try reading the rules rather than making your own up

1.7.1 The following items MAY be altered or replaced from those fitted to the homologated motorcycle:

Any type of lubrication, brake or suspension fluid may be used.

Any type of spark plug.

Any inner tube (if fitted) or inflation valves may be used.

Wheel balance weights may be discarded, changed or added to.

If used Wheel balance weights must be suitably taped.

Gaskets and gasket materials.

Instrument and instrument bracket and associated cables.

Painted external surface finishes and decals.

An interesting discussion and one I that I've enjoyed reading (even if I am in anorak mode for a while).

A question:

If someone has a big end failure and NEEDS to rebuild and finds the crank is scored:

Does this then mean that for DD racing (using our rules) it means a replacement crank straight away???

Also -
My basic impression of 'balancing' is that it matches components (or, yes - alters them) to reduce vibration and hence increase reliability....

But perhaps someone might like to explain further

Then go through EVERY DD bike and make sure NOTHING on any of them is modified beyond your interpretation of the rules Kev. Thats the only fair thing to do...or adopt a common sense approach and accept that balancing does NOT involve modification or polishing or lightening, and neither does it give any performance advantage whatsoever.

Nog, how was your crank balanced?
If it involved removing material in any way then the rules say it's not allowed.
Factory tolerances? Was the item found to be outside these tolerances to start with? If not then your arguement for reliability falls down, it's good enough as it is and doesn't NEED balancing.

For what it's worth, (assuming material has been removed in order to balance it) I don't see what you've done is giving any noticable performance advantage, so personally wouldn't have a problem with it.
BUT... it's subjective to opinion isn't it? So what must be done is simply follow the rule book and not have an entrant try arguing that his/her opinion is of higher importance than the written rules we've all subscribed to.

too much sense in this post....


if its just had parts mixed and matched, but not modified and standard parts from standard ebngines, surely thats fine isnt it? only if its actually been changed to bring in to whatever tolarance and has it therefore been modified. Thats how I read and interprit the rules, seems simple?!?!

Ok, that seems fair enough.....

...but now you rather shoot down your own argument. If it makes it smoother/more reliable then is that not giving you an advantage over someone who does not balance their crank?
