Yeah mig or tig always looks dreadful compared to nice gas welds, but as long as it is relatively smooth inside.

The mid section looks about 60mm long, but that isn't really relevant. Pipe's tuned length is a constant once revs are decided by ex timing, the shape & volume are merely a by-product of the angle & length of the cones. Multi section diffusers often employ some reasonable angles which makes pipes get big quickly, but shallower cones take up more length. That header looks long, but only because one is used to seeing them curved I suspect.

Ummm, wellllll, , yeah.

Just put the new fork seals in tonight, only $15/pr or so from Seal Imports down Penrose. I've put the same 20W oil in but have altered the amount. In the beginning I put in the correct amount leaving a 112mm airgap but it dived too much so I added some preload on the emulators plus about 30mL of oil. I thought it may have been too much and restricted travel a bit, so this time I have gone for a 75mm air gap which was surprisingly little extra oil over standard.

The engine has developed a fairly decent gearbox oil leak. I stripped the cover off and cleaned the gasket and mating surfaces with electro clean and reassembled with a good gasket plus a smear of Hi-Temp Red. It was good for weeks but has started leaking again, badly. I haven't used it so I'm at a loss for the cause, unless Jane has been going for sneaky rides

Time for another strip and clean and try some Loctite gasket goo.

It's gonna need more than "some" gasket goo. Strangely it is close to exactly the same failure I've had with another cover on a different set of cases. I'm down to my last cover, an MB50 one with the tacho drive. I need to find out what the cause is and a remedy.

Couple of pics of the pipe as well. I'm visiting Morgan Engineering this morning to sort out a few pieces and should be able to finish it this weekend. It ain't pretty but I do have a list of excuses.

I know what the probelm is
It's that infield sweeper at Mt Welly
you know the one
you keep taking a close look at it

If you don't wind your head in I'll take you along for a close look as well next time. Ask F5, I've done it before.

you wouldn't be the first
but first you have to catch me

Why don't you just cast your own cover? Why you're at it you may as well convert to a dry clutch too

He's not kidding, Mike is a passionate racer & if taking you out means hurting himself considerably more than you he'll do it for the principle, even if he's forgotten what it might have been. Took us both out of contention for the F4 GP at Ohakune ( was it a paid 'hit'??

), though I did ride the F5 with aid of a lot of ice in my boot.

My bike still got 2nd in the GP, and I heard you couldn't get your ankle back into "your" boot so borrowed someone else's larger boot to pack the fat ankle and some ice into. Could be wrong but it seemed like a good story.
Olly getting admitted to Wanganui base hospital when he came to get me the next day was a bit of a laugh as well. He couldn't drive after they attended to his right leg but my right leg was OK so I ended up driving.

The new pipe is on. It isn't quite finished in the photos but you can get the idea of what I've done. I think it's pretty well crash-proof. Having it all underneath is going to allow a very tidy rear end.
