Christmas break work.
This scene last year was a mini glacier.
Cleaned up the 32mm carbs, fitted needles which richend the top end and left in the 210 jets.
Bastard throttle cable is near impossible, but i got it
Found a better fuel filter and slotted that in too.
Knew this things are restricting the engine and since i found out where our stash of jets were hidden, they got the chop.
Now all i need is some free time, fuel and dry roads to take it for a test spin. And to figure out where the throttle cable is meant to be routed.
The runner needs some love, so i found it a mirror

And since i got 11.42litres/100km(25mpg!! i may have stolen some fuel at some point i forget) decided to change the clutch springs, the green polini ones are great for a quick get away but i have to use plenty of throttle to keep the bike doing 50k, hence the suspicion that their causeing the crap fuel economy. Also they fit like shit which is i hope the reason for the weird shoe wear pattern.
I was going fit the old ones but I’ve lost the feckers, so i fitted the malossi race ones, which were a much more reasonable poundage and better shaped. Even managed to get em in single handed this time.
Test ride revealed a tiny amount of bog off the line and only once at that, if it still drinks the fuel it must be the rollers, which will make me sad since the buzz from the acceleration is awesome.
Back to FAS tomorrow, but at least the summers on it’s way.
In before the snow!
Just got the runner out of storage literally hours before the snow hit hard. If i have to travel the runner will be much easier to pick up after a slide 🙂
damn you ice!
busa fairings: got 100gbp back so i will try and paint either the tank or the front farings to match. eventually.
Today was finaly a bit warm. last night i put the helmet on in antipation of a ride and it felt very very good! been off the bike so long now that when i put on the boots this morning i had to resize the straps, my calfs have gotten bigger with all the walking. I’m sick of walking.
Though i’d have a play with the bike since it’s been neglected for so long, swapped on a matching front tyre, old one a completely different profile.
Gave the wheel a quick degrease, absolute pita, why did i bother?
Ice claims another hose nozzle thing.
And back in one piece, much more neutral handling, off for a spin and i break my arai’s little plastic visor lock, what am i getting for christmas? 🙂
cbr6 is it rat now?
little update to the cbr6,
been driving around for ages with out the nose, and yesterday i decided to hack it up and paint it and slap it on.
I’ve yet to get used to it, i may paint the screen magnoila too.
front edge of the right tooth is a little dodgy, an angle grinder is not a precision tool.
I like how the red flows from the frame to the nose, but a black surrounding the nose looks a little awkward, meh when it stops raining and the light is better i will take photos and plonk it on ratbike.org, pity that site doesn’t have comments, i’d be the outcast of the outcast community 🙂
Busa fairings
A big box from china arrived the other day.
Yup, bastards.
Do you see the resemblance?
Anyway, also this week I’ve been helping niki with his gpz500, here we are getting the mateing surface’s quite clean.
Then i was playing with the 3ma’s carbs, at first i was happy to see the 210 main jets, but then i looked closer.. mismatched bits and the carb icing circuit was beyond saving.
also there 30mil carbs ? should be 32mm on a 3ma1.
spares are 32mm, whew, reckon they switched to the 30mm carbs and used the bigger carbs 210 jets and a few other bits to compensate for the race exhaust and the autolube. I’ll just buy some bigger jets.
mikuni oil pump
Right sorting the oil pump leak, it seems to be coming from the spindle (which later i found out was a cam) so i figured there must be a seal on that, that isn’t working.
The plate/arm for the cable off here, can move the cam in and out a bit.
I know nobody can see it(phone cam), but this is what has happened, the top plate has a little finger on it that push’s the back of the cam in. That finger is worn quite a bit, hence that cam can come out and oil gets past the seal. Simple’s. No idea how to fix it though make another top plate with a new finger? finding a second-hand or even a new one is not easy.
grey sludge from the gearbox, No shops open today so I left it there to go find a new pump on the net. No luck so far.
Tzr250 3ma
oil pump still leaks, it had no gasket behind it but after fitting one it still leaks, looks like it’s from the spindle.
It lives! took it for a drive around the driveway then, first gear is very tall 🙂
Continuing my morbid fascination for crashed bikes, looks like this 3ma got smacked into the ground then the car keep going grinding what’s left ever further. epic.
Also the m6 rose joint turned up, so during the week I’ll try and get charlie to machine me up a proper gear lever.
Autodesk Inventor
is my new bitch.
latest:
Spent the day making a better chassis to match that nice front axle,no pics yet, tomorrow will (no more rain pls!kthxbi) hopefully go to the shed and measure up the english axle and some engines to go in.
Tzr250 3ma
Put it back together for a test spin, just to see what else it needs.
‘masing what some wd40 and a rag can clean.
Next day i’ll attack it with a new fuel filter and some premix to test the oil pump. HAVE to put rear body work on, legs would be fired in flash.
Also finally did the oil and filter on sarahs car. about a year after i said  would…
Tzr250 3ma
Had and exam today so left early and bascialy got nothing done coz I went for a spin.
modded spare airbox, hopefully that was attached to micks bike at one point and not mine 🙂
looks good from this angle.
This looks a bit wrongie, rod would have to have a generous bend to avoid the frame
bit of man glue to seal up the crack in the oil tank.
