Fresh KT100 engine just back from Daniel Woltjer last month. I bought this engine from Daniel new last year and put 9 hours on it and sent it back to him for a rebuild. I have the Dyno sheet it’s a National caliber engine! I ran it for 20 minutes since rebuild and pulled it back off. I decided to go to the x30 next year and I will finish this year on another Woltjer motor I have. Looking for $1100. Dollars plus shipping. Can also combine with a mount and Horstman clutch if needed for an additional cost.
