Title: General Questions
Post by: charleym3 on July 22, 2004, 01:38:45 PM
I hear a lot of talk about rejetting the carbs.  Can someone explain why I should do that?  And, I'm fairly mechanical.  Can I do it?  I have rebuilt carbs before.  It was from a 76 isuzu Pick up truck.

I don't have a garage.  What kind of cover should I get?

My GS wants to see around 4K on the tach to get away from a stop light cleanly and bogs down more than a bit.  Is that normal?

Where should I go for a replacement rubber thingie for the shift lever.  (The last owner seems to have ridden with one foot on it always.)

I know there was more but that's all I can think of at the moment.

i've never looked that into it, but the gs is stock setup to run just a bit lean (not harmfully lean, but lean nonetheless) if you want to "awaken" the motor by giving it more air, you can do that, but since it's already lean, you need to rejet the bike. rejetting it puts bigger pilots and mains in the carbs, allowing more fuel to enter and properly mix, keeping the air/fuel ratio correct. if i'm not mistaken, after a rejet you usually run a bit richer than factory settings.

summary: if you're trying to add airflow (new air filter/exhaust) jetting is needed to enrichen new mixture.

i thought "lean" meant too much air (too little gas), and then you rejet to get more fuel in.  and you almost have to rejet when changing filters, because an aftermarker air filter gets even MORE air in, making it even more "lean"

of course, i could be wrong  :dunno:
