Hi all.....89 gs500e here...all stock.....rebuilding it for my g/f

What is the stock HP, Torque and Weight for this bike?

I am thinking of a stage 3 kit....w/pod filters...and a V&H pipe......

But I dont know if this makes alot of sense.....how many more HP/Torque will I be getting?

about 2 hp more than standard around 45hp give or take 5hp

h mmmmm...doenst seem that cost effective......

Your mileage may vary.

I believe the consensus (spelling sucks srry) is that the unfaired bike like the 89' are the hot rods. Local bike shop at my place test rode mine and when I said like 40hp he told me I got a ringer. Will post Dyno runs when I get around to it.

These bikes are nothing to sneeze at I assure you. Sure an R6 will beat them, but I won't be cramping 5 miles down the road. But I've beaten a Lancer EVO VIII so phhhbbbtt...

As far as power the word seems to be:
1. K&N or Pods
2. V&H
3. Re-jet carbs

As far as suspension (Far more common to mod than engine)
Either:
Heavier oil, depending on rider weight
Or:
Race-tech springs.

(Stock suspension blows.)

As far as mods I'd talk to AlphaFire, because he's like god of this stuff.

I can't say anything about that because I had to clean up what the previous owner left for me, so no chances to play yet. Some people say re-jetting even a stock bike helps.

As always your mileage may vary. Oh yeah, stage 3..... Too many grand turismo sessions for you. (J/K no hard feelings)

Oh yeah, it's her first bike right? Plenty fast enough, leave well enough alone.

"stage 3" implies Dynojet.  I believe that the overwhelming consensus around here is DON'T GET A DYNOJET KIT.  Apparently, the dynojet carb jets introduce extra variables into the mix and make it very difficult to get the bike running well.

I wont start a new tread for this question but here goes

I understand what a smaller front spocket and a larger rear sprocket do.  I understand the progressive fork springs do, ect. Point is I know why one does a lot of mods, but I dont understand what a rejet does.

I know this sounds stupid, but hlpplz

changes the air/fuel ratio. when you make i easy to get air in and out, you then need to add more fuel. which is what a rejet does,

on a EFI car ot bike you dont have to do this as it can do it itself

One would do this if one changed his or hers exhaust, or do it to give more fuel and give a kick
