Customer Reviews
First run was great but, after cool down checked torque on head bolts, manual said torque was 12 ft/lbs bolts broke, replaced head bolts but head leaks fuel now.
I sent the below in an email to [****] on 9/2/2024 and have yet to receive a reply.
I have installed the Pexmor 80cc bicycle engine kit per instructions but am experiencing a problem. The engine produces no spark. I have done the following to diagnose.
- I checked for spark 2 ways. By removing the plug from the engine and holding to metal ground on the engine while plugged into the coil. Also, I inserted the metal end of a screwdriver in the coil wire and held onto the metal portion of the screwdriver with my hand while touching a good ground on the engine with the same hand. I spun the engine over both times with no spark and no shock to my hand. I also tried a different new plug and no spark.
- When checking resistance between the black wire and blue wire on the magneto the reading is 324 ohms. I get the same reading on 2 different new magnetos. The black wire is properly grounded to the magneto and the magneto is properly grounded to the engine.
- Not sure how to check the CDI coil but I have tried 3 different new coils all with no spark. I did check the resistance between the black and blue wires on the coil and the reading was 550 ohms. I got this same reading on the 3 other new coils.
All spark tests performed while spinning the engine over fast enough to work.
Very good engine and the speed it has given me so far is 43 kilometers per hour.
These things are not easy to build. I wouldn’t recommend for a beginner unless you have someone by your side. If you’re up for a good challenge do it. A screw for the clutch was missing but besides that everything came with it. Piston had a little chip in it but still made good compression. You have to be careful during break in period. GO EASY, BE SAFE and have fun.
I like the build quality.
