A few years ago I had an F4 for only a couple years. Never had it long enough to experience any maintenance issues. Had quite a bit of money put into it and nearlly gave it away. Needed quick cash and had to sell it due to a house I bought needed some work and regretted selling it ever since. Only thing is that I could never get the low end torque or power that I wanted from it. Now I found a 99' SuperHawk at a dealer for $2750 ( they were asking $3299) and I know $2750 sounds high but it is super clean, with just over 16,000mi. Now I've had other bikes and I've laid bikes down before and usually there are some kind of tell tail signs if a bikes been down, but this bike doesn't have a scratch on it. It's all stock, exhaust, blinkers, and windshield, everything. The service guy there said it was his bike after an older guy traded it in for a sport / touring bike. The service guy said he had it for a year and once he started riding it the cct broke, ( cam chain tentioner) and bent two valves. He fixed everything and decided to sell it, now that's where I come in. I dont know much of the lingo when it comes to this, but I see cct, rs, or ss, I dont know what ever it is can some of you guys fill me in. I guess my main concern is that what are some common problems with SuperHawks ( like the cct's) that may go wrong, and is there anything I can replace before it brakes, so it doesn't cost me more $$$$$ when it does brake? Thanks for any help.
