I have an 08 WR450F, I have been having problems with the ignition cutting out. Has anyone had a similar problem? It seems to mainly happen when you wind the throttle right on, and the bike just cuts out, speedo and all. It has happened when i was just cruising on dirt road, and i noticed that sometimes it cuts in and out really fast, and while it is doing this the speedo jumps from super fast (110km/h) to Super slow (10km/h) when my speed is no where near either. It is a real problem when trying to ride over logs, rocks, puddles etc, because you can't get the wheel up in time. I spoke to the bike shop about it and they said spray WD40 down the key slot, but it doesn't seem to have helped, any help would be greatly appreciated.
