Default TGB Scooters

any other TGB owners out there - I thought there would be more than there seems to be. was I totally off base when I narrowed my choices to Kymco and TGB then deceided on TGB???

I love my new TGB 303R 50 - getting to & from work has never been so much fun

I deal with them at work and they're pretty good. The problem is that they use the Franco Morini engine instead of a Minarelli Horizontal motor.

wow - that shot right over my head, maybe I should have posted in the new members forum?

deal with them as in dealer? wrench?
it's my first scooter and I would like to get to know it better but dont know where to start. I'm don't even know how to get to inside the crunchy outer shell!

I'm thinking there's some sort of electronic governor keeping me just under 40mph - know anything about that?

Unfortunatly TGB uses the AH50L motor and not the plus. As for the restriction on your bike, you need to take it to the shop and they will be able to get you a whole new header pipe for the exhaust pipe. Instead of restricting it through the exhaust port or intake they make a small header pipe that restricts flow.

I'm not familier with the '202t 51 reg' but if it's an older model of the 303r or in between the 101 and 303 and a 2stroke 50cc there is a restrictor/limiter on the CDI that keeps the max speed down at about 31-32 (measured on my GPS). If you remove the seat box - the CDI is the black box mounted to the bottom of the frame - the brown wire is the limiter. after I cut the brown wire I max out at about 36-37. according to CobraSales that is the only restriction on the '05 TGB 50s. I believe older models have the variator spacer restriction. There is no header pipe on mine - the exhaust pipe is bolted directly to the manifold. there are expansion chamber/performance replacement pipes available for the TGB 50 - which I'm planning on installing but I want to change the rollers and rejet the carb at the same time. I'm told I can expect to approach 50mph after the upgrade, but I expect that means 50 on the speedo which will probably translate to low 40's real time. my scoot is only 6 months (800 miles) old so I'm not in any great rush to void the warranty - which these upgrades will do. BTW the CDI wire snip does not void the warranty.

I dont know about the CDI wire for sure but the header pipe is smaller than what it can be therefore restricting flow.

BeachBuzz, your scooter does have a header pipe, its the section bolted to the cylinder and then connects to the large can with 3 bolts. Also, they do make performance exhausts. I know for a fact that Tecnigas makes the Next R for it but not 100% sure on other brands.

If you dont want to spend the money for an all new pipe you can always call TGB and ask them for the larger header pipe that flows better due to the larger diameter.

brother speedy - I just went out and checked my exhaust and I'm not seeing any header or replaceable part in the pipe. there is a 2 bolt flange coming off the bottom of the cylinder, the pipe bends around, bumps up to a slightly larger section then to the transition to the can but it's all welded from the flange to the can. is it possible they did away with the replaceable part on the '05s? I'll follow up with CobraSales and see if they have any 'advice' too.

As a side note I have worked with the 150cc verson of the Laser by TGB, it is built well that I can see, and has globs of power, a good choice I would say.

Go to STOPLINKINGclick on the British flag for the English language version.
You need a 70cc cyllinder, 22mm Del Orto carb, MHR variator, expansion chamber exhaust this lot shuold give you about 80mph.

You could also get the stuff from STOPTHELINKSclick on British flag for English.
If you have questions e-mail them. The list of parts you need will be the same. I would start with the 70cc kit then the carb then the exhaust and then to use all the extra power the racing variator. You are looking at a couple of hundred bucks if you use STOPLINKINGtheir prices are lower. 70-80mph will be no problem.
See videos I have posted.

Default tgb

there is a brass shim on the variator shaft that will increase speed if removed and also cut the brown wire from the cdi ,


from another proud tgb owner


p.s by the way the tgb is the only scooter ive ever seen with a pressure fed crank to both bearings , morini engines are great if they have this sort of setup ,, bulletproof!!!

Default Just got a 303R

Hiya,

I just got a 2001 model 303R and I'll probably do a few things to help speed it up a fraction.

First of all, has anyone got a workshop manual for these things or for the motor in them? I could not seem to find one on the net.

If someone could tell me where to find the battery as well, then that would be great. The only place I've seen batteries is in fron of where your knee's are but there is no compartment there on the 303R.

The other thing I was wondering (and this is probabl most important for me) is that the odo cable is broken. Does anyone know how to get behind the odometer to replace this?

Thanks..!

Hi:I am soon to become a TGB owner. I justed traded an almost new KYMCO ZX50 for a new R9Laser. This is the 150CC version. Should increase my top speed from 40MPH with my de-restricted ZX50 from 40 to just 0ver 60 mph. Bigger wheels, biiger scooter. Hope I made the right decision!! Will take deleivery in a few days. Will let you know what I think.

I bought a TGB Delivery bike a few months ago. It is due for an oil change when I have clocked up another 50 miles. I have virtually no information in the user's manual, though - just "take it to a dealer". Can anyone recommend a good service manual for this bike?

Many thanks,

Steve

I have'nt been on provo for quite awhile ,I've been just plain busy. That being said,I want to mention,I just bought another
scooter.Its a TGB Sunset 151cc.I really like it. it has 14" tires and
it really goes.It makes my Vino 125cc look like its sitting still ,infact side by side,the vino looks like a hot-wheel toy.But when it comes right
down to facts.I would'nt trade my Vino for anything. This TGB has
to gain my respect first.My Vino has done it over and over again..

For those of you familliar with these, do you know what the pre-mix ratio would be for the gas? I'm assuming 50:1 but I'm not sure.... I'm contemplating disabling the oil injection system because it makes me nervous. I lost the top end in an ATV a couple years ago due to the injection system failing...

I purchased a TGB Key West in early June. So far, almost 800 trouble-free miles except for the headlight bulb going out on me.... I believe it was de-restricted by the place I bought it from. GPS indicates it will hit 40-41 on level ground. I'm happy with it - if I go off the odometer(which I suspect it off from actual mileage because the speedo reads on the optimistic side), I'm seeing 67-69 MPG.

If it goes 47mph, I would say it is already derestricted.

So, you're an expert...
My TGB (Sunset 50) seems to have a fuel starvation problem. If I can start it, it will idle for a while. If I try to give it gas, it smokes badly for a couple of seconds, then it dies. I assume the previous owner put a larger main jet in the carburetor. Could this be the cause ? Thanks
