Cam nuts, some folks have made a crude tool to get 'em on and off.

Old belt and *big* curved-jaw vise grips can hold the pulley.

As long as you don't distort the snap-rings they're OK for re-use.

If your primary gear is held on to the crank by a taper, take it to a shop that has the OEM tool to get it off.
The OEM tool is a drop-dead serious puller, and it's completely necessary.

Are you splitting the cases?

The head nut tool can be had on ebay for ~$20
Wouldn't it be easier to graft on a **9 style oval lower mount than swap cases?

Nice tool for the steering head, but he was talking cylinder head nut and cam nut.

Great thread I'm really lovin it. I used this tool from my local Napa Auto Parts to get the heads off my M620. I used the 9/16ths. It was slightly loose but it was as close as I could get without going metric (which they didn't have in stock). I used it gently so I wouldn't damage the tool or the nut.  I hope this helps.

Edit: I just found some metric ones online.

Very nice tool below Speeddog!!

For the head nut tool you can just weld a socket to a cut off open end wrench.  Keep it at 90 degrees to your torque wrench and torque will be accurate.  I think LT Snyder also sells one.

I tried to gob up a tool for the castle nut and use an old belt for a strap wrench, and that just didn't work although I'm sure someone with better skills could make a better tool.  I got this:

What about those nuts with the bent-up washers? I see two, one on each side of the cases.

Are you splitting the cases?

I was planning on it. I don't know of another way to get crank out. It will need to be balanced (and knife edged and lightened, and hell... made to look like the SPS cranks...) for ze big bore kit. I've read a few threads, one particular with Chris Kelley, talking about the Mahle Pistons (95mm - "966" kit).

I figure, if I am going to do this and take my time (as working budget is slow going, wife has needs), I better do it right. So, balanced crank, go over every bolt and bearing (replace as many bolts as I can with titanium since I'm taking my time), high compression/big bore pistons with the high-temp barrier coating, Carillo rods (just don't know about the longevity of Ti rods, like Pankl - no experience there).

Here's the "plan" at this point, for the motor only:
- "966" (964cc - 68mm stroke, 95mm bore), carillo rods, balanced SPS-style crank job
- VeeTwo -212 "Track/Race" cams and accompanying valves, MBP Collets, VeeTwo billet adj. pulleys
- Ported heads
- Split Keihin's on the short manifolds, Ignitech and DynaCoil ignition
- VeeTwo lightweight primary
- Motogadget for fusebox/wiring & tach/gauges
- Replacing the head studs with APE or if budget allows, Nichols.
- Febur or NCR oversized oil cooler. Or acquire new Hypermotard evo oil cooler (which is large and in charge to begin with)
- 48t slipper clutch
- Going to have to figure out a 2-1 pipe, or possibly one low (horiz), and one under tail (vertical) for equal length (a la Desmosedici race pipe kit)

For the chassis, it'll be going in a 748 frame/swingarm/triples. Alu Mono subframe, some fairing stay, "Race" front fairing (and I'm considering still using the air-ducts to bring air towards the carbs, unobstructed by an oil cooler, and bring cool air towards vertical cylinder), Mono-tail, 748-era tank or ETI fuel-cel, and a 2v "long" bellypan, some form of lightweight wheels (mag, cf, alu)

That's what I've penciled out in the garage. Clearly there are holes in my plan, budgetary concerns, and a steep learning curve. I'll be taking this quite slowly so don't get all "antsy-in-the-pantsy" on me just yet.

I have, however, settled on a name. Or pair of terms to describe the bike:

TESTA AEREA - Air Head (ha, jokes)

and

CIRCUITO PARZIALMENTE NUDO (Track, Partially Nude - since it has some fairings - windscreen/bellypan and the seat is "comprehensive")

A) Have the shop do it.
B) Buy/borrow/steal the sockets and an impact gun.

Your build list looks good.

I already have some of these things. VeeTwo cams/pulleys/lightweight primaries.  The engine was going to get torn apart for inspection anyhow since I don't know its history, and since I want a big bore kit, might as well do the rods and crank while I can.

I think Jeff Nash will do the heads. I've talked with him about expectations from his porting and the 2v heads he's done in the past have been spot on comparable to the dyno graphs that I have seen from MBP heads. Two big differences seem like (a) cost (Nash isn't as expensive), and (b) not painted red. (fine, I want mine black I think).

Oh, and that giant "ball bearing", I've just realized was the shift detent. Ha. I'm sitting there staring at what I've taken off of the motor, and then realized that when I took that out, there would be that ball. duh.

Good thing...

those main bearings are pricey.
