I got 2000 miles on my 18 LTX and my friend has 2500 miles with some boosted with no problems at all. Clutches are not hot unless i'm on and off throttle a lot. Last Yami I had was a 1981 SRX and been on cats for 20 years . Was the main reason I bought a Yami was because cat had such bad luck with clutches and $200.00 belts. Thanks guys, now I'm worried about it!
