[@retrorestore]

Cheers Nev, its a learning curve for me and I thought i'd take everybody along lol

[@killswitch_disengage]

Bought a new exhaust for mine (TGB Bullet 50), bought the Tecnigas Next-R, and now it does about 35mph with no other modifications. Didn't even remove the choke in the carburetor or re-jet it yet. I have a bunch of 21mm carbs laying about in a box, so I thought I might as well swap the carb as well as putting a pod-filter on there. Will probably get some more power in the top-end, at least I hope so. Anyway, great videos Martin, very easy to follow for someone who's never worked on a scooter before, only geared mopeds. Definitely subscribed!

[@retrorestore]

Thanks bud, glad you enjoy the vids.

I wondered about that speedo and chuckled when you banged it with your fist 😆 regarding the wart on your elbow Martin put some tea tree oil on it as I had one on my finger tried freezing it cutting it off with a Stanley blade had no joy, put Australian tea tree oil on it everyday and it was gone in a week or so.

[@haydenuk02]

Great work and thanks for sharing this with us take care

[@dodgydruid]

When you upped the cylinder, did you up the exhaust? Zorsts are tuned to the capacity of the cylinder and wondering if the exhaust is restricting as 30cc up on the capacity you should be getting more than 5-6mph. Think a Vespa 90 is a 60-65mph and the Vespa PX80 again easy for 60 mph. The exhaust dictates quite a lot in the whole "fuel pump" the engine is, if it can't expel the extra burnies quick enough it restricts the inflow so you get less angry pixies exploding and less speed.

[@retrorestore]

I removed the restrictor ring in the exhaust

[@audioorigami]

love it !!

[@dodgydruid]

Hehe I was close to 19st then I had the triple bypass... now 13st going down from a 36 inch waist to a 30 too, still got me strong arms and shoulders but can now wear M trousers which I ain't done since I was a teenager O.o

[@vdubs6068]

Great Vid Martin 👍

[@retrorestore]

Thanks 👍

[@VanlifeHQ]

Try mixing the weights mart 3.5 & the heavier ones, obviously in order like 3-7-3-7-3-7 for example I found it to be the best for top end increase to 50 mph, good video keep on going mate your get there

[@richardshomemechanics5566]

Hi Martin I’ve done a few of these Chinese scooters and I’ve found as you have no mater what you do with the rollers / clutch / belt it makes very little difference to the top end speed …the Chinese imports scooters are normally restricted via the revs via the cdi unit they work like restrictors that hgv trucks have once it hits a set speed the limiter will kick in and reduce the speed the cdi would need replacing for one without the limiter fitted or you can discount the the limiter wire ( wiring diagram needed ) this would then allow the scooter to Rev higher hence more top end ..Peugeot scooters have thus system just recently had one doing 34 mph did the cdi and if now hits 42 mph even with me on 15.5 stone ..keep up the videos they are Bob on

[@retrorestore]

I have fitted an unrestricted cdi Richard.

Was just thinking "How accurate is that speedo really?" then it started blinking lol You'd be better off with a phone in your pocket with a gps app.

[@patrik4357]

Can't remember about the exhaust, is it stock and derestricted? Otherwise, I believe the exhaust could be the bottleneck

[@allansmith7948]

Taking me back to being 16 again . And now I want to buy another moped lol . I just want that excitement of gaining 2mph and cracking the 60mph barrier 😅

[@retrorestore]

Good times lol

[@xinixxagnix201]

You have 3,5 and 7 grams, try alternately and you have approx 5 gram (GY6 engine). I am around 5,5 grams and pulls ok and speed to 70 km (60cc) with 2 shims on the variator axle cus the belt not reache all powerband without it (pulling). Sry my bad English Martin, but loved it ;p

[@lespaulplayer23]

You may possibly get a different result with a different spring now that the clutch isn't slipping. I said the red spring may have been too strong but it most likely wouldn't be working to its full potential if your clutch was slipping when you had the red spring fitted. The only spring you've really tried with the new bell housing is the white spring. Just a thought, you never know 😁👌

[@frankierutherford1888]

You could have a restriction in your exhaust. It’s definitely worth changing to a quality pipe.

[@retrorestore]

Already removed the restrictor in the exhaust

[@leejardim8429]

Hey mate, I own one of these scooters and I’ve managed to get about 45mph out of it. When I first got it the rear brake caliper was seized and the brakes rubbing was causing the speed to be restricted to about 36mph. I have the stock spring in and 8g stock rollers and the take off speed is better than a stock aerox and it still hits 41-42 mph consistently. The only modification that I’ve made to my bike is a derestricted cdi unit which I ordered off of pedparts. It’s located in the battery housing. I’m about to order a derestricted yasuni Z which should push the top speed to about 50-55mph. I weigh about 72kg so I am am a bit lighter than you hah

[@retrorestore]

I did fit an unrestricted CDI on it. I do think heavier weights will get it to 40+ like you said but i'll leave that to the new owner.

