How old is your motor without being replace.
Do you ride everyday?
How often do you ride?
How many miles approximately?
How many miles do you have log on your computer?

Just wanna do survey see what one can expect.

Are you starting to realize that these engine's aren't for you?After trashing so many you'd think that would have occured to you by now!There are many folk's on here that have thousands of miles on daily drivers and engines that have given years of service.These are NOT turn key vehicles they require alot of tinkering and regular maintenance.

I have over 2000 miles on my Peugeot mountain bike (Dax F80) and it's still running good as new. I did put a Fred head on it after about 800 miles and I also decked the cylinder. I had to replace the 10 tooth engine sprocket at about 1500 miles and also put a new needle baring on it too. I don't drive it everyday, I got it about 5 years ago.

View attachment 81433 I have over 2000 miles on my Peugeot mountain bike (Dax F80) and it's still running good as new.

Did that Fred head help with anything?
From what I understand its an extra cooler head for long slow rides with weight like up steep hills.
I got one its not on, I kept the stock flat head on because it was winter needed the heat.
Now that its summer might put it on but I notice a Z4C plug stem is a little to short there is a pit in plug hole might be losing needed compression what plug number do you use if your flush?

The Fred head is a very good upgrade. First off, the large fins make it run considerably cooler, secondly, I got better compression and more power after I put it on. I did have to make my squish gap a bit smaller to get the compression boost provided by the Fred head. I got the 6cc Fred head so in order to get a compression boost you must have a squish gap of less than .06", any more than that and you won't get the compression boost that the Fred head can provide. Optimum squish gap range is .025"-.035". I tested my squish gap and found it to be .068" so I decked my cylinder down using the piece of glass and sand paper method attempting to get as close to .03" as possible. When all was said and done I picked up an extra 4-6 mph at the top end by putting on the Fred head and decking the cylinder and also got a cooler running engine which I think more significant than the extra compression for a little engine like this. I should say that you can get an imitation Fred head that will work just as well for cheaper. I use an NGK B7HS or a B8HS plug, I live in Southern CA with hot dry days at sea level so I wanted to use a cooler plug.
