- In this video I am working on the burgundy Maxi from earlier this year. Something happened and it completely shut off! I need to check for fuel, spark, and compression and figure out whats wrong with it.

really good concise video. Should help a lot of people.
Thank you! I m trying to make em simple but informative!
@@Corn-ped you're doing a good job keep it up.
Har, in DK, back in the eighties when i rode these (Not the maxi, that's a girls bike ;-), i remember us grinding down the heads, they had a full centimeter of rim on it to lower compression! On top of that the piston shown here was know as the "race piston" because the regular one had the compression rings lowered something like ½ - 1 cm below this one. Here in Denmark all mopeds (still) are restricted to 1 (one!) horsepower and 30 KM/H :-D (thanks MoooooM! ;-) )
Oof. That would be a slow ride!
Excellent video!
Thank you very much!
Old video, hope you’re still around to see this. When using a gauge to check compression, how specific is the sizing? I wanna get one but I don’t wanna make several trips finding the right size lol thanks!
It's real specific. See what size spark plug you use and get one for that size. My mopeds use a 14mm spark plug.
@@Corn-ped rad! Thanks for the quick reply.
Yeah man! Remember to hold the throttle open when you check the compression
hey bro i see all the exhaust u have hanging around.....i got one just like this one its a 1.5hp model maxi luxe 1978 model. 5/78....any way u would sell a stock exhaust?? mines rusted out right after the header pipe bend.......
Why not buy a nice new one from treatland. Tv
Good video, what did you use for a compression tester and whats the margin for error? Harbor freight c tester is usually like 40psi off of actual
I used a handy hand held one. I don't know what the tolerance is but is fairly accurate. I would use a screw in one with the throttle all the way open if I wanted to know the exact comp. This was more to illustrate that it had no compression.
Do you think the ring was defective to break like that or is this normal? Good video, thanks
I think it was just defective. It didnt have any damage, it had a clean snap. . .
My spark disappears after a few kicks in the kickstarter and it just won’t start what do I do
It disapears? I would try a new spark plug first. Check all your grounds. If a new spark plug doesnt work, and your grounds are good. Then I would test the coil.
What would of been your next step if the ring wasn’t the issue?
What carburetor is it on this one?
That was a clamp on Dellorto PHBG from Treatland.tv
@@Corn-pedwhat size?
I think this was a 19mm
@@Corn-pedThanx a lot. Love your Maxi videos 🎉🎉
Thank you!!! @@Zeljko-Lovric
