These bikes are having some regular problems which were faced by mostly its every owner , problems are not very much complicated if we owns a screwdriver , and some tactics. .. . we will be discussing some problems with their solution . .. .. . .
The problem which is headache for all is its starting problem . . once we starts gettin this problem it get to your nerves , and sometimes you have to sale ur bike for this. CAUSES# major case is timining overlapp . as we know old yezdi models are based on cb point ignition .which needs to be timed properly once timing gets disturbed its difficult to attain the same but u can do it urself too. . open the right side of ur engine block of ur bike .. u will see alternator placed with a timing set on it , now open the spark plug , so that u can easily rotate the crankshaft with ur hands on cam. . .now come to alternator . there will be cam in between this alternator which opens and closes the mouth or gaps in between the points , u can rotate the cam slowly and can see how it works when the points are far beyond from each other means the the mouth is wide open throughly at this time the current is flowing through the coils and spark plug . and your piston position must be upward towards spark plug fully , u can check this by holding a small piece of any thing like long screw and slowly inserting it in the bore from spark plug hole , place the screw at the upper most position , with other hand slowly rotates the cam and check when piston comes up fully the gap between the points must be wide open if it opens when the piston is in between or dowm means ur timining is overlapping . how to adjust it. . u can see the setting screws both side of the point plate . move them close or far according to your piston situation . . if the adjusting screws are not helping ur can rotate the alternator from its holding points . . ur point faces must be wide fully whe the piston is up . . and it must closes when it came down which leds to shortcircut and current flow stops when the points faces closes . . .rune ur bike this way , it needs lots of practice but can be done with coursre of time . . . another problems willll be discussed in our next posts . .HAPPY RIDING
- STARTING PROBLEM *
Hi Gurpreet, I have modified yezdi 255 classic into cafe racer design. Now I am having problems with Spark plugs. Anytime I go for ride more than 50 km than I have to change my Spark plug ( Bajaj scooter vala) to restart my bike again. Help me resolve this sir.

Hi Vinit. Are you sure that it's the spark plug that is bothering you or something else?

DeleteHi Vinit
DeleteYou have to check the carb of your bike seems its overflowing the fuel and also check your wiring and alternator .
Hi I have a problem with my starting spark is not coming from plug. Which spare part I have to change,whetherthe small condensor next to point or the coil under the petrol tank. Can anyone reply Thanks Suju
ReplyDeleteHi Suju .
DeleteFirstly you need to check the plug , try using a new plug ,
Than go for the point settings and changing the condensor on the alternator , there are very less chances of getting the coil malfunctioned .
also check the wiring properly .
also check the magnet , getting older the magnet also loses the charge . it can be charged easily from local shops
