WHAT IS BETTER TO RUN 8mm OR 7mm PLUG WIRES. I ALSO AM GOING TO PUT A NEW IGNITION SYSTEM ON MY Z1R ARE DYNA IGNITION AND COILS A GOOD CHOICE ? SEEN SOME ON Z1 ENTERPRIZE. $120.00 FOR 3OHM COILS AND $120.00 FOR DYNA S IGNITION. GOOD PRICE?

Please type in lower case. Upper case usually denotes yelling, plus it makes what you're typing harder to read.
Yes, the DYNA coils and ignition are a very good choice. Plus DYNA is pretty good with customer relations and making things right if problems do arise.

Jeff at Z1 Enterprises not only offers parts at very good prices, but has the best customer service I've ever experienced from an online source!
I wouldn't want to have a gazzillion people calling him, but he's very knowledgable and willing to help people out over the phone with questions and very good suggestions.

Thanks for the advise. I'll try to get in touch with them at z1. Did you know anything about the plug wires? Thanks markoB)

I know on cars it can make a difference, because the electrical systems have more "power" than a bikes does.
Increasing the wire diamter flows the spark better and achieves better, more thorough combustion.
The 8mm wires tend to cost a little bit more though.
I'd suggest either e-mailing or calling Jeff to see if he thinks it would be worth the added cost to you.
He's very honest, and will give you a straight-up answer.

The kits he sells have 7mm wires and I'm sure they are plenty big.
