88cc engine swap

Cleaned new engine, a bit, didn’t actually put any effort in.

86cc racer looking resplendent in battle scar red and rust.

last race at watergrasshill saw this tab for the leg shield break off, wouldn’t be a problem normally except i can’t find the tab. Have to make another.

built this in 2014, it’s done well to be fair, sold now to my dads team who’ll slap a smaller class restricted carb on it and attempt to win the stock class.

Engine vibes? i knew the engine was very vibey, my first though was loose engine bolts, now i know it was a loose engine bolt!

Tillostson looks purposeful.

Plate that some of the previous electronics were mounted on, it fell off a year or two ago and was just rattling around under the tank, finally gone. Can still see the melted plastic from this bikes previous life as a bonfire.

Stihl 090 90° elbow on the way, gotta flow it a bit and attache a filter. also the throttle cable, i’m just ignoring that huge ass pain for now..

More Runner 180 water pump woes, not sure if i want to leave the impeller behind when i switch to electric pump.

Splitting cases isn’t that hard i suppose.

slap that 88cc together

Went with boring paint in the end, figured everything else is a bit mad, so tone it down.

Needs second coat and lacquer asap, but didn’t turn out that bad considering how much i hate paint prep

Order a very cheap radial master cylinder, wasn’t really surprised when i saw this shitty casting, at least only on the clamp part, the body seems ok. i hope.

VJ21 race fairings, strangely modded road ones, was expecting much more straight forward molds, ejit store sent me a smoked screen after i asked for a plain one. sigh. still rg125 ought to look much slimmer with these clothes on.

Race 88cc, in one piece now, gy6 88cc piston installed, used a 107cc head, of the two i had the 107 had better castings and i have a lumpy long cam for it, head with the smaller chamber used a shorter cam so i gave up on that.

very direct tillotson carb, should work great!

That is of course if i can get the valves to seat.

after some lapping there are still not so good, but alright for testing purposes!

new piston is much bigger then the stock 50(right), and has a lot more compression then a stock 107 (left)

perfect deck height.

107 head on right, you can make out the combustion chamber size difference, plus the extra cooling fins.

some Runner 180 info, gotta build up an electric pump kit, toyota prius inverter pumps are perfect, but finding a switch to turn it on is not cheap, so i’ll probably settle for a switch.

uprate the cbr6 brakes, eventaully.

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?

I should do these updates more often

Well lets be having them updates!

Rg125f first, box of clean bits, the box of dirty bits is quite large..

painted the top yoke a few times. i should not be allowed paint.

filled the dents in the spare tank i got, it’s still low, but IDGAF

Hammerite paint job, laid it on a bit thick and forgot to use a roller so it’s terrible. gotta flat it back and do it better. not properly but better.

Forgot about this, happened a long time back, belted it round with a large hammer, took a photo but i dropped the camera and knocked the battery out as it was writing it. promise i’ll get one next time.

Head, badly in need of modernization, if there is enough meat we can do an angled squish and a bathtub chamber. if not i’ll buy an insert, make a steel cage and 3d print to hold the water in.

 

 

Next!

Lifan monster 120, advertised as a 125 (insert joke about penis size)

we have a 27mm inlet valve on this so an appropriate carb is needed. mikuni DBS28, cheaper to buy a bank of four then one.

ah didn’t need that hi comp piston

is that a rice grain in my engine?

Beautiful

On to the Wifeys Dax.

engine was ripped out for new race engine.

what cruel bastards restrict a 50cc four stroke? this is the second washer we found…

Frame repair.

new chain and sprockers, bit oh cleaning of the wheel too.

de badged! and a new engine, 86cc single speed out of a childs quad.

a spin reveals that a straight pipe 8000+rpm doing 50kmh is not all that much fun.

Stickys!

also much taller, should help with gearing.

that exhaust pipe is dangerous to small birds and single pane windows.

need a pipe, stock is fine, but it have a cat in it and is too short for the new taller engine. chop! grind booger welds, insert rusty crap pipe.

looked well. no idea how it sounds, we still have to fix the loom, it eats cdi boxes, probably the tank rubbed a short into the loom.

Misc:

New race head, actually has a 52mm combustion chamber. huge head off a vintage thingy for scale.

got the arcade cabinet looking tidy, ditched the fancy router and did it manually.

more t-moulding

stickys for my dads skyteam ace 125, stock is so bad.

when you go on hols, take a ferry, and discover an arcade where your mate Stephen Casey has been.

Got a vice! had to clean the paint off the runners under neath before it slid smoothly.

rebuilt my numbpad for the acade, lots of trimming this bit down to get the case to close properly, then glued to the face of the cabinet, works great! can’t decide what buttons do what in the config yet..

nifty fifty 2018

New years day run 2018:

Like the colours, if it makes other people go what?! i’m down for it.

Want to race this guy, but he said the rain plays hell with the traction so he went home 🙁

68 years old and getting used, top class.

Race c90 back after test run, taller rear tire is a tiny bit more unstable, but grip was fantastic.

Oh look, my fecking cbr6 ain’t charging again.

also found that the plugs are getting a bit fouled from short runs to work, gotta change those, so i bought this to help:

knew that spare frame would come in handy!

getting nearer race day! lightening program is making progress..

Fitted temp gauge because i was hoping i had blown something, but no it’s fine damn it.

attempting to get someone elses race transponder charged

Final though before nifty fifty 2018?

Race Day!

