YZ 400, 99. Engine noise/loss of power
Posted November 02, 2015 - 03:49 PM
After noticing an oil leak during a ride and then a loss of power when accelerating I rode the bike home cautiously, the following day I was not home and my partner accidentally knocked the bike over and could not pick it up so it lay there on its side for about an hour. I also noticed the packing in the exhaust was damaged/loose.
I changed the oil and air filter and now the bike will not start. I roll started the bike but it stalled almost straight away.
Any ideas what could be wrong, any advice would be greatly appreciated thanks guys

Impossible to say
Not enough info
When was the last time you
- adjusted the valves
- serviced the carb and replaced the wear items
- changed the plug

That bike is reliable, but ALL off road bikes need regular service.
The words 'full engine rebuild' don't really mean anything without receipts and a description of exactly what was done, and by whom.
