Rotten gas (The original blog written on 15th Aug. 2007)

From holidays in May 2007 I started my operation to revive my "onboro ALFA".



First of all I tried to remove the rotten gas that was left for 10 years in the fuel tank, but it was not easy.

I thought I could remove it from the drain bolt at the bottom of tank.  But the bolt was sticking and it could not be loosen.

Then, I tried to remove gas from the fuel hose by activating electric fuel pump, but the fuel pump only did blank beating and the fuel didnt come.

After thinking for a while, I went to buy a hand pump for kerosene stove and a long vinyl hose to suck the gas from a fuel filler port.  AS a result of efforts for more than an hour with a cheap hand pump, finally I extracted 20L of horrible brown liquid and a lot of rust pieces from the tank.

I filled the tank with new gas…but of course the inside of tank is still very rusty.  It was just the beginning of my long way...

Clutch master cylinder overhaul #2: tough match

I disassembled the removed clutch master cylinder. And I found that the piston was heavily rusted. I tried to hit it with a hummer , Pushed the piston using the vise clamp like this.  However , the piston was heavily sticking by rust and it could not to be moved today. The brake master cylinder was replaced in the past , however , the clutch master cylinder was not.  Therefore , the condition of the clutch master cylinder might be worse. Tentatively , I would spray the rust-penetration lubricant from both sides of the piston and try again in a few days. If it doesn ’ t work , I would give up the overhaul and order the new part.

Tip to repair rubber parts

I disassembled the rear axle before.  There had been no progress on it because I started the repair of the fuel tank during my summer holiday. While painting the fuel tank , I repaired the torn rubber boot of the parking brake wire. I guessed it didn ’ t cost high because it was small rubber part.  But I wanted to try the repair method I read on the magazine article before. This was the condition before the repair.  The rubber was torn apart and separated almost. I used this self-adhesive type butyl tape.  I pasted lots of small pieces of the butyl tape on the back side of the rubber boot.  As time goes by , these tapes would melt and stick together.  After this I applied plenty of adhesive “ Super X Black ” on the rubber boot.  On the magazine of MOTO MAINTENANCE , I read the article that the motorcycle seat was repaired with this method.  So , I wanted to try it. After drying 1 day , it became like this....
