March 22, 20215 yr Questions, angle grinder for port modifications. -I have modified several 2 stroke cylinders with Dremels with decent results, but never upper transfers because I don't have a small enough angle grinder. -I have a trials motorcycle engine TY250 Mono with 68 mm bore that I would like to work on the upper transfers. My 90 degree 1/4 inch angle grinder is too big. -I can't afford a Foredom cable operated with the assorted heads. -If I have to buy something, I'd like to be able to do saw cylinders as small as the 026 44 mm bore. -What is out there that could do a 44 mm bore? I can do electric or air. The low speed dental heads are cheap, but the drive portion is spendy. Are they terribly slow on metal removal? This would not be a business, and I have more time than money. I would hire it out, but it's not an easy option here. Advise?
