Title: Speedo Wobble
Post by: Sharpy on November 22, 2013, 08:35:40 AM

One thing I noticed as I pottered home last night was the amount the speedo wobble, particularly when you go over a bump... is this normal?

Cheers

Hi,
    Not with the 400/4, I would be double checking for excess movement in steering head, front forks and wheel bearings.

Okay, They were all checked for the MOT... however they will be coming off for the next stage of work so I will double check them then.

Not knowing if I was doing 50 or 60mph was, lets say... interesting!    ;D

Hi,
    Don't forget spoke and inflation checks as well, I have often seen bikes pass MOT's with minimal checks on wheel bearings etc. especially when there is no center stand to clear the wheels off the ground!

Wheels are being respoked soon so I will make sure that they are all tight at that point, and I do tyre inflation checks weekly, tend to find that about enough, unless the bike feels odd.

Bur good points.

Check the speedo cable, if there is any damage to the cable outer covering water can enter and corrode the inner cable. That causes the inner cable to be less flexable and as a consequence slows down, and speeds up as it revolves.Probably gets worse the faster the cable revolves. If there was a problem with the speedo the needle would waver at speeds a lot lower that 50 mph.

Brand new cable, however I will not write that off as the bike has been sat for a while in-between me getting the cable and getting it on the road so it may have gummed up quite a bit, they are cheap enough so I might just get another.

Hi if you mean the speedo needle pointer is jumping about rather than going up and down smoothly then it means your speedo damper pot is dry and needs refilling
