fj1200 turbo "thug"

[Dan Filetti]

I am following this build with interest.  At first, I must admit, it seemed as if you would never actually get the thing running under it's own power, for anyone of a thousand reasons that stymie ground up garage builders attempting such an ambitious effort.  

However, it's looking more and more as if I maybe wrong.  From where I sit, it now seems as if your stick-to-it-iveness may well get this project up and running; kudos.

That said, I was wondering about the steel trellis frames that are so often used on chopper-build projects.  I know it's been done successfully for many years, and Ducati uses this approach to great effect, as another example.  Yet, when I look at this thing,  it sure seems like there's not enough there to keep that motor from twisting itself out of that frame under hard acceleration/ deceleration. Also, how will the weight of the bike not flex that frame laterally given the considerable inertia and gyroscopic forces at play while riding, especially in a corner?  I suppose you have taken these questions, and others like them, into mind?

It's the visceral physics that usually kills or injures the experimental types, seems to me.

Just wondering.

Thanks for your interest, yeah I know a lot of people who doubt me with projects but as with previous bike restos. I've allways succeeded.
The whole idea was to make the project difficult, scary and to show what you really can do with scrap yard parts. Shiney isn't everything haha.
The frame is HEAVY! im sure it will be ok for this application due to being so heavy guage. If I have space for some braces after all the pipework I may weld a few in for good measure. It's not a sports bike so I doubt it will undergo as much forces as their frames do, but they consentrate on structural rigidity and saving weight. Weight doesn't come into my list of issues. It takes 4 lads to lift it!
I will do whatever it takes to make it work.
At the mkment I'm looking for a 12v oil pump so I can run a completely seperate oil system for the turbo.
I think this is a more suitable idea.
I need a different cdi now as mine was the wrong one and is now fried.
I'll get a video up when i get it running then once its running properly its going to my friendly bike garage where I'm having all the brake and clutch lines done properly.

got my smaller jubilee clips through the post today for my 10mm fuel lines
cheers ebay!!


still looking for a sensible place to mount my coke can sized fuel pump! may mount it by the battery box but need to keep the fuel pressure regulator as close to the carbs as possible for accurate fuel pressures.
going for a malpassi petrol king with boost fuel advance.

will eventually mount some ghetto boiler pressure gauges infront of the handlebar mounts on the tank i think.

might need to put that on a bit better as its touching the frame, need to slice a couple mm of the silicone hoses
got to link up the pipes off the plenum to pressurise the float bowls and the top of the diaframs.
need to steal some more rubber hose before i get round to that and find 2, 2-into-1 T's to link the 4 float bowl overflows to the 2 plenum connections...



i'm not going to bother with a choke as the rack is easily pulled by finger when sitting on the bike.

here's a picture of my old rat bike, this thing was fun!


wish i could have those wheels on the fj...

[backstreetheros]

and a couple other bikes i've had over the years...
always been more of a car man but got a secret obsession with bikes...


when one Husqvarna WR400 2 stroke isnt enought.... buy two!!


little chicken chaser CR125


Wanted something with a bit of tourque so got the KLR600... this was useless off road but very impressive inbuilt decompression valve
you wouldnt kick it over without it!!

[backstreetheros]

Well the bike has been on the back burner for a while as my business is keeping me well occupied at the moment,
Had a half hour with the bike this afternoon and put on some more jubilee clips from the carbs to the engine, tricky as they foul the throttle if you dont put them in the right place, also rem
oved my shortened ammo box as going to need to come up with a
smaller box seeing as i have to mount the fuel pump, oil pump, oil tank and possibly oil cooler in this space aswell as a battery
It's all turning into quite a squeeze even on a bike as big as this!
My oil pump which is 12 lpm brass and stainless should be plenty man enoygh
Going to drill out the banjo bolts on the turbo for better oil flow.
I will try get some more pictures up when I get a chance.
Will be purchasing a dynotek 2000 ignition for the bike soon too.
Does anyone make a sandwich plate for the oil filter so I can run 2 oil coolers for the engine and one for turbo?
Or is there somewhere I can tap the block?
I'm no fj1200 expert unfortunately!

[backstreetheros]

Been still very busy so not had time to do alot. Got a chance yesterday to make a bracket for the oil tank and mount that. Incase you were wondering the tank is a vintage warmwell copper hot water bottle and the bracket is a cage of 22mm copper pipe and fittings. The cap from the hot water bottle made a small but cool oil filler cap. Got the oil drain from the turbo done too. My oil pump and oil cooler arrived. The pump is a seaflo brass gear driven pump and the oil cooler is from  a 1998 subaru impreza. Im going to mount the numberplate onthe side like every other chop. But i am going to mount the oil cooler behind it with a gap so air can still circulate yet its not such an eye sore.
Dynatek ignition.
Finish the oil lines
Fill it up witg fluids
some form of switch plate to control all the pumps.
fuel pressure regulator and fuel pipes
then it should run! Getting excited now.
I will be sure to film the first start attempt for you lot
Pictures soon

So this evening i thougjt id come up with an idea for more cooling...
Thats untill i stumbled upon rpm racing...
They make all the parts i have been dreamkng about!!
Fj-aftermarket oil adapters.
Fj to spin on oil filter! Which i could probably get a sandwich plate on too...
Oil galley plug with tapping for oil temp or pressure!
The only thing i cant find is the two blanking plates on the front of the lower forks... Mine are missing...
Has anyone purchased from them who also live in england?
Is postage reasonable?
I am so excited to make my order!!!
So happy aomeone makes all the parts i need!!!
If you havnt already... Check them out... Legends!

[backstreetheros]

couple of pictures...

thought i'd get a bit creative with some copper pipe


made the oil tank and bracket and done the return from the turbo
yet to get the welder out again and do the oil pump brackets and oil cooler brackets...
will get on it soon.


will get some more pictures up soon but lost the cable from my phone to my laptop... which is also the cable for my digital camera!

How heavy will this beast be mate

[backstreetheros]

Extremely!! Once its on the road ill take it to the bridge and see what it weighs.
Got myself a mocal spin on oil cooler sandwich plate and some hoses yestedday and today i sprayed an old helmrt i had . Got carried away and went to halfords to get clear laquer and came out with a 14AH Bosch battery for the bike.lools like im goimg to have to moumt that ammo box after all because yhe battery fits perfect. Will have to get the ignition controller in this box too!
More pictures soon.
i can lift the front wheel of this bike off the floor on my own... But it is heavy...

[FJmonkey]

Fixed it for you.

[fj11.5]

I think a standard Fj weighs about 250kg wet   ( oil/ fuel ) ,
