is the yamaha FJR1300 engine any good
A mate of mine at work has written off his FRJ 1300 which he had had chipped to 185bhp. the insurance company has returned the bike as part payment
for the storage charges. the bike had faring and front fork damage only, so i was wondering if this engine would make a good swap into my mk.
what do you think of these engines?
what are they worth?

It would seem that he may be an old fisherman at heart (the one that got away and all that)
he said that it was a shaft drive engine, would that make it any better for the BEC application?

Do a search, i'm sure MK have fitted one in an Indy, It will be harder to fit in the engine bay cos the engine will be east/west rather than
north/south like most becs, so lining up the shaft may be a problem.

I was thinking of it in the future. currently i have a vulcan engineering 2.1 pinto in the engine bay with 165bhp spec.
think that will be good enough for now?
i'm already wanting more power and it's not even SVA'd yet.. may be bike throttle bodied and megasquirt??

I'm using the same engine - it is ideal for a LHD car, but would be a difficult package for RHD.
Seems like a good engine, with 150hp and torque close to the hayabusa.
I took off the cover from the shaft drive, and it would be possible to remove the right angle drive, and make up a driveshaft flange adapter, then
mount it like the R1. In fact it is like a overgrown R1, and shares many parts.

Hi Rob
out of interest is the right angle drive 1:1 ?

No its actually geared slightly higher, with the end result of a 5th gear ratio of 0.929
(as far as I have been told). I think it works in my favour (3.46 diff ratio)
You can see the difference in size of the bevel gears in the picture in my archive.

GSX1400, big-ass muscle bike tuned for arm wrenching torque rather than top end power.
FJR1300, bloody quick hyper-tourer in the same line as the 'busa. 185bhp would be quite 'special' and i'd worry about engine
life but I don't see why it couldn't be done.

Dear Ditch,
The FJR engine is very suitable for a BEC.
My car (MK Indy) is ready and is on it's way to the SVA.
However, I'm curious about the chipping you're mate has done. Do you have any details?
Brg, El Frodo

Can you please tell me what differential you are using with your FJR 1300?
Thanks!

Hi Steve,
I'm using a 3.42 from a Toyota, although I don't have it running yet. I remember calculating it at the time as being a reasonable ratio. I
can send the numbers if you are interested.
(But you know you want to sell me that engine of yours!!!  )

Nope, I want to use it in a car of my own creation. :p sorry.....
and I recall that the lower the ratio the better it will run. A 3.42 should be adequate. What is that, about 140Mph top speed at 10K rpm with a
13" wheel?
