Hey guys, i normally do all the work on my bike myself. The bikes a GSF250v, It has VVT on the inlet cam and the valve clearances are a pain to set. I finally tracked down the workshop manual and there's actually 24 spots you need to measure the clearances and use shims just to set the intake cam. So i thought bugger it ill let the suzuki service dept. do it for me. Anyway. I was complaining of hard starting when cold even though the carbies are clean, adjusted, choke working fine etc.(hard starting can usually be attributed to inlet valve clearances being wrong, from what ive read) And the valve train is also very loud/rattley. So what they did today: Adjust valve clearances(apparently inlet were "spot on" and didn't need adjusting and the exhaust were too tight so they have been reset.) Balance carbies(usually should be done when you do the valves) They also did a compression test which had good results. They replaced the spark plugs while out as they were a little worn looking. Also chucked some "cleaning additive" in the fuel. So i picked it up. First thing i notice when i start it(its already hot as they just finished work) - valve train is waaaaay louder than it was before it came in! Not quite what i was expecting, i was expecting it to hopefully be quieter. Apparently the valve train is always loud on these because of the VVT(or so they tell me anyhow) but it seems quite excessive to me. Like if you step back from the bike when its idling the engine noise almost overpowers the exhaust(and its got quite a loud pipe on it) They had set my idle speed down to 1000rpm, so i put it back up to 1500rpm and rode home to see how it goes. No noticeable differences in engine performance, but the engine is definitely alot louder and more rattley than ever. So i get home and jump off. Second problem: I notice if i give the throttle a quick sharp rev up to say, 5000rpm - the revs take a while to come back down to idle speed, just drop back to around 2500rpm and then slowly fall back to 1500rpm idle. However if you just slowly bring the revs up with a small amount of throttle and then let it go, the revs drop back straight away like they should. Its as if when i quickly open the throttle a large amount like that, something sort of even jams a little bit. Does anyone know what could cause this? What do you guys reckon i should do? The above costed me $369 and i cant say that im exactly happy, as if anything in my mind the bike is now in a worst state than when i dropped it off.
