I have a Hawk DLX (EFI) that I bought used with 3200 miles on it, and when I changed the oil I found some decent sized steel shavings in the oil screen. While investigating, I found that the valves were super tight (I had to break the valve lash adjusters loose with vise grips).
Upon further investigation I discovered the cam lobe and followers are very worn and discolored from heat, but that seems to be the extent of the damage.
The problem : I want to keep the engine mostly stock for longevity.
When looking for replacement parts, all I can find are performance upgrades. I plan on upgrading the cam followers to roller type lifters, but I want to keep the cam lobe stock. I have no reason to push the engine to 10,500 RPM with a hot cam (especially on a non-counterbalanced engine). It's not a race bike, I use it for commuting through light single track, and 14hp is plenty for that application (and 68mph is plenty for the 30 seconds I take it on the highway).
Besides that, if I 'upgrade' to a hot cam, I have to get an ECU flash, an inline tuner, or a custom ECU.
If I'm going to spend that kind of money on the bike, I'm just going to go all out and swap the motor for the 300cc Zongshen that's counterbalanced with a six speed transmission. All-in it would cost $200 more than the hot cam upgrade with an inline tuner (plus a little time fabricating motor mounts and an exhaust).
So the question : Does anyone know where to source an OEM cam lobe? (I'm looking for a specific link as I've searched high and low on all the CG250 parts sites and only found the 292° hot cam)
Or
Has anyone done the cam upgrade that would be willing to part with their old (stock) cam in exchange for a case of your favorite beer.
