I'd definitely remove the ring at the base of the schrader valve. If the tube does move it's best not to have that in place as might tear the tube off the valve.

Yes, you just collapse it into itself.

If you're buying the complete front end then it's basically down to the fitment of the triple clamps into the 315 frame. You might want to ask what the measurement are between the clamps and be prepared to be on the hunt for different head bearings. I wonder if the 4rt clamps are a direct swap.

This is a Jotagas rear wheel with a later model rear caliper in the 'wrong' bike. It just took a load of measurements, home made spacers, a touch of filing and it lined up nicely. The front forks and clamps are 40mm Marzocchi from a Gas Gas. Stuff will generally fit but it takes a bit of searching for the measured part you think will fit, such as alternative bearings and spacers.

No worries, I can remember at the time, being quite concerned about it and wanting to make sure all us Firemen wore breathing apparatus at any possible fire involving carbon fibre. It's great stuff but not when it burns, a bit like that once wonderful material called asbestos!

I seem to remember that when carbon fibre is involved in fire it releases micro hooked fragments that just love to lodge in lungs. Potentially quite a serious problem for Firefighters due to modern car design and other forms of construction. Not that in a silencer it would be directly involved in a fire, but it's close enough to be degraded and shot out the tailpipe with the heat that is produced. Just a thought !

No, it's good to go, I swapped it for a Keihin out of curiosity. If you're interested, message me, I'll strip it and send some pictures.

I've got one ! I was keeping it as a spare but probably won't swap it back again. ?

A good result !

NGK LZFH perhaps ?

A low profile, 90' plug cap might do the job at first glance.

Rightly or wrongly I always use ptfe tape around bike or car bleeder nipples to try to stop the 'false' bubbles. It usually does the trick for me when vacuum bleeding.

Looks to me, from the photo, like it's possible but with both bikes at an angle, on full lock and with the handle bars dropped ?

I always liked the look of the red JCM that Tony Scarlett rode, at the time it looked very light, slim and the bike to win on !

The early ones had a Tau engine, I'd a 323 at the time. The later newer look bikes, I thought, had a Gas gas engine, never heard of the Yamaha motor though.

I can remember JCM parts were difficult to get, even back in the day. I'm sure it was Quinns in Gateshead that imported them. There's probably a bunch of generic parts that could be sourced from other bikes of that period.

Fairly sure my Montesa 330 came out of the box with a plastic shield, was ripped to shreds in quick time so I made my own wrap around alloy one.

I can't give you an answer on that, but I once bought a "240" JCM monopro from a well known dealer, got it home and stripped it, only to find an unusually large piston within. It was a 323, I wasn't too happy. So it's not a stupid question !

Could it not just be, hopefully...... the woodruff key ?

If I remember rightly the 84 model had a gap at the base of the frame's headstock, the later model had it 'filled' in. At the time it was a known source of stress cracks and I can confirm that as mine went that way too. It just needed a good few welds to fill it in and give the area a bit more strength.

Shouldn't be too difficult for someone to identify him, a whopping nose and a very small pudding bowl hair cut. Scum.

Have you tried setting off down a slope or giving it a push in neutral then without using the clutch, pop it in gear. Ride around for a few minutes, warm it up, using the clutch lever, then see if it'll disengage smoothly ? Might have to use the brakes against the clutch. Probably not as simple as that though !

I've drowned several Montesas over the years, the first one I pushed home and the next day emptied out what water was left in the crank case. A new set of big end bearings swiftly followed my costly mistake. Since then I've always had the bike immediately upside down, spark plug out and turned it over for several minutes, then a quick strip of the float bowl. You must've been in pretty deep to affect the upper electrics, hence my story. In theory the breather pipe should be the only way into the casing if that's the source of your troubles.

If your new handlebars are the of the fat variety then you will most likely need a set of adapter mounts.

I bought mine new, way back when, and it looked awesome, yours is heading that way The front forks on mine were red with black hubs and gold rims. The foot pegs were horrendous and made of butter. Oem was definitely not best !
