Anyone know of any other cranks for the puch other than top and rito. I want to find the best quality crank as possible for my project . If not which is the best of the two ?

I always hear on here that top cranks are better than rito, but it seems like they're not too much different to me. I have an unstuffed rito, and it's fine by me. Either one is gonna be way better than stock. If you're putting a mild kit (65 metra or a polini) it probably won't matter either way. If you're throwing the 80 metra or the 80 giladori, I'd find the top crank just because I think it's better for those.
Oh, and when I say I think the top crank is better for the big kits, it's because I've never heard of or seen a top crank break (but I'm sure it's happened somewhere). I have heard of ritos breaking. So there's my logic.
There's also Metrakit cranks for Puch.

Well then I am still as confused as what I started as. How do you know if a crank is stuffed or unstuffed and which manufacturers stuff their cranks or is that a modification done by the buyer themselves?
I know rito sells unstuffed and stuffed cranks. Not sure if top sells unstuffed. It's something the manfacturer does.
You can also stuff your own crank, if the one you have has holes in the webs.
I've got holes in my webs in my rito, but no stuffing. Whats the advantage of stuffing it as opposed to leaving it with empty holes?
I just received an unstuffed Rito crank and had asked this question. Supposedly by having hte holes in the web filled, or stuffed, it reduces the volume in the lower case and increases teh compression of the fuel load. I don't think it's huge, and I'm looking for the performance gain of the cylinder, hi-comp head, new carb and clutch to give me the biggest benefits.
Treats said that the Top and Rito crank are fairly equal and that the bearings go on the Rito easier.
Well would it make since that if the bearings are a looser fit that it would allow for more play in the crank during its rotion thus potentially causing problems down the road? If this is true wouldn't the top crank be the better but harder to install choice?
The Treats method of installing bearings on a rito is to freeze the crank and heat the bearings. That way, after you install them and they cool down, they're snug. I don't think there's much room for the bearings to move, plus the engine case itself would keep them in place too if they did get wibbly.
I think the main reason it's easier to install bearings on a rito is because it has better grooves to line everything up.
