DASA 10mm stroker Motor rollback

[Marne 12]

Good morning all

I have a Dasa 10mm stoker motor that I would like to roll back to a stock crank configuration.
firstly...can this be done?

New sleeves, pistons and stock Crank and cases? and then machine the bottom of the Barrel?
any advice if somebody has done before .

thank you in advance
Kind regards
Marne

sell it. the work to do it and to get the port timing right is way to much

the motor is toast and need a complete rebuild anyways. Crank past the stage of rebuild so need a new one as well and just want to make it more reliable than the 10mmstroker.

Once everything is modded for the additional stroke, there is no going back , start over and maybe try to part out the DASA 10MM , someone might want the cases and the cylinders for spare parts if nothing else ..

Slap a stockstroke bigbore cylinder on it with a new crank and do whats possible to portmatch it and call it a day, yes probably little too much crank volume but nothing a regular dude will notice in the surf or boatchasing - Ever

It really depends on how it was done in the first place , does it have a 5mm stroker plate under the cylinder , if so yes you could remove it and check the port timing , it may be close , if there is no stroker plate then there is noting you can do to make it work with a stock stroke crankshaft, port timing would be way too far off to work.
