Get up, stand up. Stand up when you ride.

Could a piston ring be broken , or seizing / jamming on a port. Unless its a problem with the kickstart gears not cleanly meshing . I would strip before using. Could be cheaper than breaking something.

[papa al]

ok thanks.

Have ridden it 2x 

like an hour + each x,

on enduro terrain

runs great.

When it's not locked up,

it kick-starts fine.

maybe something loose in there.

 

Climber is still down.

the sight gauge that was broken 

2 weeks ago

part did not come in,

maybe two weeks more...

 

 

[canthai55]

Possible the shifter forks worn and/or bent.

Not allowing the gear cluster to fully return to neutral.

When you rock it, the cluster moves via the rear wheel motion and hits neutral.

Maybe ...

[thaiguzzi]

Yeah, what they said.

 

If it runs great, i doubt it's piston / barrel which on a Cota is iron and steel rings running in a Nikasil type bore.

If it runs great thru the gears & good gear changing, then the suspect is more likely the k/start mechanism. 

Get it to your mechanic dude and remove the cover on the k/start side for a peek inside.

Possibly (hopefully) nothing more serious than a loose nut on a shaft.

First thing in the day it is locked, again,

but free-able with bumping.

Thru the ride can re-start normal.

Very weird.

Holding off taking it in until 

Climber is back in service.

If part/site-gauge is not in next week,

guess will try and fab something with

epoxy and old specticle lens.

Open to suggestions.

 

Cota, the entire R case needs to come of with water pump &c.

Would like to have a new gasket on hand.

Been fun riding Cota more lately.

Just need to beware the whiskey-throttle.

All the venues and obstacles look the same.

Even as a trials enthusiast, i find it utterly boring and predictable.

Best you get a gasket sorted ASAP.

Either a genuine one posted to you or find an auto factors locally and buy some gasket paper and make one yourself.

I would be loathe to continue riding, until further investigation.

The problem/damage may get worse, ie more expensive.

Not to mention getting thrown out of PowerBuy for trying it with their fridges.

I included this picture in a post on the bike porn thread, but felt it should be here as well.  Trials biking in 1921.  See the other thread for details on the rider.

Went to order Cota gasket today.

The Climber site-window-gauge was in;

[two actually ??] B520.

Looks like it just pops in.

Mech removed the R case for the repair.

The bashing of the window had mushroomed the metal around the insert.

Removed with difficulty then needed to reem before installing new.

Inspection by mech found another bashed spot

that maybe wasn't leaking but was cracked

and spalled so they TIG repaired that. 

He had a gasket on hand plus

~2.5 man-hours=

Good repair job. 

440tbh,

papa supplied the 0.6l of oil...

Shell Advantage 100% synthetic 10W40.

[derived from natural gas/methane]

Field test 3 km trail showed the tyranny, clutch good operation.

Engine wasn't developing power right tho.

Maybe air-filter, but that actually looks okay.

Will try new next time.

Could exhaust system be clogged.?

 

 

[papa al]

Ordered Cota gasket last week;

today shop says 'cannot;

no Thailand' supply.

Ordered one off EBay.

GBP12.29 delivered;

3-7 weeks.

She hasn't seized up lately.

Changed the Climber

mushroom-type air-filter.

It was loaded.

Sipped a thin sock over the filter

and secured with a rubber band.

Like a pre-filter.

Easy to change daily or whatever.

She lan rike a laped ape after.

Been running Motul synthetic 2T oil.

B450 /l.

# 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.

What would the advice be for a Kawasaki GTO ?

[papa al]

Advise: let papa borrow for a couple of hours.

What the manufacturer recommends.

I presume it being a street bike it still runs an oil pump, so no pre mix ratios recquired.

Just fill the oil tank up with whatever is commonly & easily available, the best being the Shell (VSX?) in a metal can.

There is no bad stuff, it's all pretty decent.

We've had unseasonal rain lately.

Was out a couple of days ago after a heavy downpour during the night.

Slippery tree roots on a couple of sections i always start out on had me all over the place.

Even complete ground covering of wet leaves makes you re-adjust your riding style.

 

You can see why the Spanish riders that have dominated World Trials for the last 20 years, don't like coming to wet and muddy and slippery England....

They are used to dry rocks.

Prolly same as east & west coast riders in the States.

One set of riders used to wet conditions and the other set only used to dry rock climbing. And the dry condition riders being completely out of their depth in the wet slippery conditions and the wet condition riders loving the extra traction of dry sections.

What psi you running in the tires?

Rode up and down Doi Khun Tan. Road new asphalt on both sides, but a windy day had the road covered with leaves.

Greasy ! Stabbed my leg down more than once when the front washed out in a corner.

Even at crawl mode.

Depending on which way the wind is blowing.

Or what i had for dinner the previous night.

[papa al]

Same ish here.

Splane this:

A few days ago,

went to start the Climber.

Top with fuel; cock from off ==> run.

It wouldn't start.

No firing atoll.

No-choke, choke, throttle off, full, ....

Bumping in 3rd.

Even pushed down the road a bit by a nice by-standing Thai guy.

popopopopopopopopoopop

Zip. No fuego.

It's really hot, 

papa sweaty & say bad words.

Okay, put her away and ride Cota.

 

Yesterday.

Gas on, one kick.

VROOOM.

Sometimes papa feels like he is

the subject of some alien lab experiment.

So the air filter on the Cimber 

usually loads up after a few hours on these trails.

Can replace for $5 so no biggie.

Rode in sand yesty.

The old-sock-hillbilly-pre-filter/condom caught a lot of brown.

 

Also, After dissecting one of these filters found them good quality.

Like K&N knock-off.

The filter element is fabric bonded between two metal screens.

 

 

 

I think I’ll try washing & oiling the mushroom/pod next time it gets dirty.

Dude,

get a TriCity if you want stability.

If you want wide, heavy, clumsy and Fugly ...

I agree

Want stability - drive something with 4 wheels.

Want to ride a bike - see if it has 2 wheels first - one in the front and one in the back
