Hello to all, I am new here. Has anyone bought a ssr lazer 5. I bought one several weeks ago with the 70cc kit. At first I was not impressed with it. The cdi would kick in just below 7 grand and kill the performance. I put up with this for 150 miles. I than switched the rear 43 tooth sprocket to a 36 tooth and the front 12 tooth to a 14 tooth. What a difference! Before I could only go 30mph, now I can hit 50 and stay just at 8 grand. I am going to keep her at 40 mph till things get fully broke in, this all I really need anyway. Any ideas or comments? I'll keep you all up dated on its performance and such if anyone is interested. Karl |

8k is too high to run at for more than a short time, and if you happen to be running lean, the combination of high revs and lean air/fuel can lead to catastrophic failure easily (pistons damaged, valves damaged, seals blown, crank bearing ruined). Just get a non-restricted CDI (about $35) and then lower your variator weights by a gram or so, that should bring your RPMs into the proper range.

Yep, no on the 8 k! I am not approaching that now. I was considering the new CDI. As far as the variator goes, I am not sure this set up has one, just a clutch as far as I can see???

8k may be good for a two stroke I thought more rpm the better for the two strokes?

This is a 4 stroke with peddles. The two stoke guys at moped army hate them! So far since I switch the gearing I am happy. It is a china made moped, so time will tell. The motor is a Honda clone. I crunched the numbers and it is getting  plus mpg, regular fuel. I was happy to give up the oil mixing with my old two stroke moped. The only draw back is it is slow off the start, but I new that when I switch the sprockets. I still need to check into the variator.... |

I don't buy the new racing cdis they are junk in my opinion either go with a orange or casoli cdi that is if it takes the same cdi as a gy6 I'm not familiar with the pedal scoots.

Look for tvnacman's banner, John sells a great advancing angle CDI for about $35 that will prevent kick back during starting, and advance the timing angle as your rpms increase. Perfect throttle response. Oh yeah, with John's parts, you know they have been tested before he ships them!

If your rpms are reaching 8k with that 4 stroke you do not need a CDI it is not restricted if it reaches 8K. And your correct NO CVTS on the PEDAL MOPEDS they all are chain driven. Some older ones use a belt. I had one here it is: Alleyoop  |

Thanks for the info. Before I changed the sprockets out it would go up to 8k rather quickly and stop their and not go beyond no matter what and top speed would be a jerky 30mph. Now with the sprocket change the rpm goes up gradually and it cruises at 40 easily. It felt like the cdi kicked in at around 7500 . I could go faster now ![]() , but why. Anyways, Would the no rev CDI help on take off??? Now that I did the sprocket swap take off is slower, but I like the top end speed. |

Because the sprocket change you now need more power to pull the taller gearing. CDI will not help. The taller gearing is luggin the motor down it does not have the power to pull the taller gears and does not let the rpms rise quickly they slowly rise as it is gaining speed slowly.
If you do not put in a bigger BIG BORE KIT the only thing you can do is change out the sprockets do not go so tall.
Maybe leave the front at 12 but change the rear to say 40, that will help in takoffs.

I have a 2012 lazer5 72cc kit performance CSI 14 front 36 back I couldn't run the 43 back it took forever to get going so now I have a extra chain and aprocket . I have 1000 miles on bike and 40 on kit. With 14 f 36 rear I can hit 55 mph at 8 grand went to ten still 55 have to watch tach still kinda a dog taking off. Does any one know what carb mite wake it up a little more off the line? And where can I get a performance exhaust? I also have a 2012 times st stoke it smokes it until 30 mph then blazer walks away I wish blazer had auto trans. Do not shift it while moving nothing but snap rings hold gears in place I lost high gear had to split cases I replaced all rings other than that crumy design it is very cool. Hope some one responds thanks

Hey there! This is my topic, my field, lol! Sorry I'm being a bit late. I saw the cheaper Roketa version of the SSR, about half the price. The reason your motor hits the rev limiter so fast, is that the whole bike is made for a 50cc. Then equipped with a 75cc, you get 50% more power, but your sprockets aren't adjusted to it. I've been looking at turning the original 50cc into a monster MPG machine! But like you said, the bike more than likely is extremely slow, starting off, since it needs to build RPMs to get higher acceleration power. It gets around 100MPG with the original 50cc engine. One sprocket change that can be done on the 50cc, that I find of interest, is to change the front to 15t, and the rear so that the bike makes top speed in 3rd gear, and has 4th gear as an overdrive, just to attain something around 120MPG. The overdrive gear gets you between 2 and 4MPH slower than the top speed, but it's nice to brag about going cross state (like 500 miles in Florida) on a 50cc scooter, on less than $15 on gas. I don't have the ssr lazer 5, but am eyeing the Roketa mc-112-50. It has a 4 spd step through gearbox, which allows it to accelerate faster with it's 50cc, than with the ssr lazer's 75cc bbk without gearbox. The roketa is more versatile, but due to its gearbox is seen as a motorcycle, not a moped.  |
