The engine is out - but whats this bit

[bikerzx7r1981]

Hi all,

thanks for the advice, got the shaft bolts undone. I finally got the engine out with a fair bit of pursuation.

I have been swapping parts over from the old engine to the new. but am not sure what this is:-http://s740.photobucket.com/albums/xx42/kevlid1981/engine%20bit/

please see old/ new

I know the old one was the oil pipes fittted for the oil cooler, but the new one doesn't look the same... does this mean it's not oil cooled?

Thanks for everyones help, and questions I'm happy to keep updating this with photos of resto if people are interested... I can certainly do with the guidance .. so if people want me to I''m happy to do it.

Here's your pics. Sorry, I'm not educated enough to answer your question.

Oil cooler

Well, yeah, your 'new' engine came out of a bike that didn't have an oil cooler (as an accessory), but I coudn't tell you if that coupling from your old engine will fit on your new one. Personally, unless the bike is going to be ridden in a hot climate (not bloody likely)or is going to be ridden hard or raced, I'd just ditch the one that's on your bike now.

So does that mean the new engine (GS1100G) was air cooled?

Not much hot weather in the Uk, but plenty of traffic james :-).. Just wonder what the implications could be ?

Would like to use the oile cooler if poss?

They are all air cooled. The oil cooler is an addition to compliment the air cooling.

If you want to use it, then put it on the motor you're putting in the bike.

You do need to add the oil cooler and lines before firing up the motor

I'd ditch the cooler for use in the UK, the GS engines have plenty of cooling as is. If you want to treat the engine extra nice get some synthetic oil (for diesel engines preferably). The synthetic oil will not thin out as much as dino oil so it will protect on those rare occasions like when you get stuck in traffic on a hot day.

Oil cooler function

The oil cooler is not there to cool the engine, it's primary job is too cool the oil and keep it from degrading. I had one of those on my old Toyota GTS and oil stay brown all the time, between normal and regular oil change. It is a good addition and help to ensure a long life to your engine.
My advice would be try to fix it,the part show in picture is the adapter to plug the in and out hoses from the cooler. Unscrew it from old motor and unscrew the similar part on the other, clean old gasket and screw old adapter with new gasket on the good engine. Reconnect the hoses.

Good luck.

My 1000S has an oil temp gauge and the oil doesn't get above 200F until the bike is on the road for about 20 miles. The oil needs to get about 212F in order to boil off condensation, so keeping the oil temp as low as possible can do more harm than good, particularly in a place like England where it rarely gets hot.

one assumes evaporation also occurs and at much lower temps than the boiling point of water.

oil coolers drop temps at the sump and prevent over heating.
any inline four japanes bikes I have seen get their oil form the sump pumped through the valve train to cool the hottest parts of the engine.

I suppose the cooler is a must for high rpm extended use in climes where the cooling fins cannot adequately sink the heat away.

oct in new england vs summer in the mojave desert as twere.

I rode in UK for close to 20 years, You wont need the oil cooler mate, I rode a GS550, 850 and 1000 all through "our" lovely rainy summers, and even in hot weather "75*" anyway, you can split lanes there, so just keep moving and you'll have no issues.
If your stuck in one of those famous 42 mile tailbacks!!!! sit there if you can't move and turn the motor off!

Cooler is added complication you don't need & the lines look ugly too.....

I'm also from England... (London).

I've run a 1000G through the desert here in CA/NV in temps upwards of 100f at 80mph for 130 miles or so at a time (stopping for gas) on quite a few occasions.
