Bike laggs, only at WOT, rpm not an issue.

[Quelish]

My best mate's bike, a 95 r1100. I can be at redline, everything fine, as long as the speed is low and throttle is not opened all the way. Once I get around 75mph or so, the bike doesn't want to go faster unless I roll the throttle on slowly, and never touching WOT. No matter what speed I'm going, or RPM, WOT makes the bike act a bit sick.

Here's the thing- the dealer adjusted the TPS, saying that it wasn't proper like. Previous owner changed it or something. It was after they moved it that I've been having problems. New plugs, new coil, new wires, new head gasket (some carbon buildup, but doesn't make the pinging sound, just loses power), new fuel filter. I'm thinking that the TPS is not right, not synced proper with the throttle.

If it's not, how do I make sure that it is? When the did the TPS, they also did a throttle body sync and they adjusted the wires and whotnot.

Cheers!

Wot exactly is WOT?

Wide open throttle... I use the term WFO..

wide open throttle...

Yeah, I realised that just after I clicked 'submit'.

I don't understand the terminology though. I thought the throttle was like a switch - either open or closed.

Thats when broadband is not your friend...

wide open throttle. Been on too many American boards. I discovered after riding my mates bike that there actually is a setting between open and closed... Who knew.

But back to the issue, any advise on the throttle position sensor? Or something I missed?

Whip the plugs out after a run at WOT & see what they read ? Air filter clean ?
