Post-Classic rules on engine swapping

[malcy25]

Yip,That'll be William Birch,Cut up a perfectly good TZ to make that KTM single thingy,Ernie was tho only one out of all those guys to achieve those times on petrol,Oh and William was from Huntly

One of his TZ's is in my garage...another was in the family a long time ago. We had some of the body work which must have come off the KTM. The bottom fairing had a chunky alloy plate glassed into the bottom. Not sure if wasn't there to catch the end of the conrod....

No it was there as a rubbing strip for when the shock broke...which it invariably did...
I was told at the time that the frame was a Ginger built TZ copy not an original TZ.

Bill came south and lived in ChCh for a while. Turned up at a couple of meetings with an RS250. Got blown off by a local with one of Tony's old 400 Kawas and we didn't see him again....

Yea,But they cut up a TZ frame and used the steering head and swingarm pivot

Hope you took the Krober ignition off it then,That thing was bloody fast but was constantly detonating due to the ignition having no retard cycle

Yeah, when we got my bike and another TZ from him 97, he brought them up from Chch one weekend when he was seeing his father in Huntly. The other bike was Ex Pero as well.

Dont you get me started mr Williams!! hahaha where alse they gonna go? the rules have been based around that period.... yes there were a few people running 450s in f3 but that wasnt written in the rule book so call it what ya want. I asked the question if I could change my frame to a frame style what you run with your SV, if you look back that sorta thing was done in the day but not with a zxr and even if I keep the geo to the same spec etc etc it still cant be done so for the weight saving thing no more pies for me but was worth asking about.

In Answer to your questions:
Where else are they gonna go: Ummmmmm, in posties F3 ?, unless of course your confident that the 450's are gonna go out and spank the 600's on a regular basis.......... The other problem with the rule is the actual realistic policing of it. - Stripping engines down to checkover-bores or even slightly over-sized engines that are a feww cc's over the limit, is not realistically going to happen is it ?
Re changing the frame: If you can locate a bimota, rickman, seely, mckiintosh that had your old donkey engine in it - then fine.
Comments on the Geometry etc are irrelevant, - you can change that sorta stuff if you could show some proof (extending swingarms etc)
Weight Saving: Given your obvious love for pies & dohnuts - then donating your limbs to science for replacement of Bionic/Titanium technology is probably the best/easiest solution.......

Ouch man I havent had a Pie for 3 weeks its them damn energy drinks lol also the titanium can be discussed with the surgeon on the 21st
Im agasint the 450 thing for budget reasons.. to many people have built 450s and blow up regularly and then the sport losses thoses people due to lossing intrest in because of the cost that has come with it, and at the moemenet how many 450s run in Posties? If you set the bar for people to run at 450 then chances are we may loose them in a years time and what would that do to the grids we have now?
The idea of changing frames was a half arsed idea and by no means am I aguring the point that you can or cant, Just flicked thru a 2 wheels mag regarding the katana that steve martin rode at PI and looking at the macs chassis, My very limited know of the pre82 I didnt know that, that was as per what you could get in that period, question was asked, question was answered and have not looked at that anymore.
By the way bike build at the moe is ive cut 8 kilos out of it already and 7 off me

BTW - No one can protest the bionic parts, Steve Austin was using them in the 70's :-)

At the end of the day, if you chuck the 450s in F2 then they are disadvantaged against the 600s whereas in F3, the 400s are disadvantaged against the 450s! I can think of only 1 possibly 2 450s in NI Post Classics last year but waaay more 400s. You either disadvantage the majority or the minority.

Of course I'm completely biased as someone who just spent a bundle building a 400 and deliberately DIDN'T rebore or stroke the motor because of these new rules!

What new rules???

[crazy man]

What new rules???

that the f3 bike has to stay a 400 not a 450 in the pre 89 class l take it its what he is saying

Yip,I know what he means,But where are these new rules listed?

Not in the rulebook, Mr Chairman....

It would appear that the proposal put up by NZPCRA has been greeted with such acclamation that no one bothered to put in a remit.

Certainly in the SI CAMS are actively running to the pre 89 F3 regs as far as capacity goes - and trying to police ( politely) the 400cc limit for multis.
It would seem to be an idea whose time has come so someone should get off their arse and do the remit surely.

I think its because it missed the boat last year, hence why NZPCRA and up coming vicclub are running it as a sup reg but I do belive the wheels are in moition
