    It's hard to shake the 2-stroke bug.

    Forgive me if I ask a silly question : I bought mine in '84....it was an RD. Was the RZ merely a later model? Or....what was the difference?

    RD was Europe, Japan and elsewhere(?), RZ N. America. In Canada, after the RD350LC in '81 and '82, it became the RZ350, with YPVS, from '83 until the final year of importation in '89. U.S. stopped importing it earlier but I don't know what year.

    I believe the US market got the RZ350 while others got the RD350LC...later other markets got the RZ. Same underpinnings, some cosmetic differences.

    Question for the RZ experts, I'm thinking of putting a set of pipes on my RZ350K I would like to keep the center stand and the chin fairing, it's a street bike not a track bike the biggest reason is purely esthetics I'm not a fan of the cigar style oem pipes, so far I have found the following:
    • Jolly Moto
    • JL, Jim Lomas
    • DG
    • HVC Cycle house brand
    • TSA, Two Stroke Addicts
    Any others I should look at ?

    These JL street pipes are my favorite so far.

    Toomey's- I believe they produce the most top end power (at the expense of low end and mid range)

    I heard that about the Toomeys would prefer low and mid range improvements over a few extra hp at 10K.

    Might not want DG's then either. Don't know what they're like on an RZ but on my buddy's RD400 the bottom end disappeared. I have a friend with Toomey's on an RZ350 and he raves about them. I'll ask him. He's not close, otherwise I'd take it for a spin and know for myself.

    To be perfectly clear, I have an '85 RZ350 Y/B KR special with a full Toomey intake and exhaust. Running the stock 28 mm mikunis, 410 main, 20 pilot, air screws at 1 turn out, neeedles set to lowest (leanest) position. It runs clean throughout the rev range. There are no flat spots and it can, and does pull the bike along below 6000 rpm. Not fast or exciting but certainly rideable. Above 6000, well the power valves open and she takes off with authority. Not exactly peaky, but possibly bipolar? The trick is to get your jetting right for your elevation. Get it wrong and you'll end up with a flat spot between 5-6000 rpm, exactly where you don't want it.

    Fyi - I have a set of cat-less Canadian pipes that I would consider selling. Looks stock, breathes much better and gives broader power characteristics.
