thee is no issue in 1st.2nd.4th gear at any rpm .
however i went to mechanic and opened the engine it were the 3rd gear teeth that were broken. besiedes tehre was some other little bearing that was also broke. these were replaced along with some other minor damaged parts. total cost 1200 mazdori... and some 1600 in parts..
damn it just a chain got dislodged and got this much loss.
for the time being i had installed qingqi 100 cc piston in stock cylinder (bored) but it is leaking pressure .. it was late night when the rebuilt completed.. will install fiber gasket as the one currently installed is cd 100 metallic one and i always have extremely bad experience with it.
