Just come across this little beastie anyone tried or running one ..

Used these on almost every race bike we have run until we started using pc3-r's with adjustable timing..

Make sure you run optimax fuel or super unleaded tho, as otherwise you risk detonation...

What sort of benefits can you achieve with one of these?

Cheers
