  • Restoring a RX 135 4s

    Hi All,

    I have a RX 135 4s, 2000 model. I'm planning to rebuild the machine. Need help on parts procurement and advise on the process.

    Current specifications:

    RX 135 4s 2000
    Run about 85K
    Running on 5speed bore-piston which was plonked in early 2008.
    Front & Rear sprocket (15/38).
    Front tyre 2.5x18
    Rear tyre 3.00x16 Ceat Secura

    I'm doing the restoration in steps due to Vitamin M deficiency.

    - Get the required parts for the engine & cosmetics in stages over the next 2/3 months.
    - Get the engine overhauling somewhere in Feb/Mar.
    - Get a RTR/Gladiator front fork assembly. (No disc for time being).
    - RDD CDI kit
    - RDD Head mod
    - RDD filter
    - Fiber reed valve (need help on which is good and affordable)
    - Re-wind coild to accomodate 100/90. (May consider RDD 100/90 kit in future).
    - Change both front and rear tyre. Rim size 18" on both.
    Have following in mind. Suggestions or feedbacks on these are most welcome.
    - Front
    - Dunlop ZEBRA Y PLUS
    - MRF Zapper FS
    - MRF Zapper FM

    - Rear
    - Dunlop CHALLENGER 202
    - Dunlop GEO CRUISER
    - MRF Zapper C
    - MRF Zapper Q (90/90 - 18)

    - Full body paint. Tank & Side flaps get black with white sparkles. Wheel hub, engine casing, crank casing, front fork and rear shock absrober gts matt black finish. Will try to get this done along with the engine overhauling.

    Parts procured so far from Yamaha Bangalore Wheels (Rajajinagar)
    - 1st oversize (0.25mm) piston kit at Rs. 1110/- (will also get 0.5mm as backup as its available in Bangalore showroom off the shelf)
    - Overhaul Gasket kit at Rs. 140/-
    - 5 speek chain and sprocket kit (15/38) at Rs. 459/-
    - Engine overhauling screw kit at Rs. 95/-
    - Gear lever / shift pedal at Rs. 125/-

    Parts to be procured in Dec
    - Side Panels
    - Complete bike nuts & bolts kit
    - Kicker assembly. The current one scrapes the silencer. (suggestions on which one should I go for)
    - Quick throttle
    - Mirrors pair

    I would like to know what other parts are required to be replaced when doing the engine overhaul (bearing, and parts of transmission)

    Is it good to go for a 5speed conversion kit. The reason I ask this is cause my bike feels like its reached its top speed at speed around 80. The sound the engine makes is like when you accelerate in lower gear.
    However, if I open the throttle, the bike pulls with ease till 110kmph on speedo.

    Also, I need a RXZ meter assembley. (please let me know if its available).

    Thank you for your valuable inputs & suggestions.

      First, welcome to xBhp @manarcane; pls consider posting an intro on yourself in the Who Are You section.

      This is the first step to do any restoration; have this in unlimited & then you can carry with the work, otherwise, the work is bound to get stranded in between. Without money you cannot even buy the parts, so have adequate cash before starting any work.

      Then why go for Glad's fork assy? Why not the stock Rx? This is where you need careful planning on your needs versus good to have.

      When you've all the above, you sound like you're looking for performance, when you've the performance, you WILL need front disc brakes. Looks like you need to do a serious planning or rather replanning.

      What's the current rim sizes?

      Go for stock 2.50-18 front & 2.75-18 in the rear, maximum you can change 2.75 in the front & 3.00 in the rear; and again, go for the ones with regular tread to achieve the purpose.

      You've mentioned you're lacking vitamin M, then why're you buying backups now? These are not the needs. Focus on the needs rather than good to have things, especially when you lack vitamin M.

      Did you buy this or bought long ago or planning to buy?

      Would there be a difference between this & the above engine bolt nut kit or one at the same?

      The issue is either with the frame or with the footrest rod, you need to relook at changing one of them & the scrap thing will be automatically taken care.

      Depends on what you need to change & the current condition of engine & bearings. This can be confirmed only when the casing is opened up.
      Ps - You also forgot about oil seals.

        you got a very big list brother i think when you go for the RDD options for your bike you need not look for any other upgrades in the bike my suggestion would be ride it stock with RDD goodies

          @Manarcane, you might want to save up a lil before starting any restoration.

          However a few things where you can keep for later are RDD mods. just get the RDD CDI . and dont go for any rewinding get the 90/100 kit later.

          RXZ meters are available.
          The best reeds considered for RX sized reed valve are YAMAHA YZ 125 reed petals. they are little pricey but genuine ones cost around 2200. Next come original Boyesen dual stage reeds which are for around 1900. then there are Indian made dual stage reeds which are cheaper.

          The first upgrade you should be thinking of is a disc setup. Gladiator forks are around 6500.
          Original 5 speed conversion kitS are pricey. Locally made kits are cheaper but can be noisy. if you are not looking for a better top speed, retain the original 4 sp gearbox which can save you some money too.

            Guys, help me understand, can one use Gladiator fork assy & Gladiator's front suspensions with RX100? I thought they're match only for Rx135 due to the change in top plates. I'm asking this out of my suffering!!!

