omg work done!
Great weather for pulling the runner 180 out of the shed and trashing it.
Pity the runners water pump disagreed, typical.
€99.99 inverter welder from lidl, always wanted one, fingers crossed it’s not shite.
See that roll bar? entirely full of water. holes on top, no holes on the bottom.
Did get the tub off finally, all things are in a terrible state, so what ever happens next landrover types will be offended anyway!
large and late update
first up the runner:
the seats great isn’t it? yes the rest of it is falling appart but who needs it? ebay front brake calliper is in terrible state
took it on the two stroke only run to the kilumney bike show:
It was the tzr125 that broke down, I totally got away with it!
cub 90 racer has successfully survived the paddy dakar, wish we could change our race number to 21 and go to mondello like this.
gotta strip the engine down for the compression increase, can’t leave the mud on it for that.
run run the runner
New expensive jolly moto pipe! (correct one this time!)
Piston looks good, nothing untoward on the back wall of the cylinder either.
Old pipe leaving much rust behind. i’ll patch it up for a backup pipe.
Ye hardly notice the mold, cob-webs and rust, when you have a JM pipe that’s worth more then the bike.
Storage spot, hopefully pipe will last longer if i keeps it shiny.
Whipped off the belt cover and polished off the rust on the rear variator, check the oil and water pump, there good but the toothed cog that powers both is quite wobbly on the shaft, better get a new one.
After spending ages trying to get the air to stay in the front tyre, I made it to the petrol station and back, brakes are worthless,suspension just totally not there. ticking over at 80k/mh. nothing blew up, excellent.
So i’d better fix them brakes,sorta might need em. Much lube and fettling later it was time for some brute force. I fixed them so hard the caliper is now utterly shot, off to ebay! and that godsdamn slider is still stuck in there to boot.
bikes in ditchs
Most of my bikes are safety stored in the ditch, no idea how they’ll survive once i have my own shed. buggers will probably never start.
take my runner 180
fork chrome shot, rubber on the filter of the kart airbox cracked, seats a bit buggered, front wheel (not the tyre) won’t keep the air in.
kick it over a few time to fill the carb with three year old petrol, clean the rust off the plug, started third kick. no sweat.
This? not really a problem, pm55 on the way! moar power!
pm55 won’t come with a silencer, but i got loads, dug this short one first, its a chamber type.
The carbon one is from a aprilla rs125, straight tru. worst looking too, so it’ll look just right.
Found the tzr250 anti-rocking bar, gotta repair the engine cases where this bolts to first before i mount the rear part.
runner airbox mods
The mount i made up for the kart airbox on the runner, i knew wasn’t a perfect engineering solution, it was only secured by two points, and both those points were aligned in the wrong plane (up and down). So, i welded up the cracks again and added a strap.
Worked well, very stiff, can put alot more weight on it
The extra bracing on the upper part is a bit redundant now.
Did i mention i brought it to a dyno, and it made 2bhp more over stock? doesn’t sound like a lot but it’s a round 8% moar power!
Just needs new tyres and to solid mount the engine, think i should get a 28mm carb and chuck the 24mm on the tuk tuk. Shopping!
the new year
Well the stephens day classic run went great, i didn’t break down, i got a go off of a dt230 and i avoided the rain. On the other hand the damp road flung lots of crap about the place and i fecked up all the photos i took.

you can look at the shots anyway on my mums picasa album.
mucky jacket:
Even got some in the airbox, got that cleaned up and installed some lighter rollers again since the jetting feels spot on.
Treated the scooter to some duck tape.
Had a quick spin into town today, massive improvement in acceleration, must get a proper pipe one day. fuel consumption is as bad as ever at 7.55L/100km, that was at the classic run, it’ll probably be worse now with the lighter rollers.
Jobs over
Made about 70 baskets and they were all gone in one night. spine is wrecked from bending over them.
This cbr6 is looking like it will never return to the road in a nice condition, so fingers crossed i get my paws on it and turn it into a dual sport for the Mongolian trip..
Today i put the 115 main jet in the runners PWK carb, couldn’t take it for a spin since i didn’t have any rain gear, but loading it on the rear brake and a quick spin on the gravel out to the back and there was no bogging and felt like there was a lot more power to, didn’t sound ‘wet’ or rich so finger crossed for the classic spin this sunday.
hopefully more updates soon, not a lot done recently.
More runner jetting
Well parts have finally come for the runner, the oko parts are much nicer (things like a proper seal on the air screw and it’s all brass not plated cheap metal) then the motoforce parts, when i get another one (possibly for the rxs) it’ll be an oko, none of this shit cheap copy of a copy of a copy.
Also fitted new fuel pipes and put a tiny drain hole at the bottom of the airbox, and went for a spin to the petrol station, took 11.33 litres to fill it, so about 11.5 litres for a full tank. after a longer spin with a 107 main jet installed the full throttle flat spot was worse so i’ve ordered a 112 and a 115 which should be spot on.
Got a bargain hayabusa clock cage, fairing fit great now, but i still need some tiny hard to find screws to finish the other side.
Great looking benly 125, first thing we talked about was how to make it something other than glacially slow. turbo rat rod bike?
oil pumps, master cylinders and spuds
Lately there has been some 3ma’s in the local ads so between myself an mick we have been trying to get a few parts together.
Turns out that mick has a spare wonky pump, that i could have for parts, great except i though mine was a differnt early pump.
Well i was wrong, there was just an extra bit of the pump stuck in the case, my pump is completely normal and it could be swapped for a 3xv one, sorted.
Bloody runner is acting up again, broke the 90* bend coming out of the top of the carb, it’s still leaking from the base gasket, the idle screw i think is still too short (26.abit mm from tip to end of threaded section) and my attempt to lengthen it failed from a dodgy aldi/lidi tap, and all the 6mm fuel lines are cracked. And it’s still drinking fuel.
The bajaj has been going well, here is the cbr6 14mm master cylinder and lever chucked onto it, the lever is very nice but it don’t fit 🙁
This is a kawasaki zrx400 rear master cylinder, 1/2″ or 12.7mm (top one in pic) much easier to mount, possibly the wrong size but we shall see soon, i’ve already paid the 100€ for hard lines and flexible hose’s to fit it all up, don’t have the pic of the final bit of welding to mount the master cylinder but it’s done. Just need rear brake lights and a few more wires soon.
Karen, a true irish cat wondering “where’s the spuds?”
Stuff done.
Well started fine tuning the runners jetting.
My pwk 24mm carb has:
Needle      JJH
Main jet     110
pilot        40
slide        3.1mm  tough to measure this
float height  18.8
Air Screw   2 turns out
The pilot is way too rich, at quarter throttle it’s four-stroking like mad and quarter throttle is from 0-80kmh, couldn’t find a 38 jet online so got a 36, may have to put the air screw out one turn, rather then an optimal 1.5, but with a 36 i should be able to get at least an idle.
Also found an injection kit which seems to be built on microsquirt, very interested.
Not much done to the bajaj, tried to get the drum off to check the brakes, didn’t wanna come, so i assume i need a proper diagram of how the front is supposed to come off or it’s rusted on. Got the wheel changed tho.
Busa tank is ready so got started on the fairing, rear posts for the light needed trimming but no other faults yet.
Nice ain’t it? you can see the hump paint don’t match.
