    Some close up pics of the battery box mount on the frame would be appreciated as well.

    So, does anyone know if the hrc cylinder is niskal coated or not. I did ask in another thread but never got a definite answer. If i need to change rings id need to know.

    The earlier (production) ones were nikasil. Pre-1990 or '91, from memory. They were popular with desert racers as they transferred the heat more efficiently than a liner. I'm not sure I understand your HRC reference, that's Honda's specialist factory race shop.

    There's some stuff on doing it in an old issue of AMCN where a description was given of the build for John Hederic's Safari-winning XR600, the work was done by Pip Harrison and Nick Dole. They substituted an older nikasil barrel for the new one.

    Thanks for the reply Godsilla. Ive got a honda hrc power upgrade kit on my xr600 ('91 kit on an '89 bike) but was rushed at the time of the rebuild so i didn't think to check for the nikasil bore.

    He’s referring to the nh4 hrc cylinder available for the 600r. It bumped capacity to 628cc

    Put the battery on top of the air box

    Swinging 3-4 of battery off the subframe at rear ain’t greatest

    I am sure they would have been nikasil. It has better heat transfer and weighs less. If a factory team are pulling down a motor after ever race they don't need the durability of caste iron. I have a few stuffed nikasil barrels but I simply don't have the confidence in the local coating application companies to be able to reproduce a factory barrel. I think a cast iron liner is better for old school blokes like me.

    If you have the Clymer manual M221 for the XR600R and XR650L there ares some pics on pages 16, 45, 46, 71, 205, 208, 216, 217, 224, 225
    Also use one of the online fiche look up for parts diagrams.
    It appears to have a small sub frame mount for the battery box with a fuse panel included in the plastic box

    Planning on putting the reg/rec there, as not going to weld on the oil tank.

    Wouldn't a welded on oil tank act as a brace as well? Just asking......


    --------------------
    EDIT: I just figured out what was meant. You don't want to do any welding on the in-frame oil tank. I read it that you had an external oil tank you were needing to fit up.

    Yes it would, if an extra oil tank was needed, but the one included in the frame is sufficient.

    Fortunately, my XR doesn't use that much oil.

    I think weld on mounts to oil tank is great location as act as a great heat sink

    when fully heat soaked I'm not sure that tank would absorb heat away from 'what ever' he's gonna put on it.

    The XRL's reg/rec is mounted on a bracket that is welded to the frame behind the steering head. To save welding the bracket in a similar place, I'm going to put my reg/rec under the seat. I will weld the mounting points on the frame to mount the battery, in the same place as the XRL. Going to use the XRL battery box, airbox and sidecover to make it look pretty, plus it gives me the mounting points for the start solenoid and CDI.

    That's the plan anyway.

    NX650 barrel porn. Bored to .5mm oversize. Trick of the light has the cross hatch looking non existent, but it is correct angle.

    As I will be using the XRL battery box, I have to swap out the XR's airbox in order to use the XRL's sidecover.

    Nice score from the US, 2018 XRL airbox.

    Does anyone know if the right sidecover is interchangeable between the XR600 and the XR650L?

    Here's mine with stock wiring and silicone insulator below the unit, no need for a lightweight lithium battery to be moved from the rear of the bike, there is no point for a non racing ADV bike.
    I love cable ties too! Main wiring loom just needs some flattening and wriggling until you are happy nothing will chafe.

    Seat mod with sidecutters and heat gun for more airflow over the mosfet and to avoid sucking intake air from the right sidecover dust cloud. Excuse the shitty photo but you get the idea, it works fine and takes a few minutes to do.
    The reason for keeping the plastic flap is to stop water running down the seat curve into the air intake.
