ahell

Today, Piston, rings, cylinder, clutch, selector, clutch arm, carburetor gaskets, spark plug, intake pipe, valve box, cylinder head, air box rubber, rear frame: new original! Used air box in good condition. I ordered clutch and throttle cables. It feels good to be moving forward, but I still have work to do. It took me quite a while to gather the parts for this machine. When I compare it to the TYZ, there is a world between the two. The Yamaha was much more modern in design and manufacturing. This 311 was really the “before” Honda engine.

ITALKIT CONROD.

I'm waiting a new conrod to finish the engine. All new bearings, seals, original piston Gilardoni, original new cylinder, new rings, new clutch ... all new engine ! 🥰

38 pilot jet right. 3.5 turn fuel screw (original 35) The replacement air filter foam is “lighter” than the original Montesa. The engine therefore breathes much more air.

Mitani alloy clutch +250grs

All new brearings and seals.

New CSP engine plate. Engine run like new one but need bigger pilot jet to be perfect.

Next order: Engine bearings Dellorto gasket kit

I made a pair of intake & exhaust caps. (I don't regret buying a lathe) Washing in an auto center. I insisted on the painting which was going away. (I'm going to repaint all that) Back home, drying. Disassembly with no other surprise than 2 cylinder studs in love with their nuts. The cranckshaft is beautiful. No rust from what I saw. The connecting rod looks good. The ignition housing is well ventilated. No rust at all. Just dust.

Cleaning, upper and lower engine alignment, replacement of crankshaft bearings, gearbox output bearing, selection barrel and spy gasket. All new crankshaft and titanium screws.

I found a new cylinder - piston assembly. (but without the rings) Although I haven't opened the engine yet, I jumped at this chance. These original parts are difficult to find. I found the upper ring at one dealer and the lower ring at another. It gives you an idea of the puzzle of restoring these motorcycle. I will sell my complete (old but good) top engine. It will make someone happy.

To carry out my other projects, I bought a 3rd 315R. A 2002 model. The objective of this one is not to make a replica that stays warm in a collection. But a completely overhauled motorcycle, precise and efficient as the original for regular riding. The original fork (in very good condition) went on the Ogawa RTLF Replica. The fork (black tubes) of the 4rt (now RTLF) takes place after a major overhaul on this 315R The shock absorber is completely overhauled (gaskets, buffer, drain, pressure, ball joints) New linkage, new rockers. Carbon swingarm protection, and carbon kevlar fork guard. Swingarm pad, crown guard, front number plate, gas barrel, original grips. The covering receives a two-component varnish resistant to hydrocarbons. The engine will be opened and overhauled. Overhaul of brake calipers (ultrasound, special grease, etc.) Ultrasonic carburetor overhaul and new parts (gaskets, bushel, needle, idle jet) Some stickers taking the look of Lampkin's 2002 motorcycle... and frankly, I find it super pretty. Engine overhaul report: - piston from Vertex - connecting rod from Italkit - main bearings and seals - water pump seals - Sprocket seal - various joints necessary for reassembly I hope you enjoy. Alain from France.

I have found 2x OEM crankshaft and conrod. So, I remove the Italkit for an other 315R. The flywheel was machined from 3.5kg to 3kg. The engine is running well. No vibration, no leeks. Great and Happy !

New shift drum Light weight flywheel and overhaul showa shock with race spec.
