The 5-speed and 4-speed has a different port layout. The 5-speed has a larger exhaust port time/area over the 4-speed and also larger transfers. The 5-speed also has an additional boost port and overall the cylinder flows higher than the 4-speed.
The 5-speed barrel helps in making more higher-up power and is more desirable for a high performance build. 4-speeds have smaller ports are therefore more torquey feeling and rideable in streets. They make better low-down power over the 5-speed barrel(4TL10). Its not advisable to pimp a 4-speed(4TL00) barrel for outright power.

Longer shocks are available.
Only the amateurs do that welding job. All the pro rally guys use long travel shocks. The springs are usually yellow or red in colour and the really high end ones have the gas chamber attached.

The TVS factory shaolins pumps 28-30bhp on the dyno and are the fastest in the pack(they have the best equipment level and refinement), closely matched by pacer's Yamaha RX135.
In addition the Pacer/DTW Yamaha's winning record was way better than R&R from what I have seen and that would make them the top Yamaha tuner.

Hey Joel,

thanks for your inptuts. I previously owned a 01' model Rx-135 4-speed, I got the ports done for a rally bike. It had a slight lag once I shifted to 4th and was worse with a pillion. Do you think the regular 5-speed gearbox will cure this or should I go in for the RXK's gearbox. Thanks again as I would love to retain the same barrel for the Rxg owing to the low end torque. Having said that are there any port variations between the Rxg and the rest of the 4-speed models ??

I had Hero Honda, Shogun, Roadking and RX 100. Without any doubt, RX 100 is the best bike I ever had and like most of you regret selling it. It was a 87 model with Y 1 bore - Orignial Jap. Bought it for 25k and spent another 25k on the Mods (spent all the money Dad had kep in my bank ac) .

It is the best tuner friendly bike ever!!

Gives me lot of pleasure to share this info. Don't know its been a decade that I sold the bike, very nice memories.

Below were the mods done, and also Pic attached:

1) Navy Blue painted chasis and Silver body paint from Sarakki. He was famous in those days in Bangalore
2) 115 CC piston
3) Imported Front Mud guard
4) Straight handle with sticker
5) Box Swing arm
6) Gas shock absorbers in the rear and hightened, elongated in the front
7) Shogun indicators
8) Bucket seats - Well, Kind of!
9) Buffing and chroming Cylinder head, nuts and bolts, brake drums, Silencer
10) Yezdi headlight unit, 90/100 lighting, Yezdi rim/tires in the rear.
11) Aluminium foot rests, Headlight clamps, Chain cover
12) Bosch horns
13) Big button tires in the front with balancer
14) Ported Exhaust to increase the BHP, along with altered Muffler with steel wool...OMG..I do remember all these fine details

Longing for a RX 100 from a long time, will keep the seach on!

Saar, you might wanna check whats written on your barrel itself . 4TL10 is 5-speed and 4TL00 is 4-speed.

@mpower - DTW/Pacer took over the Yamaha team from Tectrac racing in the mid 90s. What I meant is that the R&R brothers was the only private team to come close to the TVS and Pacer Yamaha. We all know how close the TVS shaolins and RXs were. They would always play cat and mouse. Somehow TVS would mostly win the battle coz they have access to all that they want to set-up the bike.

@nitro - Its got nothing to do with the GB, its only coz the ports were a little radical for street use. The RXG and RX-4 speed barrel is the same. Once you port a barrel for high end power, you can never expect low down poke. Thats the thumb rule, unless you running a power valve. Your ignition also matters.

joel im running a ported and piped 5 speed top end on a 4 speed gearbox . i experience this HUGE drop between 3rd and 4th and i need to keep throttling the freaking bike , there is no cruise mode and it gets out of the powerband easily as the powerband kicks pretty late , only hope to overtake is cut a gear , wring throttle and hold on for dear life . i am planning on going for a 5 speed or an RXK gearbox to help me sort out this issue , i believe getting the gearing and sprocketting right would sort out this problem rite ? please advise . my options to sorting out this issue are :

1)get an RXK or a 5 speed gearbox
2)get a new barrel and port ( used mostly in city traffic - do i need a 4 speed or a 5 speed barrel ? ps: i dont have a 5 speed head )

Joel, you could be wrong. Agreed the port setup might have been radical, but a close ratio gearbox coupled with the right sprocketing should help cure the lag in between. I think it might not work only if the ports are outright mad and takes a really long time to open up.

guys, the front end is done, looks real tall and those 19" tyres look radical, will post pics once i get the rear in too as it looks very odd now with skinny rear tyre and less shock travel... expect them pics real soon..cheers.

looking at the paint scheme it was originally a 100 though i could be wrong. as far as 135 i will wait for someone more knowledgeable to spot whether it's 100 or 135. if it is indeed 135 then my guess is that he might have converted a 100 to a 135. but my hunch if it is a 100 is that he bullshitted you. but don't take my word for it!

Well, I wont take your word for it... I'll take the RC.book's, it says under displacement: 132cc..I had the same doubts as you so the dealer showed me the Rc and the pic does'nt do any justice, if you look closer you can find air bubbles under the stickers on the fuel tank which proves that it was restickered.
company ones are flawless and besides it would take a hell lot of commitment to maintain a Rx100 with the original paint and stickers for it to last 2 decades.

time to learn a little more . RXG is very similar to the RX135 with modifications to the magnet/electricals . Its got a resonator box , different magnet compared to the RX100 , different carb and its a 132cc vs the 99cc RX100 .
