I was very satisfied with my 39mm Kehein FCRs - they performed well on a stock 1188 to a 1380 and 1314.  ...but you'll be amazed with the horsepower gain from the 1349 with bigger carbs or a well sorted FI setup. 

Any advice on cams from the crowd here?

Frank

Yes, be very, very careful if the bike is for road use. It's very easy to stuff up the FJ's (or any engine for that matter) great useability with the wrong cams.

meh.... Fuel Injection from a Yamaha XJR1300....Go on, you know you want to.

Hey Klav, IIRC Steve looked into the XJR fuel injection and it would not fit on the FJ. The throttle body assembly has the Throttle Position Sensor (TPS) on the outside left side of the assembly. This unit fit fine on the XJR which used a center backbone frame, but it would not fit on the FJ with the perimeter frame. The TPS would not clear the left side frame rail, that's why Steve and Marc came up the 'Busa throttle bodies on a custom intake manifold.

I wonder how's Steve doing? I wonder if he still has Thor?

Yes, those TMR's should be used with UniPods and not open velocity stacks...

Naw, we have already talked about it. The FI from the XJR uses a dual throttle plate system and the secondary plate acts as a governor. There might be some options down the road as aftermarket parts become available, but at this point many disgruntled XJR owners regarding FI.

Oooh, the frame rails are in the way,that's the problem, eh?
Hmmm, you know how magazine test riders reports often say "The FI was as smooth as well set up carbs blah blah blah'?
There's a lot to like about carbs.
There's a lot to like about FI too.
Biggest advantages  found personally with FI bikes over carbs are ease of starting, no problems with altitude and fuel economy.
(That's a cultural difference too, ever notice how many Americans go on and on about MPG?)
So your ZX1200 carbs have the same 'Spacing"
Would that also apply to the later models FI rails and throttle bodies?
If so,there's a lot of parts out there.
I'll keep my eye out for such things, post the links here.
This will be an interesting build to follow, well done that man Flynt.*

I'm on the same page...  A very mild street/strip grind is what I'm thinking.  The Yoshimura ST-1 cams are also interesting, but maybe hard to get.  Fun searching for now.

Thinking through the other mods and cleanup a bit more now.  I will straighten and repair frame, anodize some bits, add some electrical system flexibility and robustness, maybe go to a CDI ignition...  What else should be done at this point?

[Klavdy]

Stealth install laser jammers and radar detectors?

[Flynt]

Winter projects are fun!  Only downside is no FJ for the next couple of months...

So last night she got stripped down a bit...

and Boats.net got a preliminary order.  Now to get the frame repairs and powder coating underway...

Frank, I had posted this before, use the following code: 'meetsister'  and get a additional 10% off your order

For whatever reason this reminds me of when my wife and I were in Tijuana many years ago.  Right in front of my wife, a guy asks me: "hey meeester, want to meet my seeester?" 

Just had to laugh, still makes me smile...

And now the skeleton has been delivered to Frameman for a tuneup.  3-4 weeks turnaround predicted...  so Randy, we're in no rush.

Time to decide on some cosmetic details.  Thinking of blacking out frame, swingarm, USD fork uppers, ...  essentially anything that is bare Al and I'd do the grab handles and Renntec bars I have the same.  The engine should really get highlighted by this treatment and it may make the bike look newer (not really a goal).

Other options abound, so I'm looking for suggestions.

Frank

[Klavdy]

Wow, this is really going to be some bike, huh.
Pretty much the ultimate FJ.
Well done.

[Flynt]

Found/purchased Keihin FCR carbs with pod adaptors...  I was told they are the last FJ kit in the US, so now they are backorder from Japan only.  Should have them late next week or early the next week.  Also found a local tuner with dyno locally that has parts and experience to help me dial her in once I get it all back together and running. 

Thinking of adding a mappable ignition, but all I am finding is the multiple fixed map Dyna 2000...  are their other truly programmable advance ignition controllers out there?  Do I even need to go that far or will one of the Dyna maps suffice?

Frank

PS - right now I'm back to "stock" cosmetics (meaning keep it looking like a stock FJ with Rittner's mods...  a cleaner version of the bike at 2011 WCR)...  repaint frame, re-assemble, ride.   

[Pat Conlon]

All the new versions of the Dyna 2000's are PC programable for custom timing maps. http://www.dynaonline.com/skins/products/sportbikes/dyna_2000/

But with a big hairy balls motor....right?

SHIT YES...  1350 with big valves, port/polish, and all the go Randy can muster   

Thanks for the update on Dyna...

So Frameman called with some bad news...  the frame and the triple tree are pretty badly bent, lower triple not even repairable.  Swingarm bent a bit too.  The good news is I found a new lower triple and Pat's straightening the rest, so I can get her straight again...  money and time. 

Klavdy - lucky you were not as beat up as this bike was from the "cone incident".  Amazing how much damage I've run into that was not obvious (lesson learned for me).

Frank

[Klavdy]

Bummer,now I feel bad about selling it to you.
Apart from scratched up fairings and dinged forks etc,the deeper damage that was done was not obvious to me, the bike never got stripped down before I went back to Aus, it just sat in the garage over there.
Never even took the fairings etc off.
If I'd known it was jacked like that there would have been no way that it would be sold as a whole bike.
Would have stripped the parts off and called it  a day.
Maybe Randy has some good frames?

I was there that fateful day, K-Man's bike after it went down, had about 300+ feet of asphalt to scrub off some speed and still hit the hill side and bent the front up badly. K-Man had his gear and did his own slide/tumble on the asphalt. Happy you walked away with minor injuries. I still have the pics from that day somewhere around here.
