Doing away with airbox

[Anonymous]

I have an 83 GS450 with dual Mik's and the airbox. I'd like to do away with the airbox and just use 2 K&N filters.

Does K&N have what I need? Will I need to rejet? Etc, etc...
Thanks

Prepare for much time spent getting the settings correct if you choose this path. The rewards can be well worth it but you will invest much time getting it dialed in right.

The choice is yours...

You will need to rejet........probably something between two and four sizes larger. I would not change to pods/K&N filters because I dont have enough hair left to risk pulling out too much and dont enjoy beating myself up anyway.

I think you can tell from this and other posts that most of us have found out the hard way it's easier and better to leave the old (really) stock airbox in place. Suzuki paid those engineers a lot of dough to make a good intake system. Unless you want to experience the joys of pulling the carbs and wrestling with the air box and experimenting with getting the jetting right. If you want a way faster bike, buy a way faster bike. Buy a Bandit 1200 or ZREX or Speed Triple. That said, if you follow all the requirement for a DynoJet Stage I or Stage III, depending on your application, you can make it work fine. To me, it's not worth the trouble and expense. I'd rather go riding.

200% agreed.
It's because of my wanting pods and the stage 3 kit that I've had this bike since december and it is STILL unrideable!!

It does my heart good to see the truth about the stage 3 myth. Nothing for nothing is the name of the game.
As the others have said if you want bolt on power bolt on a larger bike

I get the picture. Thanks. :-)

Longbiker, we don't mean to be hard on you. It's just that we've all been there. The GS450s were jetted notoriously lean and even their successor, the GS500, hasn't changed at all in this regard. If you want to dink around with K & Ns (about $40 each) and a jet kit ($100 give or take), it's up to you. Just be sure you satisfy all the parameters. You use a different jet kit depending on whether you're putting a K & N stock replacement in your air box, or removing your air box and substituting K & N pods, and/or adding a header, which I doubt is available anyway but maybe Vance and Hines still has one that would fit. Don't expect much, if any, of a performance increase, though you might gain in driveability with a faster warmup. You might want to check the gstwin.com site for their comments on a jet kit. Again, though, it's a small bike, relatively speaking, so we'd all say just ride and enjoy it. When you feel frisky toy with a Honda 400 Hawk of the period. Personally, I think this would be a fun bike to cafe-nate. Put some low(er) bars on it, some nice tires, some replacement Dunstall megs, a braided steel front brakeline, and rev the pee out of it as you scream around corners !
