funniest thing i ever saw was the r6 cup at thruxton in practice, one managed to bin it in pitlane but before he got out on track, complete tit

Roger that Dave, cheers 8-)

I think I will be removing it all and go from there. Starter can stay til I am sure the motor runs OK and then it is whip it off time.

in club racing you are not permitted to get back on after crashing. :( :( :( :(

So sorry for being thick but in theory and for that matter in stages -

1. Bin Reg Rec
2. Bin Alternator
3. Bin Interconnecting Wiring
4. Instant Total loss

That all seems too easy ! no plates or parts required just a coupla bungs ?

Magic

Oh re replies will be keeping the starter for use in emergency also have two batts so can be exchanged between rounds or charged !!

Cheers folks

Total loss is NOT done in stages when running total loss you need to remove the rotating mass off the end of the crankshaft as the purpose of total loss is in theory (although its not quite that black and white) helping the motor spin up faster, You can do this easily enough on 400cc and most low ish powered 600cc motors without a problem but by simply removing the reg rec you are not gaining any of the benefits whilst loosing out on ALL the benefits of having a charging system.

Not true, you wont gain much it's true but you're not after reducing rotating mass but rather drag from the alternator, the drag increases with the load (ie how much power the alternator is being asked to provide), remove the load (ie disconnect the reg/rec) and the load reduces to zero. The drag does not reduce to zero IIRC due to eddy currents which just serve to heat up the alternator. The way then to remove all the drag is to remove the alternator. It appears some people also remove the rotor but that *is* to reduce rotating mass.

The reason to remove the reg/rec first is it's an easy first step which allows a (small) benefit without any grief to revert. If you can live with it then take the next step. If you are already sure you can live with it then just go the whole hog now and remove the alternator, wiring and reg/rec.

In all fairness it would be well less than 0.5 hp gained by unplugging reg/rec.

I do agree that it will let you know pretty quick if you can live with no charge system!