                Sorry JD, I think it might be useful only for Rx135. Reason?
                1. The top part of suspension that is suitable for Rx100 is not suitable for Rx135 because of the top nuts. You know this better as I've done enough experiement & ultimately ended up buying 2 sets of new assy including suspension for Rx100 & Rx135.
                2. Last time, Sri told me the top of Rx is not compatible with bottom of Glad & he got it from a very reliable source; this means, Glad's entire setup has to be bought. Now, if Glad has 2 types just like Rx, then its good, we can probably opt to buy the older (provided they came with disc setup)

                    Thank you all for your suggestions:

                    @aargee: I've gone through the thread you have given below. Also through the restoration thread of Astro_Atul, yamdoot, yours. However, it doesn't mention anywhere whats parts would need replacement when you overhaul a engine (or precisely, what possible parts would have gone kaput and is worth a replacement).

                    With reagards to the Vitamin M, I guess I made it clear that I'm buying parts in installment. So that in the end, I only have to spend on the labour charges and the fluids.

                    Why Gladiator's fork? Once all necesary stuffs are done, I'll buy the disc setup. Till then, I can manage if I keep the brake pads in good condition. Infact, for a stock setup, they are more than adequate.

                    Current rim Size? 18" up front & 16" rear. At first, I though of going for the stock size of footwear. Then to be on safer side, I'm opting 2.75" in front and 3.00" rear. Both on 18" rim.

                    Piston Kit 1st Oversize? ART Piston, rings & Pin. Isn't this what you call a Piston Kit. And yes, Will pick up the 0.50mm kit once I'm done with rebuilding the bike.

                    Overhaul Gasket kit? Includes Crank case gasket, bore head gasket, bore gasket & silecer gaskets (the one near the bend pipe & silencer).

                    Chain Sprocket Kit is already bought. Along with other parts this month.

                    Engine Overhaul nuts? Includes all the nuts of the side cover. Doesn't include the stud nuts.

                    Other nuts & bolts which goes into other parts of the body. Most of the current ones are rusted, damaged, or are of varying sizes.

                    Kicker? Well, I have to replace this asits already damaged has bent. What do you mean by frame. Is the chassis that you are referring to. Footrest rod is good.

                    Transmission Parts? I want to know what parts would usually need to be replaced (a must) and which one's would most probably be kaput.

                    @Yamdoot How can I procure the reeds of either YZ125 the Boyesen dual stage reeds. There's not much of a price difference, so as per your suggestion, its better to go for the YZ125. Can you help me getting this.

                    @RX88 I can go for the stock RXZ disc setup and get only the lower pipes changed. But can I fit any other disc kit on it. Say, Gladiators / RTR's.

                    The next round of parts procurement will happen in the 1st week of Dec. So please help me out here?

                    I'm also considering getting the engine part done by a reputed garage and rest of the things will be done at home. I would do the engine too, but due to lack of time, its not possible. And also, its my daily commuting bike.

                      We would all be happy if it is available at the showroom. They have almost become extinct. If you know anyone who can spare a set, would be useful for quite a few on this forum.

                        ^^^ You spoke my mind Sri
                        It would be of a great help to me to avoid unnecessary expense to fix Glad's disc setup.

                          @SriramEfunds Most parts are available in Bangalore atleast. Not so sure about RXZ lower tube and disc set up. Will have to check.
                          Considering scarcity of spares, I though its better to go with RTR/Gladiators disc.

                          @aargee: I don't really require a disc now, subject to condition that I maintain the disc pad regularly which is quite difficult. Moreover, after the rebuild, I'm sure I'll require a disc and also as a safety measure.

                          I have ample amount of time. When I say Vitamin M deficiency, what I really meant is that I don't have all the money to shell out at 1 go. Which would very well be around Rs. 15000/-. But I'm in no hurry.

                          Like I said, I'm buying the parts which are required at the time of getting the engine overhauling and the associated parts. I'm okay to stretch the whole project till mid 2011. And will be shelling about 2000 to 3000 a month till then which is not so much of a trouble for me.

                          Another reason why I'm taking time is that I have a car to attend to as well. Its a Palio 1.6 GTX bought 2nd hand a year ago. Needs good coat of paint and a few accessories which will very well come close to about 35000.

                          I hope you all get my scenario here and suggest me accordingly.

                              That will be great if you could let know if it is available.

                              I think you will need to change the T-stem/suspension/fork bottom and even some mods to the wheel hub. Remember RTR wheel is slightly smaller. Do let us know what's have you decided.

                              I'm sure most of us do first hunt for the spares before they go for ONE complete restoration job. There is no harm in going slow over this project. I'm sure everyone will agree that it is not easy to get all the spares at go even one has Vitamin M. There are times where I had to wait for the parts to be available. I would also say that's the best way to approach for a restoration/rebuild project.

                              Identify what you want your bike to be like
                              Collect information with respect to what are all the parts required
                              Hunt for source of parts
                              Purchase
                              Decide a date for restoration.

                              Hope you are in the same line as above mentioned.