[@leejardim8429]

@@retrorestore Fair enough, in regards to one of your previous video on installing the new cylinder kit and the speed that you’re achieving I have to say that I really don’t believe that it was a 70cc cylinder as the bike stock makes almost 5bhp at certain RPMs and I’ve seen a lot of 70cc kits for this bike making close to 15bhp like the stage6 sports pro MKII

[@forevercomputing]

With your speedo, I would fit another type of speedo, GPS instead. Maybe an app or something.

[@motorcyclewild5873]

You went past my house on witham road👍👍

[@tddy-pm9cw]

Get your younger son to whizz down the road on it quick u might get them extra few mph out of it martin👌🏼👍🏼💪🏼

[@STTC]

I have to admire your determination Martin,,, great video as always,,, would you not take those high spots off the pads for a better contact? is it not just slipping?

[@retrorestore]

I don't think its high spots, I think the bellhousing was ovaled.

[@micjubba709]

Might be worth changing the coil to a orange performance one and performance cdi as tgb have rev limiters they kill the revs will ignition cut outs low at 7k or 8 a think i had one mate you won't get no more speed till change them and upjet the main in carb a couple sizes 7gram wieghts is fine lighter wieghts is just for acceleration should do about 45 mine did that was about 14 stone tho

[@crumpetcatcher]

I'd go for heavier rollers Martin. You'll easily get another 10 mph out of that and maybe more. I'd try an 8.5g, 10g and 12g if you feel like pushing the boat out.

[@paulyh4531]

Im having doubts that speedo is wrong , have you tried using your phone on gps to get a better reading of speed. Seems like that's as fast it's gonna go, which is prob good enough . Good vid. 👍

[@andyclifford5610]

Nothing ventured nothing gained mate, another good vid, can’t you get a 8st pal to ride it and see??

[@jontar1236]

I really like this video how are you

[@edwardbroomhead4463]

You want heavier rollers Martin as lighter will give better pull away but heavy will give you more top end

[@menditman2004]

Hi Martin, I’m sorry but it made me laugh when you were down to 25 mph😂 slower than my Puch 😂 I can’t get 30 mph, I think they are trying to keep us slow, just take it on the chin and enjoy the views😂. Interesting though how much difference it made. Good video 🙂👍

[@retrorestore]

😁

[@mpr106]

Here’s what I don’t get… why would changing the weights alter the top speed (rather than acceleration) when the pen trick you did before seemed to suggest you were already getting the full range of travel on both pulleys?

[@retrorestore]

Strange isn't it.

[@MrBally69]

If people or u believe it's the actual body weight of 16 stone then surely u should get someone that weighing less than 16 stone to see if u can get more than the 36mph. Good luck and ejoy the videos 👍

[@andy_v4443]

👍👍👍👍👍👍👍👍👍

[@gregsickenger3489]

New sports exhaust my 50 cc April’s sr done 30 soon as I put a sports exhaust on 45 with out new clutch spring and variator kit when I got them done it went off the clock at 50 mph that should do at least 60 with a 70 cc kit

[@adammcallister2260]

Page 52 in the book of things that didn’t happen 😂

[@crumpetcatcher]

Those SR's were quick scooters. Yours must have been left restricted of it only did 30mph. A lot of scooters are just restricted by a plate that unscrews on ten variator and removing the air recirculation bit on the exhaust. A decent pipe will definitely give more gains again.

[@Dazzy84]

[@patrik4357]

Too heavy variator weights, 7 or 7,5 grams is too much. Should be doing a lot better with about 5,5-6 grams, guessing you could hit the 40-mark quite easily with that. I have been fiddling with a great set of various chinese scooters in the past, but now I am only into Piaggio/Gilera =) Good luck, hope to see a follow-up video! Greetings from Sweden

[@retrorestore]

I tried 5.5 gram weights and didn't improve in my previous videos

[@shroomskunk]

You need a slightly bigger variator. That will increase top end speed Same as putting a bigger front sprocket on a geared bike 👍

[@retrorestore]

Great point!

[@shroomskunk]

Unfortunately most uk peds are restricted by gearing and obviously power. With a decent performance variator and clutch contra and pad springs, you’ll get 40-50mph with some patience

[@shroomskunk]

So… break it down… bigger variator for higher top speed, lighter weights to achieve a higher (power band) rpm, stiffer clutch pad springs to enable higher Rev engagement, contra will need experimenting with to cope with all these factors. Probably start on a soft contra

[@deanlanglois8185]

The standard main jet size on the tgbparts. Co. UK website that sells genuine factory parts is a size 60 I heard in the video you said it had an 85 in there it seems a lot bigger than genuine factory size have a look for yourself just search tgb x50r main jet and the tgbparts UK website comes up in the list

[@theresnobodyhere5778]

37 mpg is good for 50cc moped ,even fitting decenct exhaust will maybe up it to 40 ,ok for a 16 yr old kid ,. although they all fatter than 16 stone anyways muchen on all the fast food cheese burgers and pizza

[@paulbudford]

You could spend hours changing weights to get the perfect solution. You only really need a strong contra spring if you have much higher power, and belt slip. On to the next one Martin. 👍
