Probably not an issue here, but there is an increasing number of counterfeit spark plugs on the market, and they are getting really difficult to spot.

Buying plugs, and many other items, from eBay and Amazon can be rolling the dice these days.

Legitimate dealers and established parts stores tend to be a safer option.

Agreed! I have started using the NGK Iridiums. I get them from O'reilly's. Usually only about $3 more than the regular copper. The advantage for me being that the seem slower to foul and I can clean and re-use them several times as I experiment. The regular coppers are usually done the first fouling. And the Iridiums come with a 1 year warranty. They are no brainers for me in this scenario.

I went that route then just decided its better to just get the factory plugs and get my rd running fine. Been in your shoes before, figured it out and was happy. Then it will happen again, its part of the course.

Good idea. That way I could try the right hand carbs that I have. Got a best source for that line?

You can get them from john at economycycles

Indeed they did.

If you want help, feel free to DM your phone number and maybe we can problem solve?

You may be chasing non carb related issue.

^^ yep. you can make a decent one with some scrap wood and an old ATV lift. Or FB marketplace has a HF lift that someone wants to get rid of for like 200 bucks

shit does suck, hope you seek the help and support you need.

You could use a sensor or like mark said a switch that completes a circut to turn the light on.

I have an old bullet that had an a3 engine. Upgraded to 70cc and reeds. Looks like youre running and old bi turbo pipe. They were the brand but people have switched to better pipes now

Tomos a3 a35 a55?????

Cool

probably one of my favorite sites. I use to order stuff all the time. esp when I ran mopeds before motorcycles. THEY got me into RDs and two strokes so thank you moped gods!

i have always tested with another gauge to confirm the compression.

Sausage fingers will do that. 😆

FB can be helpful. Plenty of people on there that are not part of this forum. Just do your part by giving back to the community after you learn about these bikes.

The premix can be 40:1.

The air mixture screw is quite impactful to your throttle response on that PWK. Start with 1.5 turns out from flush and adjust after it warms up. Not sure if you got the PWK with a powerjet (pretty common), but that will impact your WOT.

I currently run OKOs on my bike, which is a clone of the PWK with oil injectors.
