papa Thailand now.

Had a swell summer riding the 

TY350s around the high country tracks.

The 1985 was down for over a month with a rear wheel rebuild.

Woody's Wheel Works in Denver

It has those z-spokes.

The wheel hub became sloppy and at first papa 

thought it was bearings but no.

When tightening 2nd spoke...

PING !!

Thank Buddha for the '86 for back-up.

papa loves those little things.

 

Hauled Climber & Cota out to KhawMaeKaoew today.

Maybe get them started 2mor.

He has 4 now.

I think he likes motocross.

In 1967 I was 15 and the Tiger Cub was my big dream..and what I was saving up my pennies for, until my mum came out against bikes. I wonder if I would still be alive had that dream come true. That is a nice example.

[papa al]

The Climber started right up on a few kicks.

 

Riding conditions at KMK have changed these past 5 months.

Rains have grown the foliage of course

and have gullied some sections pretty bad.

Crossing an innocuous looking 'puddle'.

papa got stuck in a mud hole to the hubs.

[This sport is so fun.! ]

One trail which cuts above the lake inlet is eroded down 

5 meters or more.

Entropy.

Long live the Honda SL 100...

[Damrongsak]

I had a Honda SL 125 back around 1972/73, my second year in college.  Reliable.  I used to do some short, steep hill climbs on that.  Learned the art of turning around 2/3 of the way up and riding back down.  Hit the base of the hill running about 10,000 rpm and turn sideways when it ran out of steam. Lay it over a bit and let the front wheel slip down until I was pointed back down.

papa went riding the Kaw Thursday.

Pretty nice now cooler and dryer.

Fallen trees have been cut out.

The Climber is running good.

 

My little buddy Gun has been racing motocross.

He [8-y/o] took 2nd in the 50cc /12-y/o class at recent championship.

//// on his KMT 2T.

He has 4 dirt-bikes now.

He be racing this weekend Chantaburi.

Reporting from KMK.

Trails are in good shape.

Haven't been up in the trails on the north side.

...dreaded Monkey Mountain.

 

...guess they are not having the Enduro event as they did two previous years.

"No money"

Which prolly means no sponsors.

 

 

The local guy is more focused on his son's MX

than Enduro now.

 

This is an excellent trail system.

Anybody want to go riding there,

PM papa

RE Aprillia Climber w/ Yamaha RX-Z 2T engine.

On the 17th reported work on the front fork seals, bearings, 

on other thread.

Saturday went to ride but noticed some gas leaking near fuel cock.

Took to shop & also asked him to check rear hydraulic brake.

He fixed the line, but was having trouble getting the brake to work.

He removed the whole system and was trying to figure it.

Late, so papa went home and on returning Monday

found he had to replace the master cylinder.

B1020 covered the costs.

So out for a ride today, dumped her ascending F... Me mountain.

Bike & papa, rubber side up.

papa okay but smashed the oil sump sight-gauge on R case.

Damn.

Pushed her the 2-3 km back to bike barn.

Rode ceeber back to Patts & checked at my fav shop

but they said no hab part; no hab book.

They suggested checking the Yamaha shops

on Sukhumvit who, sadly did not give AF.

Found the Yamaha part number online, &

with that my fav shop said they could order.

2 weeks.

Guess papa will be riding Cota for a fortnight.

How you gettin' on with the Cota Papa?

I would have thought the Cota would be a better bike in every aspect compared to the Yamilia?

Thoughts?

[papa al]

Cota starts and runs fine.

It is almost too powerful.

Getting used to it tho.

Use 3rd & 4th gears more.

 

Climber uses 1st mostly, in ruff stuff.

A lower low would be better on the steep uphills.

Way better fuel economy/range.

 

TY350 funnest among the three,

fer shur.

SongKran will be 3rd anniversary of 

acquiring the Climber. & 

this thread.

So papa has a couple seasons + riding the 

stand-up thang.

Has been really fun and good exercise.

Best of all, no injury,

despite numerous tumbles.

Cheap armour does the trick.

 

The  $110 ONeal MX boots.

are on their last rides.

Have thrice mended them with copious hot-glue application/injection

to fill divots and try to

 reintegrate the disintegrating soles.

