Going very slow i know, time issues, going to fix it mechanically in phase 1 then the body in phase 2, the problem i'm facing right now is that i'm not a getting a good pick on the bike and doesn't go that much fast as well, some are saying its the tuning, but i got it tuned like 5 times still now, it was missing a lot, the mechanic installed bigger jets in the carburettor, that helped, now its not missing that much, still does a little bit, the carburettor i have at the moment is CG 125's chinnese i think, costed 1100 PKR, i think its due to the carburettor, theres no air filter installed, can't find the original one yet, the mechanic used insulation tape on the hole of the duct, half of it is taped located in the black box of the air filter. need your opinion guys, should i install the original Japanese carburettor, it's avaible for 6k in very good condition, will that solve the issue?
