To get better acceleration on my Puch Maxi, I adjusted my clutch to engage later at a higher engine speed. There isn’t much bottom end in the Airsal kit, with a heavy gear ratio it needs to build up some RPM before take-off.
I started with some stiffer springs, with as much preload as possible. Then i took about 12 gram weight of every clutch shoe. I ended up taking it down to 73 gram before i was happy with the result. I wouldn’t mind making them even lighter. Remeber to get an even weight and spring adjustment on all shoes.
I haven’t used my Puch Maxi in a long time, the aftermarket wire rims and cheap tires had a bit of vibration and the engine lacked power. I bought some Grimeca cast wheels and nice Schwalbe tires. For the tuning i got a new engine from my friend and club member Esben, don’t want to race the original number match engine.
I rebuild the spare engine with new bearings, seals and a stuffed DMP crankshaft. The topend is a 45 mm Airsal 4 port cylinder with a DMP head, the head isn’t designed correctly, i will need to make some adjusting. I started with a 15 mm Bing replica, but liked the 12 mm original square Bing more. The exhaust is a Jamarcol straight pipe, doesn’t make much noise and has pretty good performance. I need to adjust the clutch with lighter shoes and stiffer springs, there is not much bottom end in this Airsal kit.
This years moped touring took place in southern denmark, from the westcoast to the small island Langeland. To get there we had to cross southern Funen, lovely roads and nature that we have ridden through several times. Langeland was amazing too, very quiet and lots of fun roads to ride.
We experienced the worst weather we’ve ever had on our annual summer trip. But with nice shelters and warm camp fires we kept a good mood.
A small gathering of 11 members from knallertforum.dk – We met on Langeland where we rode our first trip. Later that day we took the ferry to Strynø where we stayed two nights in a lovely vacation home.
