I just bought a Maruishi Roadace 7 from my local pawn shop and cannot find any information at all about it. I did a search and found a few topics on something called the RX-7, but I dont think its the same bike. Judging from the weight and components it appears to be pretty nice. I've got big future plans for it if it is...considering it's also in almost new condition. I paid $220, perhaps a bit much but I live in a small town where there aren't a whole lot of options as far as used bikes go. Here's the specs on it.

Triple-butted lugged steel frame, am I correct in assuming I****awa?
Suntour brakes and shifters, will probably upgrade the brakes and get new housing.
Nitto Bars and stem.
Sakae SX cranks, kind of lower end right? They dont seem to match up.
Shimano Silver Arrow shifters and derailers.
Sugino pedals and toeclips.
Laprade seatpost with a crappy Vetta seat, definitely upgrading.
Araya 700c rims with Suzue hubs.

So does anyone have any info at all on this? Is the number under the bottom bracket worth anything? The last two numbers are 86 so I assume that's probably the year of the bike. Cool, I would like to post pictures if someone can enlighten me on how to do it!
