Alright already! :)

Fall is sloooowly creeping up on us here in North Florida and I’ve started riding again on occasion so I guess I should start posting a bit.

Thanks to Ben (and the rest of you, you know who you are) for the kick in the arse… He wrote in:

“Fall off the wagon and post some more stuff, my morning ritual is getting staler without any good cycles to admire and get some inspiration from.
You could add some shots of the bike I wrapped up this past spring! 4 photos attached.

It really is a nice build so here we go. Oh and I’ll start digging to the e-mails here shortly. Stay tuned.



A Simply Epic (and well documented) CB550 Cafe from flying J Customs.

Monster thanks to Jason Moore for sending in this outstanding build. If you didn’t read his full description below then you missed the link to his very thorough build thread over on SOHC. Go check it out. If that doesn’t get you in the mood to build a custom then nothing will. An while you’re at it check out his Website Flying J Customs For more fantastic shots and builds.

This has me in the mood to get back in the shop.

I bought this bike 5 years ago. It was on craigslist and was a non running pile of junk. I fixed it up for my girlfriend, now wife, to ride. At least that was my intent. But after i finished building a cafe racer out of my very first bike,a CB750F, I had discovered what some would call an obsession for building bikes. So with the 750 done I turned my attention to the CB550. I stripped it down and started to work out in my head and on photoshop what I wanted the bike to look like. My inspiration was drawn from websites like pipeburn and tons of google searches for cafe racers. I wasn’t totally sure what I wanted until I talked to Richard from TAB Classics. He sent me a picture of a cb550 frame with the norton sprint tank on it and I was sold. Then I found the fairing on ebay and things just started to snowball. I didnt want to just build a good looking bike I wanted it to be fast too so the motor was ported and bored out to a 592 with a hot cam and a dyna 2000 electronic ignition with mini coils were added. I towed the bike 4 hours to Los Angeles to have the exhaust custom built. The rest i did my self. I did all the welding on the frame, built the motor, wired the bike from scratch, laced both aluminum 18″ wheels, ect. I added a second disc and caliper for improved braking as well as having the discs drilled and lighted by 2 lbs each.

Its taken me 5 years to build this bike. I have restored or cafe’ed 6 other bikes and sold them since i started this bike to help pay for this one. They served as funding as well as practice to hone my bike building ability.

Here is my start to finish build thread, its a little long but has lots of pictures.

An excellent RX-K 135cc Yamaha Cafe from Malaysia.

I’m getting a real soft spot for the small cc customs and this is certainly no exception to that.  More proof that it does not take huge money and big cc to build a cool bike. Congratulations Amli. name is Amli from Malaysia..this is my weekend project..just completed 3 weeks ago..This bike originally is Yamaha RX-K with 135 cc..I decided to convert it to Cafe Racer..This is the end of the weekend project.
