For me it is, I want to shop around for the best deal. I also like to fit and balance my own boots, another cost saving.

As Tim has not yet posted, I can confirm with Andy that after one race let alone one full meeting the HR Diablo's on a 620 have lost there initial grip and start to slide noticably.
Apart from that they are a good reliable and consistant tyre.


Chris:burn:

The two flywheel pickups for the ignition triggers are on a slotted bracket. you can get about 8 degrees of advance on there.......if you wanted ;)
In short, realistically, no you couldn't police it. You can move them 2 degrees tightening the things up.
It's a red herring that would take up valuable time/resource IMO.

Neil,

Well put and it would require a protest and an engine strip to prove.

Chris

i agree 100% with all above as nelly knows what he is talking about rather than some other people that frequent this forum

A strobe lamp would do. :D

That isn't the issue, if adjustment is there thats why its slotted but that is only for the static/idle advance the igniters provide the advance over 3k, and as Nelly says there is no advantage with them.

Run too much advance with incorrect RON fuel and it will pink like hell and get you nowhere.

Yeh but....
 

If we only ever spoke about what we knew about the world would be a very quiet place....

we'd never learn anything new...

or have anything to whine about....

or laugh about....

As per Skids post re pistons.

I looked into this and they were £300 for 2..
But I understand now you have to buy the cylinders ?

Mine after 2008 were well worn and scored and when measured were well
under tolerance.

JE pistons could be a option as they make 4 off to order.
and half the price :)

Also for next season The Scruts will be hot on shark fins and they will need
to be like the one Chaz had made up ( I got pulled up on mine at CC and bernie explained to me and showed me Chaz's template)

Thanks for my shiney new one Chaz :)

Yeah, but to what purpose. The facility is there, as standard, to adjust the ignition advance/retard. One DD'er could argue they had no idea.... plausible. The other could argue that having measured the TDC point the stock markings are out. Very plausible.
The pickups are the trigger for the CDi's. Move the plate 2 degress and the whole curve is moved 2 degrees. The ignitors simply carry the curve data. There's your advance.....

Why then would you go on a mass witch hunt for the either the DP ignitors or altered pick up positions?? It serves no purpose
The nett results of any tweaks to the ignition are neither here nor there.

IMO, the only mods worth any significant gain are flywheels, pistons and heads. These are easy spots and the tests are well known. Why spend 50 quid on a protest and waste the time of the officials chasing pickup positions when you'd get more advantage from a wearing a slicker helmet or tucking your elbows in a bit tighter.......
It's a waste of resource and time. The DD is supposed to be a simple series.

Never mind all this tech talk. MORE LAPS PER RACE PLEASE. 8 seems to be over so quickly or is that just me being a slow starter. LOL

Keep it as cheap and easy as possible.
