I wish you the best of luck fixing that darned nut. There should be a toothed lock washer in between the nut and the sprocket to keep it tight. I am suprised that it is not doing it's job.

That is something that the Chinese factories really need to learn and do.

Talking Re: Clutch cable and clutch adjusting procedures.

I am completely new to this forum, and it is the first bike motor kit I am building. I have a problem with the clutch not engaging, and the chain intermittently binding...and the manuals were TOTALLY useless, and the youtube video they linked you to was not very helpful.
I stumbled on this forum while desperatley looking at any manufacturer I could find for a better manual.
I just reading two of the threads here I think I have found the answers already! Boy do I really appreciate the wisdom and experience some of you have shared here. Hopefully in the next day or two I will be up and riding because of it.

Welcome to the forum, DWCSR!
It would be nice if you could introduce yourself in the "Introduce Yourself" thread:
Introduce Yourself - Motorized Bicycle: Engine Kit Forum
It's nice to know a little about each other, other than a screen name.

I am very glad that this forum and all of us here could help you out!
Do not hesitate to ask questions, and please feel free to use the search tab at the top of the page for answers as well. Just about everything that can go wrong with these engine kits has been asked before, and answered in more ways than I can count.
I highly recommend reading the "Classic Instructions" section:
Classic Instructions for Building and Repairing Motorized Bicycle Engine Kits - Motorized Bicycle: Engine Kit Forum
It can answer some questions and solve alot of issues before they ever become a problem for you.

I hope you enjoy this place!

Hey gearnut I will introduce myself in that forum in just a few minutes. I have built my first ever motorized bicycle and I am running into problems with the clutch engaging when there is weight on the bike. I posted a picture on "Experiences with Dax's Titan." It is a dax Super Titan on a Point Break Schwinn Beach Cruiser with hand brakes.

Default Re: Clutch cable and clutch adjusting procedures.

Your setup uses an automatic centrifugal clutch. This thread was created to help out folks with a manual clutch as found in the Chinese "HT" engines. (read up on post #1 in this thread)

That said, your clutch can be adjusted to engage at a higher or lower engine RPM by changing out the friction shoe springs for stronger ones (higher RPM engagement) or weaker springs (lower RPM engagement). I am surprised that it is giving you troubles though as DAX has matched the springs to engage at a very good RPM for most all situations.
Are you having issues while trying to accelerate from a dead stop? Have you tried pedaling to get the bike going and then throttling up the engine? Is there any oil or grease inside the clutch bell or on the friction shoes? It has to be absolutely clean and dry, free of any lubricant inside the clutch assembly friction surfaces.

GearNut I just wanted to follow up after you helped with the clutch problem. I am up and running!! I had to take another link outof the chain, not a biggie. I am going to be looking for a "running rough" thread. It sounds and feels like it is missing quite a bit, though it has not stalled out on me. And I think I am blowing out some left over fuel mixture at the muffler gasket but I am afraid to tighten it much more since I already snapped a bolt on the chain sprocket, fortunately I had one of almost identical dimensions.

Running rough. They all seem to run rough untill after the break in period.

Try running 24:1 pre-mix ratio for break in instead of the factory recommended 18:1. That tends to help out ALOT.
Switch to 32:1 after break in.

As for the exhaust leak, chances are that the mounting flange on the exhaust pipe is not exactly flat. same with the cylinder. Check them both out with a straight edge and correct the issue before over tightening the mounting hardware. If you gotta over tighten something, anything on the bike or engine, you are actually compensating for an unfound problem. Find the problem and fix it right before it snowballs into a bigger problem.
