Gilera Vx 125 water pump, please help!

my water pump is knackered so i got one off a mate but its different,
mine has a black plastic bit at the top with 2 pipes going into it, 1 thin one to the carb and one thicker one going to a metal tube leading to the exhaust manifold near where it bolts to the bore,
my mates one dosent have the black plastic bit or the part where the 2 pipes connect,
also on the inside of mine it has a lump of rubber and what looks like a piece of foam air filter materiel behind that, mates one dosent,

now, i took a wild guess that mates one is from a dna but should still work, so i fitted it still and as for the 2 pipes, i also guessed they were something to do with emissions so i just blocked the two pipes off, all seems well but will i do any damage?


heres a pic of my old water pump and im pointing at the part my mates dosent have,
any ideas?

 

well i have now found out by looking on gileraspares that my original flywheel cover has a secondary air box and my mates dosent,

now the question is, does that matter? is it just for emissions and can i simply block off both pipes and not worry?

 

I've bypassed the system on a DNA 125 I had a while back, theres a metal pipe that comes from just below the exhaust manifold that I made up a blanking plate for. I'm pretty sure its just an emission based idea.

 

cheers davey, well i have ridden it about for an hour or so with the pipes from the manifold and carb both blocked and the bike seemed to runn a bit rough so i unblocked the pipe to the car and it seems a bit better but either way i now seem to have a flatspot on pull off :blink:

 

look i need some proper help so simple but its pissing me off so baddd , the sort of rubber bit on the ht lead that connects to the spark plug keeps slipping off also doesnt cover the whole plug what the fuck is going on , and why do i keep getting left by piaggio flys arrrrrggh i got a kevlar drive belt , malosssi clutch and variators , micron slip on exhaust , also just fitted new tyres ,oil change ,changed coolant , im not used to 4t runners had two stroke but im getting older and i dnt wana injure myself on them anymore but yh please tell me what the f is going on
