2006 ZS250GS

Oh, and on a side note i finally got in touch with someone in the Florida office at Zongshen America. Prices are very reasonable. I'm still waiting to hear back on a few prices, but it looks like i may be able to do the complete repair for around $200.

Have you removed the cylinder head? How many miles has the odometer recorded? How old is the bike?

Personally, I would remove the valves and inspect them for bent valve stems. I would also lap the valves, and replace the valve stem seals. However, if you are uncomfortable performing these tasks, and the bike is low mileage, I can understand why you might prefer to leave things as they are, especially if the valves are passing the "solvent test."

If the cylinder head is reasonably priced, I'd just replace it.

The stator is bathed in oil. Your motorcycle uses 1 quart of motor oil.

i got 3 quarts of oil out of the bike =( might have been a good thing since it sat out side for 2 years =)

Are you saying that someone intentionally overfilled it, to control corrosion during storage?

[Corvairkid]

vary possible but the guy that gave me the bike and title is not that smart he tried to take the turn signals and use them to make the head light brighter......... as well as the tail light and break light...... i fixed that with leds i used a high out put 1157 led break light and got a set of nice fo-carbon fiber red turn signals for the back and a aftermarket chines head light with leds built in for the front

Sorry for no posts in forever. I keep trying to get ahold of nestor @ Zongshen America in Florida but my emails keep going unanswered. A couple of emails a week sent out and no reply in weeks. Anyone have any suggestions. I'm at my whits end.

Thanks,

have you tried taking the head to a machine shop that specializes in heads and having them re-cut the valve sets on both the valve and head?
i've done it before on old cars

Sorry to hear about your issues.

This is the only CB I have owned that did not work out for me...

I see no reason to not bring the head to a machine shop that does bikes and see what they say.

look what i found on taobao.com http://item.taobao.com/item.htm?spm=...&cm_id=&pm_id=

I don't think Moto needs a new cylinder head, nor does he need to cut the valves seats, Kid.

Moto, you only need to clean up the support surface for the camshaft bushing. You can do it yourself, but you can also take the cylinder head to a machinist. He can inspect the cylinder head, and do any necessary work. I doubt he would charge very much.

You also need to buy a new camshaft and camshaft bearing. You can get these items from Zongshen America, or Taobao. Zonshen America is notorious for poor customer service. If you wish to get the parts from ZA, I suggest you make repeated telephone calls to them, instead of relying on emails.

You will probably get better prices, and have fewer headaches by ordering the parts from Taobao, using an agent such as TBTrends.

That's really cool, Corvairkid. Thanks for helping a fellow member.
