    Posted: 06 Sep 2017 at 09:00

Time to start this thread. Below a cunning plan plus acquired items and to be acquired items:

Plan:
Gen1 engine with Griff’s 1060 kit + Gen2 heads & Gen2 TBs + Edwards airbox with OEM paper filter. JS Performance hoses. The cherry on the cake is TSS slipper clutch. By the way, has anyone got one for sale?

The engine is a 70 tkm Gen1 engine from 2002 Mille. It will be taken apart and checked for wear and tear. For this reason I ask if anyone has good condition Gen1 engine spares in case I need them. I guess it is mainly gearbox related but con rod bearings and such can come to question.


Once the heads and barrels are out the barrels will be shipped to Apriliaperformance and the disassembling of the lower end continues. Hopefully all is good there so that the engine, equipped with TSS slipper clutch now, is ready for the new 1060 barrels and pistons once they come.


After that the tinkering to mate the Gen2 heads to the engine continues. Hopefully the engine is in the frame in January/ February so that that the TB can be mounted and I guess there was a way to use the original idle tuning with the Gen2 TB.


March time could be starting the engine and getting it to a dyno room for 1-2 hours.

Slotted cam sprockets 189,31 € (AF1)

TOT: 1 970,08 €


Questions will be asked and if you have parts related to this project for sale, please offer them to me in an affordable manner

Finally, the target is 140 hp on the rearwheel. How hard could it be?

Edit: Comparison graph from the standard engine taken out from the frame. Not same engine that was tuned. Only performance modification is 2-2 Akra.

The idle adjust / cold start mech swaps over from gen1 to gen2 throttle bodies

Fit gen2 conrods they are stronger

Are you going slotted cam sprockets ? 106/109?

Smaltmoto have tss for 629 euros

Timing will be checked before the decision to slot the cams. Kämna Ducati has also TSS at roughly the same price.

I will stick to Gen1 rods as the change to Gen2 would apparently include some hassle with lubrication of the big end. Additionally the Gen1 rods seem to be good for 200+ hp as the local Gen1 Turbuono has showed.

Disassembly could commence in mid/ late October.
As for the TB I have a question. The "choke" can be set on the Gen2 TB but did that one have the idle adjusting knob on the right hand side of the engine?

about 30 mins work tops to swap the mech. over
 
take a look at some pics in this thread...but once you have the 57's and 51's in front of you it will all become clear

Does anyone have pictures of the weld jobs how they have mated the Gen2 downpipes with the Gen1 2-2 Akra?
 
Is there enough length to make the Gen2 downpipe round so that you do not need to modify the Akra system?

I spoke to Griff about this very briefly a while back.

He mentioned about getting some flanges made up and I presumed for this purpose, as I'm wanting to run a Gen 1 Arrow system, on a Gen 2 1060 motor I've got (going in a Gen 1).

I'll be speaking to him hopefully in the next few days, so I'll make a note to ask him about it again buddy.

If not I'll just be cutting some Gen 2 headers and welding those in.

I've been using Flickr since PhotoBucket pulled the plug. But make sure your settings on there are set to private, if you use it, or people can look through all your pics.  PB ruined the whole thread about my bike. It would be easier to start another thread than try to replace everything Ouch

Better and easier still, You don't need an account with image hosters, you can post direct from your pc on here.

If you click on the white arrow, 2nd from the right at the top, when making a post or replying to one, it takes you to the full reply editor -you will see a little green tree on the top row, 4th from the right. Click on that to upload any photo's direct from your pc. You might have to reduce some in size, as I think the maximum size is 2mb Thumbs Up

JMH, I've just remembered, you need to be a premium member to post from your pc (I think).

I think it's only about 5 quid. It gives you access to the online manuals as well.

If not, I can only say Flickr, as that's the only one I've used other than Photo*ucket.

Engine dropped to the builder today. Dissasembly will commence 21.10.
I'll be there.
 
By the way, do you know if Griff has slotted cam gears?
 
Secondly, if/ when the Gen2 heads need straightening how much can be afforded?

no he hasn't got the slotted cam wheels.

Sure there is a thread by Micah or amaurai on af1 regarding skimming the heads

I knew that but remembered that the price was higher than what it is. $100 plus postage when I give my old ones in return (well, I have three sets anyway at the moment).
 
Next to this mate of mine doing the engine job with me lives a guy with a shop and he does pretty much what he wants so my mate will ask him about the gears at the same time he asks about straightening the heads.
 
That would be the place to do the exhaust as well as it looks to me it is best to have the engine in place for that job.

Yes I remember it was a lot of money ( not necessarily expensive?). If you have 3 sets just slot all and sell 2 of them, I'm sure there's members out there who needs a set.

Information needed on Gen2 correct valve spring length:

The measurement on the used head gives vs. [manual]

Inner: 39 mm vs. [40,9 mm]
Outer: 42 mm vs. [43,4 mm]

Is the spec in the manual correct, the manufacturing done on Monday or what is going on? New springs would set me off ~500 €. Would need 16 of them.

Does aynone have an insight?

It appears the wear limits for the Gen1 valve springs are the same so maybe they would fit, or?

Update on valve springs. The measured ones are going in. Advice from Micah/ Gabro received so good to go regarding that. Then...
 
The barrels are on their way to Griff at Aprilia Performance UK and I'll have a small update post to do with pics. Before I have the time to do this I would have a question(s).

The conrod bolt tightening instructions can be found in the old manual, which I have. It says to use new bolts every time. The engine will be split to check the gearbox so that it does not sh*t itself with more power on the tap so at the same time the big end bearings could be checked as well.

OK, have you engine builders done this every time (they are ~30 €/ each)?
Is it a normal procedure to check them in a build like this in Rotax engines? After all, the engine is 70 tkm. The crank bearings and such will be left alone.

As said the barrels are out and on the way to Griff. The old ones looked good as new after 70 tkm.



This conversion has been covered here before but the pictures are gone due to Photobucket shafting us. So, about the heads.

The camshaft position sensor Gen1 vs. Gen2 in the front cylinder

Inside the valve cover vs. outside the valve cover
Exhaust cam gear vs. intake cam gear
Pin inside the gear vs. pin outside the gear

As the sensor is inside you need the Gen1 valve cover as it has a slot for it. Additionally, the camshaft support in Gen1 has threads for the sensor and the Gen2 one has only holes. So you need threads made in it. There is an X mark between the two holes in the support.

The Gen2 head makes contact with the valve cover so some machining is needed to take material out. The exact amount is known when the heads come from the shop. Additionally, a slot needs to be machined so that the cam sensor wiring can be taken out the same way as in Gen1 heads. For the rear cylinder both Gen1 & Gen2 covers go.

As for slotting the cam gears we have decided to slot the Gen1 gears for the front cylinder and the Gen2 gears for the rear cylinder. This is because of the pin location in the gear. No need to take it out then.





Piston ring end cap was a question but Griff at Aprilia Performance is able to hone this as our final build spec was given to him. The piston pin offset is no worry. The OEM pistons have a 1mm offset to the rear of the engine but the kit pistons are symmetrical.

Some small worries as well. As the clutch was taken out it was seen that the one of the end plates on the springs behind the outer basket was cracked. Everything was still there, though. I have another used set of those springs and end plates so it is a matter of putting together the tightest package I can get out of those.

Oh... and the divot pins were pretty tight in the heads and in the cylinder and some of them in the heads got a bit mullered so I ordered new ones. 8 pcs.

I guess, this is it for now. More in November when we take the next push.
