FJ1300 with a European Twist

[giantkiller]

Looks good Fred. Who is making the stickers for you... Debating whether to make fj 1380t or just leave it FJ1200t. If I can get Turbo pistons for the 1380 block.

Hi Dan,

The same person who did yours.... Jeff0308 in Australia

That's what I thought. He does a great job. I had mine clear coated. The stock ones were clear coated on the 86. Don't know if they all are. He used some different material than he was using. To make sure it would work for clear coating. Worked great.

Your going to love the extra torque. Kookaloo!!!

[FJ1200W]

Might consider smoothing those sharp edges on the piston crown -



Looking forward to following your progress and hearing the results.

What are your plans for jetting?

I can wait.... patiently.... possibly.....

I had considered doing the jetting myself and I have received some figures on sizing and adjustments. 

After careful consideration and the amount of dollars already spent on this project. I will be sending the carbs out and having them professionally done.

Jason, came over this evening and it took us about an hour and we got the engine removed. Let the teardown begin...

[aviationfred]

I felt motivated and did the teardown....

Fred,

What does the bore look like?  The pistons don't look too bad in the pics.
I realize the lure of the BigBlock you'll be riding soon, but you could probably have refreshed the engine with a set of rings, a hone, and some new valve stem guides. Plus the requisite gaskets, chains, and maybe guides.

In fact, if the bore is clean you may just find someone who wants/needs a  used cylinder and piston set, like the one you're replacing.

But, where's the fun in that?

That's interesting, are all the FJ1200 pistons gas ported?

Didn't have those holes on my '84's pistons.

Possible aftermarket pistons..... I will measure them this evening.


I honestly can't say..... Maybe Randy can weigh in on this question, or George, he re-ringed his engine this time last year.

Gas ported?

Are you referring to the oil "drain" holes under the oil ring?

Randy - RPM

[Pat Conlon]

Oil drains? Ok, yep, I haven't seen those on FJ pistons before

[aviationfred]

I measured the pistons.....

Old pistons-77mm

New Pistons-80.5mm

Both the old and new pistons have the holes
