    I just purchase a early 83 XLV750r (Vin 238) although has not been delivered. I am looking for suggestions to remedy any known problems inheritant with the bike. Better oil, modifications etc. It has been represented as having no problems, and if true I would like to keep it that way. The bike has 14K KM on the clock. Any and all suggestions would be appreciated. Also looking for suggestions on hard saddlebags that will work with the bike.

    Regards
    Michael USA

    She is fairly maintenance free.

    -The CDI exciter coils will fail at some point in time. You can have the stator rewound or exchange against a battery powered Ignitech unit and just keep running the old stator.
    That unit gives you a whole new engine, snappy and responsive!
    http://ignitech.cz/en/vyrobky/dccdip2/dccdip2.htm

    -Some red engines have problems with 3rd/4th gear failure. $$$
    -The suspension is crap. Wilbers in Germany have rear shocks and fork springs readily available.BIG improvement.

    -I mostly use 20w50 engine oil, mineral or synth, doesn't matter. On my last summer's ride (8000km in 4 weeks) she used 250 to 300ml/1000km.

    -She feels well when you put in 3.3 to 3.5 Liter after an oil change.
    -The oil check procedure Mr. Honda describes is useless. It's a dry sump.
    This procedure works well:
    BEFORE the first start of the day sit on the bike and keep it level.
    Unscrew the lower dipstick, wipe it clean.
    Insert but do not screw back in. Pull out and the oil level should be about 1 to 2 cm ABOVE the max. mark. Then you're good.
    Don't bother checking the upper dipstick.

    -Do not rely on the tank reserve. It's a weird construction. On some bikes it works, on others it doesn't.
    In order to find out how much reserve you have you need to run her dry and have a jerry can with you. There's the secret reserve in the right hand tank wing, of course.
    Like in the KLR650 some petrol remains in the right tank wing which can be used in an emergency (miscalculation on an Italian motorway...) by leaning her all the way over to the left side, rocking back and forth a bit (500lbs b!tch #*!"). Made it 8 km to the next station.

    -Tyres
    She came with Battlewings when I bought her. Didn't like them in the rain, felt kinda scary. Then I had the idea that a big a$S enduro needs BIG knobbies, so I mounted TKC80.
    Looks bada$S and is great on gravel. Since I ride her 98% street I now use Conti Trail attacks, they stick like glue in the twisties.

    -Melvin has steel braided brake lines in various colors.
    http://www.melvin.de/default.aspx?compPI=380&compCG=M&compEID=353&CT=1&TY=2&ST=2

    -Front brake pads are TRWs MCB512 or EBCs FA069.
    -Brake rotor is a TRW MST205 or an EBC MD6044D.
    -Rear brake is a TRW MCS821 or an EBC H340.

    Maintenance manual and parts catalog are available as pdf.




    -Hepco & Becker have a pannier rack for the XLV but that is made of unobtainium, so I modified one from a GS500. Took a little welding and cutting/drilling of bushings.

    Fuel Tank repaired.

    Got the head gaskets from Switzerland, once the heads were off looks pretty tired.

    Now I need to source some 1st oversize pistons and rings.

    Any suggestions?? :dunno

    Anybody seen an XLV with upsidedown forks? The originals do flex a bit, might be interesting with a decent set of USDF and a 19" with twins disks?

    PM me if you are looking for a source

    Also chatting with Staintune about a run of exhausts for the XLV750 too.

    Let me know if you are interested. Reckon there will only be one chance :deal

    Hello,

    I drive normally most in the city .. sometimes on a ring road with us where you can not go quickly .. (I drive quite well-behaved)
    Yesterday I had a dozen kilometers on the highway .. no problem I can do that .. but now I noticed that at 100km / h there is almost no more gas left .. So if I give full throttle than I eventually go 120km / h but I it take some time to get there.
    The raising is fine just as it should in my opinion ... but the speed seems to be gone ..

    In the past also had a XLV750R and I can them to me Remember that the 140km / h was no problem ..

    Does anyone know what could be wrong with it???

    regards,
    Jody

    The only way I know is to pull the carbs and have a look at the diaphragms, sometimes the holes take some tracking down look carefully.

    Yoo need to go back to basics and follow through, check battery and go from there. If the battery has enough power/voltage then follow the power through until it stops somewhere. Sounds like the battery not enough guts.

    Interesting the new twin by Honda is about the same weight as an XLV but chain drive, shows to go how far ahead of it's time the XLV was.

    Hello Guys,
    I need help!!
    Mine bike's battery is not charged when I drive...
    I checked the battery and he is fine (four months old)
    I replaced the SR (rectifer/charger) and still it is not charging.
    Measured the dynamo resistance and this is 1,2 Ohm between all the yellow wires, and 1 Ohm to the frame/gnd.
    Measured the outgoing voltage from the dynamo ( I did it the first time but the multimeter was on the wrong scale) and I measured 12,5VAC @6000rpm....
    How can I fixed this??? And what do I need to fix? Rewinding the coils??? Changing the magnets?? What I am clueless at this point........

    Regards,
    Jody

    Got a couple more questions if you don't mind. I need to rework the carbs, what carb kit do you use? and where do you find. It is apparent that I will not find in USA, but have heard the gaskets and float needle assembly are the same has a lot of the VF 700/1000 models. Also what Weibers shock did you install the 540 series or 640 series. Also looking for air cleaner replacement as well. Thanks, I appreciate any help. Mike Oh would like to touch up swing arm paint …have you found a good match for those parts.

    Having the parts catalog is imperative.You can then just enter the part# into the search engine.
    Carb kit is 16010-me9-671 and still available at partzilla.
    Float set 16013-mb0-671,
    Float valve set 16011-422-004
    The air filter is a bit tricky. I think Tim has a solution. There are two versions of air cleaner, which one do you have? The stand alone unit or the one with the outer foam filter?

    I have the 640 Wilbers in the XLV as well as the GenII KLR. Love them. Thinking about putting one in the XR as well...
    There might be another rebate event this year which would save you up to 28% on shocks and fork springs when ordering in October.
