I am looking to buy my first motorcycle. I found a good offer. A 2006 Ninja 650R with 9,700 miles for $2,500. Only problem is after I told the seller I was interested, he told me it needs a new throttle body. He said it runs fine now but cuts out when you gun it. He is replacing it for me. My question is, does this kind of repair generally lead to more expensive repairs down the road? Should I avoid this bike? Thanks to anyone who can help me.
