You didn't find anything wrong with the K-1's because there are not many in use compared to Skat, Eagle and the others........ Put more in use and you will see failures just like the rest. Most of the time it is NOT the parts fault for the failure but guys will try and put the blame there. Assembly problems, Too much NOS or just a Crappy Tune and guys will blame the parts I guarantee it! Wasn't my fault I only had my timing at 80*, I only shoved a 250 shot down its throat, what do you mean I had to change the fuel jet also?? Crap like that is what I believe goes on.
