hi i have recently got myself a daelim vt 125 and it needs a bit of work. i am needing an exhaust for it but i might be able to make one from the parts i have the only problem is that the previous owner has snapped one of the exhaust bolts in the cylinder. the threads have worn as well so i will either need the have a replacement cylinder or if i can then have it reconditioned. does anyone have any advice.
