HI Guys
I sold a used tach to a fellow and he claims that when 'the shop ' installed the tach and speedo unit, that the speedo runs good but the tach runs backward, starts at max rpm and then goes down and runs into the speedo needle. Any ideas?
Cheers

Are the drive wheels/cogs fitted the right way at the top of the gearbox?? |

Hi Spen
I never had it running I bought from aguy and he said it ran great. I sold it to this guy who has the problem. I ran it on test with a drill and got up to 2000 rpm.. no problem.
Any ideas?

Sounds like it got damaged somewhere between you testing it and it being fitted to the bike! How can it start at max rpm? Is the needle in the red when the engine is off? If it is, it is f****d! I can't see it being possible for it to suddenly jump up to max rpm and then rev backwards - sounds impossible unless the insides are useless. Sorry that this is not much help.. |

Here is the newest explination of the Tach problem.
Hi ---- FYI; just a clarification on the tach problem. The tach starts at '0' and bounces a bit; it never goes up in the rpm scale. When the speed hits about 50mph, the tach starts going backward toward the speedo needle and keeps going counterclockwise till it hits the speedo needle. Help !!! and thanks.----Dave
So what do you guys think?
Cheers,

hi
i have heard of a similar problem. In the case i have heard of the tach was off a different model than the bike it was being fitted too. I think it was a GT model tach being fitted to a model T bike. hope that helps, i'll try and find the website where i read that. |
