Correct air filter for a Lance Duke By mthomas (Read 849 times)

My bike never came with an air filter element and I figured it was time to get one as the performance should increase. Can't find anything for the Duke but found this for a Bali...does anybody know if this is correct?

Here's the airbox and filter on my vertical engine CF250 Fashion:

Since you have the same engine I'm 90% certain it would work. Rich

That is the correct air filter for your set up. There are less expensive ones out there. An example from ebay:

OK guys...I was TOTALLY wrongo. There is an element in the air box and it looks like new, clean and free flowing. All the hoses are hooked up and I cleaned the carb. It was clean as a whistle but I pulled out all the screws and sprayed with cleaner. I also cleaned both jets with wire and one was #38 and one was #110. Put the carb back in and got it started. I also checked the unreachable air/fuel screw and it was 2 1/2 turns so I put it back the same. I did not take it for a ride because it has been raining all day, maybe tomorrow. It still smelled rich to me while it was sitting there idling. What else should I be looking for if there is no performance gain.

What's it doing Mike, no top end or pick up or both? How's the plug look? Rich

[mthomas]

Really just not fast enough Rich. Only tops out at 60 or so. Has a slight hesitation when on power and exhaust smells rich.

Is the enricher extending?

Yes checked that today. I also re adjusted the valves and they were pretty close. I did tighten up the A/F screw about 1/2 a turn. The plug was black so it was definately running rich. I also took it for a short jaunt today as it is in the low 60's but seemed better. I will shake it down on a longer run soon.
