Spooky. There's still a shed in Belgrove...
NordieBro may or may not be going to the Burt. The builder of "The Mongrel" may or may not have it together in time.
He's not interested in getting it going on petrol as meths should be enough for anyone.
198? YZ250 with a TZ350 engine putting out >80hp at the wheel...
Pics please or it doesn't exist.
Had some pics from my phone but can't find them now. Also contained a video of a Kwakka 1400 speedway sidechair being dyno'd...
They are probably cuddling up to Peter Un'Dunne's emails
or on a tax payer tramp thru the bush at Milford Sound with Nick Smiff...
I heard that going from outside the building - very scary sounding.
Don't worry about the mongrel. it won't last for more than one straight as the mech will only have just put it together 3am that morning after having 3 years to do it
Good to see the scrawny bugger back tho
Dunno what Bruce was thinking, letting Lester loose on gearboxes...
He sings along to songs on the radio too. Really, really badly...
You know the sound a car with dodgy power steering makes? They have to pay Lester royalties...
So here we all are.
A balanced crank [ 80% ] looking at it's new home
For what we are about to receive
It's coming together
For Motu, yeah the new timing gears are heavier, $40 for the gears, 2 doz beers for the drilling, pretty . I chose 7 holes so I did not have weak points on opposite sides of each gear we will see how it works out.
We struck a wee hitch, the tappets don't quite fit the tappet blocks , bugger all in it, but I will take them to the machinist. I could lap them in but that just accelerates wear on the tappets
Today was a wash out. Brought a TY175 for the Photog & took it out today.
Photog & I sat on a log while SWMBO went round & round telling us how much fun it was. :ddog
We now need 2 more trials bikes
Looks very cool. I'm gonna drill some parts out on my engine. Dunno what but I'll find something.
When is it going to be doing laps?
oooh looks good, how do you find the treadplate aluminium on your benchtop?
Pads , you ride a bavarian tractor. the world is your oyster..
Bit of luck early August
OK . not ideal, gets a hiding, we use what we have, 'translated' , cost me nothing.
Good Work, are those red book Triumph Manuals..... I can see the adjustable spanner ...where is the hammer?
Ready for August?
forget all this boring geriatric triumph crap
where are the photos of the TY?
actually I really like the geriatric triumph crap
I thought the timing end of the crank was supposed to be mushroomed over ? ...they all were in the '70's. That looks like a heavy crank; I think '61 was the lightest crank, and then they got heavier again. I used to be a light flywheel type, then I liked heavy, now I'm back to light...although that might just be an Airhead thing.
What are the books - engineering textbooks you'll never use again ? Or well read poetry?
I went to a twinshock trial yesterday...just for a look, get back some enthusiasm by saying the sections looked too easy. A TLR250 was there, and an even rarer RTL250, I need to get the TLR200 back in the mix. There was one TY175 - what a nice little machine they are. Slippery conditions, but he was having trouble keeping the front end down, something they tend to do.
Cool little bike , great fun
The books are ' Arthur Mee's Childrens Encyclopedia ' ,[ google is your friend ]
Been kicking around the garage for years just don't have the heart to throw them out, sacrilege I guess to use them like that , they were handy.
Dry build to check the piston / valve clearance today , more pics to come.
Thanks - looks like someone rebuilt it to compete in twin shock trials?
Tidy looking bike
so no drinking in the garage today
Getting off topic with bikes that run
If you wanna take it up to the Sandpit, you can borrow my KDX200
One step forward , one step back
Set up the barrel
Removed the outer valve springs
Fitted the head bolts
Then the head
Rocker boxes on & degree wheel set to check piston to valve clearances
Checked at TDC , - 10 & + 10 degrees all good ,80 to 120 thou which is what I was told to get, You set the tappets to running clearance then wind them in till till the valve hits the piston, one turn is 40 thou, high tech marker for the degree wheel but it works
Stripped it all back down to fit the rings & start on the final build.
Oil rings fit sweet as
2 x top rings will not fit . Looks like the rings are approx 0.2 mm too thick to fit the piston ring grooves.
Yet another email to Mr MAP
Will go to the local engine reco man who does a fair bit of performance work & Johnson Rings tomorrow to see if I machine the pistons or take my 9" grinder to the rings
If I did not laugh I'd throw something.
In frustration I went & put down my first batch of home brew, this garage is no longer dry. :slurp:
