k. The revs rise really well after 4k though and the acceleration feels better. 50-70 was a breeze which not so much before.

It's mainly when Ive been riding then stop at traffic lights. Tends to do it then. Does that mean I need to go more turns on the screw or less? Counterclockwise = more turns and clockwise = less right?
