Mike Hann of Bishops Caundle used to do a Fantic '200 special', a 200 motor squeezed into a 125 frame. I seem to remember it was very competitive in the day. Just a thought.
Mostly curious...I was wondering if anyone know anything about the thread on the spokes and wheel nuts on a tubeless flanged wheel? I know the threads are rolled instead of cut (easier / cheaper / more robust) but thread standard metric size, imperial or some special secret type used only for spokes?
Thanks.
I've just had a check on this and they are M4 X 0.7
It sounds like your friend bought the bike and had it running for a while.
Then decided to tune it up and maybe improve it some what ?
It sounds to me that in the process of changing the jets the tune was made worse.
You had it brought around to yours, whereupon you rode it around the yard, proving that it still ran okay but gave it a 'handful of revs'.
In the past on a new 1979 Montesa 247, I went through quite a few woodruff keys.
Perhaps it was just an unfortunate failure of the key due to over revving, exactly what it's designed to do.
If the key had failed in the past then any previous owner would surely have replaced the broken key, smoothed over any rough divits and reassembled, just as you yourself have done ?
The key is far softer than the crank or flywheel and should, in theory, not cause too much damage.
Some pictures would be great.
I presume the rest of the bike is a shed of a restoration too ?
So who will be the first owner to lay out a couple of sections in the local club trial at which only they can ride, a nifty way of winning a trial I fancy.
In fact if it's the last section you'd have not only cleaned it but you and the bike as well !
Montesa 349 mh front wheel hub help!

I bought a brand new 349 once on the first day of two weeks leave, within an hour of practice the hub shattered.
The local trials shop laced a new one up the week after but all the spokes came out of the rim at the wrong angle.
Another week went by and Sandifords put it right.
A whole two weeks of freedom with no trialling, it was depressing
So on that note if you'd like to send it to me I would love to vent my anger out on it with a sledge hammer !
