Hi, my NC30 bike still has the first stock regulator on it. (German M Modell- 1991-21tkm). Its a SH611-12 with fins. After reading lot of threads about this theme, i am a little afraid that the reg (and some other electrical parts) get a fault. Whats actually the best reg/recetifier for the NC 30? I can get a OE Honda SH 633-12 (31600-KY2-703 31600-MV-4-000) which should fit for a lot of Honda models, each the NC30 too. Good idea?
Thanks for help.

I can supply you with a genuine honda reg rec that will fit your model for £65 deliverd

2003-2005 R6 reg/rec is the accepted mod of choice. Much more reliable than the Honda equivalent.

Thats exactly the point, some mean OE Honda some Yamaha and some...
2005-R6, its that not for injection model?

What nr. have the Honda OEM, an what the R6 reg?

The fuel delivery system makes no difference, it's all about the voltage regulation. I'd personally pick up a used R6 reg/rec for £25 off the net.

Thanks, and what nr have such a reg? there are many nr like SH611-12, SH633-12, SH645-12,SH650A-12, etc....

Any 5 pin reg/rec from an R6 (or Fazer 600) of 2003-2005 manufacture will do the job
