Good points.

 

Bought a gallon of Belray 2T oil for the TY350 in Colorado.

It is purple and really viscous & sticky.

Like molasses in the cool/cold mountain temps.

Used it as the foam-filter oil too.

Cut it with gasoline to apply mo bedda.

Used excess onto rag for dressing 

tools and wheelbarrow handles.

 

Also, The PTT 2T oil initially bought here

papa used to refinish old dessicated wood cabinets.

Worked great.

Better than linseed oil.

Pretty quick drying

and didn't drip off after that.

Not tacky when dried.

Low viscosity, like 10 or 20.

So prolly not optimal for filters.

In theory.

seems your dada  or mama taught you well...

Oh and BTW i've just put a 92 Kawasaki KDX 250 engine in 87 Honda CR 250 chassis...here on its first "shake down" run.

Off topic.

Been busy, life has got in the way the last few days.

# Bought the kids 3 of those fidget spinners that my son was pestering me for. Cheapo 89 baht plastic ones. Then he's showing me all the You Tube super duper ones. I said i'll make you a fancy one no one else has... Bought a 24mm bearing for 80 baht. Went into the machine shop, lathe, mill and 3-4 hours later came out with a fancy looking alloy with brass inserts fidget spinner. Except it did'nt spin for more than 5 seconds... His cheapo plastic one will spin for 2-3 minutes. Hmmm.... seems a good brg is not what is recquired, but a sloppy grade 3/C brg is. Next day back in the shop, fine grinding paste, and metal polish reciprocating the brg in the lathe to change a nice grade 1/A brg into a sloppy crap one. we now have a fancy one off billet alloy/brass spinner that, er spins...

# Got farm work to do. Cut the grass on 25 acres with the tractor.

# Yesterday my back gave up again.

#Bikes are done (my back aint though), will upload some photos later...

Photos of the spinners too , please.  You do realise you will be inundated with requests for more custom spinners.  I can see a market for you  there.  On another note , i would have a white seat on the blue bike , and a black seat on the yellow one. OMO.

[papa al]

We all eagerly await the pics.

Take care yourself.

Get 2-hr massage.

 

grease in bearing

stops spin too.

# Forgot to take pics. 3 and a 1/4" billet alloy disc, 8mm thick, radiused edges, 6 radial 18mm holes, 3 of which had pressed in heavy brass inserts, bearing was 24mm OD, 7mm thick with a 9mm ID. Then alloy 1" top hat concave spacers pressed into each side of the bearing.

# Made son watch and help most of the machining procedures. Try and get him into enjoying the machine shop - it's (one of) his heirlooms...

# Son took it to school yesterday. Yeah, now they all want one. I could probably make a batch of 10 (without the brass inserts) for 500-600 baht ea. Nobody (luckily) would pay that price for one. Son is happy because he gets a unique one off that no other kid has. "Wow! Where did you get that?"  "My dad made it"...

# Damn - another vote for a white seat....

Thanx.

# Massage could make it worse. Had the same thing about 6 weeks ago. Lower back, L/H side, could be a trapped nerve. Can't ride a bike let alone start one at the mo. Just manage to sit in a comfy sprung tractor seat...

# Indeed. M/C shop i bought it from had 2RS (rubber seal each side) bearings for 40 baht or ZZ (metal shield each side) for 80 baht . In hindsight i shoulda bought the cheapest nastiest brg i could find. These spinner toys sold use bearings which would be considered junk for most applications.

# Shields came off, grease cleaned out, and the bearing went in and out of my lathe about 10 times until i was a bit happy with it's "slop".

[thaiguzzi]

Speed Blocks. Lots of Speed Blocks...

Tools of the trade...

# Top is a long piece of 1/2" square tube welded to a nut with 22mm across the flats. Fork damper rod tool to enable the fork legs to be put together.

# Below it on the right is an alloy fork top bush and seal driver.

# On the left is another home made tool, made in my workshop in the UK for holding Spanish 2 stroke flywheels. Unfortunately, the flywheel weights get in the way on a ty.

# So i had to buy the tool below it from the UK. This is a monster (pics don't do it justice just how big these are) pair of mole grips type tool which will hold a flywheel for nut tightening one side, and the other side for holding a clutch centre for nut tightening. Pretty much a universal tool for anything it will fit. Very handy. About £18 plus shipping.