Well first thing that went wrong was a burst water main, Thomas Maxwell could not make it, but he had a friend that could take his place so. ok then. Paul has ktm dirt bike is half my age and never been at a tarmac race… this was the night before the race as i sat in the car driving up to dublin..

Three people on our team myself colin and paul, we can still split up the race between us, have seen my bike do 1h30m of racing before so decided i’d go out for an hour and thirty minutes, you’re never sure how long the race will be and paul didn’t have any experience.

went out for 1h27m, ran out of petrol but still made it to the pits with out stopping, loads of bouncing about trying to slosh fuel into carb. Had huge battle with team manly, some fella name cody nally? never heard of him, he kept up ok. i was third in class as i pitted, absolutely buggered,  knees and shoulders wouldn’t work right for days after, footpegs so far forward made hopping about alot of physical work. the straight bars wrecked my right wrist as well.

ABR moto/Driving miss daisy/Funky Junkys had alot more power, past me going at least 5k quicker, ABR/BMD are both english teams so they had 107cc engines i’m sure. in plop enduro racing you have to keep the 19mm carb, no such restrictions over here so they were bored passing everyone.
Colin went backwards unfortunately, new guy paul rock kept us in place and was steadily improving when the flag dropped.

6th in class, 9th overall 1:26.160 77.298kmh
teds team finished one lap behind us! on a stock 70!
dry race, tyres fantastic, i would have been well into the 1.25 if i had not changed the gearing combo down to 36 tooth rear and not taken into account the taller rear tyre also stretching the gearing.

ABR moto Driving miss daisy / Funky Junkys had alot more power, but they couldn’t take a corner to save there lives, next year will be the year of the my 89.3cc BBK! Seriously next year is Win or i’m bringing a two stroke to nifty fifty 2020

 

 

Best 86cc bike out there, A Fish Called Honda

and one week later we were all balls deep in snow.

Back to normal,Fucking cbr.

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.

Other things that happened

Oh whats this for?

🙂

But never mind that, time for a spin!

Tasty noise

Bought a new bike! only new bike ever, yet to drive it, stock is too slow!

Race bike got it’s tyres, it started too. Ready To Race.

Fixed my shaver charger, “fixed”

Flat battery,

Fecked rectifier

Soldered all in again top job.

15 years plus that stone has been in my knee, so nice to have it gone.

naughty

Dog has a help out spot, but only when the weather is nice.

Runner is dead, wibbly handling isn’t as fun when you have no one to race!

Engine will live again in a decent go kart frame

Got that front end on!

feck it these clocks weight tons! steering loads lighter, that may have to do with different trail figures and the lighter wheel

Very cracked

shed upgrade!

Rg125f Disassemble

Literally dug this out on my hols, gotta get a better hobby.

Made it to the trailer, tyres keep air in them!

Engine so not healthy

Tank, yeah that was fucked ten years ago when i put it in that ditch.

Made it to my house!

On the plus side, the exhaust does not have any holes it shouldn’t have!

Piston, well it’s still there..

Total restoration,

horrible isn’t it? not the spider he’s cool.

CDI seems to be one of the good ones. 32900-19d90, well it was quick enough when i did run.

Do i need half this shit back here?

I don’t need all this shit in the airbox

🙁 revg250 34mm carb is dead

So dead.

alrite boss

that was cracked years ago too, lost the head bolt and the vibes cracked it.

this tank is magnificent

Gonna install a PC in to it, of course.

Lighter rear, more may come of, gotta save weight this bitch weight 125KG dry!

I broke no bolts getting to this part, no Suzuki bolts anyway.

This is the only damage i can find after the crash that put this bike into the hedge for ten years, bike is over built.

And we’re stuck, swingarm axle needs heat and a much bigger hammer to move it,

rescued the petrol cap!

Spare part hunt turned up 5 cylinders, at least two of them are 22d0 vj22 cylinders, those should be the best for power.

Many carbs, i think two are 32mm carbs and the rest 34mm, didn’t have time to measure.

GSX600F front wheel, took it off for another project, but might do for this.

GSX600F disc’s, not to my taste but probably the right diameter .

GSX600F calipers also should fit, may fit them because they are smaller/lighter

 

SO many ideas to tune the engine, think i can get a solid 30bhp at the rear wheel, most of the ideas revolve around better head and squish, better cooling the piston so i can run more advance.

will post what i do here, when i decide what i want to do!

axiam mega city, more half assed

So thats the service, battery, huge and 0.0 volts.

The main traction battery, fucking heavy.

Find the dead battery!

Dropped a tool into the depths of the motor bay, so had to take the soggy under tray off. found a nice diff/gearbox, it’s clockablity is making me want to put a bike motor in.

also the bloody expensive broken leccys bit, they want me to put a bike motor in too.

this mofo

dead service battery replaced by a semi alive traction battery, for now.

new config, still 48volts

so dead, so heavy.

still have to replace the ESC, want to mount it inside to avoid getting it wet.

TerriCab #4

Very long time no update, so now there are lots of updates, because i never stop taking photos of things with my crap phone:

kept working on the old pc speaker amp,

replaced many old crumbly connections.

added a soundcard, motherboard gave out about that, rubbish toshiba.

gave up and bought this! way better, no pops crackles or other ear shredding sounds.

While i was buying things, it’s fun, but does not save your score.

Back to to wood work:

Shed got a light!

TerriCab got more reliable WiFi!

Card didn’t fit so great so a standoff needed the chop.

Painted the monitor bezel

More to come,
