hoppel_1984 Posted November 1, 2020 Report Share Posted November 1, 2020 Hey @ all I want to build up my engine buttom end and top end. what is your advise for my project? You all know more about the banshee than here in germany! I do not want to build a drag bike. More an MX trail version with some road use... Thougt about the Athena 392 top end but I not sure as I have read so much negative things here... Quote Link to comment Share on other sites More sharing options...
gusto Posted November 1, 2020 Report Share Posted November 1, 2020 Is your bottom end shot? If not true and weld your stock crank, they’re very stout. the driveline top end for 800 is unbeatable. You would be at 392 cc with the stock crank. What pipes and reeds do you have? Quote Link to comment Share on other sites More sharing options...
hoppel_1984 Posted November 1, 2020 Author Report Share Posted November 1, 2020 still running fine with FMF Fatty pipes and jetted 26 no TORS carbs. Quote Link to comment Share on other sites More sharing options...
gusto Posted November 1, 2020 Report Share Posted November 1, 2020 Those a great trail pipes. They usually require a bigger pilot jet like. Another option is port your cylinders Quote Link to comment Share on other sites More sharing options...
SandSlingerOR Posted November 1, 2020 Report Share Posted November 1, 2020 Driveline low port cylinders and slp or keep ur fmf pipes, vforce 4 reeds, +4 timing. That's be a fun set up. Quote Link to comment Share on other sites More sharing options...
devon1996 Posted November 1, 2020 Report Share Posted November 1, 2020 (edited) If your crank is trashed I did a HJR 4 mill crank, blaster pistons, stock cylinders, and FMF pipes and it was a good all purpose bike. No spacer plate I had a 2mm step cut into the domes on the head. Not an expensive build either I think it was less than $800 and half that was the crank. 4 mill crank and 66mm blaster pistons is 396 cc Edited November 1, 2020 by devon1996 Quote Link to comment Share on other sites More sharing options...
