Just waiting for the engine cradle and head stay so I can line up the lower engine mounts and weld up.

Excellent work. Nicely done.

I would love to say it's my welding but alas it was done by another, my good mate George, 'welder exordinaire' and general mechanical 'wizard' and all round mechical guru.

The down tube is excellent. It was replaced with tubing from a DT250 (already 'butchered' by person/s unknown (not me  ;D)). Both are 29mm. George v'ed the joints, welded up, ground back and even without paint you cann't distinguish the weld. I am worried about the strength but I'll keep an eye on it in use (one of the reasons the frame will be painted not powder coated). But I'm probably a 'worry wort' (but having your down tubes fail after coming off a jump at speed and having your engine disappear under the back wheel would not be a pretty sight nor an experience I care for  ;)) - if Georges says its done right then its done right.

George wanted to replace the rear loop completely but I talked him out of it. I didn't have the tubing and it was more trouble than it worth for a race bike. Maybe after everything is up and running I'll come back and finnese (another good reason for paint over powder coat).

Sweet.

This is my first Spanish and obviously my first Monty. I rather impressed with most things regarding the Monty. Looking forward to firing her up and going for a lap or two.

Back in the day I didn't look at the Spanish. Although always light they had the reputation of doubtful electrics, dodgey carbies, fragile mechanical and the doubtful pleasure for a MX'er of primary kick start  (backed up by not having big name riders or big name wins - no 'cool' there ;)) - and all this pleasure for a third in price premium.

I may have been blindsided to their charms. ::)

Very NICE Graeme. Why on earth was the down tube chopped!!?? You've really taken on a challenge there and I bet it'll end up a beauty! ;). Lyall O'Brien told me that the only way you'll lose a motor is if the things sucks air. You're already on that so it's gunna give you years of joy. Make sure the fly-wheel's a good fit, plenty of Loc-tite everywhere, lock nuts and you'll give ya other bikes away! They really are giant killers......... ;)

When it finished I might christian the thing Lazarus. ;) ;D  But coming from me that might be considered blasphemy
by some  ::). But it gonna be called nothing other than a piece of 'Spanish crud' until I finish it  ;) 8)

Here's the story as told on the previous forum I believe;

"I thought I would put this out there as way of explanation of why
I'm so vague about all things Monty and this bike in particular As
I've said before this is my first Monty and in deed my first non-
japanese bike, road, trail or mx (except for the old El Paso (Duke)).

A local ad 'Yamaha RD350 engine and parts, $150'. It's nearby so I
call. Go around.

Me,"yep, I'll take them!"

Owner, "Okay. But you take the lot or nothing" he points to a corner
of the garage piled with the remains of several bikes. "My lease is
up and I'm moving out this week end. Either you take them or they go
to the tip".


It's a good thing I drive a ute.

I load up the bits, the engine and a lot of old DT250A rubbish,
frames (to become a source of down tube steel ;)) engine etc
- and the remains of the Monty. The frame is
butchered where someone has cut the left hand down tube and welded
in (badly) a square section of angle iron to form a box in the down
tube. There's an old side port, round case Monty engine included so
I guess that someone has tried to fit an old Monty side port engine
into the centre port frame.

I finish packing when another punter turns up - he's particular
interested in the Monty engine, he is disapointed - Me "$150 and it's
yours!"
Him, "Done deal". So I end up with the Monty frame and bits
and a ute load of Yammy rubbish for nothing!!!

The thing with this Monty frame is that it is TOTALLY pulled down -
not into sub-assembles but pulled down into every constituent part.
For example the brake backing plate, the shoes are off, the cams
out, even those little plates on the end of the brake shoe are off
and floating around in a box of bits, screws, bolts, nuts and all
manner of unfamilar dovalackies. All bearing are out or off every
component. Why? Stuffed if I know. And evry thing is old well used
and dirt, greasey and rusty.

This is not a 100 piece jigsaw it is a thousand piece jigsaw.

I'm still not 100% sure what I've got. Iv'e got obvious enduro bits
and obvious MX bits. I've got two ignitions. A lightweight MX and
the heavy Flywheel off the enduro (I deduce).

Slowly I'm putting it together and making sense of it all. (without
a manual). With a bit of help from you guys I might be able to get
this relatively rare (compared to my Yammies) beast back up and
running as some sort of period representation of a classy Montesa
(if not perfect resto).

I'm also interested to have a ride - one way to experienced the
fabled handling of the Monty."


So I basically had the frame, as seen above, no rear suspenion, rusty front forks, the wheels and a damaged tank. The cost of this was essentially zip. However, my guessimate to get this up and running is $2000-3000 (likely resale value, $2000 on a good day after a long wait).

Insane; yep, I feel it at times. But I am expecting a sainthood and honourary Spanish citizenship upon completion ;D.


Lyall O'Brien told me that the only way you'll lose a motor is if the things sucks air.
Do you believe him?  8) ;D 'Done and dusted'  ::)

You're already on that so it's gunna give you years of joy. Make sure the fly-wheel's a good fit, plenty of Loc-tite everywhere, lock nuts and you'll give ya other bikes away! They really are giant killers......... ;)
Thanks for the tips. You might find a few PM's and emails headed your way as things go along.

Here's some shiney bits just back from the zinc platers (Blu-Chrome Bankstown).

Not N.O.S. but nice and clean and done for $50.

I've brought VB cases, barrel and head, and some gearbox bits from BigK here, and have agreed to take a complete VA engine "Brand New" from someone up Newcastle way. I'll make arrangements to view and buy as soon as I can,

1/ get the time and
2/ prise the money from my wife (the tax cheque ;D aka budget surplus ;)).

I've been concentrating on the frame and swingarm. I hope to have a rear engine mount and head stay from Jared shortly which will allow me mount the engine. I hope to have the engine and the parts in a week or so, engine mounted within say two weeks.

I'm undecided yet but I'll have a choice; put the VB barrel on the VA cases and weld VA corresponding mounts, or swap the VA internals to the VB cases and weld the mount to accept VB cases. This is complete undecided and unaddressed. I haven't even got to the stage to confirm the possibilities. I understand the VA/VB internals and barrel swap but am not certain.

....and pesty Yammaha riders want me to check my stock of goodies so I can sell them stuff  ::) :P

I do have a standard 360 VB pipe that needs a little attention. I was going to stick it on E-bay however if you want it we can work something out......

Is that frame a VB or later? Looks like it from the shock mounts. How much of it was there when you bought it?

I'm following this resto with great interest.

By frame number it is a VB250.

"So I basically had the frame, as seen above, no rear suspenion, rusty front forks, the wheels and a damaged tank." as in the post above replying to 414. Not quite 'I started with the front axle' rebuild, but close - and to think I'm not even a particular Monty fan  ;D
