Tales from the Emporium

I've been playing in Google Earth with tracks and trails and having a bit of fun.

Save THIS and open in Google Earth.

So my bike has now done 25000km and 455hours.
My 14t front sprocket lasted 6000km before it was poked (I'll find out what brand it was).
The previous one went about 20000km to a more poked level of pokedness.

I've been riding on a 15/43 combination since the Dusty and don't like it much.
Put a new JT 14t on the front just now.

The 6000km life sprocket was a PBR.

Having a play with a modified 150 DynoJet mainjet now.
155 is too rich and 150 too lean so 152 or so should be good.
Need to play with needle positions now as it seems ok wide open but stumbles off idle slightly.

photo of what you consider poked?
You show me yours, I'll show you my JT 15 tooth with 10 000km on it.

I have the 15/43 combo and is my new favourite. The 14/43 just didn't work for me.
Every Mangatapu trip and the DB have been all on 15/43 for me. Did the Brass on 14/43 and didn't find it helpfull, although on the Mt Olympus trip I can be heard saying I'd like another gear lower at times, like a 13/44 might start to produce, think that's what Far queue uses in trail mode. Hate to ride that on the highway.

This is the really poked one. I'll have to dig out the other as it's almost pristine compared

I found on the 15/43 I was using the grunt and spinning up the rear up steep sections whereas with the 14t I'm able to go slower and cruise up without breaking traction so much (unless I want to).

Just be thankfull you wern't trying to carry a Transalp up there, and on road orientated tyres :

My hooks have nothing on yours Nordie...

[NordieBoy]

You nicked my PBR!
Mine isn't as worn but I can see in less than 1000km it'd be at that level.
But as I'm averaging 2000km per month 1000km isn't long.

[NordieBoy]

The 152(ish) main jet and clip 4th from top ran ok but was very hesitant/boggy off idle.
Changed to 3rd from top and it's better off idle but has an uneven idle now.

I compared my JT front sprocket with TA's today. We both put them on around late Oct/early Nov last year, TA has done 10300ish (as above) and I have done 4000ish. Mine is more worn than his by 25-50% I recon it is cause I didn't turn the scotty up enough when off road. Going to give it death i.e. heaps of oil from now on. Might even try 90w gear oil and just pump the stuff through when off road - will make a mess but what the hell. Going to do this in the hope that oil buggers off more i.e. doesnt stick so much and therefore takes the dust/dirt with it.

Load it up with ATF.

Different chains or wear levels thereof?

Sounds like maybe you want to go for a thinner oil, not thicker (although 90W gear oil is about the same as 30W motor oil). Saw a recipe for scottoil being 20W engine oil diluted 3:1 with kerosene. More thin oil, flushing off the chain carrying the dirt with it? It's the constant flushing off of the grit that gives the scottie the advantage over an irregular thick coat of sticky spray lube.

Hmmmm???

Exactly the same chains EK MVXZ. Thinner or less stick to be more precise is the oil I was aiming for. The scott oil seems a bit like air filter oil to me - not very viscous but very sticky. I'm not sure that the scotty oil would be engine oil diluted - it is rather more sticky than that. I want something like a regular car oil that is not sticky and will just keep buggering off. I have plenty of 90w diff oil from 4wd days hence why going to give that a spin.

Also while talking to TA yesterday I think I'm going to stick with the D606 rear for one more round just to give it a fair shot at proving itself. Every time I've put one on I've taken it off again fairly quickly afterwards (as wanted to kill other tyres first etc) or it was the DB1k i.e. it got an absolute hammering. So to date I've not given it a fair run, hence will do this next round.

Hmmmm???

I think it was on Visordown that a ScottOiler engineer piped up with the tidbit that they use a modified auto trans fluid.

[NordieBoy]

I lowered the needle to 2rd from top with the 152ish main jet today to try leaning it off. It needs the mixture screw wound right in to run properly.

It didn't run this rich with the 155 main, the needle 2nd from top and about 2.5 turns out on the mix screw.

My 152ish is definitly smaller than the 155.
I think I'll have to get another 150 (Can't find mine - it's not in my jets box).
