Default Re: Got gifted a Yamaha RD350 - Restoration in progress

you are right about today's bikes, most of the people who exchanged their 2 strokes for 4jokes are now regretting, some people don't get the 2stroke scene or for that matter the restoration scene at all, I have seen, old scooters being restored, a cd 100 restoration is a common sight and all they get is 5k max for a fully restored cd 100. I have seen max 100s and ax 100s getting restored as well. But when someone can't afford a rx series bike they go behind suzukis, the scene is chaotic. But it will also mean availability of parts, a lot of forgotten bikes now get to live a second lease.

People are really ignorant, no rd build happens at a budget, those two words never go in one single sentence. But I got mine done without any compromise, the usual modus operandi is to get a bakra sell him a bike from their shop which is a work in progress, tell the guy the owner is abroad and usually wires the mech money and waits for his turn. The over excited customer who has never seen so many RDs in the real life at one place falls prey and buys the bike in the dream of riding it and finally a point comes when the customer pulls the plug.

When people hear that I did the build myself, nobody believes and the ones who believe me have difficulty accepting the fact that Monday to Friday 8:30 to 6:30 I do a white collar job. It's this so called "hype" that makes an RD build so difficult. Anybody with the right attitude and passion can do it, it's not like your regular 9-6 job, sometimes your drawing room turns into a garage, like juggu mentioned some pages back, you end up sleeping in your hallway. But all that becomes a reward once you ride your creation. Once people stop you to ask you more about the bike, once mechanics chase you and when you park your bike silently admire it. That's the actual reward.

Enough of gyan, now it's time to enjoy the bike. The tachometer is not working and the speedo shows a max of 40km/h, what a royal way to run her in

Wow those were some great experiences shared here.RD350 is a very simple machine less complex than the Splendour but the hype created is the necessity of the mechanics just to skim as much as possible.
My restoration is also being done at home, let's see where I reach.
I saw a Yamaha DT125 tacho, if its used, the need for pilot lamps is eliminated, do check it

Check my earlier post, nothing goes unattended before I crash for the day. The tachometer cable snapped, replaced it. Without any doubt it's the single most fiddly job on the RD took me about an hour to put the v boot back. I am sure there must be a simpler way. The tachometer will be replaced, but at a later stage, for now this has to work.

Technically phase one of the build is over, now small tinkering will start. I have to get the fuel filter replaced in my 100. Tomorrow is going to be a free day.

PS: I am open to ideas to take care of the rust forever. Presently I have put couple of msgnets in the tank.

Changing the RPM cable had greatly helped the dancing tacho to stop dancing , the cable snapped last Saturday, noticed it not to be dancing yesterday.

Small write-up for the Allied CDI, the CDI is good for street applications. bike starts in the first kick. goes till 100 without any effort once the engine reaches temperature, there was a slight missing after 100, could be due to the fact that the engine is freshly built. I have completed around 400 odd kms. There is a prominent piston slap since the last 200 odd kms, hoping it would reduce, it is mainly from the left cylinder. Back to sane riding till the 1000 km mark, might change the speedo this weekend, the one present is not that accurate, might shoehorn the avenger speedo since the worm is from an avenger.

In other news, my 100 is causing a lot of heart ache lately. Its idle is surging, has rust issues inside the tank. I just spent a good 10k on paper work recently, so have to hold the cash flow to the 100 for a while. I am thinking of a new tank and a new carb, the old one had a glorious life till now.

Its better you buy the New Set of Speedo & Tacho which has the same setup as the new ones for other bikes, stable needles & accurate.i have seen such setups available.
My feeling is that one should have proper readings during RUN ins.
Other way would be retro fit an RX speedo in the RD casing, i might try it.
OT: My Engine tear-down is complete.
Any idea how to remove the Headlamp Holders(ears) from the Fork without disturbing the setup much?

Pramod, I would advise you keep your adrenalin levels low till you complete 1000kms in the odo. 400 kms of run-in and 100kmph might be too much stress on the fresh engine.
Try epoxy coating inside the tank. It can protect from rust & also seal tiny holes if any. Rust was a menace in my Vijai Super. Every 3 months I had to drain all fuel, rinse the tank & clean the carb from rust deposits. Got epoxy coating done, and riding it peacefully since 2 years. Beware of buying new carbs. Do some homework to save yourselves against fake / look-alikes. If the current carb setup doesn't leak or flood, you may stick to it at least until the engine runs in.

