Prep? nope. Race? yep. Boom? YEP!
Got a three hour enduro race on at the local go-kart track, watergrasshill nifty fifty 2019Â https://www.adventurepark.ie/
So a working bike is necessary! Need this to stop leaking, first attempt with carpet tak failed to no surprise.
JB-weld that fecker.
Special sauce also known as dihydrogen-monoxide, very important for re-magnetizing over heated inner rotor kits.
spent far too long making the side cover fit, and then ditched it in the end.
Ready to go? super light weight carbon end can fell off, so a rg125f end can was pressed into service. it was very very heavy.
Had a great race, all 27 minutes of it!
Some might say that taking on a 3 hour endurance race was too much for my old ass, and my only graceful way out was to select first while flat out in second at 10Krpm. Four times.
i think i just hadn’t got used to the new gear change setup
Took engine apart in the paddock, always wanted prove it was a 86cc in front of the other racers
Lovely destruction.
From last to sixth in the first lap, then i led for six laps before blowing up. proved i’m the best, just didn’t have to go the whole way to prove it.
Fastest laptime of the honda engines. Funkie Junkies have a YX of unknown CC with some honda cases slapped on the outside. Chicken Chasers were more open about it they have a YX120.
A Fish Called Honda (thats me!) is/was running an 86cc, next was Team Cider with a 107cc, then Classic bikes with their 114cc. All honda based, i’m the best
I’m stole the trophy because i’m also the sneakiest.
ok when i say stole i really mean traded my DNF prize of a Rolo easter egg. nice.
Nifty fifty 2019 went ahead without me, sick wife meant no fun for me, however it was hilarious hearing all about how the pro racers did in my absence.
dead last, crashed twice and jumped the start. first ever restart in nifty fifty history afaik.
also they stopped racing because it would not go forward. not sure how they could not see that the front sprocket fell off…
Anyway, my dads new engine worked well so the old stock 70 is now surplus, mine now!
Poor thing.
88cc head, never got it running right for the race and took it all out for 86cc the day before the race.
c70 head, same head e22 as on my 90, except for all the missing chunks, and the sealing surface. this is after i abused the fuck out of it with a plank of wood and some sandpaper.
note the exhaust valve, just a bit burned!
easy repairs first for the race bike, throttle housing snapped, looking closely it was cracked a long time ago and only let go now.
also found another old crack, load of epoxy glue lathered on and it’ll be grand
Next thing is the gear change, what i had worked great for the manual 4 speed, but the auto clutch in the three speed is quite banjaxxed, and needs a bit of force to change gear.
so the lever could be a little longer, easily done. but the rod also needed to be longer, not having the right tools i done a bang up good job with stuff i found on the floor, quite literally.
Slicks for our not very good pitbike we intend to race against some quite good pitbikes.. more on that later.
rg125 on hold
I like cooking alot, but my knifes selection left alot to be desired, so i made a better one!
polished up nicely with some 1200 grit, already feel the urge to get a 2000 whetstone from amazon.
Rg125 raditor, considering my options, do really want an upgrade.
Everything stops when the music isn’t right, poked the wires and we were back on track.
Beat that straight
this bit needed more finesse, less hammer
a selection of tidied painted and bought bits
Helper number one fitted it all up!
And now the rg is on hold because this cub90 is now in the shed, gotta run it in on the new years day run and lots of other bits need completing before race day.
the netbook, the 88cc and the rg125
So first a little update on the netbook situation, bought a dell 2120, super cheapo, didn’t realize they came in single core models..
upgrade time!
Whole motherboard upgrade,
*eyes wwan port* pci-e ssd?
failing purple msi wind gave up its ram and ssd to my new chunk top.
Anyways back to the fun stuff, clutch carb, and rev counter installed.
They don’t work, but they are installed..
Check out the rubbing from the carbon fiber pipe on the shock 🙂
new old pipe is the best pipe ever.
springs installed to keep choke from closing accidentally, and the throttle from accidentally staying open 😀
Ford bits installed!
These will be where i install the rear sets, next week probably, no mig wire!
Pump and switches for runner 180 water pump mod.
Onto the Rg125, gs500 37mm forks fitted up quite nicely,they are a ton lighter and 0.59kg/mm springs seem to suit it
lock stops, steering lock, everything perfect.
Top yoke is ugly, but what are you gonna do?
Whole thing is sitting a bit high, we’ll fix that.
gs500 wheel is drop in replacement, if you needed to keep the stock gsxr forks.
