I do know that he'd planned to do it's first season as a senior production bike.

After the carbs, I got roped in. The cams were just sitting there and everything followed. Methanol and about 170HP.

I'm aware of a set of RS40's I could probably source from a mate in Welly.
It did cross my mind more than once over the weekend, but nah, it's a street bike.
Anyway, today the rear link & swingarm bearings were washed in petrol, blown out & re assembled with fresh grease & installed today.
Spring removed & shock cleaned up, lubed & put together.
Main target was motor out & back in on the same day, which was achieved, everything else is just tinkering.

Is that some AMP forks up there?

Didn't lose any bolts, cleaned the spooge out of the front sprocket area, speedo still works, lubed the clutch cable which now has a delightfully light pull, switch block still sending correct signals, no bolts lost, no resorting to yoghurt and/or super glue to bodge repairs.

Everybody goes too big on those motors. First year, Kirby won at Teretonga with bored 750 carbs - 33's. Lapped about 63 seconds and won by a mile.
Next year with Holden riding, we pulled out the 38's and he tried them in practise. Said, nah, the 36's are better so we went back to what we'd been using, RS36's.
Won by half a lap - and was first to go under 1 minute lap. Kirb had gearing charts worked out. it was geared for 185mph at 11000rpm.
Holden reported that on the first two laps when he was going for it, he ran it into the rev limiter just before getting on the picks for the sweeper.

OK, so, I have no fucking clue what THIS is, but pretty sure it isnt part of the oil pickup.... I'm throwing it out to the ideas group as to what it is. if anybody recognises it I would be grateful. It is alooooominum (magnet no stick) and it looks like half of something.

Also most of the valves are tight - the manual specifies for inlets 0.11 to 0.15. I have 0.10 and plus 0.05 so was looking for a nice loose 0.10 for the inlets. The exhaust is specified at 0.18 to 0.22 so I was looking for 0.2 (which I have....).

So, we have exhausts at around 0.1 through 0.15 and one of the 8 is at .2

The inlets are a loose-ish 0.1, some toight loike a toiger 0.1's (noted on Cyl 2 as "tight AF") and some loose 0.1's.

The motor spins freely (when checking the valve clearances).

The oil was lovely. No little sparkles in the sump (I dropped it)

The coolant (that not-water red stuff) was OK too - no oil obviously.

Oh and today I learned that while it looks like there is enough room to drop the sump off the motor with the front exhausts in place.... yeah nah, there isnt.

Also one of the fucking exhaust studs came out with the nut still on it. FFFFUUUUUUU.

So, what's the consenus? drop the motor out and whip the heads off? (that means I can turn it upside down and see up its skirts too (oooh errr).

TBH I am not that keen on rebuilding it, but if I do I want more capacity. Someone on this site famously said something to the effect that only a dickhead rebuilds a motor with the same power.
