    The previous owner of my XL600 spruced her up a bit by painting the engine and other parts black.Engine looks good,but he also painted over the carbs,battery,wiring etc. I know I have to get that paint off the carbs,but what about the rest of it?Is it ok to run her with everything covered in black? Should I replace the wires? She runs fine and makes no strange noises.

    you can actualy leave it on everything it wont hurt anything.....may not be the prettyest but t certainly wont hurt anything...if/when you want to go stripping paint citri strip is what i would use on the carbs..the engine imo would be best left alone unless your rebuilding it.....the wireing forget about it....as for the batterybox etc citri strip is fine on it too...i used it on my entire xl500s except the engine..someone had tryed to camo up the bike very badly

    I spend no time on this thread and am not up to speed on the XL600 bike but I have a idea that might work with some of your help.

    I purchased a 88 NX650 Honda ( this makes my third ) but it has been greatly altered suspension wise, ugly, and it is Titleless but the engine is fine.

    My question is will a NX650 engine fit in these XL600 bikes? I am sure someone here has tried this so I'm thinking rather than spend time and energy solving the NX issues I may look for a trashed or dead XL600 and put the NX engine in it? Anyone need a set of WP Extreme forks and KTM wheels for their XL600?

    Your thoughts would be appreciated.

    I love the looks of the later XL600's in white, it would go well with my Transalp. Thanks

    No at least not the top end. The XL has two carbs that are spaced apart and in that space the rear shock goes through, right in between them. The NX engine or any single carb air cooled Honda single the carb is in the middle and will be in the way of the rear shock when fitted in the XL frame.

    But
    with a special made Intake Rubber that mount the 2 XL Carbs on a single Intake RFVC Head you can fix this Problem.

    There are ways to scab together adapters, but it's all likely to perform worse than either OEM setup.

    It will if you mix and match a bunch of parts, but is otherwise not a direct (or easy) fit. You would need to put the XL's entire top end on the NX bottom. Then comes addressing the electrical system to accommodate having only an e-start or use the XL's kickstart parts in the NX, which means splitting the cases.

    moddifying for E start only requires 2 wires to a button, a start relay and a wire to teh relay and off the relay to the starter...so thats simple enuf...

    anything will fit if your willing and capable of going the extra mile

    The NX has the same engine mounting points as the XR650L (all years) and the XR600R ('87-on, I think), and it should just be a bolt-in substitution on either of these bikes. The carb is the same with the NX and XRL, but intake routing is slightly different. Outside of the engine, nothing much else is compatible between the NX and the other bikes.

    If the Adapter is well made then its most of the Time the new Engine or the Carbs are not correct ajust that make the power worse .
    Air flow over two seperate Intake Ports is different to the Airflow over 1 Split type Port .
    Carbs need to ajust for that .

    Did Zombiestomp do some kind of single carb conversion a while back to his RFVC?

    It seems like he did but I'm not sure.

    At one time, I had an XR650L engine in my '84 XL600. I used a 38 mm Mikuni flat slide carb with a universal Uni foam filter clamped to the carb. It worked fine. The filter did rub on the shock spring though.
    The Mikuni barely fit between the tank and frame. I'm pretty sure the stock XR650L would not fit.

    It had an XRL front end on it at the time as well.

    Here's my $200 basket case XL600. I repainted the tank with an Elsinore theme. Some top end work, new cam chain and intake valves, thats about it. I can start it on the 5th kick (no decomp release). Torque like a John Deere. But too big and no electric start for trails riding. So this will become a retro-motard as I now have an 04 DRZ400E as my trail/dirt bike.

    Well, there would be a photo if I knew how to post it.

    Thanks for the reply shortlife.I'm planning on replacing all the cables,changing the brake fluid etc.I'm going to try and take the black paint off the frame also.Hopefully the Honda red is baked on and durable.I paid $1100 for the bike and plan on spending another $300-$500 setting her up to ride. I figure for under $2000 I'll have a pretty nice bike for playing on dirt roads.

    the honda paint is fairly tough stuff but....id expect to have to repaint anyway....if you want something tough and dont feel like powder coating see if you can find someone who sells tractor paint..the international harvestor red is close enuf..and tough as nails but you may need to hit up an ag store for it

    I'm not too awful worried about the black on the frame.I'm more concerned about the black on the carbs and making sure all the cables and front brake line is good.The bike doesn't look that bad.As long as she's functional I'll be happy.Cosmetics come second.
