I have read some of the past posts on using the drop in K&N air filter (SU-5589) with the stock airbox.  What jetting for a 1996 bike is recommended (stock exhaust)?

Please let me know what jetting you used with or without the restrictor fitted.

Thanks in advance

Ok I am stuck on whether to go for 125 or 127.5 mains using the drop in K&N for the stock airbox and stock exhaust.  The jets cost a bit here in Australia so I don't want to buy too many sets if possible.

I guess from the posts on this topic with the restrictor in place I can leave the carbs at stock (one carb with 125 and the other with 122.5 main jets - apparently this was standard issue for a few models).  If I take the restrictor out - stick with 125 or go up to 127.5 - anybody tried this?

Thanks
Conrad

Restrictor in... should be able to run the stock jets... Oh BTW that 122.5 and 125... that just is wrong. One cylinder doesn't run different than the other... its not a V twin...
Aussie bikes have 40 pilots and adjustable needles, so you could actually lift the neelde 1 clip if it starts feeeling lean.
Cool.

I ran the k&n filter w/o restrictor w/ the stock 122.5 for a few months...took out the restrictor and it ran lean so I went up to 125's...I would say it's right on the money. BTW while your swaping out the stock mains add the 40pilots and the bike does respond ALOT BETTER over the whole entire range

Apparently Suzuki did do this on non-US models for a few years Srinath.

Quote from: MarkusNIf it's the same as in Europe, standard would be 122.5 / 125 main jets, third notch.

The different jetting isn't all that weird. Remember that the firing sequence of the cylinders is fire-fire-exhaust-exhaust, so one cylinder must suck its air in right after the last one has basically "emptied" the airbox, so conditions are not symmetric.

Suzuki did this onyl for a few model years, though.

Thanks Jace009, I will go for 125s.

Cheers

Hey Conrad... I am not saying they didn't do it... I have seen it in my Manual too that some countries had different jets in left and right carbs, I am just saying on a V twin it makes sense, of a GS it doesn't... and its wrong... as in right from wrong... sense of wrong... wrong in the eyes of god... that kind of wrong...
Cool.
Srinath.

Ah!!!! that type of wrong, bit like the quality of the front springs Suzuki fits as well  :guns:
