[@2wheelLove]

That's a hydraulic chain tensioner. Almost no tension is put on the chain until the oil pump creates pressure. And yeah, that's an air temp sensor. Another reason for the poor running could be the pcv could of lost its tps settings since the battery went flat.

[@1one3_Racing]

Yeah, the whole time he's changing it I'm thinking "I hope that's not a hydraulic tensioner and he's wasting his time"

[@deadslow201]

Also fuel was old, and it takes a while before new fuel runs through pump and lines and nozzles; does not start, idles poorly. And battery was empty, engine cranks but spark is very weak; does not start, idles poorly. So next time, take light fuse off, start the engine, and run it (using throttle) at least 10-15 minutes before doing anything else. Also air intake/ air filter was totally changed, that leads easily to start and idle problems.

[@Mad-Duk_Machine_Werkes]

Thats not an O2 sensor (those go in the exhaust header) thats prob an intake air temp sensor!!! No such thing as "Tuned for Warmer weather" it either has a fuel issue,(clogged filter? injector?) or has still the stock Map in the ECU and was never flashed or doesnt have a Power commander or whatever after the guy did all the mods- with modern Fuel injected bikes you have to alter the Computer chip in some way to compensate for engine mods, airbox mods, etc - (Like jetting does in a standard carb bike) PS: a Suzuki DR650 engine would be a better choice, IMHO

[@JM-mn4ph]

It's the battery. Fuel injection needs a well charged battery to run properly. And as stated in other comments that sensor was an air temp sensor that changes your a/f mixture for cold starts.

[@rprokopow]

Its valves, timing, or compression. Yes fuel injection needs power to run but once its running it can run normally off the charging system so the fact the its running and still running like crap says its not that. Last owner threw all kinds of junk on it and probably messed up a mixture of stuff in the top end

[@rprokopow]

Also air temp is gonna be the same whether its dangling on the side of the bike or in the intake. As long as its not near the hot exhaust or cylinder hes good.

A better way to tell if a timing chain is worn out is to turn it on its side (as in the pins of the chain are up and down pointing at the floor and ceiling) and hold the chain on one end...a new chain will be pretty straight and a worn chain will sag really bad. I think your issue here was fuel related like others mentioned. The lines and everything still had crap gas in it and would take a bit to get fully flushed by clean gas. You got her running though! Persistence always pays off.

Try a valve adjustment, the smokey exhaust is a give away for me.

I second this, hard starting, poor idle, smoke. Get the valves adjusted to spec.

Just a heads up, the issue was the sheered pin. I’ve had that once before. The sheered pin allows for that timing to change and float wherever it wants to be. It could run ok and then like dog poo. You finding that and thinking you did it is not at all the case. It was sheered before. You replaced it and had the correct timing, which corrected the issue

[@DirtGearTv]

650 swap would be insane. As far as this engine goes, it’s behaving like it has low compression, slap that compression tester on it and see where she’s at. This could be caused by a valve not fully closing.

Hey, I think you have to prime the timing chain tensionner with oil to make it work properly. And it would probably help to check you valves gap too! Have a nice day!

[@PiazzaWoodWorks]

It’s an air temperature sensor, not a maf or o2 sensor, sounds very rich, The chain wasn’t stretched, the tensioner gets tight with oil pressure,

[@rprokopow]

Id be interested in buying the motor and wiring if your selling! Would love to put that on my ct70

[@seansysig]

The carb had bad gas so a cleaning is a must. The timing surely was out as it sheared the key! The hard starting is due to higher compression you need a decompression valve to fire up easier.

[@NOONE-hp8bw]

Groms are fuel injected and that key that got sheared was for the magneto flywheel not the timing

[@SwagatVlogs]

Bro you messed up the ecu mapping when you shoved that sensor inside the air filter. The last owner must have mapped it to stay in open air. Simle fix !

[@chrisatc627]

It's a Intake air temp sensor doesn't matter if it's in the filter or outside, air is still the same temp, would never mess up the mapping, your thinking of a mass air sensor

[@PHUSII]

I had an Yamaha TT 2005 4 stroke engine with big bore kit and bigger lift cam and it was the same, cold you could hardly get it started and them when it was warm, it worked like no other. So maybe the cam makes it harder to start when cold. And is there a choke on the carb? Mine had and helped with the cold start.

[@MAJ_T_Bagger]

I'd say pull the air flow sensor out and see if it runs better, also does it have a cold start sensor and are the wires backwards if it does? Had a similar starting issue on an engine swap I did a few years back in an old mazda, hard to start then idle would jump up to 1500rpm once warm.

[@Goggleyedtrufflepig]

Was the teeth on the timing sprockets ok they looked worn which would explain the chain feeling slack and why the tensioner wasn’t doing much. Defo check the shims for the valve timing, cheap fix.

[@netxphotography]

If you should need a set of tires, I have a set of Avon tires that I can sell very reasonably. I didn't get them put on my Grom before I totalled it.

She's running fine, just leave her running with throttle on for 10-15 minutes to clear the lines. Make sure to have a properly charged battery also. Yes, the larger piston will be harder to push with the existing starter motor.

looking at the rollers they where worn down and had to much slack this would alter the timing i would also check valve clearances also it is fuel injection unless it has a self correction feature with that filter it will be getting the wrong fuel air mix

[@MaNNeRz91]

Injector could need a good clean as well as the sensor that is for reading intake temperature or intake temperature AND flow. The air going in could be warmer than the sensor is reading. This makes the map run richer because it thinks it's colder or it could also control the cold start idle control.. just a few things to check over. Had similar issue with a Kawasaki w650 before. One cylinder was running ok the other was running so rich it was flooding and running like shit. The intake temperature wire had snapped off one of the air boxes and it ran beautifully when it was connected back up.

In a kit or hole motor that still derect fit in the bike that about all you can do the next step is the cbr250r or cbf is a better fit from what I've been told.

Timing chain stretched from previous owners doing wheelies and clutch dumps which everyone seems to do with these groms and that is also exactly why they added an oil cooler was to be able to ride long wheelies and still get oil to the piston so you sir have bought a beaten up ex-stunt bike which it is still a Honda so no fear just replace and repair anything that wears over time and then you should be good but id also try and put as much of it back to stock as I could...
