My Streetfighter project has officially kicked off. Initially all 3 FJ's will be involved with engine and head swaps.  :scratch_one-s_head:
Casper has the damaged engine that needs repaired and rebuilt. That engine will end up in the Streetfighter.  The 1297cc engine has been removed and the head is off. The head from the 1995 has the fresh rebuild with oversize valves. That head will be removed and installed on the 1297cc engine, which will then be put into Casper. The stock head that was pulled from the 1297cc engine will go on the 1995 engine.   :wacko1: :wacko2:

Parts have been ordered have have already started to be delivered.

Which one gets the "Turbo Encabulator"?
The glass is not half full, it was engineered with a 2X safety factor.

Lots of burned oil on those pistons...Now would be a perfect time to fix those leaky oil rings or throw those POS Hank Scott pistons away....

I noticed that too, Father Pat knows of what he speaks.  Pat, as I recall didn't you have a similar problem with rings that didn't seat?  Now would be the time to address the issue since it's out of the bike and apart.

I have the same problem with my 1350. Oil consumption. From day one and Still. Until I get some of my other projects done it will have to stay that way. At least it will always have fresh oil. Lol

Looking good Fred!! Have fun!

Yes, it was a hard lesson for me ($$$)
The tension on the Hank Scott piston oil ring was too light and thus allowing oil to be pulled up into the combustion chamber during closed throttle deceleration.
A brand new engine burning 1 quart of oil every 800 miles was unacceptable.
The Hank Scott Pro Lite short skirt pistons might be fine for racing, but they (literally) suck on the street.

My current 83mm Ross pistons work great.....
Dan, Ross makes a 82mm you can use, Fred, Ross makes a 80.5mm piston you can use.

A bit more progress. Removal of the rear subframe. I never realized how heavy it was. Waiting on the new rear subframe hoop and other parts to continue. Cleaned up the new wheel a bit.

Awesome to see this project going! 

Can't wait to see your version of a fightered FJ.  Are those cigar boxes you are using for parts organization?!

Great to stuff Fred, an excellent collection of desirable bits to work with and nice to see you in a secure garage with not one, but two lift tables and what appears to be a well kitted out workshop and three FJ builds on the go....FJ heaven! After being dealt a few bad hands in recent times you deserve this.

Unlike restorations, Streetfighter's are a product of the imagination, it'll be interesting to see what yours can come up with.  As you know, Stuart Monk has one on the go as well at the moment.

We've had fighters brought to the forum before but I don't believe we've had a live build, keep the progress reports rolling.

The cam chain caught my eye, why don't you drop it into the case when you remove the cams so it's out of the way for the duration?

Wiating on engine parts... hopefully they will show up tomorrow..

A small bit of work on the Streetfighter today.. The auxiliary lights came in and mocked up. The Blue Angel Eyes will be tied to the low beam and the White light will be tied to the High Beam.

Today was head swap day. Removal of the oversize valve head that is on the 1995 FJ, too be used on the 1300 engine. Head gaskets and other parts arrived from RPM. The removal was a breeze with no hiccups. The install of the stock head from the stolen bike was just as easy. I absolutely love the YAMAHA timing mark system. TDC with the rotor and get the cam dots lined up with the #3 cam caps and everything is set. Checked valve clearances and only 3 valves needed adjusting.

When the stolen FJ was recovered, the exhaust mid pipe and RPM muffler were missing. I was informed that RPM has a couple of spare mufflers and mid pipes. The new mid pipe and muffler arrived with the head gaskets. I really didn't want to contact Hindle directly for a mid pipe and muffler. I did confirm that the 'Y' pipe can be flipped over and a left side exhaust can be done.  :rofl2:  :yahoo: But this will mean that I will have to buy the head pipes / Y pipe from Hindle and a custom fabricated mid pipe will need to be made by a local muffler shop for the high mount muffler.

The LED headlight bulbs came in for the Streetfighter dual pod light. Photos are of the Halogen low beam and LED low beam. The last photo is with the LED high beam and Auxiliary main lights.
