5 of 5 Super Sick! Monday, April 8, 2024
taco eater : Urban Spaceman from Bloomington, IN United States  
Bought a 1978 Puch Maxi with this already added to it. Uses a Mikuni VM18 with a "BLACK BOSS" performance pipe. Attached to a E50. This combo lets me get about 40mph on a good day!

4 of 5 Well Made Kit Tuesday, February 20, 2024
taco eater : Phil Schaller from Cincinnati, OH United States  
The quality of this kit is outstanding. Everything went together as it should. I am on my second heat cycle and it is already quieting down. I used both gaskets, blocked the decompression hole with 6 mm studs, lapped the cylinder and head to make a good seal, running it with a 14 Bing and stock like oversized exhaust. Daily ride.

5 of 5 Awesome kit. Wednesday, August 19, 2020
taco eater : Quattro Audi from Kensington, CT United States  
Totally rips with the right setup. I hit 46mph on flat...
I'm 5'10 180..77 Puch maxi ; super stuffy crank, treats custom metrakit super street cylinder head,19mm dellorto clone carb, 86 main jet, w7 needle; Tecno boss pipe; three shoe clutch with eso springs turned 3 in from Flush. 18x45 gearing. Connecticut June 2020 weather.

Have a estoril sidebleed on it now (aug 2020), pulls harder all the way. Really woke this kit up compared to the boss. I use the endbleed with the smallest hole also.

1 of 5 Meltdown T-500 miles Sunday, July 28, 2019
taco eater : Scooter Greg from Grand Rapids, MI United States  
Ran great in the 90's heat at the Detroit rally, Monday, a cool 70 degree evening, heard a sound, like the ring going, then lost power, going downhill.....Found ring broken, and piston and cylinder with deep craters at the exhaust port.....I am thinking of buying a different kit, next time.....

5 of 5 Bobby Selby Tuesday, January 1, 2019
taco eater : Robert Selby from Baltimore, MD United States  
The ring bosses are drilled 180deg. off so there is nothing stopping them from falling out inside the piston and if you look close the nubs that hold the bosses in are 180deg off...other than that it is a great kit...

edit treats : maybe you got it somewhere else? the ones we are selling have the correct piston in them. If you did get it from us, just email and we will take care of you! EDIT: The new Metrakit pistons are actually correct and have the top dykes L ring like the "OG" kit came with...

5 of 5 1500 miles so far Thursday, June 29, 2017
taco eater : Goshen mopeds from goshen, IN United States  
And not one single hiccup. Gps'd at 50 with a mlm sha intake and a 15.15 and no case matching, with a proma pipe. 68 jet. It is a literal slap together 50mph set up. How can you give this kit less than 5 stars??? 1500 miles and still looks brand new inside. These new Metras are amazing.

1 of 5 Beware of failure....... Tuesday, November 22, 2016
taco eater : Steve Bailey from Walker, MI United States  
People on Moped Army mentioned having ring failures with this new nikasil 65. Thought I would give it a try. As warned, the upper ring locator pin failed after 210 miles. Upper piston ring came out and exploded into little pieces of hater. Destroyed the piston along with the cylinder sleeve. Bummer town.

edit treats : all of these sent from treats now include a superior piston with no issues. metra does not want to solve the problem, so we did it for you!

5 of 5 Thank GOD! Thursday, July 14, 2016
taco eater : todd amundson from los Angeles, CA United States  
So the new AIRSAL piston that comes with this works! I was scared of blow bye at first because at BDC both rings are exposed in the intake window. Still, Iv'e been blasting the crap outta this since day one.

4 of 5 potential performace, and potential failur Tuesday, May 17, 2016
taco eater : joseph dobrovolny from omaha, NE United States  
Bought a used bike with an old abused metra 65. Read on mopedarmy of some people having ring failures with this new nikasil 65. Tried it anyway. As advertised, this kit pulls really really hard paired with a 19 phbg! As warned by forums, the upper ring locator pin failed after 400 miles. I suggest trying a different piston until metra fixes this issue.
