CDHPOWER 2 Stroke Gas Bicycle Engine kit YD100 CDH50mm Gas Motor Kit-Gas Motorized Bicycle YD100-CDH 79CC/80CC Engine Kit

Very disappointing cdhpower, your suppose to be zeda's rival and one of the best of the worst on these cheap China doll engines. Intake casing stripped out before I really started to snug it down, clutch arm casing same issue, exhaust port casing same too. The jugs useless and a $200 paper weight now. My dog made one of these out in the back yard.. Was my first experience with cdhpower, disgusted as "enter cuss word here pharse here" super pumped to get my hands on a yd100 finally. Going to look for a legit zeda now. Return started. You should send me another for free to save face but really doubt it would be any better

Engine only ran good for about 23 miles. And didn't run over 20mph. Bottom portion of crank doesn't always spin piston and engine doesn't have any combustion but every 4 or 5 full circles of pedaling when clutch lever release.Meaning magneto not creating spark. Internal bottom engine. The two mechanice from 2 stroke engine shops, both mechanics agree on and would cost more labor than whole kit worth.Btw. Speed carb doesn't feed enough fuel to cylinder. Had to use a different carb.Something is wrong in bottom of engine.Don't order. I've had two expert mechanics inspect. Both say. Return for refund.Waiting on seller to contact.

Very unpleased the cylindar on my YD 100was severely damaged there is over poor in the cast aluminum, so much its hideous.a cooling fin was broke completely off. There is a whole going through the cylindar. Like they were running out of aluminum. When mine was pored. I have purchased many of these bicycle motors in the past and still own and use several of the 80cc engine kits and many of the people I've built for goes through amazon for all motorized bicycle motors , kits, and accessories . i finally bit the bullet and ordered a cdh power YD 100 thinking I was getting a good motor and I m not so sure now. I was getting it to display yet another option to. Customers. You know "sale the product" I can't show this off to potential customers. I am very let down.

Package very very well came very quick on time no damage comes with upgraded G wrist pin clip the cylinder and casting look great. The first one I ordered from gasbike and the wrist pin clip broke one of the ears off and destroyed the top end .so I was happy to see clips instead of E clips. Would and will buy again. 2/23/21....Update freaking hauls azz cr80 belly pipe lightly ported 50mph on my 20" bike build. The second yd100 I have with g2 reed I hit 56mph

The kits are hit and miss... it ran for 20 seconds and the piston rings let go along with the fact that the piston was installed backwards. We will see if there customer support is any good.Update its not... I got sent a link to buy a new piston and told it would get discounted/particularly refunded making the price $10 and never got the refund so the $10 part turned into $40 and I got scammed into buying from CDH when they are cheaper options for a piston.

Well first of all they didn't send any instruction so I had to guess and how to put it together which really sucked then after I get it all together I couldn't figure the electric part out then the crank connecting bearing broke while I was trying to start it so overall it is a piece of garbage do not buy it it is a waste of money and time

ill ad pics later but someone took ther time to pack the motor vary well done i never seen gaskits so perfect everything is very clean what I never see anybody else doing I give you a gold star100% clean motor

Very happy with this purchase! Fits well, and works excellent! Recommend! :))
