Hi, I was wondering if someone can explain the performance difference between the blue and gold CDI's. My bike is an 88 J model with a blue CDI. Will the gold CDI make much difference to the performance?

Thanks

Ian

other than remove the 112mph restriction

no.

ok thanks for that. I thought it might improve performance. I clipped a bit of metal off in the speedo (very neatly) which removed the restriction. It now revs till it blows in top (on a track of course) which it didnt before. I'm glad i didnt buy one for stupid money on ebay.

hi guys , sorry to revive this thread but i have a question. i have two cdi's one blue label KY2 one which was in the bike with a M max parts corporation racing off limiter box so no restriction
the other was given as spare and it has a silver label KT8.

i see things about gold labels but nothing about silver

KT8 is for the CBR400 Aero so I dont think it will work for thr Tri arm

OH RIGHT IVE FOUND ON THE FIREBLADE FORUM THAT ITS THE DERESTRICTED CDI FOR THE OLDER CBR400'S IS THAT WRONG?

Yes its for this cbr400

Have a gold on my rrj and tried a blue on it once from a rrk but it did not run correctly (but worked fine on the k). Is there a difference between the rrj CDI and the rrk apart from the colour and derestricting nature of the unit.
