Who dont I see more 80cc kit users are they junk or unreliable or just a lot of work to fit up. WHATS THE DEAL
80cc kits for puch 2 speed maxi mk II
Re: 80cc kits for puch 2 speed maxi mk II
the impression that I get isn't that they're poor quality, but that they require more real engine modification and care then the 65cc kits and the one speeds. Besides which, a properly tuned derestricted two speed ouch with a pipe and a 15mm intake and a 15mm bing will go 45mph with good acceleration, so why bother you know? There is one dude running exactly the set up you mentioned, I forget who . . .

ask sue .she has one on her pinto
Re: 80cc kits for puch 2 speed maxi mk II
you have to open up the mouth of the case to accept the giant sleeves on kits over 70cc, and people are reluctant to kit two-speeds that big because the tranny's are known to fail with the extra power, if you read around the advice is usually to stick to a faster small bore cylinder for a za.
Re: 80cc kits for puch 2 speed maxi mk II
that said one of my ZAs might get a kit in the spring, we'll see how it goes.
Re: 80cc kits for puch 2 speed maxi mk II
It does require a lil' bit of work to fit, but, is the balls when done.
The ped J is refering to, is Rigids '76 project. Look in the photo section, custom, Puch year 76. It is there.
Copy and paste the addy below.

There have been multiple topic on Za-50's and 80 kits in the last week or two. Use the search
Re: 80cc kits for puch 2 speed maxi mk II
Ok then you say a e50 is a 1 speed and a za 50 is a 2 speed but use a one speed to build a strong engine.But I am a big dude at 250lbs and 6'3" tall dont you think I need all the gear advantage that I can get or not???
Re: 80cc kits for puch 2 speed maxi mk II
What I'm sayn is I got a running 2 speed puch that wont carry me past 25 or 30mph topps and i only want to buy one kit because of all the other stuff i must get to make it work carb, intake ,exhaust ect. Also the kits say needs case matching and fab work. what exactly are they sayn
Re: 80cc kits for puch 2 speed maxi mk II
Well imo the 75cc metra kit isnt worth the extra money. You could get a 65cc metra kit and a tecno estoril and a 19mm delorto carb probably and be very happy.. I bet you would go 50mph with the right sprockets. I rode around at 165 lbs. and my 45 lb. dog pulling a bicycle trailer behind a stock puch e-50 1 speed for quite some time b4 finally upgrading. Metrakit 65cc for Puch is super nice quality too. I have never had a two speed. 70cc tccd is nice too, but Metra is super high quality compared though and is more conservatively timed for low end throttle response as far as I understand. My 2 kits worth.
Re: 80cc kits for puch 2 speed maxi mk II
It means you have to open up the mouth of the case to accept the sleeve as well as port match, as I said before, If you do not understand what this means yet you have much reading to do still before you kit, and stick to 70cc or smaller.
Re: 80cc kits for puch 2 speed maxi mk II
Well maciek, I do understand what it means to port match and I can do that without a problem. Maybe I should have been more specific with my question about fabricating intake and exhaust. Details are what I'm looking for. Pictures would be nice.
Re: 80cc kits for puch 2 speed maxi mk II
You need to build an intake. None of the intakes available for puchs have clearance for the large fins of the kit. Most people build them out an old exhaust tube welded to a plate that mounts onto the cylinder.
Here is one I had build it fits a Dellorto PHBG
Porting on this kit is not just about "matching" the ports on the case to the ports on the kit. You need to open up the mouth of the case to accept the larger jug of the cylinder. The case has an opening of 47mm the cylinder jugs OD is 50.5mm.
This is a photo of a case that has been opened to accept a metra.
The exhaust port is angled, a normal puch exhaust will not work and needs to be cut and welding to fit. The only pipe that is a bolt on it the Homoet 8p.
It's not that it's impossible or even really that hard to do. There are however plenty of ways to mess it up and waste a good bit of $$.
Re: 80cc kits for puch 2 speed maxi mk II
THANK YOU now thats some helpful info and its the info Im looking for tips and advice from someone who has done it before. Tell Me More about your kit adaption , is it on a 2 speed is it done or have you done many 80cc kits ect. The top pic looks like a pipe welded to the jug i know its not but do you have a better pic?
Re: 80cc kits for puch 2 speed maxi mk II
I have a metra on my e and it's not even broken in yet and it goes 50. What's my secret? My carbs only 15mm and my airbox is stock. That means the velocity of the air stream entering the chamber is greater on the intake, and that there's significant ba do pressure on the way to the compression stroke to keep me from losing any of that air/fuel charge whilethe ports are still open. Inmo, high-flo filters and big carbs do more harm than good when you're trying to compress such a teensy weensy charge of gas and air. You'd have to be going full throttle for two or three blocks before hi-flo characteristics would help your top speed
