Penny Clanking Around in Rear Cyl Head
that's what it sounds like, anyway. i'm assuming this is CCT failure and maybe chain jumped.
am i probably right about this??
i stopped to get gas heading home. the station wouldn't take my credit card, so i started up and got back on the street and went into the left turn lane at a busy intersection. as i was moving forward preparing to make the left, the loud clanking began suddenly. i made the left and parked and shut off the bike just past the intersection in the bus-lain (conveniently located).
i was hoping that that instrument cluster mounting bolt collar that disappeared into the bike a couple weeks earlier had finally re-appeared and found it's way into the cooling fan. i got under the bike and spun the fan. very nice and quiet.
i got down on the right side of the bike and started it with my thumb on the kill-switch. clanking is coming from rear cylinder. i killed it after about 2 seconds.
my buddy who just got a used late model Dodge pickup for free(?) wasn't answering his cellphone. he was either riding or knew why i was calling. i'd just mentioned the VTR CCT issue to him yesterday.
$155.00 tow to my garage. 5.1 miles.
i would greatly appreciate confirmation or lack thereof on my belief that it's the CCT.
also, is there a good chance that i've got some sort of valve damage already? or worse?
thanks,

Rear cylinder CCT failures are fairly rare but not unheard of. I would tear it down for inspection before I cranked it again.
On a side note: It seems that we have seen numerous CCT failures recently.

i'm not riding this week. my other bike is waiting for me to strip it down and determine what parts i need in order to fix its coolant leak.
i'm gonna order some pretty APE CCTs. i guess i'll get red ones. if i'm gonna pull the valve cover, i will install them even it the noise turns out to be something different. i hope it isn't a broken valve clanking around in there....

i really didn't want this project bike to revert to being a project project bike right now.
time i got some serious exercise, though. i need to keep two-wheelin' . so the steel-frame bicycle better become my new wheels around town.
thanks, Man.