The new meters you get these days for RD are hideous, the quality is really pathetic, I have seen those on high cost builds. I am planning a pulsar/Avenger setup cause the cable is custom made and I don't feel its right to have a custom one made every time it snaps. The avenger rim size is 17" so will have some bit of speedo error, hence I would be wise to go for the pulsar setup.

Rx speedos available these days are not intended for heavy use, they tend to go wrong easily, the effort required to fix it in the RD console is not worth it

Put some generous amount of WD 40 and use a mallet to slightly tap on the side and underneath. If you don't have a mallet, use your hands and rock it side ways once they become little free, yank them up. If you are having such trouble getting them out you will have to increase their size when you go for any disk brake setup. You might have to make the Headlight Stay little wider, that can be done by taking the new forks with the inner tube to a denter and ask him to make them fit, let me know if you need any help with choosing the right setup.

It was a small blip for 100 mts, once the engine reaches temperature minor blips are fine, what gets you is prolonged WOT.

I need more details on the epoxy coating, please tell me more about the process. How many days does it take for the paint to cure, any special preparation.

Now only seeing this thread. Great work Pramodkumar! The color of the bike is very cool. Is it going to be a weekend runner?

With thanks and regards

Epoxy is a 2 part solution - a resin & a hardener. A very commonly seen example of epoxy based glue is Araldite. Yamaha Motors themselves sold a product called RR10. Don't think it is still available in showrooms nowadays. Other option is POR15. Check in Indiamart or TradeIndia for a seller close by your place. Problem is this comes in big cans. You will have to convince a few more friends to share it with you.
Preparing the tank is no big deal. Drain all fuel. Pour in some NC thinner and close the fuel lid & fuel tap. Rotate the tank in all possible directions so that the thinner can reach all corners of the tank and clear any traces of petrol or oil. You may use kerosene in place of thinner to save yourselves from accidentally damaging any paint on the tank. After draining the thinner drop 2 hand full of small screws / nuts / bolts into the tank along with a mug full of water & a spoon of detergent powder. Keep rotating the tank such that the screws can scrub the inner surface and remove most of the fine rust traces. Remove all the material from the tank and give a pressure wash with plain water. Dry the tank in sun light. Then do the epoxy coating. You might need half a day for preparing the tank. Epoxy might take a day or two to dry.

Epoxy primer is available in local paint shop here, its around 900 per litre, I can coat the RX and RD with 1 litre I guess. I am first going to do the cleaning bit and then the coating, but can the coating be DIY or do we need expert hands. I assume just pour in the epoxy primer and rotate the tank in every possible direction and leave it to dry for a couple of days? I am going to take off the tank this weekend and do the epoxy coating provided it is a DIY job, else I have to find an expert to help me with it. I am also thinking of attending to a ding in the silencer and the shabby gear lever to be plated along with the silencer and the kicker. Thanks for the response, would appreciate some pics of the process and final result, May be some pics of the tank after usage of some 6-8 months would also be of great help.

Pramod, this is the kind of Clutch Setup i found when i opened my RD350 Engine.
Although no rubber rings are there with the Friction plates available in the market.
Need some insight

Like I said, ours is a wet clutch, rubber and oil are known to be not so good friends

Moving rubber parts in oil is not a great idea, I am not sure if this was a special one off creation of Delhi. Look for normal clutch plates, you can also use banshee plates, if you have someone in middle east you can get the plates.

Best of luck with your build. when you get your engine re-bored find out if they can handle micron level re-boring and honing, if will PM you the clearances you need to run and your run in would be less than 100 kms .

The picture posted by me is from eBay for a listing of Clutch set for RD250!
But I was surprised to see these in my bike during teardown , seems like OEM setup, of course the rubber rings were hard n some broken.so the introspect into the issue.
The pistons were ambika, connecting rods had AM written.
Needs some quality work
