The GS can use richer jetting than what comes factory stock, even with the stock pipe. They are jetted very lean from the factory to pass emission laws. So, re jetting for this slip on would benefit the bike, producing more power and a smoother powerband. It will also warm up much quicker.
@@twowheelseatingmeals-motoj8080 If you want it to run correctly. And remember, you want to richen the fuel mixture up, but not overkill. Lean makes power and smooth running, but too lean will cause detonation and engine damage. Too rich will just cause the bike to run like crap, period. I have a Yoshimura exhaust and a K&N lunchbox filter w/ airbox removed. Factory jetting was 122.5 mains, and 37.5 pilots, if I remember correctly. I think I took the tank and carburetors off about 25 times, but ended up with 140 mains, and 40 pilots, with the air/fuel screws around 3 and a half turns out. It runs perfectly, with no hiccups, and smooth acceleration with no burps or coughs, LOL !!!! I have aftermarket needles in the carbs, with the clips on their lowest setting, but you should be fine with good stock needles, left right where they are. They don't have removable e-clips, but some people use washers to raise the needles and richen the mixture. I can tell you by experience, this is totally unnecessary, and will simply cause your bike to run like shit. Leave them alone. Tweak the mixture with the jets and air/fuel screws, ans when you get it right, you will be a happy camper. I started with the 40 pilots and 150 mains, and worked my way down on the mains until I got clean acceleration all the way across the rev range, and then fine tuned with the air/fuel screws, which must first have their factory installed plugs removed by carefully drilling, so that you can adjust them. Remember, each 180 degree turn of the screw/screwdriver is HALF a turn of the screw. Count each half turn as you screw them all the way in, so you will know where they were set from the factory, and then back them out 3 FULL turns. That should get you in the ballpark. All this may vary, according to your location and altitude above or below sea level. Good luck !!!!!!!!!!
It made a deeper sound upon acceleration/take off. Once again the video doesn't give the most accurate audio. When I sold this bike the buyer said he was surprised at such a small displacement bike making such great sound. The video recorded by my phone picked up more of the higher notes coming off the engine, rather than the tailpipe.
Hard to tell the difference on RUclips. I also changed the muffler on my GS500F with an aftermarket and yes it changed the sound some....Not enough to justify the cost of the swap.
With this exhaust there was no need to rejet. But that isn't always the case. On my triumph I needed to adjust the efi after a slip on install. I used my cell phone to record this. It sounded better in person. Great around town bike.

Thinking of purchasing a Yoshimura R77 Stainless steel carbon fiber tip.
Any new exhaust would need re jetting for the GS500F, right?

Thanks for the video. Nice looking exhaust! Good job.
I purchased it off a local motorcycle store in Houston.
the stock makes me cry on mine.
is it broken ?
Its a 500 ppl get a atv race slip on like a Dasa or white brothers it will be lighter and sound better
beefed up quite a bit.
Sounds terrible and not what I expected.
I think, thats no difference!
I can hear it
Can somebody tell me full name of this yoshi exhaust?
***** I'd like to know too Jason caballero Jason Caballero Jason Caballero
