Dasa 89mm +4mm stroker is still 4200
My 89mm-91mm bore +4mm stroker is 3350 (this is 62t cylinder based but has custom sleeves, new stroker crank, new super bore head, with low to mid range porting/timing. And it hit VERY good for that price) Its a 900-936cc engine for 3350 usd, thats reasonable...
