A35 70cc problems

Tyler Van Wie /

Hello everyone. Been lurking for awhile but finally posting because I need help. I bought a 94 golden bullet that only sorta ran. Would start...eventually but would barely stay running. Didn't have an air filter and everything was grimy. Cleaned it up and ran the same. Bought the airsal 70cc kit, dellorto 16.16 sha carb, 70cc DMP cylinder head, spark plug, jets, and tecno estoril pipe. All installed and runs the same...what am I missing? I know it's needs tuning but won't stay running long enough to do that. Will only really stay running under full throttle. I'm attaching a link to a video of it running. Sorry it's an Instagram video...apparently I deleted the original off my phone. Thanks in advance guys.

Re: A35 70cc problems

Did you re-jet the carb? Sounds like you just slapped her on there, try a high 70's jet, maybe 78? That's probably a hair to high, but if it solves your problem, you can down jet from that point

Re: A35 70cc problems

I did throw a higher jet on. 76 I believe

Re: A35 70cc problems

Check for air leaks carb intake head cylinder should idle even if u have the wrong main jet in

Re: A35 70cc problems

I was thinking it was an air problem too. Could the intake possibly not be big enough? Will check for leaks.

This is the exact kit I got if it makes a difference. And this head.

Re: A35 70cc problems

Sounds like you need a rebuild dawg. New bearings and seals would probably make a difference.

Re: A35 70cc problems

My money is on new seals

Re: A35 70cc problems

is your throttle opening up the carb slide fully? what happens if ya shoot extra pre mix into the carb?

Re: A35 70cc problems

sounds similar to what my morini mo2 sounded like when my ignition timing was shot. I would reccomend checking the points/condensor, and check the magnets on the magneto make sure their where they should be. My issue was that the magnets being so old had come unglued so it shifted causing the poor ignition timing.

Re: A35 70cc problems

Ok - have order every gasket/seal/etc. I can find to rebuild everything as well as a flywheel puller to check points. Might look at getting rid of the points all together. Recommendations on upgrades? Looked at the za50 kit treats has but I’m not sure how it’d work on a kitted bike? Please forgive me as I know less than nothing about electronics. It’s all sorcery to me.

Re: A35 70cc problems

F Instagram, upload the video to Youtube like the rest of the world

Re: A35 70cc problems

I would upgrage to the za50 treats cdi. I use this cdi with no problems. Just narrow your problems down like this every engine needs air,gas,compression,spark to run the basic necessities.

Re: A35 70cc problems

Tyler Van Wie /

I know it has spark, compression, and carb is getting gas. Once I do the rebuild with the new gaskets I will check air.

Thoughts on this kit?

Re: A35 70cc problems

I’ve run the za50 Cdi a few times on the same bike, and have fried the coils to the point of no return once. Blew a box before that. I think that Cdi you posted is worth a try, parmakit box removes the rev limit which is the main downfall of a35 cdis anyway.

Re: A35 70cc problems

Yea the treats cdi can go bad but as long as u use a resistor plug and have good grounds it should be fine. Parts for it are really cheap.

Re: A35 70cc problems

The Iskra electrical is pretty solid, I've had little to no problem with them over the years. Points are where it's at for a bike like this. You really only should get a cdi for the timing curve, racer dude status or if you need the mega bright lights... Indian designed products made in China or Taiwan, only buy if you are in dire need of a working ignition and are poor. They will usually fail at the worst time.

kinetic's voltage regulators do cross over,

Re: A35 70cc problems

Could it be the reeds are messed up? Sounds mega-rich and is not billowing smoke, so it's probably not the seals, at least not the clutch side. If you want, you can just pull the left side cover off and see if there is any black oily liquid dripping from the seal behind the stator.

Holy shit it’s been almost a year since I’ve posted. Anyways, an update. Got the moped to fire up a few times and stay running. Bought the treats cdi plus many friends v2 with parmakit box. One of the other problems i found was that the aftermarket reed was too “strong” and was causin a blockage. Put the stock one back on and everything is fine. Still got some issues, and didn’t run it long enough to tune it, but I’ll get there later. Have a case rebuild kit that will be hopefully happening tomorrow. Plan is to redo as much of the stock components as possible (needed) since this thing obviously sat most of its life and is in bad shape. Here’s a pic of how she sits now:

Side note - does anyone know of anywhere that remanufactures golden bullet decals? Or if you have a lead on NOS ones? I want to repaint the bike but want to reuse the golden bullet decals. I have searched but all the posts I found were 5+ years old so not sure if anything has changed.

Oooooo thanks! I’ll check them out

Re: A35 70cc problems

OK - in the middle of rebuilding the case and decided to look at treats to kill time. Anyone use their stuffy crank on a kit like mine? If my crank is in bad shape (or im feeling frisky) I may grab it. Just not sure if it's too much for my setup. I need all the speed

Re: A35 70cc problems

It's never about "too much" aftermarket cranks are stronger. You may not need it, but if you want it then get it. I'd but a crisp dollar that you've had a crank seal leak this whole time but you threw multiple new parts at the bike to further complicate the diagnostic process.

Re: A35 70cc problems

Tyler Van Wie /

Yep, you’re probably right.

Re: A35 70cc problems

It's taken a year to get a tomos running? Hooolllyy shit
