Alroght lads, the other week me an my mate met up with another lad on a dt an we ended up full throttling them everywhere in high gears nearly topping out, when i stopped i smelt a horrible burning smell coming from my bike, then noticed abit of smoke slowly coming from tip of my dep end can, i thought maybe headgasket but coolant was fine and i had headskimmed an new gasjetmonth or so back, so drained gearbox oil - just under 750ml but never left it to drai just waited till it stopped, so not crank seals.
So thought maybe my packing, bad idea listening to some pikey on you tube saying get the blow tourch or heat gun down it to burn all the carbon out... ended up with a big jet flame coming out for a good few mins hahahha
Then i stupidly did my dep end can, with packing still in lol, im going to stubby it soon an repack so not too assed about that, but problem is, since doing all this my bike sounds silent?! with my helmet off its loud, but it used to soudd mint an loud even with my lid on, now with it on i can barely hear it hahah, peerformance hasnt changed from what i can tell an plugs still fine (running rich on fuel an oil - Probs why my exhaust was filled with carbon!)
what could be the cause of this? only thing i can think is that my pipe was blowing/not fitted correctly an now it is? or somethings plugged up in it lol
