Hello and welcome to the KatClub! I understand your question. What I'm curious about is the "without breaking the bank" statement. Do you mean less than $100? $500? Personally, (and I own a Kat) I wouldn't spend a whole lot of money on a 7-year old bike. This is not a cut!! I love my Kat. It's a 3 year old bike, and I've already spent approximately $500 on performance mods. (Not to mention the $50 for the super cool smoked-out windscreen, which adds 5 horsepower
) I've got a full exhaust system, different carb needles and an ignition advancer. They've helped a whole lot, as far as performance is concerned, but in retrospect, I'll never see a penny of all that money when it comes time to sell it.
If I was in your shoes, I'd go up three teeth on the rear sprocket. Get a complete tune-up. Valve adjustment, plugs, carb sync, and go have a whole lotta fun. If you happen to have the $400 or so for a complete exhaust system, I'd sell the bike and use the $400 as part of the down payment for a newer bike. I say this because I know that my bike is no longer worth (to the damn insurance company) what I've put into it. Too many folks underestimate Katanas. No, they aren't Gixxers. Don't get me wrong, a Gixxer is my next bike, but let's face it; most ( maybe 70%?) of all Gixxer riders aren't man enough to admit that they don't have the ability to access all of the Gixxer's potential. Heck, I've been riding on and off for 16 years and in my opinion, have only maxed out my bike's capabilities maybe a handful of times! I smoke people in the twisties, but get beaten, sometimes badly on the straights, so folks assume that the Kat is a dud. I know better. Enjoy your bike, it's a good one! Cheers!
