Just replaced the advance unit springs and still stuck open???

[pnedac]

Any help is appreciated.

I just got the new spring replacement set from MikesXS because I owuld hit the throttle and the advance would stay open. I figured that since the bike only has 5000 original miles that it must be because the part is just old and worn out, but now that I put brand new springs it still is sticking open. Maybe even worse!

Any suggestions on making it return. It seems kind of sticky and I do not think that it should be.

Thanks,

Pat

The rod passes through bearings in the cam shaft. They are dry and causing the shaft to stick. Remove the rod and clean/lubricate and all will be well. Stock springs were probably fine.

After cleaning and lubing (use a moly based grease), go back to the stock OEM springs.

After cleaning everyhting out (Thank you much) I have a bit better action out of the springs. I ended up still not satisfied with the tension and took an OEM spring and shortened it just by one coil. Bam! Now it has a good solid snap back. Should do the trick. I just did this to one of the springs.

Thanks,

too much spring tension and it won't advance at the right rpm, might not until 4000 instead of 3, which will cause retarded timing
