Would appreciate any info re this stuff. TIA

Reason why BJ ?

Mick Hone are great to deal with, that%u2019s where I buy all my genuine parts from and they are happy to post too.
The primary tps is on the left(when sitting on the bike) and the secondary ( stps) is on the right.
They do 2 different jobs so I wouldn%u2019t be rushing out to buy both until you fully fault find the system first.
Where are you located? I%u2019m in Melbourne and might be able to help you with some diagnosis if needed.

@grog Have read that the TPS can give correct readings but still be rooted.
Main reason I'm looking at this is I feel my bike is "sort of" surging.
Actually I was thinking of bringing it down to Landsborough so you could take if for a spin to get your opinion. Let me know if your interested. I'm on  0 four 0 three 56 four 56 0.
