Evening all. Daft question but as the one that came with the bike was glued to the headstock I suspect it shouldn’t have been there but I have no idea where the VIN tag goes

Is it headstock job or is it one of the rear frame rails for this year on the off side?

Anyone got a piccie?

Only the US imports got a VIN plate Roo, there was a black and chrome sticker on the headstock that said Made In Japan though.

UK model F2's have a VIN plate. It goes on the off side on the downward rail at the back of the side panel. There should be 2 little holes for the rivets.

Afternoon all.

So I’ve got the twin calliper’s on the front of the 550 but thought of a question whilst driving about this morning in me digger.
Is it the done thing to use two of the rigid brake lines to mount onto the calliper before using braided lines there after?
Also,  twin lines or single to a splitter and a separate line to each calliper? Has anyone had good results with either methodology?

I’m going to have to get some wire out tonight and see if I can get a length for the different lines as my heap didn’t come with brake lines attached hence the ask.
Obviously if using two of the solid lines means my braided ones will be shorter, I can’t see any advantage in using them but happy to be corrected by this in the ‘know’

Cheers all

It won't make any difference to operating if you go two seperate, split both, single to somewhere then split, the pressure is all the same, so free choice from that point.

I'd favour two banjo on mc then straight run to caliper twice as simplest, least joints, extra kit etc.

Think you can only come straight out of caliper with pipe as that's conditional on sealing the taper at bottom of hole. That's as opposed to using a banjo that seals on the casting face.

My last way of doing this was single braided line down to the splitter box in the bottom yoke and 2 braided lines from there direct to the caliper. This did away with the rigid line altogether. These were made by Goodridge back in the 70s. Due to them not using stainless steel fittings in that era they rusted badly when in storage so they aren’t really reusable. This time I went to HEL as I’ve used them before and there service is great, slightly different setup this time, still single braided line from mc to bottom yoke, then 2 braided to the hard lines and hard lines into the caliper. Explain to whoever makes them that you want an extra bottom line due to the twin calipers and that should solve you having to measure anything as the lengths are well known by now.

I’ve done the same as Ken, but my only gripe was not being able to find a ready made grommet holder for the solid line on The RHS. But I’m using the standard front guard.

Interesting chaps, cheers.

I have taken the metal brake line holder holder off a knackered mudgard half that I scut off a damaged one in the states ready for this and brought home and had it welded on the OS of the mudguard so for all intense and purposes it looks like it's off a twin disc bike with matching line holders in symetry. Just drilled the weld out and had it 'snotted' on' via the medium of a particularly clapped out mig welder  by a pal.
So after what you guys are saying, get a pair of hard lines and come off them to the master or the splitter depending on how the mood takes me?

I'm going to have to invest in new ones as I dont have any at all and would prefer new bits....it s the brakes after all and seems silly to scrimp on the stoppers when the rest of the bike has had this much work done!

Thanls fpr the replies chaps, any piccies woud be appreciated just so its in my head as a mental image, yer know? But only if you've time. 

Got the holy grail in the post this morning all the way form Germany at record speed too. :o......................4 weeks! Two days from Germany to the UK and the rest of the time languishing in the post office sorting orrifice in London apparently!................The UK, great arent we? ;D

check that bad boy out....................Piccie to follow, (crap laptop and its on me phone ;))

whoop whoop, the last (apart from the brake lines) sought after part for the build. Just waiting on sending bits off to get them Cemachromed up in Wigan and then paint n seat and thats it for spends hopefully. S another 600 quid then Roo?? DOH! ;D ;D

Surprisingly the rear shoes were brand new so saved a bit there.........they were the only new bits on it, so they've gone back in. ;D ;D...........still winning..a bit ;D

I had a right faff trying to get the rear wheel in and it just wouldn't fit! there wasnt enough room between the rear end of the swing arm to get both tentioners in and the hub!!  HUGE SWEARFEST!
 After getting a hub from here, a brake plate from there, new rims and spokes I had that 'cold sweat' start thinking it was going tp be an expensive cock up but on pondering over half a packet of digestives and a brew, followed by a good shot of insulin ::) I looked at the rear of the bike and noticed that the swing arm was, what appeared to be twisted, or so I thought. As it turned out, all is fine except the NS plate part  that the chain tensioner goes on and that the spindle goes through was twisted inwards at the bottom. I can only presume its had a knock or been dropped at the powder coaters and I hadnt noticed. It came off the bke OK and unless you were looking for it you'd never know so I bobbed it on and admired the shiney!.

The fix was, and dont roll your eyes it worked like a bloody charm, was to put a piece of 3"x1" on either side of the arm on the inward faces and wind it apart again with pressure from a scissor jack..........and a few taps with a plastic mallet! it all checks out and everything is parallel so Im happy with the bodge, I mean fix.

Anyway, first time success and a sigh of relief, albeit a sketchy bodge. When in Rome and all that! ;)
 Once the chain link is found and I can get it on the bike I can get the back end buttoned up and ready to get it off the ramp and the viffer on for some surgery. It was out by nearly a strong eighth 3/16th's (for the younger crew, about 3 n a bit mm). Squeaky bum moment averted and moved onto other stuff like the brake MC and bar associated gubbins but things are moving on.........which is nice :)
