Hey if anyone could help me out, i've re-wired the bike thinking it was a loose ground since it happened the first time, just the other day after about 45 mins of riding mantaining a speed of 140km/h the bike remained running, but didnt not have enough power to rev beyond 3000rpms. once i turned the bike of it had no power at all, put a new battery in and it worked no problem. If anyone could help it would be much appreciated.

 

check the stator.. might not be connected if your loosing voltage. If the bike stays on then i don't think it has something to do with the battery tho. The fuel line and stuff is mechanical.. like the throttle.
I don't understand because if you were going 140km/h and the bike was only revin at 3k... you would have some major major engine breaking that would slow you down alot. was the clutch in??

 

sorry i wasnt clear in my post, the bike was running perfectly fine, i was riding it hard on the highway it suddenly started loosing power, once i pulled over the bike was still running but anytime i rev'd the engine past 3000 it was begin to stall, once turned the bike off and tried turning it back there was no power at all, the next after towing home i dropped a new battery in it and everything was working, i'm curious as to what it could be the battery that was in it was also brand new.
