Aniket Vardan is announcing that he will make available a kit so you can build your own V-Twin Royal Enfield engine. You'll just have to supply the cylinder heads, he provides the crankcase only in order to keep the cost as low as possible. Unfortunately, the engine does not fit in the usual bullet frame, so you'll have to stretch it. So it will not be an adventure for the mechanically faint hearted. Congratulations to Anikhet for this remarkable development!
