This bike belong to my Friend and I'm working & posting on behalf of him 'History' about this bike & the owner:
He is a good friend of my mechanic and we became friends at my mechanic's garage only. He is another RX fan, never owned one but rode RX100 for a long term at his work place. He was looking to buy one and ended up buying a 1990 RX100, claimed to be "fully restored" paying a hefty amount sometimes back without taking the opinion from mechanic. Bike was glittering with custom painting and stickering.
Once we (self & mechanic) saw the bike, we weren't satisfied with both performance as well as appearance. But it's already too late. The only good thing is all papers were in form and fit to be on road. Bike was little sluggish and clearly audible noise from engine at all rpms. Months passed, the bike was used in the same condition. Couple of days back the noise started increasing and acceleration deteriorated along with evident clutch slippage. We decided not to trouble here any further.
Having a cup of tea in hand the owner asked "Why don't we restore it?" and with no surprise or hesitation we said "YES". Then we realized, my 3rd RX restoration was already put on hold for Pulsar Classic project and now if we start working on this bike, it will be further delayed. But we don't have another option as this bike is his primary (and only) mode of transportation and we don't want him to suffer. Pulsar Engine was already removed for renovation and it may reach us by next week after the mechanical and painting job. So we started striping the engine & transmission to understand the current condition. Initial Observation:
- Running on 3rd Oversize Piston
- Not sleeved yet
- Excessive scoring marks in piston as well as Cylinder
- Connecting rod free play at Crank end
- 1 Clutch spring broken
- Clutch plates lost their life long ago
- Clutch bell free play
- Worn out clutch collar
- Sprockets were nearing their end of life
- Messed up electrical harness
- Bent rear axle bolt (we had a tough time removing it)
- Excessive play in gear shift pedal What to do? Where to do? When to do?
What to do?
Since the bike doesn’t require much aesthetic upgrade, we are leaving this portion untouched as of now. Phase 1:
- Engine rebuild
- Replace all bearings
- Replace complete clutch assembly
- New screw kit
- Replace chain & sprockets, sprocket hub, rear axle assembly
- New wiring harness
- New lock set (current one has individual keys for ignition, gas tank, side lock)
- OE Handle bar
- All cables
- Gear shift pedal
- Change Transmission oil & Air Filter Phase 2:
- Better shoes
- Front Disc Brake Phase 3:
(Optional & long term)
- Painting (OE theme)
No detailed snaps were taken, but I will keep this thread updated with more snaps and details.
