My new number plates!

Hope everyone is having a great weekend,
While riding my quad just quit, I mean dead. No life on the dash, no crank and obesity no start. 
Had a quick look under the plastic, batt reading 12.7v power at the key switch.
Changed the power pack, still no luck.
Anyone else have similar problems?
I don't see a fuse box/panel, is there fusible links in the system? If so where di I start looking?

Hello All
I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

It's been a long time since I have used a forum, I was the admin of one for quite a few years, had thousands of daily active members, with lots of crazy posts and spammers, so I salute the admins. Anyway, just waving my greasy hands, Hopefully I can help others out.

I'm new to the mechanics of riding. I've ridden quads and love it, but I've never really owned one of my own. I bought this quad in pretty rough shape and have been slowly restoring it. I'm almost ready to kick it over, but I'm doing a little research before i add fluids. I'm wondering what kind of oil i should use. I know the specs call for 10w40, but with the age and brand of my quad I'm curious to hear an experienced opinion. And since I'm just getting started with this forum, I don't have access to the service manuals yet. Any and all advice is welcome and appreciated! Thanks and happy riding!
