Hi everyone,
We already ran 25 hours on our yz450f 2018 here, and spent more time wrenching than riding.
First, the design of the airbox is just a nightmare. In sand condition, you should have a Dyson in the van, remove the cage and change filter every 30 minutes. We changed for the twinair power flow kit, but it's not better.
So we had to change the cylinder and piston after 15 hours. Already $500.
Then we had problems with the starter. The stater ran 1 time on 10, we checked the starter and changed the part behind the cutch basket. Now it's ok... for 20 hours again? $600
Fuel pump was dead at 15 hours, impossible to start. There is no solution to change a filter or clean. $300
Front rim is like a 8.
Clutch faded in 10 hours.
Clutch basket had to changed at 20 hours.
Now the bike doesn't want start again, we changed the fuel pump and checked the valves but doesn't work.
Besides that, the bike is awesome to ride. The chassis and the power make a perfect match.
Do you guys have issues with this bike ?
