Class Identification

[Colesy]

Can anyone tell me the correct I.D. and order of lettering for Modified Production Pushrod for a M/C??? Thanks

[ROSS BROWN]

Colsey
Probably need a bit more information in your question.
first : chassis designation
second : engine designation
third : fuel designation if engine is other than production
forth : engine size

by reading your question as it stands

you have a modified chassis with a production pushrod engine.

M PP (engine size)

ps: don't take anything I say as gospel

Ross
Yep that is how I see it M/PP unless someone else has another opinion.
Thanks

Colesy I'm hoping you've seen this page http://www.dlra.org.au/mcycle.htm as it explains it all.
The only thing you don't mention above is if there is any custom bodywork on the bike. This could change it to MPS (Modified Partial Streamlining)

[Colesy]

Yep all good!!! Just making sure it's all squared away.
Thanks

Are you running a modified frame with a production engine-ie standard as the factory made it. Unusual to have a modified frame with a stock engine. Production is as the factory made it, frame and engine

Maybe M/P modified / pushrod or
MPS/P with some streamlining

Is this a Harley/ Buell based bike?

Bones
The frame and engine I am using are as they came from the manufacture (production) and thousands made.
But I am removing lighting, changing handle bars, seating, blah, blah. No cutting/welding, no streamlining and no partial streamlining.
The engine (push rod) will be modified but not a works engine, no turbo, no supercharging and no exotic fuels (just pump gas).
My original thought was M/PP - Modified Production Pushrod.
Your thoughts or anyone else's is appreciated. Thanks

Colsey
I recon it will be M/P xxxxcc
modified / pushrod
cheers Bones

I had this discussion with Gary Baker last year after interpreting the rule book the same way you seem to have.
To run in Production class the bike must look exactly as it left the showroom. Once you go to Modified frame then you can no longer call it production.
So Bones is right, you would run as M/P - Modified Pushrod.

Thanks guys it sounds good to me and one less letter to worry about:-)

Cheers

[DLRA]

Mossy, we are all agreeing, it's just that you've interpreted the letters wrong.
I can't see how it can be anything other than M/PP
production engine class is P
production pushrod engine class is PP

This is a cut and paste of the rules.

Frame type
Designation Frame Class
P___Production
M___Modified
A___Special Construction
MPS_Modified Partial Streamlining
APS_Special Construction Partial Streamlining
SC__Sidecar
SCS_Sidecar Streamliner

Yes, I have ballsed that up a bit.
It should read M/PG for Modified/Pushrod Gasoline or M/PF for Modified Pushrod Fuel.
Below is an excerpt from Gary Bakers email when I was thinking I could run my bike as M/PV being Modified/Production Vintage. This was incorrect and I will run as M/VG, Modified/Vintage Gasoline.

Here's Gary's explanation
`Firstly to clear up a few points ,to run in production class, all parts of the bike have to be "production" you cannot mix and match production with other classes , also the 'production " class is based on the frame ,not the motor ,therefore by definition all parts must be production and furthermore the production bike must be as it was made by the manufacturer unaltered in any way externally , but a production bike may be altered in any way internally ie engine mods so you cannot have a class M/PV,it will either be P/PV or M/VG or VF ,a bike altered in anyway externally from origional will be required to run in a modified class regardless of the unaltered production engine'

Cheers Mossy

Wow!!! This is interesting.

I guess I (or anyone else) can place what ever class designation they wish but where it all comes unstuck is when you claim a record and/or protests are filed and then debates are held on the interpretation of the rules. This is what I am trying to avoid before I get to the start line.

After reading the rules and discussions on this forum, I guess the sticking point is, can it still be called 'Production' as this will dictate whether it is M/P or M/PP.

I appreciate the healthy discussion as I just want to get it correct.

[Colesy]

Mossy

Thanks for that.

I wrote my last post before reading your new entry.

Hey, Ive been wondering what class the bike im building would come under, but seeing this post i think i know... Im using a prodution frame (motocross) , with road bike forks, road wheels (front 21-18) , fork tube style drop bars and bobtail rear, Does modifed mean frame only or does that include forks. The bike in is a suzuki RM 80 big wheel (2 stroke motocross) ive fitted kawasaki KR 250 forks with an 18" spoked front wheel, fork mounted drop bars, bobtail seat/fairing, besides that its original and stock. i think im M/PG 80
