Thread: VFR 800, my first build

  1. #41
    Thanks fellas!

    Sadly all did not go well with the dyno, we discovered a MASSIVE leak from between the V once the bike reached high temperature from what I can only assume is the thermostat.

    Normally it's just a matter of removing the airbox and fuel rails to access the V, sadly someone, probably me, put the intake boot clamps on the wrong way when I dropped the engine last time, meaning they cant be accessed from the gap in the frame they usually are, meaning I'm going to have to drop the whole engine out to access them...

    My "That-sucks" meter just started giving a reading.....

    After many long hours of labour and much swearing, I managed to lever the throttle bodies off without removing the engine!





    And I think we've found the culprit...





    Pulled out the thermostat and little hose nipple thingies, sure enough o-rings were completely stuffed, they also smelt like shit which can't be a good sign.





    Replacements ordered, in the meantime I have some plans with fans, specifically 3 80mm PC cooling fans which will fit in nicely behind the radiator.


    Only thing I'm struggling with is how to wire them so they activate at a certain temperature now that the stock temp sensor is no longer connected. Any ideas?

    the fans circuit comes on by completing the earth. Temp sensor isn't needed.
    From memory, fan circuit is always getting power.
    the rad has a fan switch (brass threaded sensor, single spade connector) that threads into it. When that gets hot enough, it completes the earth circuit, fan comes on.
    I've earthed my rad to the frame.

    you can either put the fan switch back in the rad, or just wire in a manual override, or both.

    I've got 3x 80mm fans from jaycar on my rad.

    I've got 2 80mm fans from jaycar on my rad.
    Ok cool, I'm running the VFR750 rad which has a single pin temp sensor on the left side, assuming that's the same thing.

    How's the cooling? I reckon I can fit in two 120mm 150cfm fans which should be enough to keep the bike from overheating when stopped.

    I commuted on it, so good enough for me - I only want to use it for open road/track day shenanigans, so if it commutes at 100, open road i'm sweet.
    And yes, same thing.
    I could only fit 80's in because my custom rad is small.

    Good on ya mate, fingers crossed you don't get any more little gremlins, mechanical or inspector...

    I swear to God I'm cursed, was giving the bike a once over before the inspection in the morning. As I was checking the front wheel, the front sand slipped and the bike fell on me, breaking the right mirror mounting thread inside the bars and, more importantly, ripping my favorite pants





    So yeah, gonna need new bars and mirrors, hopefully I can get them locally

    numbers (Wollongong) is selling a set of MT09 fatbars. When mine tipped over it punched a couple of holes in the petrol tank.

    Find your own pants.

    Thanks Chris, I have MT09 bars and a set of Renthals Fat bars also

    Crisis averted!





    I managed to cut a new thread into the bar insert using a tap and fitted a slightly bigger bolt, works great but I will end up replacing the bars anyway, got my eye on a set of renthal fat drag bars.


    Also had a fiddle with the map, ended up putting it back to stock and it appears to be running much better now, suppose the extra length of my undertail and the chicken wire baffling are restricting the flow a bit.

    Just got back from a brief holiday, fitted a CBR1000rr rear master which seems to match up to the 2 pot VFR rear caliper nicely, lever feels good and solid. Also came with a proper HRC reservoir which was a bonus.





    Roadworthy inspection tomorrow, for real this time, not gonna run away for a week :P

    Sadly didn't pass inspection, apparently my headlight and mirrors weren't ok, need to be OEM not just ADR. Bike performed well on the ride there though, cooling system worked well even on a 37 degree day. However I noticed a fair bit of chatter from the front brakes under even mild breaking, presumably the calipers are in need of a rebuild or the steering head bearings are fucked.

    Thats bullshit Seb, ADR gear is compliant, that should be well enough! Sorry to hear it didn't go to plan.
    Whats the next plan for it then?
