    I have an 88 NX650, mint condition. They are a lot of fun, but geared towards a shorter rider I think.
    Anyone want to buy mine?

    strange you think that ..I'm 1.90m and never found it low ..far from it . Only concerns i've ever heard re the height were that if anything it was too tall for some riders.

    Hi folks,
    just want to know if the clutch casing for my bike ('93 model) can be swapped with cases from other years? Can a clutch case from the XR650L fit too? I need to replace mine, so any info would be much appreciated. Thanks.

    I love the look of the dual cans on the Dommie.....but ALL stock exhaust cans are very restrictive, and usually big power and throttle response killers. I'd either mod the stockers for better flow, or try and find some freer-breathing aftermarkets if any are still available. Nothing I own has the stock exhaust on it anymore :wink:

    Direct cross over. No problem. The XL600 will fit but it does have it's Auto decom lever that you don't need.

    The bike was partially disassembled, degreased, and pressure washed today. It appears to have been priced right due to the surface corrosion of the frame and all of the plated hardware. The body will require many hours of repair and reconstruction.

    That's part of the deal with a 25 year old machine that was used as intended.
    Remembering that "Nothing worth while comes with out effort" will help keep me on track with this overhaul.

    Two plans for the stock exhaust cans have been devised. We will see what is practical once they have been opened.

    WOW those look REALLY nice! - $ 750.00 plus shipping - Cool has never been cheap.

    What are your thoughts on the headers if using these cans?

    There's plenty of headers for single exhaust, but for dual cans the only option I've seen is the stock ones. Though I was thinking of getting new stock headers to go with the exhaust. The ones on it now are fine, but having nice shiny new ones would really help the look. I didn't think $750 was very expensive for exhaust; top of the line exhaust for CBR's is usually around $12 or $1500. My only concern with buying an exhaust for the NX is if it is cost effective. How much could it really improve performance?

    What ia a single muffler alternative to the stock duals? Where? Apparently no one wants to buy my '88 so I guess I'll do some modding.

    Best case with all the induction, carb, internal header welds (if there are any), and muffler can mods would probably still be in the single digit percentage of increase.
    And definitely more $ than a 14 tooth front sprocket for the same percentage of acceleration increase.

    I payed $467 U.S. dolllars for a complete headers back exhaust system on my XRL...FMF powerbomb SS header and Big Gun Evo R aluminum Silencer. $750 U.S. plus shipping does seem pretty expensive for a set of steel slip-ons. You'll get a noticeable seat of the pants power gain, but I'm not sure it'll be worth $750. The look might be worth it to you tho :dunno I payed $709 shipped for my full SS Yoshi on my busa.
    Unfortunately Dommies parts are high cost...thats the only reason I passed up on a beauty of an 88 :cry
    Personally I would still shop around more, or maybe even consider switching over to a full header-back single system off an XRL or similiar...it wouldn't be duals, but it would cut alot of weight up high, give a big power gain, still look very cool, and be way cheaper I'd think. Not sure its worth putting $750 worth of steel slip-ons on the Dommie financially.

    You could also internally open up the stockers for equal flow to free-flowing slip-ons, then get them powdercoated any color you wanted, that would be a very cheap alternative to expensive slip-ons, and you'd still get the power gain and good looks :evil
    Some of the XRL guys are doing that with their stock systems, and getting good performance results and sharp looks :D

    Imo they are not worth the money. They look nice, but that’s the only good thing about them. They are designed to meet European Laws, which means the sound sucks and the power output is rather lesser than more. The best (roadlegal) exhaust in terms of sound and power is still the original one.

    But if you donĀ“t care if your Dommie becomes much noisier the Arrow Paris-Dakar may be a choice. It’s made of stainless steel, it is light and inexpensive. And with some carb/air filter mods you may even get a decent plus in power

    I believe the headers from the XR650L will work for a 2 into 1 setup.

    They will be close but not an exact fit.
    You may need to do some pipefitting!

    i fitted XR600 headers and universal supertrapp quiet series silencer.totall cost 30euros for headers,20euros for midpipe(used) and 80 euros for new silencer.headers are quiet easy to install in RD08 frame.
    carb rejetted in dynometer and works fine.
    the only reason i changed stock exhaust is weight loss and not the power.

    stock headers(kilos)
