loud noise when started SV650

Hi everyone

I recently purchased a SV650 which I cant legally ride yet but I have my Mod 2 booked. 

Basically I have been turning her on to keep the oil and things moving, which I do every 2 days normally however since earlier its been 4 days

Anyway when I turned her on there was a fairly loud, high pitched bang, but she ran fine afterwards. I turned her on and off again and she started up perfectly fine except once where the bang happened again but was nowhere near as loud. 

I ran her up and down the drive in first and I couldn't hear anything wrong but I was just wondering if anyone could give me some information on the matter.

Cheers everyone

Frequent starting

It's not good to keep starting up the engine like that with no work, then turn it off again. Idling is bad for engines, it damages the spark plugs, and doesn't do the cylinders any good. You might have had a build up of unburnt fuel through not letting the engine run properly at optimum temperature, which you won't reach unless the engine is under load i.e. not sitting in your garage revving pointlessly!

My advice is leave it alone until you can get it on the road and test the engine properly.

Once every 1 or 2 months is fine to keep the battery topped up.

Yea, I wouldn't worry too much about starting it up every so often, as downshift says, once a month should be OK. I'd spend my going over all the exposed bits with ACF50... get a good coating built up ;)

hiya fazerish

alternatively, make yourself someones bestest friend ever in the world , by filling your bike full to the brim with Saudi Arabia's finest then asking someone to ride it ( lets say, every sunday afternoon )and giving it a good old tanking around the local twisties at your expence , untill the time you are qualified to do so yourself , im sure there will be no end of offers .


ps . make sure the person is insured and qualified 1st

No one has said it yet but what you've described is a backfire, ie: ignition of a little unburnt fuel  which was left in the exhaust after your previous cold (ie: rich) start. The occasional one doesn't do any harm. Always makes me chuckle (and jump) anyway.

thanks for all your help. 

im glad thats all it was and i wont be starting the bike as much. 

and yes the bang gave me a heart attack because the instant thought was "SHIT MY EXHAUST DROPPED OFF"

but obviously that was just from the instant scare, Im not that stupid =] promise lmao

Thanks again
