fzr400 exup

Sooooo... This FZR400 gently bleeding all over the garage floor. Assuming I have to remove the engine and potentially replace it....

Um.... would a FZR 600 engine fit? and if so - where would a boy get one?

YAMAHA FZR400 Group in Yahoo there all nutters in there lol and yes it fits the thundercat front end fits on too !!!
http://autos.groups.yahoo.com/group/FZR400/
but from memory you need he 600 headers/pipe too its a wicked upgrade
i was going to do it on my 1TJ but never got round to it ..

from yahoo group

Installing a yzf600r engine is a shitload of work. Requires removing metal
from the shock mount and frame to clear the oil pan (or change oil pans),
bending the yzf exhaust to clear the rear brake (or remove the rear
brakes!), using yzf600 carbs with either pods and rejetting, or with fzr4
airbox without rubber seals, using some other radiator (fzr6 is direct bolt
on, but not as big, F3 is ok, yzf6 has all 5 in/out ports to match the
engine but is difficult to mount), probably need to swap the harness, and
the yzf electrics require some cutting and wiring and custom fitting. But
the fzr4 battery is bigger, so should work fine.

Listers have said the fzr6 engine is a direct bolt in, as are the computer,
reg/rect, radiator and exhaust, and uses same harness. I forget about the
airbox. Easy swap, and with a pipe it makes as much power as a stock yzf6.

AFAIK the 600 and 400 frame are same. Heard of a few FZR750/400 projects and even the odd exup thou being thrown in there.

nodrog has a 400 engine under his momma's house apparently...

OK - research phase is nearly completed and I'm pretty sure I know whats likely to be wrong. Either way the head is coming off and looking at the bike I think I should do that on the bench because it will give me a chance to fix a few of the other items. Also I'll drop the exhaust and check the exup valve (or ditch it)

I'll need a paddock stand to do that as the side stand connects to the steel subframe - any suggestions on a suitable stand for an 88 FZR?

Serious answer

I'd love that but the real aim of this project is a little closer to home. I want to sort this bike out properly - learn a bit more in the process and pass it on to a deserving (and hopefully RICH) new owner. Given my current work load that might take a while...

How much? Send me a PM.... Jeeze mate - how would I know - I've never owned a bike that needs anything so daft as a pit stand thingy - bloody stupid modern rubbish..
