Kart airbox, runner 180
well the airbox turned up, massive ain’t it?
got a free kart steering wheel cover as well, now if i just had a car to attach it to…
me thinks i have to attack the airbox with a heat gun to make it fit, and also probably get a filter with a straight neck.
there are so many thing i have that just need a little bit more work to finish off, i’ll never get anything finished in true timmy style..
Tzr250 3ma
Definitely going on this years honda 50 ring of kerry  challenge, the race bike just needed a comfy seat, the gearing changed for the hills of kerry and the front brake cable needed a bit of oil. 116 miles on a honda 50 and about 100 more on the cbr6 just to get there 😀
Since i’m waiting for other bits though i’d do something to the tzr. glued on properly the tank rubbers.
the seat is missing something, got the rubber bung from an rg125 seat, which fitted perfect except it took an m6 bolt instead of an m8.
found my rx135 engine, it’s in the red box…
should i ring that number?
Runner 180, kart airbox
Busa looking well!
rxs100 head badly modified to fit a rx135 barrel, may have a go at the rxs again soon.
oko pwk carb with filter on that doesn’t fit.
if the tyre was new…
test spin! nothing fell off anyway, didn’t open her up, needs more running in, the noise from that filter is unacceptable.
it rubbed, su-fuckin-prized?
think i’ll make it fit the bajaj.
So i’ve ordered a lamellar kart airbox from superkart.it, they had excellent dimensions. should be here in two weeks (back ordered)

this one was also considered, bit its a little odd shaped.

Runner ready? ish…
Anyone remember this?
Well it’s been put to a good use:
fecking awesome no?
then i had to ride this thing around a bit to check it’s all working after a rebuild. all good,some more gearbox oil and then have to do a bit more testing tomorrow to make sure it’s good for competition.
Got further along with the runner 180, glued in the autolube nipple, nipple it self is rescued from the old delorto. Last time i did this i glued it in with epoxy this time it’s only held in by superglue, we shall see how that turns out.
must protrude into the fuel/air stream.
Top end complete, never checked the whole barrel height after murphy engineering skimmed it, but it only took one 0.4 gasket to make the squish 0.9, the base gasket should have been 1.0 along with the corresponding hike in the ports. it’s still an improvement over standard just a small one.
cable length for the PWK is next hurdle. and i have to buy bbq paint.
Skipping the solid engine mounts for now, lets just get it started first.
Parts are here!
and well bloody wrapped they are.
PWK copy 24mm, look at the meat left over, could bore that out at a later date.
We now have three rs250’s dotted about the house…
Racing rs125, it’s actually so nice, stuff the rotax 257 in it and it would be a dream.
We have a new dog: Busa. he’s a whippet and in quite a bad state. Nothing 114 euros worth of pills and injection can’t sort.
The pictures don’t show much, he’s got mange, scabies, pressure sores (we hope!) and his tail looks like it might have to go. If your brave here are some before pics :
https://picasaweb.google.com/maireadomullane/MyNewDog# in a months time there should be some much better after pics.
In other news, i upgraded the laptop to ubuntu 11.04, holy shit it’s useless, what the hell is it these days with replacing simple text with unintelligible icons? i know it a beta and all that but i can’t stand it, didn’t mind when canonical first swapped the window management buttons around it was actually a good idea grouping more of your controls in the upper left of the screen, but this is jump in the wrong direction. So all my computers are finally debian now.
Nope didn’t start.
Chopped out a notch for the cable run. and that was pretty much all the hard work done.
Decided on a smaller seat, makes it easier to grab thing like the handbrake.
with the glass in there i think it’s gonna be a little tight.
The 8 m10’s i bought to bolt the body down were too big, so i didn’t. Monday i’ll get the proper m8’s
Did it start? no. carb is all gummed up from running upside down and frankly i’m bushed from working on it all week.
clean carb.
test spin by jamming into any gear.
weld in seat
figure out where to put the feet
then sort the brake pedal and the gear change.
close to test drive time
More done, headstock is all welded on four sides now.
chopped a few barely hanging on rusty panels off.
channel cut out for the start handle, not pretty but strong.
tested the handle to make sure it didn’t catch, flipping engine started while upside down! must sort a kill switch.
figured out that vespa’s don’t have a positive stop gear change, thats gonna be a right arse to fix. Tomorrow (if i can find first gear) its definitely test drive time, even bought new bolts to screw the body back on.
bajaj handbrake
been rolling over myself pushing the bajaj around checking the front brakes 🙂
Now i can pull it up with out banging my knuckles
one more piece of welding done.
that cat is badass, i just went in and called all three dogs wussies for catching only one rabbit between em.
excuse the wierd pic size
bajaj, whats left?
gear change
rear brakes
channel for starter handle
channel for cables
seat
put it all back together. i’ll do it tomorrow.
Rolling wreck bajaj
First the brake pads for sarahs car turned up. so i did those.
Thne i began to think “A pm55 is cheap if you can provide your own silencer” so i must find out the pcd, the silencer bwlow is off an aprillia rs250
This rd350 turned out to be a bit of a dog underneath everything, 250 barrels (rebored and ported) house hold wiring zip ties and broken bolts along with dead mains, then again is is 30 years old.
So finally got started on the bajaj, mounted up the fuel tank, must sort a knob of some sort to turn the tap.
then whipped the body off to get at more cables.
so far the front brake is in and the handbrakes. the clutch is also in but the sheath needs shortening/attention before it’ll work, choke is done, throttle I was about start with but then i ran out of time.
Whats left? gotta cut a chunk out of the body for the cables to pass through and a small section out of the frame to allow the starter handle to work. Find some bolts to hold the body on and lastly engineer hydraulic rear brakes a foot gear change and, of course, a seat.
Why a runner blows up.
The root cause was the water pump not being turned any more, weather it was the bolts falling out of the oil pump causing the wheel not to engage the pump or the wheel wearing out then the bolts falling off the oil pump I’m not sure which happened first. Parts are on the way anyway from http://www.psntuning.co.uk/ should be here next week.
rotax 123 barrel on runner 180 cases? i wish
I Will get this thing rolling tomorrow, i must!
In anticipation of fiddling with the carb i’ve put back in the standard 15.5g (i think there that weight anyway) rollers, slower ratio changes make it easier to diagnose problems.
