HI,

aquired nordwest a couple months ago, have done oil&filter, cambelt and chain/sprockets are next on list but in last fortnight the bike began to sound louder and is now tractorlike? oil level is good when bikes upright, fitted new sparkplug( didnt check gap?),havent checked airfilter as thought this would affect the running rather than noise. Any notions?

I wonder if the header pipes are blowing where they join or the silencer has developed a hole?

Loud is good just blip the throttle saves blowing the horn

U might be right u know

definetly worth checking, cheers
