Fresh rebulid and I almost broke my foot..help!!

(1/2) > >>

Krider:
I have just done a fresh rebuild with the crank balanced new piston ect. ect. When I tired to start my bike it almost broke my foot from kickback. I got the beast started and it idled perfectly and just putted around for the break in. When I tried to start it again of course it took a few kicks and every kick gave major kick back. It started and I rode it around a little more trying to open it up but was not making power. I left for work on a business trip and I?m trying to think what could be wrong? Could this only be ignition? I don?t think the kips system could give produce this sort of kick back. I fine tuned the kips valve can someone help.  

thanks

doordie:
Look after the "metal thing" who put flywheel in right position at crank.It happens it brokes and gives wrong timing!  :evil:
(Look at search funktion about KIPS). :wink:

Krider:
I put the engine back together and I don?t understand what you mean by metal plate? I guess what I?m really asking is timing the only thing that could give that sort of foot breaking kick back?

doordie:
Woodruff key! :oops:

As Doordie has said the woodruff key (the part that holds the flywheel in the right position on the crank taper) can break and the timing can go all to pot.

Remove flywheel and check it's ok.
