I can vouch for the reliability of the Yami thumpers as I had a 400 and was very reliable but.... Dont listen to 5 or 6 tards on here who get 50, 100, 150, 200 hours on stock valves and brag about it. I call them out from time to time and usually get bad gas for it. My condolences man, I hate to see this kind of stuff. Hopefully you can get it warrantied like KAS. This is what can happen with the new generation of thumpers. Great power for a price:excuseme: Good luck! I appreciate the support, but I'm not sure where you were headed with that either. My bike has 47 hours on it.
