So last night i put in my first bbk its 72cc got her running and drove around a bit seemed great.i didn't have any plastic on though so today i put her ALL the way back together and it won't start.I did accidentally ground out the battery and adjust the valves.I'm not getting a spark i didn't blow any fuses but I'm going to double check.Is it possible that i fried the CDI?

It's possible. Go over your connections first and make sure the kill switch is set to run. If you have a spare CDI, try it. Check for AC voltage coming from the ignition wires out of the stator.

yes if the CDI is the same size should work but make sure you have AC and DC CDI units the most common is AC another way to tell what you have is the wires should have 2 sets of plugs four wires on one and two on the other if its AC and if its DC will have only one wire on the two plug

spare parts are great to have! especially electrical ones. Glad you got her running  did you have any probs with the 72cc kit installation & did you get a new head or use stock one? I am planning on upgrading my 49cc peace sports scoot to 72cc kit very soon is why i ask. |

I just used the stock head seems to work pretty well.I didn't have really any problems till i fried the CDI.Tomorrow is going to be its first real test unless it rains.I got a ebay kit for around $54 don't know if it will last but ill figure out in time. It fired right up though after build and this was my first time.

So I tried a compression test but I don't think my gauge is right or I'm not getting a good seal.It reads around 60psi but I don't even think it would crank if it was that low.There no way it's that low.
So I'm pretty happy with the performance I can get about 25 mph up pretty steep hills before it was around 15mph.i can do around 40mph pretty easy on flat ground and it hauls butt down hills. She still fires right up and there no smoking or anything like that.
I did put I racing CDI and orange coil In it didn't really notice a difference I haven't touch the carb yet don't know if I really need to.
Anyway I was wondering what y'all think about sunny scooters?

be easy on the throttle down hills! full throttle down hills can over rev the engine & cause damage to the crankshaft if i remember correctly  |
