I stripped it down installed the Mikes 750 kit. New timing chain and guide. Pamco ignition complete rewire. Built the battery box, new seat post cleaned up all the grind marks and filled with welds regrind Welded and filled the whole where the back loop was cut off. New fork seals, cam seals. Gutted a MAC 2 into exhaust muffler and split a glass pack and installed in the muffler. Cut a stainless exhaust tip and made my own reverse cone muffler not loud but louder than stock. I soda blasted all the motor. Sand blasted the frame wheels case covers valve and tappet covers, triple trees, calipers shifter foot rest, etc. Painted my tail section and tank. I custom mixed the Yellow and it has gold pearl and a hint of rainbow pearl." Read more...

It was a close race but, Retiredgentleman took the win in the November XS650 of the month contest. The contest was for XS650 Specials, Special IIs, and Heritage Specials, 1978 through 1983. They could be stock or have some mods, but needed to have the stock "Special" tank, forks, and have a twin shock rear suspension. Retiredgentleman actually tied with sseres during the voting, but won in one day "deathmatch" poll to take the win.

Retiredgentleman has had the bike for 6 years and has done a lot of work to it over that time to make it the bike it is today.  It has some modifications to make it safe and reliable such as a top-end rebuild, Pamco ignition, modern ignition coil, new solid-state regulator, and a new modern rectifier.  It also has Brembo calipers front and rear for better stopping power.  Last year the bike was professionally painted (it used to be bright red) and had a pristine OEM exhaust installed.  RG says it's "a fun bike to ride and very easy to work on... a real enjoyable hobby/sport."

Just like last year, a presale is being held to make sure everyone gets the exact garment, size, and color they want. The presale will go until 11pm CST on Saturday September 15th. After the presale, only a few extra shirts will be ordered, so colors and sizes will be extremely limited... To make sure you get the shirt(s) you want, order yours today! Check out the shirts!

Tron's '77 takes first place in the daily rider XS650 of the month contest for July! Here's what he had to say about the bike:

"My xs650 is my second bike, first being a cbr 600 plastic toy. I brought the bike back to life after being dead, hidden away in a shed since the 80s. Back in its day, it had been toyed with a bit, butchered a bit, and given a god awful 80's airbrush job.

I went in knowing nothing at all about the mechanics of motorcycles, and resurrected it from the dead, into a mean, havoc wreaking, daily smile creator.

I have documented the work absolutely horribly, and wish I took the time to take more photos and update the build better. I ride the bike daily, rain or shine, about 20 km's into work. On my days off, I hunt down the best forest roads and back roads I can find.

Yes, I ride the piss out of it dirt and pavement." .... Read More

Also see Tron's build thread for more details and pictures.

This month's contest was for daily riders and we have 5 great entries. The contest ends in a few days, so check out the entries and vote!

Have a look at TeeCat's 1973 TX650 mild cafe-roadster, the winner of the April 2012 XS650 of the Month Contest. TeeCat brought the bike home in August 2007 as a forlorn non-runner, but he could see that the TX had the mechanical and cosmetic bones of a respectable resto-mod. So, with a vision and a huge assist from countless dedicated XS650.com members, TeeCat embarked on what would be a four-year stint at "Classic Bike University". Sporting the comfortable posture of a roadster and an understated but signature cafe bike personality, this '73 features host of electronic, mechanical and cosmetic updates that delight - and perhaps even confuse - the fond memories of classic Japanese bike lovers here at XS650.com, on the street, and at the pumps. Have a look at a detailed work list in the April XSOTM voting thread!

The March XSOTM contest was for restorations and survivors only. Yamasarus' XS1 received 65% of the votes! He took a year to gather parts and the build time was just 8 weeks! Everything mechanical was gone through and all parts were polished, painted, plated, or replaced, and yamasarus did all the work himself except for the chrome plating. It turned out beautiful! Check out the before and after photos!

Clutch spring screws can be a pain in the ass to remove. An impact screwdriver is usually necessary and sometimes they don't even work when the Phillips head strips or the screw snaps. Notice the thin threads on the screw on the left. The one on the right was modified by member kent_in_kc so they should never be a problem again. Upgraded spring screw kits can be purchased for about $30, but if you need it done now or are short on cash, this is a good alternative.

Read Kent's thread on how to modify your clutch spring screws so they will never be a problem again!

This beautiful mono-shock XS650 was built by Chad Goings and his father Bill Goings. They are from Wichita, Kansas and spent two years working on this project. They designed the bike around the mono-shock and careful thought was put into every aspect of the design to keep it simple and clean. Great work guys!  Check out more photos of the finished bike. View the build thread on 650 Rider.

Several XS650.com members have posted wiring diagrams for the XS650 in the Forum.  Maybe one of the diagrams will be just what you’re looking for.
