Yamaha sr500 - Engine restoration, part 1 

A thing of beauty how pieces of metal joined together can produce a machine that transports one from place to place

Fantastic! Muchas gracias!

Using an adjustable spanner is a very good way of damaging the cam chain tensioner nut.

Nice work, dude!

Nice workshop :)!!

Keep these coming

Nice work, my xt engine will be getting similar

So you only have the motor not a bike ? I have a 1978 SR500 I've fitted a simpler 36mm Mikuni carburettor I got off eBay from the US it went straight on and runs great with only some adaption to the throttle cable and the tubing to the air cleaner and a different "non vacuum" fuel tap, you can use the original fuel tap if you use a later type of manifold that has a vacuum tube or drill through the front end of the carburettor and install your own vacuum tube As for identifying its year it might be hard to do without its numbers The magnetos have had a lot of changes over time maybe that could help identify it's year If you had the whole bike the 78s and 79s had mag wheels for "tubed" tyres and front and rear disc brakes I'm pretty sure they went to "tubeless" tyres on the 1980 models with mag wheels with a front disc brake and a rear drum brakes

Hello. Could you please tell me what that plug by the gear selector is for? mine is leaking some oil at that plug. thanks

With the engine running, the indicator for cam chain does not move in/out the slightest bit like I've seen it should. although flush with the big locknut and bike runs ok so far but still bit of a rattly sound from engine. Any ideas?

Kommer du ihåg vad det kostade att renovera motorn? Packningar, packboxar och lager m.m. ?

Bra jobbat! Vart i Sverige bor du?

can you give any good websites for parts? i know a few such as cmsnl etc but maybe there are some i am unaware of

it is the 2j4 engine

Looks like a 2j4 from 1979.

Yo don't have a new engine or
