  1. If you have the RB Racing module, you can register the unit with Dimsport & download the control software. If you meed anything special you can email Dimsport & they will help if possible. I got my rev limit increase that way. I'm currently running 14.2/1 AFR via my MTB wideband 4.9 O2 sensor.

  2. Ah spring arrives in the Netherlands 👍 Finally got my VFR back together yesterday & was going to take it for a shakedown ride today. Then had a strange thought & checked its legal status, no Tax or MoT ☹️ So have to take it for MoT this week before I can get it taxed. Typically the weather forecast for the next 2 weeks is rain ☹️

  3. I have a carbon heat shield, which I backed with alloy from a disposable baking tray ! 
    This is an early pic from 2012 with the old exhaust.

    You can see the Blue brake hose, goes over the cushion & into the square hole in left side of the swingarm. Comes out the drain hole underneath just in front of the eccentric hub to the VFR400/750 rear caliper ! 
    I fitted a bleed screw banjo bolt to the M/C to make bleeding simple. 
     

    This is it from 2016 with TBR exhaust & mini reservoir on the M/C.

  4. UK mates FJ for sale  not used for a couple of years, was a garage queen for last 15+ years that I've known him. Needs  the carbs attended to. Located in Clevedon South West England. No reasonable offer refused he wants it gone now he has given up bike riding. Message me for contact details if interested. 
     

    Yamaha FJ1200 First registered 20/03/1988

    Black - 1188cc 

     

    I acquired the bike in Oct 1997 - The speedometer has been changed at some point before I purchased the bike as it is in Kilometres and is showing 27444

     

    I have been a fair weather biker and only covered just under 9,000 kilometres in the time I have had the bike. The MOT expired in April 2022 and the bike has not been used since.

     

     

     

    All the best

  5. The nut on the end of the wax unit op rod, sets the SV position relative to the wax unit temperature. If the wax unit & its lever brass bearings are operating correctly it should NEVER need adjustment. If the wax unit is NOT operating correctly you can adjust this nut to compensate, but it may not cure your issue. If I were you I'd measure the rod protrusion length, then remove the nut & brass bearing & clean it as it looks like it may be corroded! Reassemble after cleaning & test again. 
     

    All the wax unit does is push pull the SV (choke) lever based on the coolant circuit temperature. When cold it closes the choke to make the AFR rich, when warm it opens the choke to allow main air control for idle to be by the SV/throttle plate idle screw setting. So if engine cold idles as expected (2-2.5k/rpm) then increases rpm when engine reaches nominal operating temp, the wax unit/SV plate is NOT returning fully to the Open position. The ECU does NOT have a monitor for WAX/SV position, but does have an engine temperature monitor for AFR compensation, hence the high idle speed.

  6. Sounds like he means the ignition would not turn off. Kill switch will always kill an engine. Flattening the battery is normally a stuck relay keeping a circuit energised. Attach jump leads from a car to bike battery, start car & then pull every relay out of its socket one at a time, there are only a few. You can short cut this by pulling the circuit fuses one at a time until ignition goes off, then you'll know what circuit relay is the likely culprit. Have fun.

  7. So here is my electric water pump installed.

    Second pic shows main coolant flow with Yellow arrows same on diagram.

    1706984605064blob.thumb.jpeg.6136d0391ada1669935a2acde917e17e.jpeg

    Orange arrows show T-stat (Thermostat) circuit that allows heated coolant from head to be circulated by the water pump to the T-stat until warm enough to open the T-stat. Once T-stat opens main yellow flow takes over. 
    1706984623764blob.thumb.jpeg.57f9112ba2ca855c34aac66865603ef6.jpeg

    Diagram shows location of my 25mm to 11mm (IIRC) T-piece hose joiner in the lower rad return hose to allow T-stat to be retained with the electric pump which only has an inlet & outlet for the main flow. Not a perfect solution but it works. 
     

    Hope that all makes sense 👍

  8. You can either buy the 98-99 parts, or if you look at them you can see its a simple bracket to hold the end of the cable & if you remove the wax unit you can make a bracket for the cable & attach to the same point as the wax unit mounts & choke lever. Then you can order the 98-99 choke lever. The 2K's have a blank plate on the right side of the left switch gear, but the rest is all there. Same part may fit from other models like CBR600 etc as a lot of Hondas from that tome used the same switch gear. 

     

    My wax unit was working fine before I upgraded the engine, then it would take choke off too early at too low a temp & bike would die at idle. Now I can keep choke on until temp reaches 60C & then it's off & all OK.

  9. I was referring to the left side of the bike rather than the wax unit. I'm fairly sure that flow direction is immaterial as it's just a heating circuit. I replaced mine with a 99 choke cable setup, best thing for them IMO & just ran a hose direct from left nipple off take to the thermostat nipple.

  10. The wax unit appears to have a hose on each nipple, so I assume you have the loose end of the left side one in your hand. It goes to a nipple on the top of the left side engine coolant intake stub in the edge of the left side V of the engine. 
     

    The other hose goes to the thermostat housing.

  11. Not really required. I added temp sensors to the cooler lines & the VFR does not get that hot to worry about. The cooling system can get warm, but not too hot if everything works as it should. A simple tip for anyone in a warm

    environment is to reduce the anti-freeze percentage, as it is a poor coolant & distilled water is an excellent one ! In UK summer temps 20-35c mine runs @ 75-84c when moving.
