yz timing

can anyone tell me how to set up wr with yz timing ? i am also told it has reliability probs an is harder to start, can anyone shed any light on these for me

For a '99 WR400F YZ timing conversion (& other "free" mods) check out below site. Also, there is lots of info on this forum. Do a search on 'YZ timing'. I think you need to consider jetting changes if you are making the time change. There is also plenty info on this in archives and in the forum. Good luck.
