Mate this is why I am asking my above question. Here is my story of how good Sirio customer service is.
At an Australian event 7-8 months ago HEAPS of Sirio WCR engines died from broken cranks. It was obvious that the WCR cranks had a serious defect. The Australian distributor "Hobby Discounter" did the correct thing and asked people to send the cranks back for replacement. This was 6 months ago at least.
Since then he has evaded all attempts to return the cranks or the motors. I have heard so many stories from both Sirio and the Oz distributor that I will not even bother to repeat them, but basically I know of at least 6 people who returned cranks only to be left with an incredibly expensive motor that cannot be used. The head of Sirio knows of this, I have emailed him MANY times. He has offered me a swap to an Evo 3 motor which is good but insists that the Oz distributor needs to provide me the motor. The Oz distributor has subsequently evaded all attempts to send me one with again a multitude of excuses. Apparently he is "doing me a favour" by fixing a manufacturing defect on this motor even thought I purchases the motor at my LHS.
I finally relented and bought myself another Evo 2 crank to fix my motor. It cost me US$90 on top of the cost of my WCR motor. Not impressed.
So in summary DO NOT BUY SIRIO MOTORS. This is a case where a company could have stepped up and easily fixed an issue, but chose not to. Now I dont know who is to blame, Sirio themselves or the Oz distributor, but frankly thats not my problem. They both know about the issue and have taken over 6 months to resolve the issue, and STILL nothing has been done about it.
I can back all of this up with a trail of emails if anybody care. Do yourself a favour and purchase a motor from a company that will fix defects.
Here is how it IS DONE. I bought a STS D3R motor. The rear bearing felt really gritty after around 4 litres of fuel so I emailed STS. They sent me a front and rear bearing and a NEW CRANK free of charge within a week. Now thats outstanding customer service.
