its a known fact that they are tight from the factory, costing you compression and eventually causing burnt valves, usually exhaust. it will click a bit more with some gap in there but will run much better. ive seen anywhere from 4 to 7 thousands recomended. but any is better then none. |

Intake/exhaust valves in the cylinder head.

I'm with the others on tight valves. Still could be the CDI, but valves are free to check and must be done.

You may need bigger jets in the carb. I had this same exact issue with a little 70cc Chinese bike. The plug was back and gas smell exhaust, but it was running so lean that the fuel couldn't burn fully and thus, looking like it was rich. I was convinced the bike was junk then I put in a #80 jet IIRC, and it solved all the problems. I dont have a hawk (yet ;D) but an 98 jet seems small for a 230cc engine, especially if there is any buildup or restriction in the jet.
Good luck! |

She lives!!
![]() Ok so I adjusted the valves and just as everyone had said they were super tight! I set the intake at .003mm and the exhaust at .004mm. The engine sounded better but was still bogging down. Then I put on the CDI I ordered and that made the biggest change! The bogging down stopped but it didn't have much power after the 1/4 turn. I detached the air intake on the carb and she ran like a monster! So I pulled the filter and it had soaked up fuel and was restricting the air flow. I replaced it with a cheap mower filter and now she's running great. I really wish I didn't have to use a filter. Without it she runs super mean and seems to put out more torque. Anyone have suggestions for a filter that would allow more air flow? ![]() CDI https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 Carb https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 |

Still might be too tight. Others are saying that it should be .05mm intake, .08 exhaust.

I don't know about millimeters. But .03 intake, .05 exhaust should be ok. Inches, like we use in the United States.

I'm going to edit this info and suggest 0.08mm for both intake and exhaust.

I'll edit that and say 0.003" intake and exhaust, which equals 0.08mm.

To answer your question, this is my favourite filter: http://www.ebay.com/itm/42mm-Angled-...xVG6hQ&vxp=mtr

Let me correct myself. I set the valves at .003" intake and .004" exhaust.
The main jet is 110. I think I will drop it down to maybe 105 or 100. I'm still getting a bit of soot of the spark plug and around the end of the exhaust. |
