Post-Classic rules on engine swapping

[crazy man]

most of thoses 400s were 96 onwards and running 600 front ends etc etc also I know with the zxrs theres about 25 kilos different between them and 89 zxrs but saying that back then the track was rough... only one line thru thr hairpin you had no choice in that, turn one was a bit like that as well with the slippery cement patch mid corner. its kind of a hard one to pick really bikes where different and a shitty surface (IMO) and today bikes arent the same but the surface is better.
Should put Glen Willams on your 400 Crazy man should be about the same as a Jared Love on a FZR400 and compare times

andy , troy .most of them were on 89 -90 bikes ..600 front ends in the year 2000 were no better than what was on the 400. in facted never sore a 400 with a 600 front end in it. just the odd guy with after market wheels in it like mine and barrys . most guys run stock shocks as well.. that was when men were men lol

What kind of tuning had been done to the motors?

na im sure andys was 96 aye, agree troys was a 89 glen tanners I think was a 89 Hayden was doing 18s on the 89 zxr then when he rode his old mans bike his times droped even more once again mid 94ish I think, Dereks FZR was a early model but once again his times started to drop as he speced his with new parts if memory serves me correctly. I may have to look at some of the old time sheets but im pretty sure there werent that many 89-90 bikes. but your right most of the bikes didnt have them yellow springy things in them that you hate so much

andy wanted to buy my spear bike cause he could not finded a newer one. a 96 bike in 2000-2001 was only a 4 -5 year old bike ! just were not around ! but l had a big cheque book then ...not . the bike l have had no frame numbers because was new frame from japan

[crazy man]

What kind of tuning had been done to the motors?

most the top runners had flat slides all round 66-70 hp . mine had the basic stuff done 13.5 head com, lighten crank, standard pistons with edges rounded to stop cracking , ported head , cdi may of been played with , race exhaust. thats about it

Ok...... ive gone and looked at old time sheets from 2002-2003 nats at manfield... 1st year with carbed 650s andy has listed a "ZXR400'96 Kawasaki" quoted from timing sheets and he did 1.15.905 bruce hansen won with a 1.13.938 and terry fitzgerald 2nd with a 1.15.012 and looking thru the time sheets from 01 hes got his zxr listed as a 96 and seems to be the fastest zxr at every manfeild round followed up by either you or barry armes which was a 93 and from what i can see is the 1st 89 bike is jimbo with a 1.19.623 Im not saying that the time sheets ive got mean anymore or any less then what alse is around or I know best but from what you see comparing todays times with is kinda hard to do due to the bikes ages.

is this old 86-87 fz 750 v4 with 7 valves per clylinder ok for pre 89? http://images.trademe.co.nz/photoser...58524_full.jpg

If I recall rightly, and there is no guarantee of that..... I think the bike Andy B rode at Manfeild in '02-03 might have been Martin Dunns ZXR which was a European bike. Martin spared nothing in building his bikes with as many kit parts and top suspension that he could find. The bike is now sitting in a glass display box in his bar at home!! Along with Andy weighing 25kg soaking wet, it is no surprise he went so fast. Terry Fitzgeralds Suzuki GSXR400 might well have been the most developed GSXR400 in the world back then!?!?!?! But it came at a price in terms of engine life, or lack thereof.
Derek Hill had his 3TJ FZR by 2002-03. He was forever doing something to it. Was always thinking about ways to make it faster. He was never quite able to do the most obvious part, lose his fat guts!! (I think there are plenty of us in that boat!!).
He had full airbox from UK design, FCR's TZ250 wheels, Ohlins shock and front internals but only ever ran original FZR forks.
In my mind, and it is some time ago now, I reckon that in that era (the earlier era bikes of Nathan Spargo and Tony MacMurdo etc were faster for whatever reason) Bill van der Hoven and Dereks bikes were the fastest 400's, Martin, Andy and Terry's were next fastest, but Derek was not the fastest rider mostly due to his extra size over those guys.

Yeah martins bike was a cool kit. totally forgot about his bike, can only find one timesheet with his name it here with me and thats long track vicclub 03 and maybe after that winter series he did nationals with it I think, Jared love on Bills bike was awesome to watch at taupo during tim gibbes winter series was the year beanie set the lap record there of a 39.9 on his GSXR1000 and Jared rocking in on the 400 with a 41.4.
for sure there were some fast 400s back then and then along came them sv

my bike went past Bill van der Hoven like it was standing still but put that more down to his slow corner speed. my bike looks like nothing now days because l'm slow and yet l'm getting more power out of it than l ever had back then

Nitro explains a lot....

If my memory is still good, i seem to recall my kawa 500 doing around the 13's at the WSB meeting. The three top F3's at that meeting were all around that speed - Ernie Cudby's FZR and the guy from Mercer whose name escapes me on the KTM special and Mark Taylor on my Kawa.
Tony was first time out with the new 400 and having problems.
When we came North the only 400 at that time which gave us any trouble was Ernie - and only on Manfield as he didn't travel.
Pete Sales told me later the KTM had nearly worn out his dyno prepping for that meeting - 28% Nitro I was told....
It wasn't enough, Mark outrode him.

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
