I am trying to get more power out of my 97 Savage. Does anyone know what Jet I am to use for increaseing my power and maybe tork. I also heard that I need to remove the white spacer that is located inside the carb. Some people remove and others say to shave it in half. What seems to work better???

I am in Austin. I have replace my pipe with a Harley Sportser Pipe. It sounds so much better now. I sounded like a Singer Sewing machine before. Thanks for the info. I will give it a shot.

10/4.Thanks.

You will need a better exhaust & jetting to get decent powwer out of this little bike. The 1/2 spacer seems to be the most recommended approach.

So I have the Harley sportster pipe, Shaving my spacer in half and rejeting with a 152.5 main. How about the pilot jet?

Nothing etched in stone with the HD pipe and the jet size.  You might not need that large.  Buy all 3 sizes above the stock 145 and be prepared to swap them until you're happy with it.  Backfires aren't cool and neither is black soot.

If you change the bowl screws to allen head the first time, it is easy to swap the main jet later without removing the carb.

Oh yeah, good point.  Forgot that was done too.  Try to get stainless if you can.  ACE hardware carries 'em in my area.

Backfires are generally caused by a lean mixture (small jet).  Soot or blackish smoke would mean a rich mixture (large jet).  The "sweet spot" is in the middle where it burns clean, sounds good, and has good power.

The other day, based on a guys exhaust color, very few backfires, and other stuff I opted to just change his main jet 1 size to a 147.5.  We could have gone bigger, and may anyway, but black smoke is nothing more than wasted gas.  So, we'll see (see note)...

If you have a stock exhaust you can simply go up one 1 size and change the spacer for a lot more fun and less noise.  Then if you change other stuff for better flow, you can increase the jets even more just to keep that sweet spot.


Note: this was an unusual case too.  The Stinger has a 2002, with only a small amount of bluing on his SuperTrapp (w/ 8 disks) and no bluing on his header.  I didn't hear it running before this work but he swears it never backfires.  Even better, all his jets were stock.

So, I thought it might be better to just try to just get more power without disturbing a good thing.  1/2 spacer and 147.5 is all we did.  We cranked it before I left, but it wasn't ready for the street yet.  Time will tell.
