Zeda 80 tops out at 22 MPH

[Localconfusi0n]

Hi, so I finally got my bike running, turns out it was a carb issue, but it's so slow. Top speed is 22 MPH and only 13 or so going up hill. I'm running a 36 tooth sprocket, nt carb, and ngk spark plug. 40:1 mix. From everything I've seen these things can go WAY faster than mine is going. I know I'm still in the break in period but still doesn't seem like I'm getting everything this engine should be able to give.

I'm also at 6000 feet elevation, running my carb in its leanest setting. Any help or advice would be appreciated.

You need a 25 to 1 conventional mix for break in and don't try to top out during brake in. Your cab tune is probably off. Pull the spark plug and post a picture of it please.

Here's the plug

These will help you with tuning. Your plug looks rich to me

Ok, so if it's still rich at its leanest setting then I need a new jet, right?

It doesn't look super rich. Try changing your oil ratio to the proper mix and then go from there. What spark plug are you using?

Did you gap it to .025? The gap seems a little to wide and that could cause problems. Can you post some pictures of your build? We might be able to spot other issues

Go to an auto parts store and get a spark plug gap tool
