“So once again, the king is now my guest. And why is this.....” my gas tank made a mess.
This is actually the continuing saga of my failed gas tank liner,

I won’t go over the whole gas tank liner fiasco again, it’s there if you’re interested. No, this is about what happened after I got my gas tank back the last time and installed it on my bike and tried to get it running again. Before Christmas, I spent a few days trying to get it sorted out. I had already cleaned all the melted gunk outa my carburetors and now I couldn’t get the bike to run well again. It kept popping out of the exhaust and idling poorly. No matter how I tried to adjust them I couldn’t get them dialed in, so I figured there must me something in the idle circuit still, so off came the carbs. Only this time I noticed something, a black stain in the intake tracts. A closer look revealed this, ahh , there’s my gas tank liner. Edit: To be clear the gunk shown in these photos was deposited by the melting of my first failed tank liner.
After seeing this, I took a compression test and my compression has dropped to 130 lbs and 135 lbs. it has gone down.
The other issue I was having is the clutch feels super sticky, like it doesn’t want to free up. With the bike in neutral, if I kick the kickstart to try and free up the plates, it won’t , it turns the motor over. If I start the bike and put it in gear the bike lurches, badly enough to kill the motor at times.
So that does it then, I pulled the motor, to clean things up inside and check for any more damage.
It’s deja vu all over again. I started pulling stuff of the motor, the head is coming off , I’ll pull the valves, clean all that up...somehow. Part of that gunk feels oily, part feels rock hard. I’m also going to pull the clutch out and clean the friction plates up. When I drained the oil , to me it felt sticky. I don’t know, it it’s all going to get cleaned up. Then back in the bike to see if it works.
I sure hope I can wrangle that motor back in, it had to have the top tipped out first to clear the frame. Going back in, it’ll have to go in bottom first and then hit the bolt holes, we shall see I guess.
Later, Bob
