Tales from the Emporium

[tri boy]

Big for an air/oil cooled big single? The water-cooled 640 LC4 spec is 0.10-0.15mm.

Yer Triumph is 0.15-0.20mm on the exhausts!

As I say, i've been off the bikes for about 15yrs(commercial w/shops), and when i was in it, most of my work was on four stroke multi's, and alot of performance work. (GS,GSX,Z's, CB's etc) methanol, avgas stuff.
Most big Suzi's ran close tolerances, (about 0.002") to get them singing.
And speedway/drag engines? Just enough to let the oil under the followers.

Chook chasers and the such weren't my gig, so forgive me if I'm out of touch.
Maybe the Volty could use some serious "Bombing".
PS, only had one engine fail out of many. Our Speedway sidecar broke a crank
clean in the centre last meeting of the 88 season. Mind you, that was a serious firebreather.

You're forgiven. I understand peformance stuff would prolly be tighter, more attention to detail and to get the valves open further.

Today has been "tidy the dash day".
Found some LED's at DSE that already have the ballast resistors and 10cm wires attached to hook straight up to 12V.
They come in 5 packs for about $5

A piece of foam later and the proto-dash is born.

It'll be made in a peice of hard plastic sometime but I'll see how it works first.

It's got a blue neutral light in the middle, a pair of white ones either side for high beam and aux light and a pair of red's at the ends for the blinkers.

I cut the rubber mounting block for the old lights off.

[GaZBur]

That does look pretty fancy and probably heaps more visable than the standard lights. I always wondered how people could be so damn silly as to leave their indicators on as there is a flasher. But today I noticed the indicator flasher is not visable because when you have your head up the chin of the helmet obscures it. Wonder how long I had them going for??
The patented NordieWonderDash would fix that!

[NordieBoy]

Yep
I think the old ones are 3w or so and the LED's are 0.06w but considerably brighter.

Next, lighting wise is LED blinkers and numberplate light.

[NordieBoy]

Right...
Just made up the final(ish) version of the dash light mount.

It weighs about .00005g so should improve the hp/kg ratio by about 15%.

looks good mate,nice job

[deanohit]

Blingin maaaan!

Thats a real tidy looking job you did the Nordie.

[Mole_C]

Hmm synthetic oil or normal oil for the DR650 with 8000kms? Just brought 4L of Motul 3100 (normal) + filter and wondering if i should go back and change it for 5100 (part synth) or just bung it in?

[NordieBoy]

I'm using Total Racing 4T, 5L for $38.
2 complete changes out of one container

Some have noticed some more sounds and/or clutch issues with fully synth but technically you should be fine with fully synth.

New tyre time today.
The first time I've ever put new front and rear tyres on at the same time

Officially they're Shinko SR244's but unofficially the front has identical writing except for the words "Golden Boy" instead of "Shinko"

How long did the last shinko rear last you?

Cheers R

[NordieBoy]

How long did the last shinko rear last you?

7000km with at least another couple of thou in it (all at 20-22psi) but I didn't want to risk that cut in the sidewall (that I got the day after it went on the bike) on the Dusty and today was the last day CycleTreads was open 'till the 8th.
It's now my emergency tyre.

The front IRC GP21 did just over 16000km (the last 7000 at 20-22psi) and I'll be getting another but they're not due 'till mid Feb.
It's not going to be an emergency tyre as it was pretty shot a couple of thou ago.

[NordieBoy]

Went through the Maungatapu today.
20psi front and rear.
The back tyre was fine but the partially worn one was better (a bit much flexing in the knobs?).
The front didn't do anything wrong but didn't inspire confidence on the gravel.
I'll try 18psi next time and it may also have been the type of gravel and may just need getting used to.

[NordieBoy]

Tried 18psi front and rear, felt a little better in the front and no difference in the rear.

I think I'll go with 18 front, 20 rear.
As it gets hotter it'll go up a couple of psi but one of the rockiest sections is at the start in the cold.
