My dt is gender confused and will be transitioning to a 175 imminently, last ride as a 125 before surgery, awaiting rebored barrel to return then a bit of cleaning up before fitting 
All done now with rebored 175 barrel, will be getting it175 head for it as dt one plug offset, waiting for new air filter then a road test at the weekend, easy enough to do and only need to change main jet on carb.
