Someone was after info on that "BLACK SUNSHINE" (http://www.reservoirdogs.ca/blacksunshine.htm) FJ that got built up a few years back.
Check it out, Hot Chicks with FJ, Swamp Donkey with H.D Cruiser thing,,,
(http://www.reservoirdogs.ca/pics/bsbling.JPG)
I remember this bike very well. Belonged to Jon Jarosz I think. I contacted him with a view to buying it when he had it for sale, but some unexpected domestic expenses (less said the better) put pay to the idea.
In some ways it was just as well, as I seem to remember he built the engine without other modification, including retaining the OEM compression ratio, which I believe led to it letting go in a big way later on. I don't know if Jon got around to rebuilding her, anyone know ?
It was eventually parted out.
AFAIK:
1219cc with wiseco pistons
stock crank
stock rods
nitrous in various guises before and after the blower
chromed everything and polished the rest
ported head, good valve job
stock valve sizes i think, don't remember cleanly
blower ran 10psi? I know he tested at that for awhile
jmc swingarm +4" (62" WB)
really ridiculous gearing (16/47 or so)
GSXR1100 front end
Not all gospel, that, though. I was digging through his old netpath postings the other day trying to find the specifics on the bottom end, and this is just what I remember from digging through stuff.

Bob N. has the swingarm and rear wheel (and maybe the front end, too) on his bike, I'm sure he will chime in.
I bought the Supertrapp, never got around to using it, and sold it to Steve C, who installed it on Thor.

Great shame, it was such a looker. I seem to remember her in blue at one time too.

Bob's bike is blue... with the aforementioned parts.
AFAIK, Jon's bike went straight from 1988 White/Silver/Red (as it was featured in Cycle Canada) to black (with a chromed gas tank).

Reason I say so is that I have this pic which I thought was Jon's bike in one incarnation or another.

Yup. I got the extended JMC swingarm and the GSXR1100 front end, including both PM wheels and the front Performance Machine caliper. Jon mounted the PM caliper on the right side to show off the PM wheel. I could never find the matching left caliper so I eventually replaced it with a pair of Harrison Billet-6 brakes. The rear PM caliper leaked, so I'm using a stock FJ brake. I plan to rebuild the PM this year.

The "really ridiculous" 16/47 gearing is now 18/47. It took some getting used to, but now I prefer it. Close-to-legal speeds feel fine, but I can still go quickly if I need to (like when following some silly-fast people in Maine).
I have a copy of Jon's original web site, including the pictures (it reminds me how shiny the bike
could be). If there is a way to host them somewhere I'm happy to zip up the files and send them.
The last time I checked, Jon was riding a Harley. And he's not one to follow a crowd; he rides it because he wants to.

Nah, you're right Barry, that's Jon's bike with the blue sky reflected in that fancy chrome tank.
That's the Cycle Canada article I was talking about.

He has an Electraglide. He's still got a chopper that he built, also.

Any idea what kind of power this bike made?
I ran a roots type 6-71 blower on a street car I had years ago. Running 10 psi boost on a small block mopar I could make about 600 hp at the back wheels. This was with O-ringed heads, solid copper head gaskets, stock (well prepaired) rods and crank and a mild camshaft.
I guess what I'm thinking is that with good fuel, and ign. timing control you can make a lot of power with 10 psi boost. Did this bike run good with the blower or were there a lot of problems?
Thanks
Mark H.
I followed the build on black sunshine when was being built...
had a few niggling issues such as supplying enough fuel for the amount of boost.
But the worst issue Jon had with the bike was when it went BOOM! :biggrin:
sometimes too much is really too much!
he still got some quality kookaloo in before the terminal failure!
KOokaloo!
I am almost certain he told me he had not made any alteration to the standard FJ compression ratio. At 10psi boost I'd say it was entitled to let go !
Actually thinking about it, with 1219cc pistons his compression ratio could have been even greater than standard. He could have been running an effective CR of around 13:1 !
I remember when Jarosz was building this bike. As I recall this was on the old netpath list probably 10 years ago now. Surprised so many remember the bike by name, it's become sort of an FJ legend.

Jon had the bottom end of that engine sitting in his garage for while.
I took it off his hands a couple of years ago and transplanted the APC clutch kit into my "Shadow of Black Sunshine".

The in-line links do not work. I'll fix them when I have a bit more time.
Lovely work.
Reading the article Jon confirms he was running 10.25:1 CR. with 10psi boost and NOS. Without other work IMHO it was always going to end in tears. :scratch_one-s_head:
A thick headgasket and/or base gasket would comfortably solve that.

Certainly wouldn't have hurt Andy. I think APE used to make a set of cylinder studs that would have held the whole lot together a little more 'snuggly' too !
Doug -- sure missed that one, thanks.
Cyl studs would of helped but compression was still way to high. Tried running 10.75:1 in my car motor with ARP cyl. studs, solid copper head gaskets, and o-ringed heads. Could not get head gaskets to hold for long and actually ruined one cyl. block by stressing the crank main journals so much that the main caps would just fall off when you removed the stud nuts - no regester left. Suspect this was from some undetected detonation - caused by the high compression - and yes I was pulling the timing way back under boost and running race gas. Detonation is the killer of boosted motors.
Finally had JE build me a set of custom blower pistons with dished heads and thicker ring lands, compression now was 7.55:1. Actuall pushed the boost up to 18 psi with this setup. Funny thing was that after about 13-14 lbs boost I did not see much increase in power. I suspect this was because the roots type blower was very good at heating the intake charge a great deal at this boost setting (no inner-cooler) and causing detonation issues. Not to mention that super hot air is a lot less dense (less oxygen) than cool air.
Then there is the "blower sneez" blower backfire. Been their done that, bent rods, bent blower rotors, and thats with a pop off valve on the blower manifold.
All in all still would have loved to see Blach Sunshine actuall run down the street with the blower on it. Cool as Hell.

PS - :scratch_one-s_head: not sure how I got off on thst tirade.

I suppose in fairness to Jon he was sorta treading on relatively rarely trodden ground. I run a blown SB Chevy myself. It's a well trodden path really, all the bits are off the shelf. Ya can't say that with an FJ !!
Good hit Jon, you secured your place in FJ folklore :good:
No disrespect to Jon at all! Infact I give him all the Kudos in the world for even traveling down that road. Its not easy or cheap to build a bike like that. Sure can't walk in to your local speed shop and order the parts needed.

Great article...thanks Marsh for posting that. Interestingly I buy a lot of my FJ parts from the same Yamaha dealer, Parkway Yamaha in Collingwood were Jon purchased his in 94. Great guys to deal with, and they know FJ's pretty well.

Nope. Different bikes with Different part #'s. Can it be made to fit? Dunno.
What we do when questions like this come up, is that we go here and look up the Yamaha part #. If they match you got a winner.
