papa acquired a trials type motorcycle about a month back. These bikes are best for going slowly over difficult terrain. The bikes are ridden standing on the pegs. Quite a challenge for an age-chal

Had a full hour with my lad this morning. 60 mins is enough at this time of year - gotta be done & dusted by 9 ish. Great fun, he's getting better, even jumped 3 big bunched together bra

Stand up when you ride ...

# Re the CM training camp, not only anecdotes, some pics would be good also.

# 80:1 is fully synthetic only, preferably in a water cooled bike. 100;1 definetely water cooled and with a chrome nikasil bore as per modern bikes. Mineral oil in an air cooled motor with looser clearances i would recommend not leaner than 50:1.

# My ty250 yams are running 50:1. I might up it to 60-70:1 IF i could locate a high quality brand name fully synthetic, which i can't.

# Bultacos and Montesas back in their heyday ran 40:1. Before the advent of semi and fully synthetic oils.

For 2T I would use

Shell Advance VSX 2T (Black Can)

Available at most if not all Shell stations and has good lubricity. It is semi synthetic which doesn't mean much as it is neither fish nor fowl but It is good and available.

Ratio? Your bike is air-cooled at although it won't be at max power for very long it also won't be getting much flowing air for cooling so I would stick with your 40:1 that way you can add 500ml to 20l of fuel in a 20l can. Easy!

If it smokes reduce to 50:1 by squeezing another 5l in the can or as much as you can.

Oh and don't forget to add a cap-full of Castor oil to the tankwhistling.gif

Ive always had good results with Castrol "Power 1" Racing. Was called Castrol TTS. Fully synthetic. Even at 25:1 , very little to no smoke. If this isnt easily available , then fully synthetic Shell.

^ Never seen Castrol RS here or Shell Ultra. That's why I use VSX. Recommended to me by the guy who built my motor. As I said available most everywhere and a 500ml bottle will fit under my seat, just in case. Used to be sold at 7-eleven but...

That being said Papa will not be touring so if he can find something better locally...?

VN: "500ml to 20l of fuel in a 20l can. Easy!"

papa acquired a real nice 2-liter bleach bottle for T2 mix.

Not too keen on keeping 5 gallons of gasoline in my condo.

So far I've added 1.5-litre of benzine/oil to the small trials tank.

Capacity, dunno.

Still drawing from valve @ main;

not reserve yet.

papa will buy 2 litres when dat.

Already bought 500ml of some regular certified song tee.

Used half of it to refinish some wood cabinets on the balcony kitchen

that had dried out.

Two coats; they look great.

Oh, the red bike depicted in OP is not the bike referenced.

A troll bike, I guess.

Cool looking tho.

Standing up is useful on bad roads and off-road too. Helps identify surface problems early. I do it all the time when riding below 100. I've also found that if I use the rear pegs I can stand at up to 140. Applied with cation…

Now you'll need one of these. laugh.png

A proper "red" gas can should be OK if kept outside on the balcony. Although 2l of bleach attracts less attention in the elavator/Lift whistling.gif

Only stand up to relieve crap and to gasgas. Years ago had a 350 Aprilia trials bike, no seat at all, made one and changed the gearing to use on the dirt. Looking back it was so easy to ride standing up, no bike experience, but maybe I had natural talent then..or maybe not. But also looking back that was a really great bike, bucket loads of torque.

I am sold on dirt bikes, on road off-road, or on a building site....Duggy Lampkin rules, well he used to.

Been getting some rain here in patty.

Still too hot.

Usually try doing my crazy falling riding

[ha ha , i typed 'Farang' and auto edit put in 'falling']

in the undeveloped parcelabout 0730

before hotting up.

Also good comic relief for the Thais riding past

on their way to work, school, &c.

Rode in afternoon twice after rain showers.

The tires still grip well on the wet weedy dirt piles.

Recently purchased a gopro-copy type cam so possibly

will have something like that to post in the next 2 weeks.

This type riding is a lot of fun.

Starting to get it.

That Yamaha 142cc 2T is a great little plant.

Very crisp throttle response.

Smooth.

Don't have to use the clutch too much.

It will definitely lurch you onward @ full twist.

Fingers on the clutch 100%....

Not neccessarily. There is old school and new skool.

Old school, is pre 65 and twin shocks, heavier bikes, more low down torque, heavier flywheels for more traction, less "trick" riding, no hopping etc.

New skool is the opposite, and yes you'll be using the clutch constantly.

Me - i'm too old a dog to learn new tricks. Plus a lot of that new stuff scares me.

The Bulto and Monty pictured in your post above - check out YouTube footage of that era. Once in a section, nobody has got fingers anywhere near a clutch lever. They did'nt need to.

Now go and watch something current of Tony Bou et al or even Dougie Lampkin from 15 years ago - it's constant one finger on the clutch action. They need to.

Yes thats true, just its better to develop good habits instead of bad, very hard to change once they set in, as per my post, I know its better but I still have to force myself to stand up. but it would seem p a is not interestedunsure.png

Saw this on YouTube.:

Using single-finger clutching?

Why not use a short lever, just long enough for one!?

Reports much less effort n fatigue.

Where is my hack-saw?

All right.

Very happy w/ this air-cooled mono-shock trials-bike scenario.

Thinking maybe need one for

the time I'll spend in Colorado this summer.

Yamaha YT350 for example.

Develops maximum torque @ 2500rpm.

Seems about right.

I've got four of them (250) here.

The motors are fantastic.

The only thing i can't get my head (feet...) round is the ridiculously high old school footpeg position. Once the frames are stripped for painting and cutting off various street brackets and mods etc, the pegs will be lowered to just above the sump guard for a much better c of g, and at the same time, modern mounts welded on for modern, wider pegs.

Apart from that, you're good to go.

Unique to these bikes, i presume by the time patents ran out, everybody was using disc brakes anyway - 32 hole rims, 16 spokes, 32 nipples....

First day riding this bike papa met, another guy who has the exact same.

He has all the expertise and jets, etc and will help me tune to altitude.

What luck.

Turns out my new found biker buddy is a fanatic.

He has about a dozen ready-to-ride dirt bikes in his shed.

3 trials [1 new. 2 classic]

and a bunch of enduro types.

A lot of Husquevarnas 10-20 years old.

papa will try to ride up Mosquito pass today on the TY350.

Over 13,000 feet above the sea.
