20% depreciation @ purchase 

and 1 baht per km.

That formula makes my daily rider worth minus 8000 Baht whereas it is actually worth between 40 to 50% of the purchase cost.

On most manual gearboxes there is an oil level plug.

You fill up the gearbox until oil just starts to run out of the oil level hole and then replace the level plug.

The fact the 'mechanic' put PTFE tape on the drain plug suggests to me that the replacement drain plug was probably the wrong thread.  So if you were rebuilding the original gearbox you would probably have to repair the threaded drain plug hole in the gearbox casing.  That would be a job for a good machine shop. 

I am pretty sure that is a pulse pump.  It works by using the variations in pressure in the inlet manifold or, less commonly, the crankcase.

I have never seen one before on a motorcycle.  Pulse pumps are commonly found on lawn mowers and general purpose engines such as the Honda GCV.

There are three connections to the pump:

1.  Fuel in

2.  Fuel out

3.  Pressure from inlet manifold or crankcase

If the mechanic has got the hoses mixed up or there is a leak in the air hose the pump will not work.

There isn't much inside the pump.  A spring, a one way valve and a rubber diaphragm.  Assuming it is not spanner monkey error it is probably a defective diaphragm.

And, as others have said, it certainly isn't a 10K part.

Our Wave gave us 202mpg when it was new...

You have me beaten.  I only (!) got 199 mpg from my Wave 110i when I was running it in.

That's proper gallons of course.  Not the itty bitty American ones.

Carb setting:

1.  Get the engine up to normal temp then set the idle rpm using the screw with the spring on it.  You do not have a tacho on a Wave so what you are trying to achieve is a stable idle.  You can get an idea of the right sort of rpm by listening to other Waves (ten on every street corner).

2.  Set the idle air/fuel ratio with the other screw.  Normally there is a base setting for this but I do not know what it is for a Wave.  A typical setting would be one and a half or two turns out from fully in.  Then try turning the screw further in (weaker mixture) or out (richer mixture) until you get the highest idle speed.  Bear in mind that this screw only affects mixture at idle and not throughout the range of throttle positions.

3.  Revisit idle rpm which probably went up as you adjusted the mixture.

Ignition:

The ignition system is very reliable and has no adjustment.  There is a small black box that controls advance/retard.  Check all electrical connections are good (just pull them apart and push back together cleaning if necessary).  I use a strobe light to check for misfiring throughout the rpm range but it is probably forty years old and not easy to find one here.  A strobe will also show you if the advance/retard is working.

New carb:

Not a bad idea and probably quite cheap.  Only consider a genuine carb that is correct for your model.  Any Honda dealer can supply.

Air leaks:

I think on your generation Wave the carb pushes into a rubber mount.  Make sure there are no splits or leaks from this part.  You can check for leaks using a small can full of petrol but I am not going to tell you how in case you sue me for the hospital burns unit bill :-0

Valve clearances:

I have never seen a Thai mechanic adjust valve clearances.  It's a little bit fiddly and you need a set of feeler gauges.  Inlet = 0.10mm.  Exhaust = 0.20mm.  I think.

Thai mechanics:

Generally speaking Thai mechanics are the problem and not the solution.  If the bike is not running right it's normally because they have screwed up.  Stripped threads and missing fasteners?  Thailand's finest at work.  On one rare occasion when I let a Thai mechanic touch one of my bikes the cost of the parts he broke exceeded the bill.  I do everything myself.

Good luck. 

Checks that you did not mention include:

1.  Carb float height

2.  Air filter

3.  Fuel filter

The one with the spring is idle rpm.

The one without spring is idle air/fuel ratio.

But I doubt adjustment is the solution.

Sounds to me like you got a half-assed job in terms of cleaning and checking the carb.

Cheques and bank transfers to be made payable to a man with the first name General at an offshore account.

Yes, exactly.  

At 3.00am or 4.00am perhaps on the right road.

Why?  One reason would be to get to your destination quicker.

I agree Mortenaa.

This was what I wrote at first before posting:

"And I agree with the majority that you would have to be nuts to want to use 200 kph, other than in limited circumstances, in this driving environment."

In editing I probably over-simplified.

It's mostly to do with taxation.

And I agree with the majority that you would have to be nuts to want to use 200 kph  in this driving environment. 

Home Pro sell white PVC water pipe.

I am not sure what their largest size is.  

They certainly sell half inch and three quarter inch but I cannot remember if they have one inch. 

Not much point to the show without some eye candy.

"Look over there Somchai.  That's a Revo.  Never seen one of them before."

"No wait Sombat.  That's a City over there.  Maybe it's new and improved but somehow still utterly dreary.  Let's find out."

My vote would be for the Suzuki Swift or the Mazda 2.

Don't sit in the back of a Honda Brio hatch unless your name is Crumple Zone.

When they started wittering on about ancient powers of the monarch they were screwed.

It makes crystal clear that the army's role is internal suppression.

Though we knew that already.

If I had to have a truck comparable to the Thai trucks and could choose from anywhere in the world the Honda Ridgeline would be my pick.

Unitary chassis instead of the primitive ladder chassis Thai trucks come with.  Independent suspension front and rear.  3.5 litres of Honda V6 making 286 horsepower up front and 4WD as an option.

They sell it for $30K in the US with US production costs factored into the price while we get cave dweller stuff here for the same money.

Given that the X type in based on the Nissan truck sold here maybe the Thai budget option will be to nail a three pointed star onto their Navaras.

It had me so fooled when they used to do that with the Ssanyong.

And the Mountain Dew bottle swinging from the rear bumper.

Or is that just for rednecks?

For the X type to succeed in Thailand it would need a range of genuine Benz sticker options:

"Rescue" tailgate sticker.  50,000 Baht

"Liverpool FC" rear window sticker.  50,000 Baht

"Cartoon boy urinating" tailgate sticker.  20,000 Baht

and the ever popular...

"VIP karaoke" side window sticker.  10,000 Baht 

The fact that every Thai truck has a live rear axle with leaf springs locating it undermines any claim to sophistication.

Historically the USA has made a huge contribution to democracy and freedom in this world.  

Not least in World War 2.

I say that and I am not American.

Not my opinions.

A test by US reviewers.
