Hi, I'm kinda new to this forum and just need some general advice... Basically i have a new standard exhaust to fit on the bike (it looks different to the one its self). The bolts that needs unscrewing from the main engine part when it meets are seized I've tried WD40 and it still hasn't worked... I though instead of blunting the bolt heads i thought id get some advice on how i can remove them to put on my new exhaust. The bike seems to have some sort of sealer stuff on it which is flaking off looks very stupid as well and one of the bolts is covered in this which looks bit like a cone and is also covering the riverty bits Wondering if it would be worth taking it to a garage and then getting them to fit it and de-restrict it at the same time but wondering what the cost is likely to be? Sorry for my lack of technical words but i have alot to learn and looking forward to it! I'm 17 and i have a DNA i wanted a 125 but for 250 quid for the bike, Bike jacket worth 200 quid and a helmet worth 100 quid i cant turn that down . that was from a friend - And before i get judged i respect bikes and don't intend to tune it and kill it slowly like most people my age with bikes and the reason i want to derestrict it is personally i think 30mph is dangerous Thanks for any help or advice SAM,
