My take on the belt(o-ring) style 90° porting tool.

**wobbly** · 6th December 2016, 18:29

Rich - shame I couldnt have been at Taupo to see the 2Ts kick arse, but I was ( am ) flat out on Dennis's new one.
A friend saw your crash, and told me you were not a well boy with a broken pelvis.
Shit man thats a major, so a heart felt " get well soon " from me.
The bikes an easy fix, a pelvis break aint.
WTF happened.

Adegnes, I do like your videos, but Rum? Perhaps a little E85 might do the trick.

Adegnes you might find it less cumbersome on smaller cylinders if you you a flexidrive on the dremel hung from a hook.
Or you could make a flexidrive out of the old speedo cable.
i also seen these, they seem cheap enough.
Slightly more ergonomic as well. Not as coll as making your own of course.
thi =s would also be better driven from a flexdrive.

Cheers Wob. Apparently there was all sort of theories on my injuries. I have a couple of small stable fractures in my upper back and thats about it. I will fine. Even today i am moving more freely. It was a very fast and brutal crash. Over the bars at around 140 /150 kpm. I can tell you now if you want to save some weight on Dennis's bike you can run a single 320 rotor. Enough power to flip the bike. We have all switched to single rotor calliper setup. I have not seen the bike properly yet its still in the trailer. I will post a before and after pic at some point.

Good ideas!
I've been playing with the idea of a thin/flexible/strong enough flex cable that could be connected directly to the porting head.
Don't know if such a thing exists.

I am using twin small 255mm discs, the wet setup from Aoyamas 250GP title bike, be interested to see what a 320mm and caliper weight is.
The rotational inertia would be greater I would imagine, but the race 1098 one piece calipers are heavy as - just cant afford the smaller 250GP versions.

Back of the envelope calc would suggest that the 255mm disks will have a advantage with a lower MOI than the single disk but the single disk setup will have less un-sprung weight.

I'm genuinely impressed with the performance of the single disk, my only concern is over heating it at Wanganui races....

Anyway, here's a wank shot of the NSR300 doing it's thing onto the front straight of Taupo, by far the best i've ever had it running!

I ran a single 320mm rotor on an FZR 750 race bike. It ate the disk, but it took three meetings at Manfeild before that. I shouldnt think you'll have an issue on the 250 at all.

Very Sorry to hear you have suffered a few injuries, get well soon. But glad to hear the bikes are going well, I expect the bent one will straiten up Ok, I have a spare MC21 frame and swing arm, yours if you need it.

Cheers Rob. I was put off racing for a day or so. Now I just want to pull the bike out of the trailer and start fixing it. I also have a spare frame and swinger. Thanks for the offer. It might be baby steps going racing again. I will work on getting the 50 sorted first.

**F5 Dave** · 7th December 2016, 17:31

Yeah don't make decisions in haste.
There's always the 50. You can't possibly hurt yerself on that.

It turns out generic multi tools stuff is pretty cheap
