M18 Bultaco El Bandido MK1 1968
Belonged to a family friend who regretably Passed away many years ago. His toys remained tucked away in the garage for the last 20 years. I doubt the bike had been started for almost 30 years, and his wife, a very good friend, asked if I wanted his old bikes (Combat Wombat came as a package deal).
As out of the garage:
Cleaning up nicely. Got the carb looking good...lotsa, lotsa varnish. Gas tank cleaned up nice. Cleaned the petcocks...lotsa baked on grease/dirt.
Petcocks dissaembled and restored.
Degreased and power washed the engine/chassis. 30 years of caked on, an hardened, grease. Will take a lot of detail cleaning to complete the job.
Engine is free. Can't say the same for the clutch. Reinstalled the carb and fed some gas/mix temp. Did fire a couple of times, but I need to get a manual before I start tinkering with ignition etc. 'Tis a beast to turn over, lots of compression. I also want to do a full leak test before I go too much further (seal exhaust, build a test gauge/pressure valve for the intake to test seals etc.)
11;00 UPDATE: We have sustained fire. Won't idle. Need the manual (Ebay - shipped today), but proves out the ignition/spark. Clutch plates freed up. Ran just enough to blow out the spark arrester and fiberglass. Needed cleaning anyway. And upset my wife & her favorite 10-11 show plus the horses across the way. Won't idle. Suspect plugged pilot jet.
Lesson for the day. Put on your MX boots before kicking this beast over.
Update 4/9/12 Received a rebuild kit for the Amal 392 that I was waiting for. Pulled the carb back off and as I suspected, the Pilot jet was clogged which was why no idle. Not much to the rebuild kit, Just a bowl gasket, banjo bolt gasket and two o-rings for the idle and idle mix screws. BUT now it runs, starts easy, idles, and the idle mixture screw works as designed! Just the temp fuel feed so I did run it under power on the driveaway before the temp fuel source gave out. I will have to remount the tank, air cleaner, seat to give it a better go then set up to do a crankcase air leak-down test to see how the crankcase seals are and move this to its own thread under 2-smokes.
The tank and seat back on to test the tank and fuel system.
Note the individual clamp on handlebars.
Even given that handicap (right shift/left brake) I took it easy, but it is a natural wheelie machine in first at most any engine speed. Only got into second on my short runs. I can see why the reviews from its time said it was a tough beast to tame. Fuel system is a go. Clutch/drive train are a go.
Now, to what degree do I do a restore? The forks need rebuilding, as does the steering head, I can feel the bearings lumping along in the steering head. More story for another day. And I need to start working on my right shift skills (not as important as left brake skills, though).
