yar if it is available in 100cc and can be fitted easily that would be good as there are a lot of chinese companies say loncin zhonsheng lifan who do make 125cc horizental engines that are screw compativle with the current chassis of 70cc's.... so just remove old engine and install bigger ... yar alteration karna ka koi sai banda nai mil raha ... sab lalo panjo hain .. koi mechanic kia kahtha ha koi kia.... long and short ka mja koi aisa mechanic nai mla jo ya kar chuka ho pindi ma... kch kch kahtha hain ka karachi ma ustaad bahooth hain pindi ma iss tra ka kam koi nai kartha...
thats y i want a complete engine kit... u can google for 125 cc horizental engine for honda ....there are a lot of kits...
and i do hope i will find one because very very long time ago i saw one at a shop and they said it is to be put in cd 70 and that was 125cc ... par us time mja itna pathanai tha... that was probaby lifan...
thanks...