Ordered a similarly priced new pair from Lazada.

My first order from L, 

but see their delivery truck around the villa frequently.

 

Wear on the VeeRubber trials tires is showing.

In past ordered directly from the BKK company 

which delived them here 

fresh off the presses 

a few days later.

They recently installed speed bumps all over our village....pa! Get up, stand up, floor it....Only at night when the kiddies are in bed.

So the oil that ran out

when the sight gauge was smashed

looked funky although it had been in there

for only a few hours running.

Will be using Shell Advance Ultra

100% synthetic 10W 40.

It is synthesised from natural gas not petroleum.

papa is believing that is about the best 'local' oil

available around here.

Using it in ceeber and Lifan DS too.

Not the Nouvo tho.

Took my Tiger down some dirt tracks today and was reminded of when I used to take the DT200R out in the wet season.  Many of the tracks flood up to the level of the foot pegs, and I used to race along them, standing up with my feet skimming the surface.  One time, a farmer had dug a trench, almost exactly the diameter of the front wheel, between the fields on either side and the first I knew of it was when I was flying through the air and into the muddy water.  The fields were empty of people just about every time I rode, but of course, the one time I came off (and it must have been spectacularly, I just wish someone had filmed it), there was a large group planting rice right where it happened.  I jumped back up, picked up the bike, kicked it into life and got out of there, because, as Bob Marley also used to sing "He who ride and run away, lives to ride another day".

Titan is 0.4x the size of Earth, about 1.5x the size of our moon, and while there are lakes of liquid methane and ethane on its surface, and about 3% methane gas in the atmosphere, there have only been small amounts of heavier hydrocarbons detected, mainly propane and acetylene - which come from UV sunlight acting on the methane.  No trace of asphaltines, as found in crude oil, have been seen.  

 

The fact that crude oils have these heavier components, which could only have come from organic matter, and the presence of shale gas and oil adsorbed to organic matter (kerogen) in impermeable shales, as well as being associated with coal beds, points to petroleum indeed coming from dead plants, microbes and animals.  There may well be, and likely are, lighter hydrocarbon gases in the mantle, but the octane equivalents I'm interested in for my bike are not sourced from there.

 

As for dinosaurs, Titan's mean surface temperature is -179 deg C (and would be even lower if it wasn't for methane being a greenhouse gas), so they would be pretty cold if they are there.  This low temperature is the reason for the liquid hydrocarbons; whereas Earth has a temperature conducive to the formation of liquid H2O and gaseous CO2, Titan's is more conducive for CH4 and C2H6, although frozen, and liquid at depth, H2O is also found.  There have never been any significant amounts of free hydrocarbons in Earth's atmosphere (read 'The Vital Question' by Nick Lane for details on how this is known, and why the "primal soup" of methane and ammonia theory for the origin of life on Earth is unlikely), and free oxygen only became abundant on Earth following the evolution of photosynthesis, so our position in the solar system, and the evolution of simple life, have had an almost equal effect on Earth's surface chemistry.

-When you reference 'organic matter" are you referencing biological-carbon/biotic matter?

Or organic molecules.?

E.g., methane, propane, long-chain hydrocarbons, carbon-tetrachloride, proteins, DNA, &c.

 

-Your argument is basically unsupported assertions you bring as 'facts'.  

Petroleum also occurs independent of sedimentary carbonaceous formations (coal beds).

[one black sheep proves that not all sheep are white]

-in abiogenic-petroleum theory, short hydrocarbons derive in the mantle from inorganic carbon;

carbonates, elemental carbon, and such.  [same same as on lizard-less Titan]

Thence aggregate into beloved asphaltines/parafins.

-Has petroleum synthesis in the lab

from dead plants, microbes and animals ever been demonstrated?

AFApK, no. No hab.

...therefore sceptical that it occurred naturally, on such a vast global scale.

papa definitely open to evidence both ways.

[admittedly tho, Shell makes an excellent motor-oil from methane]

By 'organic matter' I mean of biological origin. There are certain waxy components found in many heavy crudes that could have only been biologically produced - "The wax behind the dinosaur's ears" as my old geochemistry professor used to put it.  (In reality, very little oil and gas actually comes from dinosaurs, but some of it does come from the plants they ate). 

