I bought my 99srx new and have never had any issue with mine regarding the crank. Of the few 99's that did have problems, people were saying that a studded sled was more likely gonna have issues. Well I studded mine with 192 the first week and had it studded until approx 5000 miles. I long tracked it and now have approx 12,500 miles on it, without even an engine rebuild. Its compression is 125psi across all three without oil placed in the jugs. I always have used synthetic oils. Just a note; my sled was the last 99 that this dealer was gonna get from Yamaha. He was sold out. I might have a later production 99, not sure though, you really need to check the VIN. Enjoy your SRX you will love it.
