What is the best place to buy a throttle position sensor for a GSXR600? Are there any other bikes that use the same?

Don't know if it's any help Piddy but I managed to fit a Bosch TPS to my Kawasaki throttle bodies , just needed to make an adaptor plate . Bosch item use an 8mm "D" . If yours uses a 6mm thread I have an adaptor you can have .

Cheers Rusty I'll let you know how I get on.

What was the bosch sensor off?

Got it from Emerald , £25 +vat including the connector

Same thing is about £3 from RS...

Now he tells me!!

Sorry - meant £13, but looking closer looks more like £16-20

Farnell Link- Code 7006457

Key terms to look for are "potentiometer position sense 5k"

S

RS Link - Code 319-310

Few cheap ones on fleabay e.g. 160102933852

Any luck sorting the problem Piddy? it's gone a bit quiet
