Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

Thanks so much. The time instructions worked perfectly. But I have another problem . After assembly , we started the bike and have a strong ticking in the top end. Could give me some guidence on setting the rocker arm clearances. I'm not sure I did it correctly. I put the timing mark back for TDC the same as we did for timing. We set the rocker arm clearance at .004 at this point. Where did I mess up and what do I need to do to correct it???

When you aligned the "T" mark up, were you on the compression stroke with the cam lobes facing down? If not, you need to turn the flywheel one full revolution and stop on the "T" mark again and you will be on the compression stroke and the cam lobes will be facing down. You need the cam lobes facing down in order to properly adjust the valve clearance. If the cam lobes aren't facing down, the valves won't be closed all the way.

BTW, the valve clearance should be set at 0.003in.
