What engines will fit 1990 FZR1000?

akcribs · Post by **akcribs** » Fri Aug 22, 2003 5:48 am

I have a 1990 FZR1000. (Frame plate says "Manufactured in 1989".) What other 1000+ engines will work on this frame without major surgery? Thanks in advance.

why would you change? There is no engine with any significant power increase available. the yzf1000r thunderace can surely be fitted but you will gain very little from it. r-1 will not fit if thats what you were thinking.

OK. Well, what other year FZR1000 engines will work? 1989-1995?

All 89-95 motors will fit. All connections are the same. I have just installed a 94 1000 (1040 bore kit) motor in my 90' fzr 1000 frame, no issues. Almost ready to fire it up. <img src=http://www.ezboard.com/images/emoticons/smile.gif ALT=":)"> Not sure of later model thunderace or R1 motors but you may try searching the past posts for the answer. I think someone brought this up previously. Edited by: <A HREF=http://pub28.ezboard.com/bexupbrotherho ... >jjs777</A> at: 8/27/03 8:47 pm

Biker, Are you sure of what you are saying. Other seem to disagree. Have you actually installed an 87 or 88 engine into a 89-95 FZR? Have you see it done or just heard rumors? I don't want to go out and spend a lot of money and shipping cost on an engine that doesn't fit properly. I prefer not to modify motor mounts and such if I can just buy the right engine. Please provide some proof or explanation of your statements. This is no place to joke. Many of us are seeking help with real problems. So if you can provide some real help it would be greatly appreciated.

akcribs just take a look at bikerz posts and you will understand that he does not know a flying @#%$ about these engines. All 89-95 fzr 1000 exup engines are the same but those from 87 and 88 bikes will not fit your bike. do not buy one of those. they have different cylinder angle and even your exhaust pipe wont fit the older engine. as someone (chuch D i think) said, try buying one of 94-95 models as they have stronger gearbox and are of the most developed (hearsay, dont know for shure). my 95 engine works fine in yzf750 frame, although i thought that it had blown in middle of summer... lucky it was just carburator and a minor electrical fault. good luck in motor-hunting

All years 89-95 use same block and top end, however, you must convert oil pan if using 91+ in 89-90 set-up. The 89-90 uses an oil cooler and 91+ uses full liquid system. Many optios, just thought you guys out there should know. Also, there are part # supersessions within the Yamaha system that translate into better flaw, fixed parts. CHUCK D.

ChuckD - Can you elaborate on your remarks about oil pan conversion and full liquid system? I just swapped out the engine from my 90 frame and swapped in a 94 motor. I had no issues installing everything back up. What have I done wrong?

bikerbo do you think that you should learn to read?<img src=http://www.ezboard.com/images/emoticons/happy.gif ALT=":D"> cos you shure can´t write either

ChuckD · Post by **ChuckD** » Mon Sep 08, 2003 4:52 pm

Like I said before you twit, 89-95 will work. You can't put it in a 87-88 frame without major and most likely ill affects. Next you'll be telling us that you put an R1 engine in a 87 FZR frame. Don't dare and use me in your quest for stupidity. Any more you gotta say, I'm waiting. Fool, you silly, silly fool. CHUCK D.

Chuck? My question still stands as far as 94 motor swap to a 90 frame where you pointed out several issues. Thanks. Must I resort to posts that barely rezsimbull english for you to respond? Whatever it takes I value your knowledge. Sew tck these chucnkiedeez and ......oh this hurts pretending to not be able to spell. whewww! ouch!

ChuckD · Post by **ChuckD** » Tue Sep 09, 2003 11:33 pm

The 91+ uses full liquid radiator cooling, the 89 uses an oil cooler. You have to change the oil pan and I believe the oil pump and sending tube. When both are upside down in front of you, it all makes sense. Besides that, there are no more mods needed. CHUCK D.

Like Chuck said, the older bikes had a "radiator" type oil cooler and the "RU" onwards? had a water to oil sandwhich plate that fits betweeen the crankcase and the filter. When I changed my 1989 exup to the later type engine I also used the later type water radiator so I could keep the new type sump and oil cooler arangement. PS the thunderace has a bigger capacity water to oil cooler and with the exup engines dismal oil pressure it is worth using if you can get hold of one.

the bad english poster left after chuckd dismissed him with a few 'twit' comments etc lol Hey Mark you said you did the 89 bike to the newer motor conversion and you mentioned the oil/water cooler gizmo sandwich between the block and the filter, my question is did you ever grasp what chuckd had stated about you have to change the pump etc ? where he also stated it all makes sense when your looking at it? I too took a 94 motor and stuffed it in my 90 frame and all I did was remove the sandwich plate and stick a spin on oil filter in place - I did not change sumps or anything But that has me very concerned that maybe I am missing something ?

As far as I can remember the old type engine had an oil take off on the sump for the air to oil type cooler as well as different oil pump and oil piping within the engine. If you are running an RU motor with original sump and no sandwhich plate you have no oil cooling at all <img src=http://www.ezboard.com/images/emoticons/eek.gif ALT=":eek"> What happened to your original oil cooler and all the pipes that came with it? Mark

Post by **jjs777** » Fri Apr 23, 2004 12:14 am

What happened to your original oil cooler and all the pipes that came with it? I removed the original 90 motor from the 90 fzr1000. I then purchased a 1040 motor that I was told was a 94 engine. I didn;t pull anything apart when I installed it. It had the same oil coolinh bosses in the case as my 1990. So I bolted everything back up the same way - using the stock 90 oil pipes that lead to the self contained oil cooler. For comparison sake I looked closely at my 1995 fzr1000 and it retains the bossings (is that a word?) in the case as the 1990 engine but they are obviously not drilled out or used. Which leads me to two possible assumptions. The 1040 motor I bought is really not a 1994 and is in fact a pre 91 since it has the bosses for oil cooler - OR it is a 91-95 motor and the shop I got it from simply drilled out and tapped the oil bossings to allow the old style oil cooler to mount. What do they call it ? Occams Razor ? All things being equal the simpler explanation is to be prefeerred ? I probably ended up with NOT a 94 motor but a pre 91. I'm gonna record the case stamp on the supposed 94 and see if anyone can trace it for me as to what DOM it is.

I'm 99% sure that the old type engines that had a radiator style oil cooler did not come with a spin on oil filter but the old fashioned cartridge type, what one has you engine got? Also there is a lot more than just some extra drilling to get the old style cooler to work on a newer engine including oil pump and a load of little pipes in the sump to plumb it all in. I assume it's all working OK? Mark

Post by **jjs777** » Fri Apr 23, 2004 5:43 pm

Thanks for the reply... The 1040 motor aka the supposed 94 motor has a spin on oil filter (not the typical 90 catridge style)....but when I received it it did not have the sandwich plate at the oil filter mount that a 91-95 motor would have to allow the oil to flow into the radiator portion of the oil cooling system. Yep agreed on the lots of plumbing stuff inside the motor besides just bosses in the sides. I look at the riva yamaha parts fiche and compare as closely as I could the difference between the oil pan/sump between the 90 and 95 motor. I now see somewhat what chuckd had mentioned quite some time ago about htings being different. So I guess this leaves with having to find out what year the 1040 motor actually is. The other thing I want to do is pull off the side aka 90 style oil tubes and see if there is pressure on one side...otherwise the other poster is right in stating that I may not have any oil cooling at all.
