[SBK Project: 2v Motor - 748/996 era Frame]

[junior varsity]

^^^ Really?!?  6mm exhaust studs?  I'll have to disagree on that fact.  ALL 2V engines 1990 - 2008 are 8mm.  I know.  I have the following here in my shop right now and they're all 8mm:

2006 M620
2004 SS1000DS engine (in a monster frame now)
1995 M900
1999 M750

The old-school nuts were 13mm to remove, but you can get the 10mm 'new style' nuts to go right on there.  I put the 10mm nuts on the 1999 M750 last week BTW.

Odd. I'm grabbing some calipers and will post up later today. The Commonwealth online parts finder named the part number I searched for (2002 SS 900 exhaust stud) as a M6x65.

Weird.

Also, I'm going to change the thread title to something more relevant shortly. I will also post pictures of the saddest clutch I've ever seen. If you can out-do me, I'll be impressed.

Lastly, I can't find a source for a M10x1.0 grub/set screw. I want to remove oil pressure sender there - this is to be a barebones track toy.

There's a M10x1.0 plug that goes into the exhaust headers on the 2V Duc's.  It's available seperately but I don't know what it costs...

[junior varsity]

Oh, I didn't even realize that was the same thread. I will grab one off this SS's headers and see how that works.

It'll work just fine.  I've done that same mod on the current project bike...

[junior varsity]

I remember seeing it on Darryl's M859 (kopfjager), but it was a special Ti grub screw.

I must be wrong then (wouldn't be the first time)  but I'd trust both Stu and Speeddog's extensive experience over mine most any day.

Regardless, it sounds like a cool project. Best of luck with it and please post pics of your progress.

[junior varsity]

I've got some really good local minds to pick as well as you guys. Some motor pics will come up shortly.

I'm going to pull of alt side case cover this afternoon likely to see if its really worth messing with. If its all rusty in there, we may just sell of anything on the motor that's reasonable and junk the rest. or keep it as a learning tool.

[Duck-Stew]

The 4V engines are 6mm IIRC....

[junior varsity]

Per your recs, I removed all exhaust studs. Piece of cake.

Took off valve inspection covers, expecting to see something ugly. A little gunk here or there, but... zero rust. Everything looks fantastic inside on the top end... Starting to get curious about the underside...


Pulled the heads expecting to see something horrific on either the cylinder or the valves. Nada. Some carbon. Can turn cam pulleys and make magic happen without much issue. Other than having ugly cam pulleys, the heads look great. Again, I delay the pictures, but I was happily surprised.

Question: Best place to get tool(s) for:
  a) Retorquing heads when I'm done. I fear the Ducati tool is not cheap (for a U-shaped 15mm wrench). By "when I'm done", I mean when its been ported, has perf. cams and possible other fanciness done to it.
  b) Tool for holding cam, and tool for removing cam nut? I'm looking forward to using the VeeTwo cam pulleys which don't have a fancy nut. or perhaps, a fancier nut that does not require a tool, depending on how you look at it.

So next up is the alt case cover and clutch case cover to see if bad news lurks behind. (I have an alt-case cover removal tool, no worries here.)

I should note that I got this engine for about $400.  Including swingarm (only one axle plate), injectors, oil cooler, rear brake master, and clutch slave. I consider myself quite the bargain shopper, however I thought that gremlins would lurk inside given the price.

[junior varsity]

Oh, and the calipers said 8mm today. Somebody should update the Commoto online parts finder number. And its not a symmetrical rod - the head side is shorter by a good bit than the flange side.

G'day a m.

Better get those cam pulleys quick if it hasn't got adjustable ones. 
A mate of mine just bought some and said that Vee two were throwing them out real cheap.

I reckon the 900ie cams are good, nearly as 'long' as the ST2s and 'better' than the 900 carb cams..

I can see your thinking. That bike would go well with 41 FCRs on short manifolds, porting and Ignitek set up. You could fund some of that selling off the throttle bodies, etc. It will be a great project to watch. I'm envious as I'm selling the race bike to pay for the kids dental work.

Here's a contingency plan in case you run out of cash and can't finish the project. You have spares to upgrade and support your Monster. You could fit the ie cams to your bike (they are a little 'hotter'), you could use the primary gears as I think Ducati swapped to the 32/59 'hunting tooth' ratio of 1.84.1 and get them lightened. You have a spare close ratio gear box and bottom end parts. The flywheel pick ups and alternator are different and would sell. There are parts to sell off to pay for the swap over. You have parts to sell, parts for spares and parts to retrofit. Just have to check on what's interchangable and what isn't.

It's good to have a back up plan.

Either way for $400-00 you're on a winner.

[junior varsity]

That's what I was thinking.

When I first started contemplating the end of VeeTwo parts, I got a spare set of adjustable pulleys, so we are good there. I also have a set of their track grind games (-212), and torque (-210) cams, so the IE cams may end up getting sold as well. I know they are hotter, but not as hot as either of the two sets I have sitting on the shelf currently.

My local shop, AMS has a full set of STM pulleys on the cheap, so I might look into those if they replace the center pulleys as well (and not just the cam-end pulleys).

This motor may end up being a parts house, or get some use in a frame I acquire. I'm going to see if Stuart (Rust) has a spare supersport frame in his garage, and if so, I'll start looking at triples and forks, and have a rolling chassis before I can blink.

I'd really like a 2V superbike, but I'm just not sure how to make it work with my level of expertise.

This is getting really interesting now, there will be three simultaneous 2v sbk builds on the forum.  I can put you in touch with the guy that machined my 900 to sbk width if you like.  I'm doing a 748/916/996/998 and Theo is doing a 749/999 so I think the only logical thing you can do is get a 848/1098/1198 frame. 

[junior varsity]

Hahahaha. Yes, and get some MotoGP-esque bodywork, no?

For machining the cases, this required completely stripping them down, splitting them and removing everything? Ballpark me a price. Round to the nearest hundred, please - no need for you to find out to the nearest dollar what it cost.

Anything else needed to be done to the cases? Or, at that point, are you capable of bolting everything together and having a rolling chassis?

My other two thoughts or alternatives:
a) Pierobon F042 frame (expensive) - I'd have the first carb'd F042 style bike to date. However, it requires its own tank, which makes it less appealing.

b) Supersport done up in the Emozione style bodywork from Kaenma. At least I'd be unique in Texas. Or so I'd hope.

I'm also going to pick Jeff Nash's brain up at AMS since he worked on the Troll Supertwin project.
