2.) Converting a Rx100 to 5 speed ..or 135 to 5 speed.
3.) Whats an oversize or porting is beyond me all i need to know is how will it justify the work. (i.e will it increase speed/performance).
4.) Getting all stock parts from the market or repairing the old ones. (Including the engine barrels or pistons).
5.) Even if the engine is in running condition, buying the barrels, pistons and working on them is better or modifying the old ones is better.
6.) Performance enhancements which suit the bikes image too. (imho the proton silencers on yamaha look yuck to me).
7.) To convert it to a CDI for hassle free startups.
8.) Have read a lot of negative comments for Rxg, basically why not the RXG?
I am basically a nostalgic owner of a 1979 Royal Enfield Bullet and have changed the theme on the bike 3 times in last 10 years since the day i acquired it from my dad. So Rx is the only other bike that fascinates my imagination as building a bike from scratch or getting a bike in mint condition is my passion.
The search for one is on but your valuable advices will help me bring a better baby in my garage. |
That is a decent budget you have for a quality rebuild. Here are some answers to your questions:-
1.) Buying a Rx 100/ 135/ Rxg /Rxz (4sp or 5sp).
You first need to decide which one you want. Everybody has his own preferences.
2.) Converting a Rx100 to 5 speed ..or 135 to 5 speed.
Its a waste of time and money. Just buy the right model you want. Too much of work required on the engine to convert it to a 100.
3.) Whats an oversize or porting is beyond me all i need to know is how will it justify the work. (i.e will it increase speed/performance).
Oversize is the next size of a piston of what the bike is currently running. Forget about porting. Dont even fall for mechanics or people boasting their special skills and results.
4.) Getting all stock parts from the market or repairing the old ones. (Including the engine barrels or pistons).
Market is full of fake parts. you need to know the right source for them.
5.) Even if the engine is in running condition, buying the barrels, pistons and working on them is better or modifying the old ones is better.
Again, running a stock engine is the best bet for you. Dont modify any part.
6.) Performance enhancements which suit the bikes image too. (imho the proton silencers on yamaha look yuck to me).
Which performance parts are you looking for? A stock RX can still be made faster and peppier by adding a bigger carb, UNI filter, fiber reeds, expansion chamber etc.
7.) To convert it to a CDI for hassle free startups.
It already has a static CDI. You can have a digital CDI as you save on other not so recommended mods.
8.) Have read a lot of negative comments for Rxg, basically why not the RXG?
The RXG had some problems in their port set up which used to give some jerks while decelerating but later it was solved. I am myself having a 1997 RXG and am quite happy with it.
Start with deciding on which model, body styling you need. Search for a good mechanic prolly who has done some rebuilds for your friends. Get someone who knows about the bike and can identify you parts. Stay away from guys telling you big stories about their rebuilds and how fast they are etc. and who dont have their own workshop.
A good rebuild involves sandblasting the chassis, block etc. , good quality stove enamel [bhatti paint] , High quality chrome plating, zinc plating, Crank rebuild, Block boring, attention to detail and collecting all the necessary parts beforehand. Where in Mumbai are you located?