Disc is a 320mm vs 310 and the speedo drive is a smaller outer diameter
Replaced the lower bearings with ebay specials, no rubber seal, unlikely to do so many miles i’ll need that. Dogbones need extending to lower the back about 3cm according to my calculations
extended 6mm, or at least i planned to, actually got 5mm, best i could do with a angle grinder and a stick welder.
Dropped fork 50mm, threw on the clipons i bought, i bought 38mm clipons cause i’m an idiot, rushed to buy them, nothing an angle grinder and some filing couldn’t fix. I like the radial master cylinder.
Onto some plastics mock up.
Fitting the under tray and some of the electrical loom
Probably gonna have to tidy that, quite heavy too!
Big gaps, need to move tail piece forward 30mm
2T oil tank i don’t think will fit under the plastics, thinking of making a tank and putting where the batter lived.
Moved forward here,
Much tidier, gotta weld it up next time i’m out there.
And also my cbr was sick!, ran rough as feck, very close to happily dumping it in the spares pile (already on DoneDeal looking at other bikes) but then we found the blanking plug for number three vacuum port, fallen off an sitting in the vee behind the cylinders… pop’d it back on and the cbr’s butt was saved again for another day.
Rg125f boring paint
Skyteam Ace 125, suspension upgraded via some spacers, 16mm worth.
Easy to get forks out
While it was out, banged on the disc a few times to straighten it, poor thing is a little over worked.
On to the Rg125F, stripped rear shock, we have a
295mm length (c to c), 30mm fork at bottom, 30mm eye on top. m10 bolts.
160mm coil length on shock, 9.9mm diameter metal, 5.5coil 2 dead coils. 70mm outer diameter
175mm length off shock, one end is little smaller, last coil so not calculating that.
closed and ground spring
using an online calculator thats a 8.0kg/mm spring, 2010-13 s1000r shock with lots of cutting of frame is a cheap upgrade, spring is only 8.2 to 8.4, so a little stiffer, but not too much. have to get my hand on one.
Vj21 rear seat (left) vs Rg125F seat, rg125f is fat fuck.
so i had a vj21 in shed, do the plastics fit?
No, but i’m not gonna let that stop me from fitting some, such slimness!
Paint rear swingarm
More painting
Playing with fitment,

Repairs
Stick welding ftw?
rg125f engine destruction
Tis grand! bit of diesel and off we go!
lol nein. got other projects that need attention first, then we’ll spend a bunch and fix that engine right up. and tune it of course.
so the really really boring part
yep cleaning and sanding and filling and organizing my spanners. I’M NOT OLD OK!? just had an off day, it was raining.
I did mount the old rg tank at least, like a trophy. 🙂
slinging a SBC like my 8 core odroid into it will be easy, but it’ll need slinky heavy metal hoses to house various cables, gotta have the look right.
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!
start ya bastard
Yzf runs! manually fed the carbs with a funnel and attached a battery directly to the starter motor, will attempt to put it together next day i have off.
bike insurance is up, so i’m tempted to retire the cbr and make the yzf my main road bike. many break downs will occur.
Always wanted to take a shot of a stock corsa next to mine. amazing how you see the same colour car as your own all the time, despite thinking to your mind no one in their right mind would buy a car this colour. Finally tracked this bugger down, and i had my camera on me this time.
Tall isn’t it? if i could only find a three door in this shade dropped to the floor..
racing fiftys and restoring 7fiftys
So nifty fifty 2015 race report, it’s not good people, first i got a camping stove so that i wouldn’t smoke out brahams van. then brahams van died, so i stayed in a B&B with stephen.
morning of the race..
race was a complete fail. the transponder was flaky, the tyres had 30psi in them from the new years day run, i fell off, braham fell off, i was 7 seconds off, dropped tyre pressure to 24psi instead of 20 thinking the tyre was hot, not quite enough but better, at the end of the day i took the last 15 minutes of the race and got down to a 1.32, still two seconds off but lessons learned for next year.
Next important thing is the fix up the yzf750, gotta do some trackdays, yzf is perfect.
Decided to change the front wheel, i knew it was cracked and had been welded very well, but it leaked and anywho i had a better wheel. Also reason to change from badly painted orange wheel to yellow, mismatched lurid wheels are so 90’s right?
no contest in the end there was only one yellow at halfords and i can’t be arsed to go any further, on with the white primer and soon on with the fiat bloom yellow.
More bits lost, fucking clueless as to where everything is. they have to be in a bucket somewhere!
this upper bar is supposed to be horizontal as far as i can tell from yamaha brochures. i’ll weld it up when it’s back on its wheels and the body work is going on
Future bajacorsa tube bumper?
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?”
