Polaris Dragon power loss

[InJapan]

I have a Polaris Dragon 2008 stock standard. Low - Mid range power supply is fine but as soon as I need 3/4 + power the engine bogs. I have changed the computer, tested the injectors, cleaned the fuel filter.

Any other suggestions please.

Make sure your compression is over 125, then go after a sticky clutch.

Thanks for the response.

The clutch has been checked and compression is ok. The power loss is substantial from hero to zero. Nearly threw my off the front of the sled when it first happened.

Ok does the power just cut out? Is it at the around the same rpm? If so you have to check out the stator, i would say the high rpm coils burnt. If the rpm just dies out slower than a light switch then there are clutching or internal problems.

Yes the power just cuts out. Yes about the same RPM each time. When you release the throttle and re-apply it the power comes back up until a similar RPM then it cuts cuts out. Where is was very noticeable was on a steep hill climb.

Test stator resistance. you can get specs from your dealer, or try RM stator i believe they have testing procedures.
