Yamaha Hard startng

[ParaPros Racing]

Hey peps..

got a rhino and is very hard to start when cold very hard..

was not like that in past just started doing it.

is there some kind of choke or relay that will go out
to make it hard starting???

when its warm there in no problem at all ...

Thanks guys..

Hard starting on a 4-stroke dirt bike typically means that the valves are way out of adjustment or low compression. Have you checked either?

EFI or carb? If it is EFI do you have a fuel controller?

Low voltage can effect EFI and spark. Battery ok? Have you checked fuel pressure?
