danzley0 Posted July 13, 2011 Posted July 13, 2011 i am looking for parts to make my 125 a 250 not sure to what extent and money i have to spend to do so any help appreciated
NEV Posted July 13, 2011 Posted July 13, 2011 Study this diagram carefully Is it one of those magic eye pics?
Moderator DirtyDT Posted July 13, 2011 Moderator Posted July 13, 2011 Some 125 and 250 parts seem to be shared but there seems so little info on the 125 I think that it would be a nightmare. In an ideal world you could just buy a 250 engine and hope it bolts on. Easier than seeing if it is just the barrels, pistons and conrods that are different. I think it would be a case of surfing to see if anyone has done it and if it is a drop in I am happy to meet up and help. Not volunteering to change the barrels, too much messing about.
danzley0 Posted July 13, 2011 Author Posted July 13, 2011 as far as i can tell i think it would just mean new cylinder head and block everything else seems to be the same maybe a brake upgrade and thanks for the offer DT might take you up on that just sourcing parts and advice at the minute though

neversaydie Posted July 13, 2011 Posted July 13, 2011 In typically cautious fashion, my view is be cautious. Are you able to ride said 250 legally? You currently have a working bike, a failed project may leave you without one at all. Parts may be difficult to come by (in good order) Spend any funds available for conversion on a 250 restoration job, then have 2 bikes of flog the 125 to recoup cash. In any case, best of luck with it, let us know how you progress
neversaydie Posted July 13, 2011 Posted July 13, 2011 Study this diagram carefully I have. Hot water flowing through 4 pipes into a bigger pipe and mixing with cold water? I think I get the meaning, but whats the drawing?

Trying to swap everything on the top end will be a nightmare, timing and the like. Isn't there a nice 250 complete engine for sale? I brought a TS250 engine for under £100 the other week. Just the gaskets and stuff will probably make it cheaper to put a whole lump in.
