Corroded points plates

[billyhoyle]

Thanks for the info gents! I got the advance off without too much difficulty, and it was indeed rusty as sin and seized. Threw it and its bolt in an overnight bath of good old fashioned coca-cola and with a little coaxing from a screwdriver, it has freed right up! It's amazing how well coke worked to clean it up. Hopefully I'll get some time tomorrow to take it apart, clean it properly, and reassemble everything.

Well, I put the new points plates as well as the clean spark advance, and magically, spark appeared where there was none previously! Tried to start it, no go. Checked the batter and it was a bit low, charged it, and she fired up for the first time since I got her. Woo hoo!

Bit of an issue though - it will idle for a second, but then fairly rapidly revs higher and higher with no signs of stopping. I haven't set the timing yet - could that be the cause? I've cleaned the carbs, replaced all the o-rings, sealed the airbox and installed a new filter, new airbox and carb boots...my other thought is that the float height could be off...?

I haven't yet checked the valves either, just fyi.

Check the main idle is not set too high, check your throttle cables that everything is adjusted correctly. Probably something simple. The timing could make it idle a bit higher but usually it just runs really rough or won't start type of thing.

Bringing this back from the dead...bike is running and pretty much road ready at this point (I really need to start a build thread), with a couple of leaks to tend to but nothing major.

One question relating to the timing advance - when riding, the bike doesn't seem to want to rev past 4000-4500 rpms. I didn't try tooooo hard as I didn't want to push it too hard on its first run around the block, but I'm thinking this might be related to the timing advance, which could still be sticking (or may have seized back up since I freed it). Should I look into this?
