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

[@PONSR500]

Fantastic! Muchas gracias!

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

[@bjornedwardh3385]

Nice work, dude!

[@tomaszpawlik6082]

Nice workshop :)!!

[@MrSnoozee]

Thanks!! :)

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

[@johndocbikerestorations831]

Nice work, my xt engine will be getting similar

[@pmacc3557]

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?

[@pmacc3557]

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

[@philipdanielsson5492]

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

[@ryankane4261]

Keep these coming

[@MrSnoozee]

Thanks, that's the plan 👍 Since I dont have that much time for for this, there will be some time between the uploads but be patient part two is coming 😉

@@MrSnoozee I just picked up a 78 sr500 barn find. Year on license plate is 83. So I'm not sure how much TLC it is gonna need, but I cannot wait to get going on it

[@MrSnoozee]

@@ryankane4261 Thats awsome! Good luck, are you posting the progress somewhere?

[@ryankane4261]

@@MrSnoozee no I don't think so. I have no video equipment, patience, and I'm not very computer savvy lol

@@ryankane4261 Yeah sometimes it's nice to just focus on the build.

Looks like a 2j4 from 1979.

[@hodaka1000]

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

[@MrSnoozee]

I have a frame and a gas tank wich were included when I bought the engine. The gas tank isnt from a sr500 but the frame should be from the same bike as the engine. Maybe i can get the year from the frame numbers 🤔 I'll probebly do the same as you and fit a aftermarket carburettor. 👍

@@MrSnoozee Don't know if you're still looking for a carb? If you want to keep it all original I might be able to help you out. I have a few laying around as well as loads of other original parts. Grt Marald

@@maraldtimmer4605 Hi, thanks for writing! The project is on pause right now (looking for a workshop press and work has been taking alot of my time) but im still looking for a carb! Lets keep in touch and when i start again ill contact you? // Kristoffer

@@MrSnoozee it's the same everywhere. But that's okay. When time comes, let me know. Grt

[@pointingdog7235]

Both of my SR500's had a number on the engine and the frame on the steering head. Mine were both 1978s and as it seems to me is that the engine is on the noisy side just how they are. I think that a synthetic oil would help quiet the engine down. Maybe something like the Mobil 1 motorcycle oil for a Harley Davidson. The best of luck with your rebuild.

it is the 2j4 engine