# Bottom right is a std L/H thread flywheel stator puller, fits most off road Yams, and available at most good Mom'n'Pop local M/C shops, about 350 baht ish. About the same price in the UK.

The foam air filter oil debate;

Well, in my 40 years of working on motorcycles i have never had a bike with a foam air filter, hence knew nothing about them nor the oil recquired.

I tell ya, and any unbelievers, there is NOTHING like this stuff i have ever come across.

Make sure you have a good supply of surgical gloves handy...

Sticky ! Tacky !

A little goes a long way. I am converted.

990 baht for one litre, Mr Moto Sports, Udon Thani city centre. Bargain.

 

[thaiguzzi]

Bikes were weighed.

Dry, no fuel, no oil (well, 0.6 of a litre of 10w fork oil per bike don't count).

39/46 front rear ratio = 85 kgs. Both bikes identical. That's 187 lbs in old money.

Slightly disappointed, was hoping for low 80's, 82-83.....

I oil my flters in a large sealable - zip lock - bag that is then kept in a sealed "Tupawear" tub to prevent evaporation. Motul is my prefered brand , or Silkolene. I know you have problems sourcing spares where you are , but my choice of seat colors would be   powder blue , or second , white on the blue bike , and yellow , or second , black on the other. Just depends on what YOU want ( these are your bikes afterall ) and whats available.  85KG is good , but is that with all the speedblocks ?.

# Yeah, seen that on You Tube. Seems a lot of people go by that method. Next month, new UK order, will order 2 more air filters as spares and have them ready oiled sitting in a sealed bag.

# Brand name wise - as long as it's a proper brand, and more importantly for me, i can get it locally, i don't care who makes it. Having said that, being a virgin in the foam air filter oil game, i am impressed with this Motul stuff.

# You can buy seats in the UK around £55 a pop, but not in the colours you are suggesting.

# Seats are recovered locally, 7kms away in my local market town. He does an excellent job, 150 baht for a ty seat. 300 for my Triumph seat. Any colour you like as long as he has the materials.

# Yeah, 85 kgs is ok, the best of the last of the twin shocks weighed similar, as did most air cooled monos. Weights started to come down in the early 90's with the advent of alloy chassis parts and liquid cooled motors.The latest current trials bikes, depending on model and spec weigh between 67 and 75 kgs...

# I'd weighed them last year, with oil and a bit of fuel, 86 and 88 kgs, and was hoping what with cleaning the ex header and mid box out, dumping the stock steel ex end pipe and replacing with a much lighter alloy DEP unit, and cutting all the excess brackets off etc etc, of saving a few grams...

  ... maybe i put too much air in the tyres....

Very impressive. Wish I had the skills to do something like this. However,  my skill set is limited to filing my nails and general procrastination.

Just make out the TY embossed on the original (lovely condition red) seat underneath the new dimpled black cover.

Stock for a lot of the bikes around this time, and i still think some are, is the daft, nay stupid factory kick start stop arrangement. The stop is the footrest. Never liked that, wacking the footrest every time the starter comes down. I had a go removing the footpeg return spring and lifting it out the way, but that idea did'nt work because of the lowered brake lever in the way. So i cunningly made that rubber and alloy bump stop visible directly below. Rubber is off a truck shock absorber. Never throw anything away.Works a treat. Kick start lever stops about an inch from the peg now.

 

[thaiguzzi]

Air cooled 2 stroke motor... Yess!!!

 

Stock those sump plates do not have any holes in them...

 

[Morch]

Great read, thanks. And great looking bikes.

Not even into that, better at falling off them - still enjoyed following the project.

And as said above, wish I had half the skills (and motivation) to carry out such a project.

[Dutchbike]

For this whole thread and all your hard work my compliments they look really impressive

My compliments!!

 

[ktm jeff]

Well done. Both bikes are superb - i knew they would be . Trying to imagine the bikes with my questionable seat cover color choices.  You may be right !.  Glad you finally mastered the "speed blocks" . Those sump guards / bash plates look heavy duty. does "ol blu" lean over more on the side stand.  Enjoy riding them with your son.

Sorry, had to stop posting earlier on, did'nt realize it was 15 minutes past Chang o clock.

Whatever i do, if i'm home, 5 o clock is stop whatever it is i'm doing and go upstairs onto the balcony, look at the same view i've looked at in the last 12 years, and drink two bottles of Chang and smoke cigarettes and contemplate. Contentedly. Every day.

 Couple more...
