ES2 vibration

I've just done an 80 mile round trip and am convinced that the bike seems to have more vibration than normal. Not just the bars but also up through the seat/tank. I know it might just be my imagination but where's the best place to look for the cause. I've read the threads on remedies but would rather cure the cause.Cheers George

i checked my engine bolts found the two at the bottom of the engine tight well i thought they were. they were simply tightening to the angle frame rails and not clamping the engine at the same time. i put some shims down inbetween the engine and frame to solve it . the bike did seem a lot tighter after. i only found out because when i was fitting my makeshift side stand i noticed the frame rail twisting as i slowly lowered it onto the stand. all tightened up ok after and gave an overall sturdier feel to the bike and stand.

Well spotted, Barry. That was very observant of you. I haven't managed to get out to the garage today but will check you points and Richard's tomorrow. Many thanks.

Hi George

Check the head steady......Once on my M50 it worked loose and the problems you described occurred.I assume you have not altered the engine balance by a re-build?

Thanks John. I've done nothing. Just felt it was viby on the way home. The bike doesn't have a head steady so at least I know it's not that! It is sounding like something has worked loose on the retaining bolts. Lots to check tomorrow. George

Hi George. My 1957 bike is fine up to 60 MPH but gets a bit vibey above that speed. Most of the Devon roads I ride are not safe to ride above 60 so I just live with it. Strangely, when riding above 60, the speedo goes silly and wanders up to 90 MPH indicated but not plausible. It's all part of the classic bike experience.

I think you are in Cornwall. Which part, may I ask? I used to live in Liskeard.
