lifan 125 cylinder upgrades

[stormin_norman]

does anyone know if its possible to buy a cylinder and piston kit for the lifan 125 to take it out to a 138 or 140. i can do all the work myself so it would end up cheaper than going out and buying a complete 140. any help would be much appreciated.

there is this eBay Motors: LIFAN 141cc BIG BORE KIT CRF50 XR50 SDG PRO RCM OGM (item 300022017597 end time Jan-19-08 16:45:46 PST)

but its in usa

i think if you can weight a few weeks i can supply you with one at a much better cost..

 

[edzy]

this is what i can get you

57x62mm bore and stroke
brings it too 153cc

cool, do u know if i put that on what do i do about a head. do i use the old one, put on a 140 one??

 

[stormin_norman]

just read the ebay thing, it said it was to suit lifan 138 and other 125 but didnt say lifan 125. does the kit you can get suit 125 and whats it take it out to

 

[edzy]

i think you keep the 125 head on
i will have to check

 

[stormin_norman]

has anyone else used kits like this on the lifan 125s. what head, carb mods did you make as a result of the cylinder change.

with the 153 kit you might have to bore your cases

 

[stormin_norman]

yeah 153 is a bit far to take a 125 i think, i was thinkin more 138 or 140. i didnt really wanna have to pull down the bottom end, just change the piston and cylinder... if thats possible.

ill see if i can get a smaller version
