    Yes, the three common colours for FKM (Viton) are black, brown and green. When this elastomer became popular the de facto standard in Europe was green and in the US, brown. Our fuel seals for Mikuni BDST are black but as I proved in another video it is the real McCoy. https://litetek.co/MikuniBDSTFuelSealViton.html Took us years to get those damn things perfected. Required a three piece mold.
    Black FKM is pretty easy to spot because it is more of a dark grey than a glossy black. I'm pretty good at telling them apart by smell too.
    Since we try to sell everything you need to restore your carbs, I think we have a responsibility to help customers complete the job successfully. A comprehensive guide is really needed because they are tricky little devils.

    Back in my day Viton was always Brown or Violet.. Violet was mostly used with Skydrol (Synthetic brake fluid).
    This was in the Aircraft industry in the 70's.. last 2 years of my apprenticeship was in the Hawker de Havilland Hydraulic shop.
    You will find most valve seals in Viton are brown as well.
    I guess going with standardised colour makes it easier to use different suppliers etc without having to pay for colour changes etc etc..either way the LiteTek product is the best on the market.. regardless of colour.

    Mostly kdx200 stuff, but I do have 4 of them. Turns out the 2 old bikes that had sat around for who knows how long, do run. I had to borrow a KX125 flywheel and stator, CDI and coil off the later KDX, but they fired up. Already sold a motor out of one before I even started it. The question is: which of the other 3 don I keep?... First world problems.

    After checking the dimensions on my blast cabinet I realized the Bunnings dolly wouldn’t work so I grabbed 2 of the Aldi units... now I need to get the 75 x 75 uprights (Bunnings) and then screw it all together, plus make my own cyclone and maybe find a smaller less powerful vacuum...or put a regulating valve in the vacuum line so the gloves don’t stand out straight when the vacuum is on...
    I might look at Jaycar for a simple motor speed controller as well...that way I can slow down the vacuum for a neater solution...

    Had to cancel selling the KDX engine, discovered the gear shifter is bent, and the other was near bald on the spline. That was the part he most needed. Oh well. And I bought parts for the KDXs, too.

    Had a quick look down the plug hole of the SRX engine and she is nicely polished and looks to have plenty of clearance.
    Looks like I will do the top end on it. Reco’d head and my original barrel with stock piston ( honed ) and new rings.

    Finally collected my CB250 from Dubbo... well from a property 30km North of Dubbo. Put it on the trailer after looking at all his interesting bikes, Cars, multiple Kombi's in various stages of either repair or disrepair.. not quite sure which it was to be honest.
    He did have an absolute Cherry CB400 exhaust which I have made him an offer on.. hopefully he decides to sell it to me :)
    He also had an old Drag bike.. (should interest @Frankster ) that is fitted with a Supercharged VW motor... I will try to find some more details on that.. it used to run pretty hard a Castlereagh Drags apparently and when it closed they parked the bike in a shed..
    Anyway.. I had a slight issue when a strap broke while I was still about 20km from Dubbo.. lucky it was on the back and I saw it brake while glancing in the rear mirrors... I jury rigged that till I could get to Bunnings at Dubbo to buy some more..
    Firmly strapped down (4 straps in all) the rest of the trip was a doddle..
    Its interesting.. I initially thought I was buying a G5 CB250 but... my investigations since I got home show it to be a K5.. not that there is a great deal of difference really.

    Nice work Andy. The Blown VW Drag bike would be Rick Thornley's old top fuel bike. I think that bike originally belonged to Stan Pobjoy. Blown VW powered bikes were popular back in the day. A nice piece of nostalgia there. The guy should sell it to someone and let them run it! Nothing worse than history sitting around gathering dust.

    found my gopro in the garage today, so I charged it up and took the T500 for a spin, I will get some better mounts for future footage, I am having so much fun on this bike.

    Plan to start the Honda soon, so need to do a bit of wiring. Started on the RH handlebar switch. cleaned all the contacts with a scotchbrite and attached new wires. I will put a relay in the ignition coil circuit so no need for heavy gauge wire. Have to get some plastic primer next and see if I can give the switch bodies a new paint job.

    I bought a Zxr250 parts bike a few weeks back , it was clear title and after some tinkering, she ran quite well so today I set about fixing her up so someone can enjoy it

    It is coming along nicely

    Good question ... I was thinking about that myself if the thread stripped or yes came loose and just turned

    This is what they look like 'inside' when crimped so I guess maybe u could drill them out with the right size bit

    You need to either drill them out or use a carbide burr in a dremel to grind/cut them enough to remove, you might lose it inside the frame if it's boxed tube too.

    Have you tried tightening them ?
    Screw a high tensile bolt with a nut wound down the thread a bit into the nutsert with a washer inbetween the nut and nutsert so there's about 10mm of thread screwed in, then do the nut up tight against the nutsert.
    The way they're fitted is similar to a pop rivet, so the nutsert is compressed into the hole.
    Some nutsert's have a smooth compression area so they dont grip as well

    This is the better type

    Drill out with the same size drill you used to put it in with. If it spins just hold the head with pliers/multi grips.

    I haven't gotten much done lately, like for 2 months! However, I've picked up a couple of extra bikes and such.. Most of the stuff I've been doing has been on KDX200s (I do have 4 of them), trying to sort some to sell - 4 might be more than I need. The H model is an American import, not registerable, so I'm preparing it for sale. Engine got rebuilt, frame got paint (subframe black, sprayed with a degreaser gun from one of those cheap kits), got steering bearings and linkage bearings to fit, in the middle of a front brake clean up (the rotor is hollowed, too), and I'm sure there'll be surprises to come...

    I got around to whipping the rocker cover off the $10 CB360 motor after taking the Boss out for a nice Valentines dinner :)
    So apart from getting the Points cover and points backing plate, it looks like the rocker arms on this one are still in pretty good condition.. as are the cam lobes... cant say the same for the bearings though.
    The cam coming from the USA has good bearing surfaces from the pics so I might get away with it all.. the other good thing is the valves are still in the head.. the springs have a little surface rust on the exhaust side but they should clean up ok... so far this $10 + $32 freight engine has saved me approx $250 in used parts that are hard to find... if nothing else is salvageable I am pretty happy.. who knows what the gearbox will be like (identical between 250G5 and 360G5/ T). I wont know that for a while as I need to get the SRX finished... :)

    I might need to pull a few bits off both engines and send them up to @kiffsta for some Water blast loving... It is easy to pack up the bits and send of via E-go Couriers..
