finally got round to putting me modified baffle in , sounds great ticking over , rode with it in yesterday and it sounds good up to the 4 grand mark then the sound starts to go quieter !!!! don't know if it will be a permanent instalment tho , at least other road users could hear you with no baffle , I'd only gone 2 miles yesterday when I came across a load of tour de frog wankers riding 12 abreast and they didn't hear me !!!!!!! think i'll give it another try then might have to bin it !!!!
