im not sure at the mo.....a dt engine would be the easiest option but im wanting the bike to be a speed demon so was thinking of going down the lines of a mito or rs engine. need to do loads of research to see what would be the best option but im defiantly thinkin 2 stroke.....but then again the honda cbr 125 engine is quite good (thats the one iv put in my bobber project) and im quite surprised of the power output.

Well ive decided to sell mine, its been a great bike but its time to get rid and finally get a 2 stroke lol. If anyones interested ill be putting it in the for sale section. Good look with your builds Paul.
