Latest Article: TOURING on a SECA II 600


1992 SECA II XJ600 coming out of years of storage.

13 years old w/ original 2900 miles. Not running.

Here is a previous project. Last owner purchased this bike new from a dealer in 1993 - put a total of 2800 gentle miles on it in the dozen years he owned it - and always stored it indoors. Here it is out of storage seeing the light of day. He upgraded to a Yamaha cruiser and agreed to sell it to me for a very fair price. Everything about the bike is in like new condition, with the exception of the fuel lines and throttle cable which need replacing, and the Gas Tank & Carbs - which need a major cleaning since the bike sat with gas in the tank. Check out the Factory Cowling - an option not many SECAs had in the day. The seat is also been redone - with extra padding installed.

There is some light rust on some of the fastners - and some other screws and the front brake reservoir is a mess, but overall the bike is like a time capsule bike.

The work begins - bike "naked" w/ the cowling, fairing, seat and gas tank removed.

And a better look at the 4 carb set up that's next on the list...that fule pump will eventually get rplaced too.


That's the air intake w/ filter at top - closed off w/ tape.


Ordered a Clymer Manual for the bike from eBay. The European version was called the "Diversion", and from England I located a rare factory option center stand off a similar SECAII/Diversion cycle.

UPDATE April 2006


I replaced my master brake cylinder and fluid, (the old one was corroded). I also swapped out most of the body fasters, installed a new battery & new plugs, oil & filter change, cleaned and polished everything, and adjusted the chain. After removing the rust the fuel tank and cleaning the carbs, I reinstalled everything expecting it to fire up...but it wouldn't. :-(

SO...I ended up having my local bike shop clean and sync the carbs. I had also replaced the fuel pump (vacuum type), and all the fuel lines. I had my shop install a smaller in-line fuel filter and ditched the factory one. While it was at the shop I had the bike inspected for Maryland. The bodywork on the bike had not been tight and rattled quite a bit, and I found that the front fairing under the headlight was cracked and causing a real buzz at 3-4000rpms. I use a small bungie cord to pull the two pieces togther which seemed to work OK. The lower fairing had a small crack which I epoxied and covered with a sticker. One of the valves on the bike is ticking - which is most likely due to its spring being compressed while sitting for so long...but it's an easy adjustment I'll have the shop do later. My tech said just ride the bike and get some miles on it first - which I'm happy to oblige! Here's the SECA II w/ my other bike..both running at last!

I got a nice Joe Rocket tailpack as you can see for the Yamaha - and it's great. I have a matching tank bag as well - which I'll use when I do sme one-up touring this summer. I touched up some of the paint and added a cool red reflector flame decal to the side fairing. You only see it at night when car lights hit it, or when you use a camera flash. I put a smaller set on my red helmet too.

Here are my two ponys ready to ride in their stable. I cleaned out and dedicated the second bay of my garage for them - and got a small remote for the garage door opener so I can roll in easily.


"The Seca II was Yamaha's entry in the 'bargain motorcycles' sector. When it first came out, its competition was the Kawasaki EX500, the Bandit 400, and the GS500E. It had many advantages over all of them. The motor was based on the Diversion 400 motor used elsewhere in the world. It was put in a full size steel tube frame. The Seca was a stylish motorcycle, and performed very well. It was comfortable, simple to work on, and a decent performer. The two valve per cylinder engine was no technological marvel, but it was reliable and easy to live with. The half fairing did a good job of protecting the rider from the elements. The Seca II was a very well rounded package. If a new Seca II's price is a best buy, then buying an old version of the exact same machine for less should earn the buyer a place in the bargain-hunter's hall of fame. Power in 1992 was 49.1bhp, with torque of 35.4ft/lb's. Wet weight was 450lb's."
