Well guys, I had a day of today.
After 2 1/2 years of rebuilding my 1976 CB400F, I finally rigged up a bodgy fuel cell made out of an old tomato sauce botle (1 litre I might add) and hooked it onto the fuel supply line to the carbs which I have just finished re-fitting with carb kits from Canada (Sirius .com) found on Ebay.
Wahoo!! she fired up first time. Lots of smoke out of the can but that was to be expected as, when rebuilding the engine I pumped heaps of oil into the cylinders before closing in. I didnt have the air filter or air box fitted so there was a lot of sucking noise, but she went really sweet.
The front end is now in line for a makeover and then around Xmas she might get a road trial.
This bike was bought from a wrecker and so far has cost me more to rebuild than it might have cost to buy a new bike. But at 30years old, she is now a classic and by the time I'm finished she will be a pearler.
Added a pic or two (hopefully)
