Reliable Tuner for 2-strokes in Bangalore

I moved back to B'lore 4Yrs ago & was in search of a very good, reputed, trustable & dedicated tuner for my 2-stroke collection, which includes a couple of RX135 5-Speeds, a TVS Scooty & the mighty RD350.

I met this guy back then in Sheshadripuram (Link road) & i was quite impressed with his work. He is not much of a talker, but more of result oriented kind of a guy. You need xyz in terms of performance, he will give it to you & most importantly he is not a rip off.

By far the most talented & dedicated guy i have come across for 2-strokes, not that he is not into 4-strokes, but as far as major engine mods are concerned, nothing beats a 2-stroke.

Any 2-stroke fanatic wanting to get in touch with him, request you to go through the below thread as all the work done on these two bikes are by this very gentleman.

Queries on RD350....

More queries on RD350, request the experts to comment:

1. What happens if one of the cylinders in the RD is running say STD size piston & other say 0.5mm piston? Assuming both are HT barrels & not modified in any other way.
2. What happens if one of the cylinders is LT & other is HT?
3. What happens if HT is running on LT pipes?
4. Were the sprokeing same for HT & LT?
5. What happens if one the carbs is not functioning correctly?
6. What happens if one of cylinders is siezed during running? Will the bike continue to run at half power or will it completely stall?
7. Without any mods (absolute stock) what is the approx true top speed of HT & LT. Please give realistic figures, considering the wear & tear of a 20Yr old machine & also a freshly rebuilt one.
8. Can a 90/100 W bulb be used in an RD. Has anyone done this experiment?
9. Is there any possibility to reduce the height of the bike? What is the procedure?
10. What make of 2-T oil pump was Indian RD using? Is it still available?

Waiting for some experts to reply.

Thanks.

With my limited knowledge i hope i can answer most of the ques. correctly. Please do not consider the ans. as expert opinions.

1. unless both have equal wear and tear and compression, i think it is possible.

2. with different port timings the engine wont run like it should.

3. nothing will happen. both pipes have same internals.

4. yes.

5. the affected cylinder will not perform.

6. most of the times the bike will stall instantly.

7. have seen only 140+ on the meters.

8. why not? if you have a compatible lighting kit. on points dont think it will.

9. the bike is already low. there is not much scope to lower it . maybe by an inch . else the resr wheel touches the fender or the front fender touches the monogram plate.

10. no idea. mine just says - U.S PAT.no**** .


I hope other experts here, active or in stealth mode will correct/ improvise the answers where required.

Most questions here are an RD owner's worst nightmare ...



1> Could be an issue at higher rpm due to the 0.5 mm OS piston having a bigger reciprocating mass

2> Tuning will be a nightmare coz the ignition timings (BTDC) is different for HT and LT

3> Muted Firing (No HT Roar) and maybe drop in performance at higher rpm

4> Sprocketing is the same

5> Increased fuel consumption, Drop in power and stuttering at lower rpm and maybe engine seizure ...

6> That gut wrenching groan from the engine and the bike will stop ... 5 mins later after cooling down, the bike will run like a seized engine.

7> As per the owner's manual HT=150kmph LT=130KMPH

8> Winding will be needed ... stock bulbs are 35/35W

9> Keep the RD stock ... any mods and I will hunt u down and nail u to the wall!!!

10> Will have to check ... had 2 brand new ones ... one is in my bike ... the other, like soooo amny other of my spares is misplaced somewhere in my house. No new oil pumps are available ... ur best bet is ebay USA ... us spec rds will have the same pumps i think ...

1. What happens if one of the cylinders in the RD is running say STD size piston & other say 0.5mm piston? Assuming both are HT barrels & not modified in any other way.

Un equal torsional stress on the Crank with every power stroke ( the one with the better compression will have more force on the crank ).

1. What happens if one of the cylinders is LT & other is HT?

( Same think, the low end power out put of one, will tend to push the other piston, while at the higher rpm, the other one will be dragged by the other piston, unequal power output is the bane of any twin cylinder, should never be there, matching is important )

1. What happens if HT is running on LT pipes?

( Difference in power band, though the actual difference will have to be tested to be confirmed )

1. Were the sprokeing same for HT & LT?

( not sure, but im guessing yes )

1. What happens if one the carbs is not functioning correctly?

( more stress on the other cylinder, and hence more wear )

1. What happens if one of cylinders is siezed during running? Will the bike continue to run at half power or will it completely stall?

( Depends on the extent of seizure, and the reason. people have actually run RDs with one cylinder firing, and the other open ( to save fuel ) )

1. Without any mods (absolute stock) what is the approx true top speed of HT & LT. Please give realistic figures, considering the wear & tear of a 20Yr old machine & also a freshly rebuilt one.

( As already mentioned, but a good tuned bike, with slight adjustment to timing should do 155-160 even, but it would be brand new to do that. From a rebuilt engine, expect 140-145 realistically, and 125-130 for LT.

1. Can a 90/100 W bulb be used in an RD. Has anyone done this experiment?
2. Is there any possibility to reduce the height of the bike? What is the procedure?

Smaller rear shocks, and bring the front forks up thru the steering clamp and mount clip ons. Though you will have to make recess in the tank for the clip ons not to strike.

Alternately, 17 inch rims, and slimmer profile tyres will help.

1. What make of 2-T oil pump was Indian RD using? Is it still available?

I would like to Stock spare parts for my RX100,

So Please post all the parts for RX100/135 including small parts like pin inside the carburetor, Jet etc....each and every minute parts ..............

Please help in making a list of spares to be collected...

Sanjith, most [MOST] of the parts can be sourced thru some or the oither means. You just have to trust someone to be able to source them for you. nobody is going to post the prices etc. for you cos the prices keep changing and so is the availability of spares.

yes I know all here are very helpful and ofcourse you have done a great help to source the hella light set + flosser bulb.
what Im trying to do nw is to get some parts,almost all parts including rubber parts as reserve which are available locally.

I dont need the prices, just the parts names which all are worth to stock. If any one could list them it will be of great help...
thanks in advance. .

+100

Sanjith, With regards to keeping spare parts, try sourcing the Originial Carb itself rather than searching for parts inside them which will prove useless. Original sprockets, Chain guards, Butterfly crash bars, OE Switch gears (Old Models), Speedometers, Speedo Casing with Escorts or Rajdoot on it, Engine case covers, Mandap rims, pooja nuts & bolts, OE Rectifiers, Kicker assy, Crank Assy, & Finally Bore & head. Hope this will give you an outline of what you need the most

download the below RX100 parts manual and save in your PC, will discus about critical parts in the coming days

Thanks a lot bro...

Thanks a lot Ram and Satish.........
parts catalog looks great...

@ Doc, Alok & JD, thanks a lot for your prompt response.

What i will be asking now maynot be appreciated by everyone, but being a performance oriented enthusiast, i am forced to compare a fully blown RX135 Vs. RD350 (Stock).

I have tested a couple of RD till now (both HTs in stock condition), but when i compared it in outright accelaration (say a quarter mile blast) i felt my Stage 3+ modded RX135 5-Speed was quicker. Is this just me or a 135 is actually capable of blowing away a 350 ?

Anybody who has done this please share your experience.

I am from the other end of the spectrum ... I like everything stock .

I have not had the pleasure of riding a fully modded rx135 ... but I have seen drag-race prepped RX's giving stock RDs a run for their money ... whether or not the rx can beat the rd is completely dependent on the quality of work and rider skills ...

I know the bangalore boyz are pretty good with souping up little 2 strokes into giant killers ...

Hats off to them!!!
