Right then, here's a question I fear I'm going to have to find the answer for myself;

Does anyone know (and will they tell me) the difference in static timing between an mc18 flywheel/NSR crank and a PGM-II RS flywheel/crank (with the RS set to it's stock timing)?

So, that'll be a "no" then?

Cheers

For info, with an RS PGM-II and mc18 flywheel using 50/50 Avgas/UL running the flywheel 3° retarded is considerably better than 2° advanced (which hits a brick wall at about 11,500rpm) and slightly better than 1° retarded.

Don't you have one of those Ignitech boxes that lets you curve it anyway you want regardless of the flywheel?

No, you can tell from the way I have a 100% race finish record.

They are that unreliable? Perhaps another brand?

Other than reliability, does the PGM have anything else going for it?

You tell me, you're singing it's praises on the RGV forum.

What, the PGM?

Reliability is a big concern for sure, and other than lack of maintenance killing them off (but hey what's a FET between friends, no biggy to replace), the PGM seems ideal in that respect, so all good.

What about tuning though? It seems that the only way to get around the PGM/SAPC (because as far as I can tell it's all just the same shite, different bucket) restrictions is to fit an adjustable unit? I mean, you can interchange things like flywheels and woodruff keys, but that appears to affect the whole curve, so helps you in some places and hurts you in others?

Do you know what has made the Ignitech unit unreliable for your competitors (I assume that was implied by your post?). I mean, are the units themselves giving out, or is the typical lackadaisical approach that most people take to wiring/weatherproofing on bikes that's causing trouble?

It appears to me as HRC did such a good job there is very little (no) effort being put (in the UK at least) into getting power from the NSR any other way.

Ahhh you include the HRC CDI under the PGM umbrella. That makes more sense They're adjustable right?

Not really, and unless you've got a lot of F3/RS kit no better and at times somewhat worse than stock.

Shockingly by spending millions of Yen on research and testing Honda got these roadbikes to be pretty good* and HRC got the race bikes to be very very good indeed.

*no other Jap homemarket restricted 250 can make so much power so easily; any mc18 or mc21 in reasonble health will get very close to 60bhp on Steve's dyno with nothing more than a tiny wiring loom modifiction.

Not really adjustable?

Oh, would be nice to think Honda spent more than a few million yen developing the NSR even though it's a two stroke

You're on about 80's technology, adjustable flywheels and the like, not (f'instance) 6 degrees of retard at 11000rpm, 14 degrees of advance at 9000 and 100% P/V opening at 10000 rpm.

Do you think that by using just a PGM and adjustable flywheels and the like, the guys from Tyga could have obtained the same curves from their 300 kit bike?
