Any info on a Hawk 250 dirt bike.
Just bought this Hawk 250 dirt bike in Arlington Texas and wanted to get more information about it. The bike is from the Chongqing Haosen manufacturing company and has a 167FMM 223CC engine. Is this manufacturer known for quality products, I found very little information about them? Are all of the 223cc Honda clone engines basically the same except for the side covers? I had the retailer replace the oil with synthetic oil and drove the 50 miles home then replaced the oil again. I found very little debris in the oil screen and the used oil was dark but nothing I did not expect. I put another 100 road miles on it the next day plus 5 off-road hill and sand miles. So far the only issue I have with the bike is it only will do 50 MPH and acts like it is starving for fuel or has a rev limiter kicking in. Lower speed but hard acceleration will also exhibit the same behavior. If the manual is to be believed the bike should do 60 MPH. I have not run it with the fuel cap removed to verify proper tank venting yet but wanted to hear other ideas of what I could check the next time I take it out. Thanks for your help.

Nice looking bike! What year is it? It looks very much like my TMEC 200 enduro, but I am quite sure they are unrelated.

I would suspect the carb is very lean from the factory. The other issue may be a giant rear sprocket.
Welcome. Have not seen that bike before.

I don't know if you are a 'newbie' or not, but the choke lever on the carb should be all the way down. There are mornings, when the weather is cool (and when I first got my bike), I put the lever to half way to get her started and warming up, get the bike loaded with my lunch and such, start riding, and hit some nasty dead spots, and realize I had not put the choke back down. The ironic thing is, I wasn't even a newbie to my bike, a TMEC 200, since I had just owned an older model and should have known better!!
If that is not the case, it sounds like your bike could use some carb timing. As well, these bikes often come with awfully big rear sprockets which should be changed out, pronto. Most likely, you have a wheel which is a clone of a '80 Honda XR185 which makes sprocket shopping quite easy (and low cost!!). Moderator 'Weldandgrind' has links to a continuous ebay seller who has Chinese Mikuni carbs...the advantage of changing out your carb to a Mikuni is the fact that the jets can be purchased most anywhere, whereas your stock carb is probably the decent (decent most of the time) Kiehen carb (which states PZ30 on it, and 'Standard of Japan') These are decent as stock carbs (I have not yet upgraded mine in the 4200 miles I have commuted on mine since the end of May) but their jets cannot be changed. Stock, the bike should be able to hit 60 mph, and with a rear sprocket change, it should be able to maintain (cruise at) 60 or up to 65 without sounding like the engine is screaming for mercy.

How did you determine the engine is 223?

223cc is incorrect I should have stated that it is a 229cc engine which is printed on the emission control tag on the engine.
