The Lockwood catalog is very useful with this. there are exploded diagrams of all the 912/914 parts with part lists and applications. Page 56 of their 07-08 catalog shows that the piston for 912S is 888 381 and the piston for 912 and 914 is 996 549. The 912 (80 bhp) came first, then the 914 with the same innerds, followed by the 912S (100 bhp). According to this catalog the 912 and 914 heads are the same, and the 912S head is different. Simiiarily the barrels. If I was doing what you suggested I would buy the 912 for all the parts and use the 914 block (I mean crankcase). Whether there would be any value in the old-914-parts built 912 I don't know ! There are a number of things that wouldn't come with the new 912 - such as the double ganged oil pump. I suspect that buying a whole engine might well be cheaper than buying the individual parts, as the parts are mighty expensive ! But it might be best not to let your supplier know what you intended to do ! Here in the UK I understand that such rebuilding may not be permitted, but in the land of the free - you are free :-) HTH Richard Holder ________________________________ Message 3 _____________________________________ Time: 05:50:29 AM PST US From: Catz631@aol.com Subject: Re: RotaxEngines-List: Silicone for Spark Plug Threads Thom, Roger is right on the money ! The instructor Dean at Lockwood said pretty much the identical thing . I too have been using Champion anti seize for over 35 years on all my Cont/Lycs but this is a heat transfer paste not an anti seize (although it is that too) Rotax specifies its use on the 900 series and it is cheap .Us "old farts" can still learn to change our ideas from time to time.

Also crankcase fretting, there are seals on the hold down studs and they get worn. Then oil goes up the studs and out at the base of the cylinder. New engines have sealant round the base of the cylinders, which seems a bit like an afterthought!

I am sure there are better sites onto which to install the sensor, but I was hoping to get agreement from similar owners to fit it on the downward coolant line running back from the reservoir on top to the radiator directly below. I have not read the specific instructions as yet, but am fearful of disturbing a complex area immediately behind the reservoir because of its tight component population. Is it workable to take temps from the vertical coolant line?

Go to Year #7, Q1 2008, page 1 for pics and words on the installation of my coolant temperature sensor. I believe that this is where the factory recommends installing the sensor. I'm sure that anywhere along the line from the coolant manifold down to the radiator will do if you prefer not to disassemble all the plumbing and other assorted hardware on the upper aft of the engine. Do remember that you may have to work on this thing again at some point in the future. Back behind the engine on the vertical line may be a difficult location to access.

I have been criticized for doing the lower torque but I do it for two reasons. 1. I pull my plugs a lot... I never really trust the EGTs to do more than give me a trend. Plugs will always tell the whole story. 2. I feel the 20 in. Lb. will create less stretching of the heads. I've been torquing plugs into outboard engines, snowmobiles etc.. for more years than I like to think about and I've yet to strip a thread.. I've also yet to lose a plug from having it too loose. The important thing is consistency. You can only get that if you use a torque wrench or for the real small stuff a torque meter.

Ferg The sensor MUST be at the hottest common point in the system and this must be just after the header tank (which receives the coolant from each cylinder head on top of the engine) and before the radiator intake. Which I think is the same place that you are proposing.
