Yamaha ybr 125 fuel injected

[Daniel96]

Hello to all, I'm new to the forums and I was looking for some help with my bike, I've recently picked up a 2008 Yamaha YBR 125 the fuel injected model.
The problem im having is once you turn the key the fuel pump primes as normal but its difficult to start and normally fires up on the second push of the starter button, does this sound like a normal 125 fi start up from cold??
Anyway once the bike is started and its warm its spluttering when giving it some revs, the guy I bought it from said he's done the valve clearances, could these be too tight??
I also received the bike with very minimal fuel in it and I think its possibly been sat since its last MOT ran out on the 03/03/20, could it be a case of bad or low fuel in the tank??

Any input is greatly appreciated

I'd put some more fuel in and then take it for an Italian tuneup before I looked at anything else.

Fresh fuel, new spark plug. Then see what occurs.

2008 eh?
Plenty old enough to have suffered at the hands of its owners
how many miles?

As well as the aformentioned fresh fuel and new plug, check valve clearances
when cold (0.10mm inlet 0.12mm exhaust)
It may have a somewhat sticky injector too so some injector cleaner in the fuel wont hurt.
Good clean electrical connections are advised too.
open check and squish some switch cleaner in them

DONT twist the throttle when you try and start it either!
efi engines dont like that

Fresh batch of oil won't hurt either.
