I bought this 1978 XS1100 E 3 months ago. it had been parked semi shedded (1/2 of the bike was under the 20 foot roof of an open ended quancet) for 15 years with no storage steps taken. The bike had many problems as you can imagine. All of these problems were actually overcome relativly easy except the engine I got it running in a very short amount of time and labour considering the storage conditions. Kinda cool what happens to gas after 15 years! Who would have guessed it tries to turn back into a dinosaur.
the problems were flooding backfireing, poping in the exaust surging the only time the bike ran good was hard acceleration above 4500 rpm.
Things I did to remedy the problem.
over 40 hours into the fuel system:
- Flushed tank
- checked and cleaned fuel cocks
- compleatly dissasembeled, cleaned and reasembled carbs (so many times I cant remember them all)
- Changed needles seats and floats on all the carbs.
- Changed the carbs with a known good set (ran at the race track three days before).
Well over 20 hours into electrical system.
All the parts changed were from the same bike as the carbs. This bike ran the quarter mile before and after I changed the parts.
- Changed TCI box
- Checked and Changed coils
- Checked and Changed entire vacuume advance and pickup assembly including wiring right to the plug behind the fuse box.
- Checked and Changed Spark plugs.
- Cut all conections in fuse box and installed grommets to ensure proper connection
- Disassembeled, cleaned, reassembled and checked every electrical connection switch and button (and I mean every single electrical connection). including the tach and speedo ( there were other problems here also that i remedied).
The solution to all my bikes problems is so lame I still cant believe it.
THE VENT TUBE FOR CARBS 1+2 INSIDE THE STOCK BREATHER BOX WAS PLUGGED. <I can just picture this little midget spider pissing himself laughing at me>
Thats it! Works great! Goes like snot! I feel like break dancing and I hate break dancing!
I am not a mechanic but I guess a few might consider me mechanically inclined. Basically I have been blessed with the ability to remain broke enough to disqualify me from purchasing new toys, so I get to buy and fix other peoples extreamly broke ones. Anyway; about 90% of the specific knowledge which allowed me to do most of the following tasks came from this website although the solution to the problem was not found inthis web page all you folks still must pat yourselves on the back cause you have imparted me and others visiting this website with a ton of knowledge. THANX EVERYONE!!!!!!
