TGB R50X Final Testing And Changes To Variator. We try one more time to get some more speed out of the TGB scooter. Let's see if we can beat the previous 36mph we got before. We change the Contra spring and variator weights again.

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.

@richardshomemechanics5566 3 жыл бұрын

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

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.

@dodgydruid 3 жыл бұрын

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.

@leejardim8429 3 жыл бұрын

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 3 жыл бұрын

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 3 жыл бұрын

@@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

@lespaulplayer23 3 жыл бұрын

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 😁👌
