Tank Slap - Motorcycle Forum

My D600 speedo has always shown a lot higher than the actual speed I am travelling at. I read somewhere that early D600's had 16 teeth front sprockets and Triumph offered to change them to 15 teeth FOC. As far as I know Triumph refused to correct the speedos also. I think that could be the problem with my speedo being out.

Is it possible to correct this and also the mileage will be showing a lot higher than it should I would imagine also.

Yep, the change in sprockets will cause it to read higher. And your mileage will be higher as a result.

What year bike is it?

You can change the sprockets or consider a speedo healer http://www.bikersdiscountstore.co.uk/sp ... -pl-19.php" onclick="window.open(this.href);return false; or something similar

or use this http://www.tuneecu.com" onclick="window.open(this.href);return false; and one of these http://www.ebay.co.uk/itm/Triumph-Bike- ... 27dad7fef9" onclick="window.open(this.href);return false;

Agreed. Tuneecu allows you to correct it based on a ratio.

Will tune ecu correct the mileage aswell. The bike is an 03 reg

. Sadly not.

Is there any way to correct the mileage

Correct it from now or correct it to what it should read?

To what it should read

No chance, I'm afraid. You are stuck with it.

What's the present mileage? On an 03 bike I wouldn't have thought mileage would be that big an issue if you're thinking about resale.

Bike has 48000 on it now
