4 of 5 Top kit July 15, 2016
taco eater : jon from Birstall, United Kingdom  
Now running this kit on my '75 yam fs1e!  
Loads of work to make it fit ! But worth it pulling 70mph with more to come,  huge torque from a moped , now pulling up hills in top gear that no moped should do! Needs more gear smaller rear sprocket 75mph is next , after I sort clutch slip needs more spring,

4 of 5 total ripper HOWEVER... March 18, 2012

you should seriously consider adding the intake booster ports on the piston as well... they are on the cylinder... but not on the piston.  c'mon airsal, don't be lazy.

3 of 5 New ones are NOT Metrakits March 15, 2011
taco eater : Tom from Sacramento, CA United States  
I just ordered one of these and they are not genuine metrakit ones, I compared it side by side with one I already had and they look like good copies but have several differences.  First off it came with an arisal piston, second the "Metrakit" logo is missing from the castings, lastly the quality of the aluminum is worse than the genuine ones.  The port map looks the same so I would assume it is still a blaster but it would be nice to not sell them as metrakit cylinders.

probably the sickest metrakit part available currently.

as a matter of clarification for the part description though:

this kit will not fit on a puch e50 or za50. The kit is setup for a crank with a stroke of 40mm. the standard puch stroke is 43mm.
The other available derbi kits made for the piston port and pyramid reed motor have a 43mm stroke.