A sedimentary basin is effectively a closed system.  All hydrocarbons found in there must have been sourced there and migrated to the reservoir (with the exception of shale gas/oil which remain bound to their source and fracking must be done to remove commercial amounts).  Source rocks have been identified for every commercial hydrocarbon field globally - "fingerprinting" to match the oil and the source material may be done through various techniques, including NMR spectroscopy.  The Kimmeridge Clay in the North Sea being a good example, being the source rock for much of the UK's oil, and similary, though renamed as the Draupne Formation, for Norway's.

 

And a more fossiliferous piece:

As for the question on shear volume, we're looking at a long, long time.  Take a look at the White Cliffs of Dover, for example: 

Over 300m of planktonic green algae skeletons, each single one too small to see.  All the organic material is long gone now, but imagine if it had been buried and unable to escape while being crushed and cooked up.  Similarly in the Middle East, the largest oil field in the world, the Ghawar field in Saudi Arabia with over 65 billion barrels produced so far, is sourced from marine mud and lime, containing around 5% biological material.  The Ghawar Field's reservoirs are marine sands, but most of the other large Middle East fields have carbonate (dead bugs) reservoirs, including the Zakum Field off Abu Dhabi, which has over 700m of them in just one formation - think of how many microscopic bugs it took to make that.  Closer to home, the hydrocarbon fields in the Gulf of Thailand are sourced from organic rich lake deposits.  These have been cooked by the high temperature in the southern Gulf to produce gas, while the lower temperature north has oil fields from the same source type.  Thailand's other main hydrocarbon production, from the Sirikit Oil Field in Phitsanuloke / Kampaeng Phet, is also sourced from lake deposits.

The reason for the example you give, of coal bed methane, is also well understood.  Coal is dead plant matter, crushed and cooked, and, depending on the conditions - amount of oxygen, burial temperature & pressure, will produce methane in different amounts.  Coal is also classed as a sedimentary rock type, but, even non sedimentary reservoirs, such as the granite ones in Vietnam, are sourced from organic sediments.  The granite basement has been pushed up through faulting and the oil migrated upwards from the sediments through fractures in the granite, with some of it continuing upwards to overlaying sediments as well.  Although this diagram for the White Tiger Field has no scale given, the 'mature Oligocene source rock' is thousands of metres thick in places.

Therefore, even if the Earth did have an enormous lake of oil at its core, it would be irrelevant to current gas and oil production, as we know where our commercial hydrocarbons were sourced from, and it is all organic (biological) rich sedimentary deposits.

 

Finally, to get back on topic, check out the Kimmeridge Clay outcrop in the background.

Dunno 'bout that.

It's a 2 stroke.

The only lube is for the gearbox, the geared primary drive and the wet clutch.

No engine.

A lot of people & bike manufacturers stick plain old cheapo ATF in there. With success.

The thing with synthetic oils - they could cause clutch slip or drag in these old 2T motors.

Maybe.

I stick to a Veloil mineral 10/30w general m/c oil in my Yam ty250's, common, available at all good corner mom'n'pop corner m/c shops.

Only issue i ever get is the clutch plates sticking together if the bike has been sat for a while.

But no slip, and no drag problems.

 

Was out on "Bumblebee" this morning, my son's bike.

Prepping it for him and me this weekend having a 2 day training sesh.

Just brilliant fun.

 

 

[Damrongsak]

Being a bit of a dinosaur, I've wondered if the organic matter stuff accumulating between my toes would ever be of worth.  I suppose if one wears the shoes tight enough and long enough then things can happen.

 

But that takes years and even experts like you guys don't agree.  I'm more inclined to go with my gut feel, which is a vote for Methane as a hydrocarbon source. I've been a vegetarian for more years than a lot of people have been alive. Believe me, beans work. At least in a 2-stroke.

Having a problem with the Cota

The last two days 

getting ready to start the bike,

the kick lever won't go down.

papa over 90 kg.

Like the engine is seized.

Shift into 5th gear and vigorously bump her fore n aft

until the engine turns just a bit.

Then she kicks right over and starts right up.

What's happening?
