Hello everyone!

Hope this is the correct place for this?
ermm In a nutshell:

- I lost my bike keys two months ago and replaced all lock sets, barrels and ECU, re-coded a new key and it cost a BOMB!! certainly wont be doing that again.....

- Before all this happened I start the bike it would warm up as normal.
- now after getting it back I start the bike and after about 10 - 20 seconds in, it shoots violently up to 4000rpm until it gets to 35 degrees. and gradually comes down to running temperature.

--------

Normally these bikes go up to 2500rpm - 3000rpm when warming up...

Does anyone know the reasons for this? As now it's starting to annoy me and the neighbors :P

Any help would be greatly appreciated

Thanks!

Graham.

 

Is your coolant full? Thermostat closed when cold?

 

Yeah coolant is full and thermostat closed....

I am not too sure if its the ECU telling the bike to do it?

 

The key for me is that you said you replaced your ECU. I would start there. If you have the old one, I would throw it back on. Also, I don't know why you would need to replace your ECU for losing your keys. You should have been able to snag a ignition, cap, and trunk set and just installed it all on the bike. I didn't think the 929's were key coded to the ECU. I could be wrong though.

 

He's in the UK. His 929 has the HISS system, so the ecu and keys are coded together.
