I'm curious? Are you using this engine on a bicycle? Or you building it for a vintage moped? Also is the Laura M48 a belt drive engine. Thanks.
Slick old ride there!!! Thanks for sharing some pics.It's a batavus hs50. The moped is around 40 years old or so. It was given to me from a family friend and it's been sitting there for years in good shape. I got it running, drove it around for a few weeks but it was pretty slow like very slow. Kind of turned into a little hobby. Since I'm going to be replacing the crank seals and bearings I figured I would get some more speed out of it. Hence the big bore kit. https://www.treatland.tv/ProductDet...XSprune7DD44jE8SWR749EhIJaCQFRdwaAibGEALw_wcB
It is a belt drive engine which I'm also going to replace the driven sprocket from 13-11 tooth. Get a little more low end
also more pictures will help. i have a good feeling most of us aren't familiar with this engine. take pics of both sides of the case. sometimes the case can be decked other times it can't be , depending.Is there any prep work that has to be done to the mating surfaces where the gasket goes
maybe im alone here but i add a tiny amount of black rtv liquid gasket to all the seals such as these. also to the intake. i decked the intake port and also to the intake 'manifold' and just added a tiny bit of it to there and haven't had a problem. if it's an issue for other people please chime in.Of course, clean it up, make sure all the old gasket material is removed,
