General Discussion / Re: When si 1000mm measured like 930mm
« on: Yesterday at 01:15:58 PM »
Its common in the metal game, try to buy a 2mm thick sheet of steel, Verniers say only 1.9mm
1.2 comes in at 1.1 and 1mm comes in at 0.9mm etc

For all the tonnes they sell they can stretch out the number of sheets per tonne by this 'skimming' practice.

Do they have a +/- 0.1 tolerance on sheet metal?

General Discussion / Re: Facebook or Ozvmx Forum?
« on: June 21, 2018, 10:52:11 AM »
The answer is both.

Facebook is when you want to also look at other things.

I do find the OzVMX FB page a bit difficult because adds for things bikes etc take over.  If there could be a separate link for the For Sale section it would be better.

Also love it or hate it people checked the forum out more when there was a bit of controversy.

Maico / Re: Maico 400 Mega 2, whats it worth.
« on: June 12, 2018, 12:05:49 PM »
The bike can not be called original because it was a 250 MX.  Have you still got that motor?  A 490 will always be worth more.  A 250 MX is worth about 5 to 6 thousand so work from there.  Also as the motor is a GS it is also worth less, in my opinion.  The GS has a higher ratio 5th gear and final drive gear.

I only said it's original as there is not any of those horrible billet parts on it. But no the motor is not the original for that frame. No do not have the 250 motor.
The ignition is the only GS part on the bike as it makes for a smoother easier to start motor.

If the motor is a GS the gearing will be different too. The fifth gear that also runs on the shaft that the front sprocket is on is a different ratio.  I know I changed the gearbox on a 490 from a GS to a MX one by changing the Counter Shaft and the two fifth gear, gears.

Competition / Re: Use of leaded fuel
« on: May 08, 2018, 10:04:53 AM »
I was told by a Shell rep not to use what at that time was called Shell Optimax.  I think it is 98 or 99 RON.  Shell themselves said it is not compatible with two stroke oils because it was designed for fuel injected cars.  I always use the 95 Ron fuels in my Maico.

General Discussion / Re: Australia's First Supercross
« on: April 02, 2018, 01:13:51 PM »
This is an interesting question.

Was the Parramatta one a Supercross or a MX under lights.

From a Queensland point of view we have always considered the meeting Blair Sheppard run at Archerfield in 1979 to be the first Supercross.

Blair brought Mike Bell and Rex Staten out from the US also.

It wasn't called a Supercross, it was called Superbowl of Motocross which is the name Mike Goodwin called the first Supercross in 1972.

I even raced at the Archerfield meeting.

Tech Talk / Re: Improvements to lathe
« on: March 28, 2018, 11:09:27 PM »
Just buy some digitial readouts for your lathe.  I think they are about $400.00.  You can also set the readout to read diameter also.  Just like a CNC lathe.

Competition / Re: Not VMX- Anaheim SX
« on: January 11, 2018, 12:30:17 PM »
The AMA don't give the penalties it is a World Champs so the FIM referee does.  My guess is they probably had a word to him.  Just because you don't see or hear about a penalty doesn't mean it was ignored.  Really you can't expect the riders to treat any rider differently.  If a footballer goes into a game carrying an injury the opposition will target that player.

I think also Webb's actions will be noted by fans.  Respect is something that is earned.

Introductions / Re: USD forks and rear disc brake
« on: January 02, 2018, 12:55:09 PM »
Do these items give you an unfair advantage or is it just looks, I was going to put a alloy swingarm  on the TT500 is that forbidden as well, first thing I noticed riding a Suzuki 500 2 stroke was a terrible lack of engine braking, very scary on the first corner cheers

If you are using engine braking to slow you down you are risking head shake.  Big 2 strokes have got engine braking just not as much as a 4 stroke trail bike.  The modern 4 stroke MX bikes haven't got a lot of engine braking too.

Where is the problem?  84 model WP USD forks are legal for pre 85 VMX

https://forum.ozvmx.com/index.php?topic=41488.msg395415#msg395415

I dont know about rear disc but if the 84 model  KTM came factory fitted with rear disc then i would naturally think its legal in pre 85. Check MOMS to be sure.

The 84 model KTMs had TLS drum brakes front and rear standard.  The funny thing is the 83 model had a front disc brake.  To my knowledge the first rear disc brake was the Kawasakis in 1986.
