clutch
i built a Indy blade and asked the same question to mk and they told me there is no need to upgrade the clutch as long as u drive with respect for
the standard clutch

heavy duty springs can be got from pdq for about twelve quid. Thats whats in mine with the standard clutch and no slip- yet! previous experience with
my previous blade engine suggest it wont be for long, but then lots of track days and visits to the 1/4 mile drag strip at craill dont help!!!

When you get the springs make sure you get the Blackbird springs and not the Fireblade springs. They offer more force than the uprated 'blade
springs and are recommended for use in a blade engined car. Search the forum for the part number.
I bought the 'bird springs and 'blade frictions (all Barnett) from PDQ - didn't need to fit the frictions as the OEM ones were still
within tolerances - hasn't slipped since

Hi there
I've got a ZX9R, using standard plates, but with upgraded 'Barnet springs'.
That said, I've not started the engine yet!
Cheers

I think you're talking about the carbed engine though, which uses MT-99-5 Blackbird springs. Id imagine the 2003 engine might be different.

i used mine as standard, worked fine for a while til i burnt it out. I fitted barnett springs and plates, feels much better now. Id change the springs
now and use the plates til they die, should last some time anyway.

Agreed, the stock plates are generally pretty good for bite/feel so if you can get stronger springs on them before they start slipping, it will be
better than leaving it stock and burning it out quite quickly, then having to fork out for new frictions etc too.

PDQ said its a different clutch in the 954 engine than whats in the carbed 893/919 blade engines.

My stock R1 clucth has lasted over 4000 miles now, including a couple of track days and two fully-loaded tours! Don't underestimate a standard
clutch - just don't ride it! 
Spin 'er off Well...

Yeh Id go along with that on the R1 as its a bigger/stronger clutch even when standard, but the blade clutch (carbed version at least) really does
need stronger than stock springs to make it last in a BEC IMHO
