Only 1900 on the bike no other problems, center stand added, header pipe added, after market kick stand, and Sergeant seat added. 4,000.00.
Those are shrinkage lines from the casting process. Very common in all kinds of cast aluminum products.

Pro Cycle/Warp 9 chain guide issues

Anyone try one of these from Pro-Cycle? I am having the chain rub on it with the supplied hardware.

Not to be a a prick about it,but if are you worried about the casting marks sell it and if you are lucky you may find something with out marks.Various reply's that it's no big deal.My 97 has them and I ride the crap out of it with 0 problems.

I bought a chain guide from Kientech and I had to shim it with a couple of washer to center the chain on the blocks.No big deal,works just fine.

If it has the metal base gasket, offer $2500. If it has the paper base gasket, stick to NADA value.

Actually, I believe those are mold crack lines. After a mold is used a 1000 times for making a part it gets small heat cracks in it (especially in pressure molds and forging dies). After it cracks the alumn. fills in the cracks and you get what you see there.

My understanding of a shrink line is where one part of the mold cools quicker- shrinking faster then another which causes a parting line (also known as a shrink line). This type of line often leads to a crack because of stresses in the metal.

Edit: They are probably using the same mold from 1996! LOL

Thanks for help just sent e mail there isn't much else that would fit as its for ccm 644 which has dr 650 engine in british built frame and white power suspension brembo brakes etc sort of like ktm but with engine you don't have to rebuild every 10 mins

Ahh! That makes perfect sense. That would explain why we don't see them on everything and they seem to show up on these things that are probably using 25 year old molds.

Anybody got photos to compare these marks? Do the cases all come out of the same cracked dies?

we'll just call them old age lines, old age veins or old age beauty marks.
