Clutch sqealing noise- what is causing and how to fix

I am having trouble with the clutch squealing. I am not sure what is causing it but I don’t want to damage anything. If it’s not the clutch than what is it. The pads look alright. Sometimes it stops for a few seconds but then starts again. It does this at all rpms

Here’s a link to the video, sorry for the terrible quality it’s all my internet would load

Re: Clutch sqealing noise- what is causing and how to fix

Does anyone know what is causing this and what I could do to fix it??

It would be much appreciated

Sounds normal its because your clutch is barely engaging at idle. Heavier clutch springs or lighten clutch shoes to get rid of noise but no harm is being done.

Even the squealing when I rev it up? Thanks for the reply

So squealing goes away when your riding right?

I can’t really hear it, but I thought maybe the engine noise was covering it up

Had a four stroke bike engine that sounded exactly like that it was brand new i removed clutch shoes and lightened them by drilling multiple 3\16 holes in them to lighten them it increased stall speed but not much but definitely quieted down. Is Diblasi still in business? Ive always loved those bikes and when i finally had the cash i couldnt contact them at their florida # . Putapipeonthebitch.....

I believe they are in business, I ordered parts from them in May. They didn’t arrive until June 17. I am trying to get it running good and then I’m considering selling it. It seems like it could turn into a money pit. Another issue I have is how much it struggles on hills, it seems like it got way extra hot and slowed down to 10-15 mph. I was hoping to use it to get to work but probably not anymore.

Re: Clutch sqealing noise- what is causing and how to fix

Sounds like the shoes and bell are polished, scuff the clutch friction surfaces a little with some 220 cloth. Also clean out the dust-crap in the clutch bell

Just saw this for some reason...

Unfortunately the ignition burned out on my diblasi and now it’s toast

Would be more than it’s worth to fix

I am probably going to sell it on CL as is

Id be into it how much?

Re: Clutch sqealing noise- what is causing and how to fix

This was never designed for long haul use, commuting etc, more like last mile transportation....they are super cool though....what kind of $ for parts? Did you look around for loose wires/grounds, could be something easy?

I agree with your statement about what they were designed for, BUT shouldn’t it last more than 280 miles??! For the expensive price they are definitely not worth it. I have looked for parts and they are very very expensive. I looked for that kind of thing and even took it to a trusted motorcycle shop and they said the ignition components were bad. Since diblasi has no resistance specifications for the individual components they couldn’t test and narrow down exactly which part was the problem. They’re only cool until they break at under 300 miles lol

Was thinking 400-500 because of the condition and low miles. Had a friend of a friend sell a similar condition running one for a lot more than that. I am looking for a solution as of now but as a last resort I’ll definitely sell. Stay tuned...

Now I have to find a reliable moped if that’s even a thing

It should, was more talking about the slow speed up hills etc, I would be terrified to drive that where I live....too small....no one would see you. And pot-holes would eat you. Still, love those things! :) Small wheels small suspension = vibration....that's why I asked about loose stuff. If you were closer I would make an offer on it.

Re: Clutch sqealing noise- what is causing and how to fix

Diblasi has a horrible and borderline dangerous steering geometry. Combine that with very small wheels and you have a death machine. The folding feature is convenient but it is too heavy to lug around so the negatives far outweigh the positives

You’re preaching to the choir, I am so frustrated with mine...

Ignition failure after under 300 miles? No thanks!

The highbeams would intermittently come on and off from bumps I totally see what you’re saying about vibration

Re: Clutch sqealing noise- what is causing and how to fix

Check through your kill switch, follow the wires for the lights, maybe something grounded out, ignition parts can be fine but will not spark if no power is making it to them. What have you got to lose?

The moped has spark and it is even blue but somehow it’s not enough to light the fuel

Re: Clutch sqealing noise- what is causing and how to fix

Check plug gap, spray some pre-mix into the cyl and see what happens, your ignition may not be bad at all? If points check timing? You may have a carb issue instead?

Thanks for the tips but I’ve tried all of that stuff, I’m not new to small engines. I tried a new plug as well. I took the moped to a trusted shop and they said exactly what I thought, weak ignition. They said either the coil or stator was bad but since diblasi doesn’t have any resistance specs, I couldn’t test either and see which part is bad.

Re: Clutch sqealing noise- what is causing and how to fix

Motorcycle shops are not always in tune with mopeds, is your exhaust clear? A blue spark should be good, I did not mean to insult your knowledge base, sorry if you took it like that. A weak spark can look good outside the cyl. You do have good fuel flow? Again just trying to help, will shut up now. :)

No no no I did not feel insulted.... I appreciate the help! I’ve tried premix down the sp hole and even starter fluid when I got frustrated. No need to “shut up” as you say I’m glad for any and all input

Edit: I did not even consider the exhaust would be plugged after only 300 miles, when it did run it seemed to run ok so I’m stuck on what it could be (edited)

Re: Clutch sqealing noise- what is causing and how to fix

I've had mud daubers completely plug my exhaust in a single day .

I kicked it over and I can feel air coming out of my exhaust. I’m worried about stripping the exhaust threads as this seems to be a common diblasi issue when it’s removed

yep belt looks like its slipping a bit under load, gently scuff and clean the surfaces on the metal clutch bell /variator pulley thing and if the belt is old replace it too it may have gotten too thin to keep good tension
