A Thai guy brought me his S2r 800 with an intermittant rev counter when igntion comes on the dials somtimes move and then jam at 5000 rpm , other time it does not move at all but the bike is running perfectly ...
any ideas how i can help him as the main dealer is hopeless and 150 miles away.
also what do i need to check the TPS on this S2r800 model on my S4 and other local 996 and 916 model its all done with multimeter but the later models im not sure .....there are a lot here in pattaya now with no local service point ..I can take care of older models efi and carbies ,etc but the newer models have no support .

Can't help you much with the tach, assuming you checked the connectors and wiggling the harness doesn't help. If there are no screws on his TPS it set with diagnostic software either factory or Technoresearch VDSTS Software. You can purchase the software from http://www.ca-cycleworks.com (http://www.ca-cycleworks.com) If no one messed with the TPS it is probably fine.
Sounds like the needle is slipping on the post. You can take it apart and check for that. If it is it can be fixed with a little dab of superglue. I do mean little though just in case you need to remove them again later on.
I have had a Techno research VDST unit for the S4 and 998 it was rubbish , absolutely useless so i sold it on EBAY 2 years ago and never got paid for it a double ripoff
