    Since finishing the port match and any other modifications to the engine. The rest could be done easier mounted. So into the frame it went for the first time in quite a while with a nice fat 650 head to fill the frame in. Going to be doing a carb dip and clean, side cover gaskets, engine flush, and some other odds and ends and hopefully get her started up within a month or two.

        Added rear stainless steel brake line. Worked out good as I was able to use the stock swingarms line holding tabs.

          Made some headlight brackets. I need to go to the hardware store and get a couple bolts to finish it up:

              Good idea using the pinch bolts as a mounting point. Looks alot cleaner than using a clamp on the forks, just make sure those bolts are tight and wont vibrate loose. You don't wanna have your pinch bolts loosen up while riding!

              Question what did you source the forks from? Were they from the '92 GSXR donor bike?

                I'm probably going to throw some blue loctite and/or lock washers on the bolts of the headlight bracket when I get it finalized.
                The pinchbolts still work like stock. I stuck a spacer to pull the bolt out just enough that I can thread the headlight bolt in from the backside.

                Yes, those forks are off the 92 GSXR 750.

                  Started work on the seat pan. still in the early / developmental / thought stage. Unsure of how I'm going to go about much of it but figured this was where to begin.





                  Started dissassembly and dip on carbs. On the last carb in the bank I ended up with a beyond stuck pilot jet and a couple other snapped off bolts / screws from some bad corrosion. Ended up finding a mint set of the same carbs for a good price on ebay. Don't have a picture right now but they are clean, just a matter of jetting them properly.

                    began slimming down my rearset brackets. Left side is 99% done:


                    Right side cut the brake lever cut down length and width wise along with removing the spring from the footpeg to allow kickstarting (which is very important on a kick only setup). Was a minor oversite that turned into a bit of a hassle. Probably going to cut down the rearset mount to match the left side and tuck the master cyl somewhere.

                      Small update:

                      I haven't done much of anything to my bike lately but for very good reasoning. Besides for spending the holidays with family and the normal shopping, I've aquired a new job. Starting Jan. 3 I will be working in the automotive industry for a local performance suspension and engine parts supplier assisting people ordering and installing kits over the phone/ internet. Should be a blast as it's something I've always enjoyed. The pay and benefits are great.

                      With that said my build should kick up pace as soon as my new job gets rolling. Last year working as an electrician and things going downhill fast I only managed to pull in about 10K for the year. I'm looking to triple, possibly quadruple that with this new oppurtunity. Things are looking alot brighter for 2012.

                      Merry Christmas and Happy New Years to everyone on the board. This place and others like it havekept me sane during a pretty crap year and I'm thankful for it.

                        So I've been loving my new job and finally took some time to go check on my bike. We have a bunch of spare parts bikes laying around and I decided to try out a seat off a 70's CB350 twin we had. After a bunch of tinkering with custom seats I plopped this sucker down and it fit nearly perfect. All I have to do is some light bracketry removal on the bottom and fab up some mounting points. I'll integrate a taillight into the seat back. I think it works out good and gives it a little more of a retro look.

                          You might consider re-routing your cooler lines up and over the motor. I dunno how much it would really matter but the header temps around the areas you have them run now are pretty high. Might actually nullify that nice oil cooler...

The hardest part was getting the old race off the stem but that was only about 10 min. of me and bill hittin each side with some chizzles and a hammer. It went together perfectly along with some waterproof thick grease. All thats left on the front end is to remake up the steering stops which shouldnt take too much time.

                            Mocked up the top triple, guages, and some other small bits you cant really see in the picture.

                            Looks like a crate motor.

                              Finally have some more progress on the project.

                              Shinko SR741 150-70r17 - 90 shipped off ebay. Nice looking tire for the price:
                              My friends and I mounted it with 2 tire spoons, electric tape, and soap water. All thats needed is to balance which a budget homemade balance stand is in the works. Also mounted my rear brake strut to the frame:



                              Just another eye candy shot of the bike barn:



                              Have 3 different rear sprockets on order ( 45t, 46t and 49t). will be ordering a 14t and 15t front sprocket and chain shortly. I really wanna get the gearing spot on so I figured i'd get a whole bunch to mess around with.

                              More fun to come thanks to my new job kickin ass.

                                I came across www.gearingcommander.com and it's quickly become one of my favorite toys. Made this chart. Don't know if i'll be able to push her up to that RPM but I'm thinking why not? What's everyone else pushign their 550s and 650s to?
