Thanks man, Appreciate it.

**Bumping up this thread**

During the last track outing, the engine seized
It has been more than 1.5 years since the moped was sitting that way as I got busy in other mundane activities.

As of Dec 22nd the bike has a new 60cc power ported heart and the plan is to build it up from there for the street. Waiting for a few essential spares and the bike will be street ready !

Re: Re-build:The Humble 1983 TVS 50 XL

Street Spec and not Track Spec???

Re: Re-build:The Humble 1983 TVS 50 XL

60cc power ported ? On the same block ? Disc brakes added ? One suggestion from me - Please change the rear shocks to the ones on RTRs.They are great for track.All the best.

Re: Re-build:The Humble 1983 TVS 50 XL

Yo man, if you put in RTR shocks at rear, ithe seat will be slanted, the rear will be high and the rear will be like R15 v2s rear (though there is no pillion seat.). But, the slanted position will give a boost on handling but stability will have a huge hit.

Hi Karthik,

Are Alloys with Tubeless Tyres (a lil fat tyres) available & possible on TVS XL.
Any upgrade to electricals possible. Mainly Headlamp dome upgrade to a larger one for more light & throw and may be adding a battery if required.
I wanted to own one as a best bike to be carried in the car's boot during the longdives/vacations to use at the stop overs as a city commuter. Pl. forgive for the Crazy idea ;-).
(Best specs ever: 70 kgs can be lifted by 2 people. 70CC, can carry 3 people if required during the stop overs. 2 carriages, 1 at the rear & 1 in the middle. Negligible maintenance)

Anything is possible mate, you just have to look at the right places and right people.

*Not sure if anyone would follow this thread, but nevertheless had to update it with some recent updates*

Alright, the TVS XL has now transformed into a TVS XXL

The previous engine conked on the Kari main straight whilst doing 110+kmph speeds. This was sometime in 2012 I believe, ever since that incident the moped has been resting whilst I was busy going through the motions of life. In Feb 2016 I decided to do take up the restoration endeavour all over again. Deja vu only !

This time, I needed a reliable set up. Done with plonking new engine cases, bore kits, porting. A radical, out of the box idea to shoehorn a four stroke engine onto the frame was concocted after a lot of 2 stroke vs 4 stroke purist debates. Once that was sorted, the most logical choice was to either buy a Chinese horizontal layout 160cc/180cc something cc motor or go for something that's easy to maintain. Enter Hero Honda Super splendour 125cc mill. It is horizontal in layout, spares should not be a problem and heck it makes 9 horses in stock form no.

Plan frozen, we and a bunch of race engineers/fabricators got into the actual build. The frame was modified to house the Honda 125cc mill. Swingarm & hub width extended. This being a geared motor unlike the old stroker motor, so we had to figure a way to shift gears and all of that. The R15 rearsets and shifter/brake levers were deployed and a frame modified to support the rearsets. Sourced a set of tachometer, odometer and voltmeter while the build was ongoing. It took a good 3-4 months to reach a point where the engine could be started. Issues with wiring the CDI and some outsourced fabrication took forever to come through. To tackle the wiring issues, we added the smallest 12v exide battery to power the cdi. The engine would start and stall after 10 -15 mins of running, as the charger circuit was not rigged up.

I had to make a visit to the Tilaknagar side wiring shops, who did a wonderful job on the wiring. The battery still powers the circuit albeit there is now charging circuit juicing the battery. Its Christmas tree when you switch on the mains.

Did a couple of quick runs and was able to manage 80s and 90kmph, this was in late 2016.

Fast forward to 2017, the bike lays dis-assembled only to get a coat of paint and decals. Pics & video to follow.

Cheers
