MNZ proposed rule changes

[sidecar bob]

don't worry, there are 4 cable ties securing the "pantry bike".

and its been load tested.

Well if it doesn't collapse with that fat cunt on it nothing short of controlled demoliton will see it fall down

...here's me thinking 'the poor cunt can't afford a shed', but it's the inside seating you can't afford ...silly me...

Two things come to mind there...

La dolce vita - Tauranga style....and "you're too drunk, bro, spend the night here".....

Yep, and when you look at Canadian pre 82 equivalent rules, Mags have to be solid spoke - no hollow spoke allowed which rules out most if not all the modern 17's - and sends you looking for Dymags...Our rules look pretty good compared to a lot of others.

Its probably the point you are making, but banning cheap & accesible second hand hollow spoke 17's sends everyone running for a set of exotic wheels worh about 4k a pair, if you have a spare set for wets thats 8k which is 2k less than the entire 371 bike owes me.
If I had to spend 8k on wheels Id take up another hobby that I could afford.
Having said that, some of tha Aussie teams were taking 5 engines worth 50k each to race meetings before they put a lid on that.

I heard from a very reliable source that they (TZ750's) now cost about $60 to $70 a lap to run, most of us aren't up for that as a good 4 stroke would be a fraction of that. I'm sure malcy25 can confirm if this is the case.

Aye, the numbers are BIG. In 2001 when we got the first of the up to 3 in the garage that we were running we calculated 20 dollars a mile. $35 a lap at Puke.....

That was fuel, oil, pads, chains, tyres, pistons, rings, cranks rebuilds, seals. No entry fees, cylinder replate jobs or other damage.....

I haven't bothered to recalculate it now, but with piston life in the 500km range and 4 of them and cranks rebuilds in the 1000km-1300km range, things multiply out to a large number pretty quick! The good news is that the parts are available aftermarket, but mostly better made than original.

But, the first pull of the throttle makes it worth it (I can see why druggies get hooked if it's half as good as a big 4 cylinder two stroke hooking gears!) .....but you do get a little selective of when/how often you get them out.

The false(!) stroke boys probably do get a far easier time on the $/mile as while the parts may not be much different price wise, the service life mileages will be better and they are easier to ride on the limit than the big TZ. Wheel base and torque curve are in favour of the deisels for your average rider.

BUT being realistic, the really fast 4 stroke riders will be chewing parts too. Going fast is not cheap, whatever you ride.

I think it's a bit of a myth than one - yes, if you got those guys to build you an engine, it was 20-25k cause I know a guy who asked the question! But the are more interested in investing their own time in their own engines. The actual parts costs if you ignored their own personal time, they are not a massive build price - they see it as fun, so happy to invest their own hours. And they had lots of engines from their 25 years of drag racing the things.

Time + parts + enthusiasm + skill = low cost motor in their world. Of which they had most of those elements already. Different story if you are outside looking in however 9and had to pay their time).....like most of their competition!

I thought I was paying up when a wheel set cost me a little less than $1k for some jap dymags (ie wreckers OEM fitment 17's)!

Thats $NZ2743 for the rear & $NZ1925 for the front for a total of $4668 for a pair including GST & I havent even included freight, Times two if you want a wet set & you have the best part of $9500 landed, so yeah, I was a bit off with my guess of 8K for a set of Four.

Reminds me of the Dallas Rankine story - new set of marchesini's, wrong colour. Off to the powder coaters to strip and recoat..
He hadn't heard for a week or so, rang up, to be told, oops, we dissolved them...Somewhere over 2 grand in the early 90's.
