[QUOTE="stevew51, post: 10639, member: 1684"] [b]Power loss problem[/b] Thanks for the reply, I also think this is a fuel problem. With the bike on the rear stand I can bring it up to full speed with no problems. So it has to be under load for the problem to show up. Lack of fuel would definatly do this but I have been through both carbs from tank to exit flange and I can find nothing wrong, The mag might cause this power loss also, due to the higher compression in the cylinders. But why would a mag fail at a high speed when even a weak mag will jump a 3" arc. Possibly a short or a ground caused by centrifical force or a thrust bearing failure. I've tried pressing down on the ticklers during these power losses to see the effect and it makes no difference. I've tried decreasing the spark plug gaps and it has made no difference, either. Compression on both cylinders, hot is 120#, which is good. Let me know of any break throughs w/ your problem. [/QUOTE]
