 I think the JMC swingarm on the GS was the source of all your problems.

Loved that arm, an early steel concentric.

I hope you got my sarcasm. I have a JMC on one of my bikes. After the 2 year wait to get it, paying for polish but getting it in the raw, modifications to get it to work etc etc I guess I'm happy.
JMC are gone but not forgotten (for the wrong reasons). My understanding is another company bought there jigs, blueprints etc and will be making them again with the emphasis on customer service.

Completely got it dude, I am well aware of the legendary F****p that was JMC customer relations. Oddly enough I only had positive experiences , a few years ago they did a drag slot extension by return of post, 'Lucky B*****d' was the typical response..

Ive a couple of braced JMC swingarms too,but they wouldnt fit in with the chop builds here.

sorry for my delayed response on this one...
been high demand at work as usual on the run up to christmas so havnt got anywhere with either bikes.
the GSXR750 will be a ringer as i already have the logbook for the donor bike and the engine numbers match.
the fj may have to go for an SVA but i don't know how that tallys in with not running any lights.
i don't want lights on either bike as wouldnt ride them at night anyway.
if the issue gets too bad with sva that will be a ringer too. i don't know how kindly the tester will take to my turbo or side exit?!
i think there will be a few interesting conversations with the law over the fjt anyway seeing as its so in your face and different.
just hope i can outrun them with straight line kookaloo speed!! haha. 

the police around here are not too bad as i live out in the countryside. if your being an arse they will be an arse.

i've done absolutely nothing to the fjt in a while, i've bought a load of wire and connectors and ignitions and things so i can do the wiring loom properly when i get a minute to my self.
trying to find another sprinter van to join the fleet and another plumber employ but its proving to be quite difficult!!
i'll try get on and do some more work on the bike soon.
thanks for your interest and i really appreciate everyones comments and feedback on the bike.

my misses has started naming the bikes "rusty" and "not rusty" haha.

Did I see the gsxr HUC for sale on an auction site? Ive been bored with mine for months,but once all the Christmas stuff is over,I shall be starting work on things again. I need to make some money for other projects. My AMA superbike/endurance styled FJ1200.

Merry Christmas.

[backstreetheros]

well spotted!.
its back on there again due to a time waster.
as much as i love the bike i need another van more than i need it
and its making me lose track of my fj!
i will get back on track with the fj and get all the wiring loom done when i clear some space getting rid of the gsxr
i still need to find for the fj...
anti-dive blocking plates, or anti-dive units to fit there (just so i can put oil in!)
a banjo bolt to connect my clutch hose to the master cylinder
a load of wire and alot of spare time...
does anyone have a wiring diagram for the alternator kicking around? i assume the two wires coming from it are live and sensor live? (both connected to battery?)
i'll get on with it soon!

on the upside... i did get a blacked out visor for my Craft RX1 Cobra and a set of carbon encrusted fox gloves from santa clause

updates soon...

[backstreetheros]

right with the GSXR sold i no longer need to worry about it...
time to get back involved and finish this project.
i've managed to get the banjo bolt i was so desperatly searching for for the clutch slave cylinder.
i've taken the bike back out of storage to get on and complete the wiring loom.
got all the bits for it too.
starting my motorcycle licence on saturday as i am going to need it fairly soon.

i've let slip a little with this project but have recently realised how much i want to get it completed.
i'll get some more pictures to upload as all this text gets a bit boring after a while!..

Good on you for keeping after it!  My ability to work on my projects comes and goes all the time    Think I'm on the 5th year with the dragbike...

Hi Backstreet.

How bout a few new pics?

[backstreetheros]

I have actually booked a day tomorrow to do my bik!!e
Thats how bad its got!
I will get some pictures tomorrow!

[Havoc]

Excellent, me too, looking forward to the photos

made a little bit of progress, although i got all my tools out only to have a call out at 8.30 AM for a broken boiler fan motor! inconsiderate!
on my way back i decided to stop in the local farm store and see if they had any clips i could use to hold my plenum on a bit better.
i found some silicone hose (not cheap) which was of suitable (if not a bit small) size to get the fit really tight.


i cut these in half to make 4 shorter peices, then as they were so tough i soaked them in boiling water for a while to soften them up a bit,


it took me about 10 minutes per hose to get them onto the plenum as so damn tight. after that i wrestled with the plenum to get it attached to the carbs.
took bloody ages to get it on there as such a tight fit but it is finally on! and airtight!
i replaced the shitty yellow hose i used to pressurize the float bowls with some black over-braid fuel pipe.
i also bought a load of new 3/8 inch fuel pipe to fit the pump.


the fuel pump is mounted there temporarily as its the only place i could bolt down that shitty bracket (im yet to find a decent way to mount a fuel pump)...
with the fuel pump installed i set to work doing the wiring.

the ammo box i used is quite large but is a surprisingly tight fit to get all the electrics and components in there!
i wired the starter solenoid so it is in the bottom of this box,
the dyna 2000 ignition module is in this box too.
i wired the retard trigger wire to the normally open switch i had made from wizards of NOS which i previously fitted in the boost pipe to the plenum.
i fitted an ignition key in the front of the box as its a bit safer than just a switch ignition. there is also plenty of space here for an ignition light and some switches.



the bike now seems to act a bit more sensibly in the top half of the revs, ive set the retard trigger quite low and set the igniton to 12 degrees retard and it seems to spool up nice,  yet to turn the rev limiter up off 9000 yet though...
spits a nice foot long flame when you drop the throttle.

it idles like a bag of shit but i guess thats because its now jetted completely wrong for the plenum and turbo and that.

few teething problems at the moment...
1 the overflow tapping in the bottom of the tank i now am using for a return from my malpassi petrol king fuel pressure regulator spews petrol towards the top of the tank and leaks out from around the filler cap fitting.

2 my nice shiney new clutch slave cylinder is no longer nice and shiney as it spewed oil out from the casing when the engine reached oil pressure... i guess this is just an O ring??

3 i need to find out where the idle adjust screw is on these carbs as it wont idle (or does very badly)

4 my gear linkage from the forward controls is shit, its too flimsy and needs replacing.

i'll get more pictures tomorrow as i ran out of light today due to some very cold customers.

[backstreetheros]

here's where the petrol is escaping from the tank, obviously i'm not going to paint over it.


heres the boost pressure switch that controls the ignition retard under boost.


sorry about the shit pictures its dark... i'll try get some more tomorrow.
