urgent help needed xBhpians..
bought an oct 2009 pulsar ug 4 two months ago...i immediately changed d spark plugs, engine oil (power one...not that bad), got cleaned the air filter, fuel tank and carburetor etc...however, m facing two problems...
1. the bike does not idle at all before the engine runs for at least 6 mins(in other words warms up a lot)...i think that's too long...and if i leave the bike even for one hour, i gotta warm the engine up/ride it again for 5/6 mins for it to idle...the idle setting is set for 1300...and i tried to tune the engine(by setting the idle screw at 4000 after riding 10/11 kms, then turning the a/f screw fully clockwise then slowly anti-clockwise to achieve a constant rpm)..but rpm guage does not show constant rpm..the needle remains shaky from all the way in to all the way out...that's why i kept it at 2.5 turns(the factory setting)...the mechanics in our area does not know how to tune the engine properly (hvn't tried BAS though...hv heard they are not any gud either)..that's why i had to give it a try myself
...i dont think it has a vacuum leak as it idles fine after it warms up...
2. while riding, the bike sometimes suddenly loses speed and the engine gains rpm...i gotta chop the throttle, pull the clutch in and shift the gears down up or up then down to (to remain in the same gear...or jus up or down to) gain 'throttle control'...it happens mostly in 3rd and 4th gears and sometimes in 5th as well....may be just cuz the bike remains mostly in those gears thn having any direct connection with the problem...does the fork need to be replaced??
m only a 500 km old biker and this is my first post..of course i cant fix the bike myself but i dont wanna rely completely on not-so-expert mechanics and their trial and error method..please help!!!!!
