What the price of zic 4T? Is it better than Havoline?
Second thing is that my 70 starts vibrating and making sound so much if the speed is 50+.the vibration is so much that its difficult to put feet on the foot rest.
The vibration might be due to rim fault. If you hit a bump at fast speed the rim would have lost its fair round shape.
I also thought this at the next tuning i will have the rims fixed.
irst tight all the nuts and bolts also the centre axial,,next tru ur roims, use proper ai pressure in ur tyreadjust tappets in a proper way,,lubricate ur chain properly
Don.t ever use ZIC.. Havoline is best for Bikes.
ZIC is good for cars only. I used once in my bike and the engine feel was completely different, not good at all, to put in plain words.
It could be one of the following resons causing the vibration.
1: Are engine Bolts all tight? Check and retorque them if necessary.2: Swing Arm bushes in spec? check for axle looseness and if the axle has any play in it then the bushes will be replaced.3: Even a slight misalligned/damaged magneto can cause severe vibrations that is felt at foot rests.
@posterSame was the problem with my hero 2011.Believe me iv'e tried everything but it just doesn't go away .As a last resort i added extra washels to the engine mounts.It still vibrates but considerably less than before.
