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?
more bajaj brakes
Well, the old holding down the lever didn’t work so i cracked on with the nipples, which didn’t work either (5/16 size for those interested) further inspection revealed the sexy aluminium drums (well when there clean..) and the fact the rear wheels can be reversed easy like if i need it to be much wider.
So i pointed the blame at the slave cylinders, and i was right! the rubber sleeves had disintegrated and water was left in, created rust and muck just where you don’t need it, clean them up and no joy, bigger 14mm master cylinder bunged on, will weld that up next week.
Tzr250 3ma oil pumps, the short one is the earlier correct for mine one and the long one is in suspect condition as well, bum hats.
I’ve been trying to talk my self out of doing this for a few months now, but the little voice in the back of my head got a tiny foot hold and told me it was okay to make up a photochop, the idea is now fully formed and raging about the place now..
Check the foot peg placement, totally doable, the air box will fit under the seat, a new subframe and tank will have to be made up to go under the seat, a wider seat will have to be made (about 2″) and the bars will need massive risers, i’ll be on tippy toes where ever i stop.
bajaj brakes
Got brake lines in pretty quickly.
There a bit all over the place, should have spent a bit more time measuring the lengths.
Still there all in and not leaking (yet)
The bleed nipples are imperial, so i’m not risking rounding them off by using them thus i needed to raise the front like so and put a weight on the pedal, let all the air travel up in its own good time to the reservoir.
If it all goes well, i need to fix a brake light switch and brace the master cylinder mount, then the electrics.
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?”
more trikes, more bajaj
Got a pic of the quad or whats left of it, gonna fit that sexy monster swingarm to this to make a reverse trike, don’t like reverse trikes but it’s all cheap fun.
Needs lowering, also we found that the lt50 out back has the same 3/90 pcd as the chinese quad axle, we’re borrowing those wheel anywho!
Saw some fricking sweet atv wheels which NEED to be fitted to the bajaj, but thats for some other day, for now i just robbed an xt350 switch gear for the wiring loom, whipped the body off for more repairs then welded in extra steel to support the brake pedal.
Not much done really, did spend the day convincing ted we need those two honda 125 engines for our new trikes and that he had to buy them, and once he has them sure it’ll cost nothing to throw them together, they’d make excellent winter hacks!
busa and mad trike ideas
Did i mention the quad we got last week? going to fit the rear end to the monster pitbike out back and make a trike, probably will lengthen the swingarm then we gotta find wheel/tyres/sprockets. I’m sure we have a big engine around some where to go into it.
Back to the busa, got top fairing on. still think the clock cage is wrong.
before putting on the side faring we inspected the small leak from the starter, the gasket seemed fine, but the oil was coming from the bottom bolt, added a soft washer and threw it back together.
Only the right side fairing on, i’m short some bolts since it don’t have all the original pieces. the pics don’t do the blue justice.
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.
bajaj head light
Bungie cord helping out here with test mounting of gsxf600 head light
Why a gsxf600 light? cause it was closest to hand.
Top is handily mounted on the tab for the plastic horn cover, tabs on the bottom were from the bits i cut off and re-welded back onto the arms. Job done.
Also sorted which wire stopped the engine, only after five minutes of wondering why the feck nothing worked until it dawned on me the rear harness was not attached to the front harness at all, doh!
Runner 180 Kart airbox
Well heres how it looked the other day.
Ended up putting back on the front mudguard , doesn’t suit the massive rear tail and i need that tail since i don’t want a wet arse.
More bits left over.
And this is where i left it to go to the..
..Munster 100! i sponsored a bail for that you know! this suzuki 250 below won the classic.
This suzook was some where down the field.
What the feck is a tsr250?
NomNom
Anyways after the neighbour ciaran won the 650 race (passed him once on a track day) i got back to finishing the runner.
First up was to remove the superglue from the inlet, it was already cracked, but only on the outside. cheapy poo.
Then while i had some epoxy out i fixed up sarges old bandit cover, which will be handy for the gsxf track bike.
My modded kickstart got modded again back to standard so it wouldn’t hit the new airbox, with all the pies cut out of it it’s a bit shorter now, and i have to stand behind it to kick it properly again but at least i have a choke now.
The articule, very light, but beginning to think it really needs a big spring or rubber band to hold the airbox in place rather then the single bolt at the rear, very vibey these things so i’m not gonna be very surprised when that little tab at the back breaks.
How does it go? bloody well, needed to raise the needle for more fuel and what goes with more fuel? more air! the engine is getting more air then when it was just a filter, job done.
well i still have to run it in a bit more and then do proper flat out testing and jetting before it’s really job done. also i’ve scored a pm tuning head with slighty dodgey spark plug threads and the handling is still rubbish. so really not job done i suppose.
cbr6 servicing
Going to the munster 100 on sunday, so though i’d better get the cbr ready.
Lost all my keys the other day so had to chop off the disc lock, that was fun…
filter didn’t wanna come off, the houseing did but the threaded lower part didn’t, got it off in the end with a punch and hammer, champion 306 filter, now it’s got the old faithful HF303.
at 44630, it’s a bit past that last service, but despite the crack (small stone hit it) the filter got almost straight away it still had almost 4 litres of oil inside.
