G'day Giorgio,
I think the DVR2 is the best option. It will hide inside the old reg box. While your at it why not put in a dynamo belt drive kit to help with low revs.
Postage to over there is even worse than here .
Cheers
The Belt drive it´s really cool stuff!
My mechanic tell me to buy one just in case, but we are trying to make the bike as original as possible.
BUT! I want use the bike, so some parts must be more trustworthy and efficient.
I´ll start change the original 6v regulator for a DVR2 and see wath happens
If the regulator work fine at low revs, great! if not, I´ll have to buy the belt..
about the shipping here, it´s a bit expensive, the worse thing it´s the customs assalt!
we have to pay the parts + shipping + 80% tax
for several times already thought about moving to a bether country...
thanks for help!
