I have a 2007 Yamaha 50TLR oil injection 3 cylinder. When it first starts it will run alright but after maybe 30 or 45 seconds it bogs down when you try to rev it up and will die completely if you try to go to WOT. I have changed the plugs and checked the thermostat (which is good). Its also runs really rough when idleing after it has started to bog down. Once it has started to bog down it will refuse to run at anything above idle. If you let it sit for an hour or so and start it up again it will run and you can get it to speed ( it doesnt feel like it has the power it used to) but when you let it down from speed it will go back to the same thing where it wont run above idle again. Any Ideas?
