Clive's JMC Frame

[clivegto]

Slots cut in the spacers forks fitted to yokes.

Lovely looking frame there, will follow with interest

Head stock bearings arrived today. To fit the eccentric head stock stem I made a couple of spacers up as it's too long. I'll get a shorter one made up later also the top head stock has slight damage where it holds the bearing which needs a repair. Fitted the forks for mockup.

That looks very upright " i guess it's the way frame is sitting"

Yes.

Don't look like there's much lock to lock but maybe camera angle

This is what I'm going to work from for the angel of the dangle. Forks do look steep maybe just need to be longer.

It won’t be a slouch with that nice steep angle

Might be a bit wobbly at high speed when coming on boost though

 Could be a bit twitchy

Didn’t think they twitched that much with the wheel in the air………

Does the bike in the picture above have adjustable yokes/headstock? I'm puzzled as to why the forks aren't parallel to the headstock?

Fzr1000 tank?

Late to the party but i finally measured one of my 90 1k tanks, it would fall through the frame spars.

So that nice man Mr @Allspeedsfound a old Streetfighters issue (185) with another JMC frame bike. Cheers mate.

Dropped the frame off @clairetoojust before Christmas to fix the top steering head bearing housing. Picked the frame back up at Newark Classic winter bike show at the weekend, she's machined the bearing housing out of the frame made a new one heat shrunk it into the frame and welded it up. Also removed the silly front tank mount that was pop riveted on and filled the holes with weld as well as welding a crack on the bottom knuckle mount where it had been over tightened and she's shortened the stem as well, she's a clever girl  and I'm a lot happier now     

[clivegto]

Did have it on display at the show as well.

From that angle, it looks a bit like a Bimota YB4 series frame

Havoc and I came to to conclusion it looked a lot like his Bakker frame while we were stood pondering at the show.
