I noticed a couple days ago my scooter is about 7 mph faster than what I'd been used to over the last week and a half since I put it together .it was getting close to the 300 mile point . It's doing a good 37, 38 mph on level road . I actually have a little bit of throttle response . I've done nothing to it . Some say it's the cooler weather ,some say it's getting broke in .it was sold as a Vittaci Viper . But the emissions plate says Jiajue . Thanks

Hi mark just wondering I needed a new piston on my Peugeot speedfight 100 , so got new pidton and barrel kit fitted it all perfectly I've been riding and that but I came back earlier today and there's oil like on the barrel and my engine gets bare hot i put overflow pipe on the carb and 2stroke in the oil tank it's air cooled don't get y it's coming out with oil and getting really hot have u any ideas mate and could help cheers .

Hi mark great video just a quick one hm do u think a garage would charge for sorting vacuum out also full carburetor service

Hi Mark, hope you've been well during lockdown! I have an nrg that bogs down if I give more than three quarters to full throttle, it gets up 28-30 pretty nicely but I used to get it going 50!! Hills are a killer also haha The variator and rollers are all clean and in good nick, carb is clean and I've got a leo vince sport exhaust, any ideas on what I can do get it back to a decent speed? Any help would be greatly appreciated, stay safe :)

Hi mark. I have a piaggio nrg mc3 purejet. When i ride it it hesitates and doesnt gain any speed When you rev it at low rpms. Only When i rev 6-7k+ rpms it works fine. What do you think it could be? It rides worse when engine is hot

Hi Mark. I've an nrg that's cutting out when it gets warm. Have cleaned air filter and the carb, tested the vacuum pump and am now onto the electrics. Any ideas what a healthy green-wire voltage should be on an nrg? I'm getting around 90v running and just around 50 when cranking. I've also tested the resistance or the green to earth which seems lowish - 90 ohms. Spark plug sparks but i am having to run it at 0.4mm to get the bike to even come close to behaving. Any ideas? Thanks for the excellent videos, they are a useful resource for people to encouragr them to have a go. Cheers

Do u know what would be wrong with a bike that seems too run fine but now seems flat like I've lost some speed and acceleration like it's gone flat what would fix it also lost full tank of fuel leaking out of carbs air intake into air box and ever since the carb was clean it just not as fast any help would be great nice videos too awesome work mate

My boys 2017 plate NRG sits comfortable in mid 50mph and touches 60mph on gps

I’ve got the same bike mate water cooled could do with some advice brand new carb keeps leaking petrol out the float chamber and it’s spitting black stuff out exhaust brand new exhaust aswel

Hi Mark, I have an NRG that is stuck at around 33 mph top speed. My local mechanic said it’s already been derestricted but I was wondering if their could be anything slowing it down still or if there is anything I can do speed it up apart from the obvious like a new exhaust or something. The moped is in good condition as well. Thanks for your time :)

My Piaggio NRG as soon as started cold can accelarate up to 70km/h when I slow down then accelarate again it only goes up to 40-50km/h and only reaches up to 7k rpm. What could be the possible problem and fix??😁

Have you done any vids of how to Derestrict

hi got the new carb are found out that is not the carb is a it was the piston with score marks down the side of it do I have to get a water cooled piston for it a or can I just put a basic piston in it

Thanks a lot!
