So i had a few hiccups with my 200x motor and needed some new rings for my arias piston. Called the Powroll shop number last week and it was returned this morning. I had a great conversation with the new guy running Powroll. His name is Terry Miller and he has machined a lot of the 200x and 350x stroker kits for Powroll. Anyway, he was telling me that he is now offering a 240cc kit for the 200x and has some new 350x stroker kits coming in. This is very good news for the Thumper community! I told him about 3 wheeler world and have high hopes that he will be a member on here in the future. If you are SERIOUS about purchasing a 200x kit (218, 240, etc kit) or 350x from Powroll please PM me and I will give you Terry's personal email. If you are inquiring only, call the shop (number is on their website) and terry will return your call (he is a very busy guy). This is great news for those of us that have Powroll engine components!
