Bike is suddenly quieter than normal - Pointy 2014

OMO Im hoping you can shed some light on my issue,

A few days ago I realised my bike was quieter than usual, I thought it was just me but yesterday my dad and stepmum both pointed it out as they can usually hear me coming a mile away when I visit.

I know its not just in my head because ill find myself leaving it in lower gears as it sounds quiet, but when I look down at the tacho I realise im only in 5th. I have also noticed the gear whine a lot more, I usually cant here it except for in 1st gear.

Does anybody have any suggestions for what to look for? If I was to describe the noise difference, it would be like shes not as deep and there is no idle rumble (it actually sounds stock on idle)

*It has a Beowulf 380mm can with no baffle

are you sure that you are running on both cylinders?

Yeah no decrease in power, found myself doing 100mph accidently this morning cos its that quiet.

I had 325 syndrome on my last SV so know what it feels like.

The only other issue I have had is when I started her up yesterday morning, started fine but instead of the revs going high like they usually do when you start it, they went really low and then came up like nothing had happened. I dont know how low as I started it and walked back into the house, its never done that before.

could be something like a poly bag partially blocking the air box intake. or something on top of the filter.

unless someone has put a baffle or rammed something in your exhaust then it has to be the induction end.

Could it be that one of the 4 sparks has give up?

Ok ill check airbox tonight, Iv had a quick look in the exhaust but nothing there. cheers bib

could be.. pull each cap and see if it makes any difference.

how many miles are on the bike?

ooohhh and have you checked your oil lately.....

Oil, oil filter and air filter all changed 2 weeks ago (problem started approx 5 days ago) a lovely gizmo was fitted too

I have since checked oil level as soon as I noticed the issue (I checked because I can hear more engine noise as the exhaust isnt as loud)

Nearly 12k

OEM plugs should be good for 25+k no harm in checking them though.

Will do mate, ill report back later
