Hey guys, looking for some insight on this rattle on my 2006 Honda Rebel 250.

Context on how this started: The bike was heavily overfilled on oil by accident and got really hot, which built up crazy pressure and violently blew the crankshaft snout oil seal completely out of its seat. I took everything apart to fix the leak, but ever since reassembling, I’ve had this persistent mechanical rattle.

I’ve had the flywheel off 4 times now trying to get this right. Here is exactly how it's currently put together:

>The starter sprocket and flywheel were bench-assembled (twisting past the rollers) so everything clicked in right.

>The whole assembly was slid onto the crankshaft snout together on a good woodruff key.

>The main flywheel bolt is fully torqued to spec at 33 lb·ft using a chain strap wrench to hold it.

The engine idles completely smooth and steady with the choke off, but the rattle is super clear at low idle. When I give it gas or pull the choke to speed it up, the noise seems to go away or get masked. Also worth noting: when I pulled the flywheel off one of the times, one of the starter clutch rollers completely fell out like it was loose.

Airbox is bone dry, and the oil didn't look foamy when it originally leaked out. What am I missing here? Did the extreme heat/pressure warp my starter clutch housing, drop an idler gear bushing, or is it something else entirely?

Any help is appreciated!

Hello everyone. My interceptor 650 2023 with 19k kms started showing “Check engine light” after a ride in rain.
I thought this was common as it was NOT affecting the working of my bike. Everything is working fine with zero issues.
Now out of curiosity I went to my local mechanic who has a OBD scanner tool. He plugged it in but it was showing nothing, the scanner was unable to connect to my bikes wiring harness. Then he checked the fuse and the ELECTRONIC FUEL INJECTION Fuse would stop working everytime he would connect the OBD scanner to the port on my bike.
Pulling the fuse back out and reinstalling it without the tool plugged in would fix the bike immediately. But the check engine light would stay on.

Anyone knows anything about this issue please let me know your thoughts.

My Chinese motorcycle i kid you not will not start. No lights no nothing. Had it for a while. I’ve always had to bump start it which is annoying. So I got a new battery thinking mine was dead. Still nothing. Connection is good on the battery. Read somewhere to check the fuse. Checked the fuse. Looked fine, but got a new one anyway. Replaced it. Still nothing.

What could it be? It’s irritating because i am trying to sell it.

Hello!
I have an Aprilia Tuono 125, iv only had it a couple months and I’m so in love with it!
But something is going very weird.
Sunday I went to the shops, it was parked and locked up for maybe half hour - when I come back out to it the screen was lit up and the lights were on…I panicked thinking I left the key in, I hadn’t and it was turned in the off/locked position and the key was safely in my pocket so I was a bit like wtf thinking maybe someone tried to do something to it but I couldn’t see any other signs of that (it’s really dusty from where I work and there was no finger marks or anything)
Anyway I got it home and went to lock it away and as I went to turn it off: the engine cut out perfect but the screen came back on again and it end up taking a few attempts to get it off but it appeared to stay off.
Yesterday morning turned it on fine so i thought it couldn’t have come back on otherwise the battery would have been drained surely?
Got to work - again a few attempts to turn it off, came back out a couple hours later to check on it and it was on again 😩 I rang my mate in work who has a lot of experience with bikes to ask him if he could help locate the battery cause I wanted to disconnect it so it didn’t drain it and the battery wasn’t under my seat but he was busy (this was about 11am)
Came back out to check about midday and it was off still, but when I came back out around 3pm it was still off but I see my friend I had rang earlier and he said he had seen it on again after he had spoke to me, so I turned it on and the battery was not drained so I was just confused af and then it turned off and stayed off first attempt!
Got it home and it took more attempts to get it to stay off and then later in the night i noticed the light was on through the shed door and this time it had fucked the battery I tried to turn it on and it didn’t tick over it just went into disco mode until I finally managed to disconnect the battery 😩

I have never heard of bikes turning themselves on before so I am so confused and worried, has anyone experienced anything like this at all or has any electrical knowledge to what may have caused this?

Any insight would be greatly appreciated, thank you so much 💙

heyo

i put the model last since it's sort of a model non-specific question.

last week, the baffle and packing blew out of my exhaust on the highway. i am unable to find a suitable slip-on due to the aftermarket 4-into-1 headers, ending in a 2.25" collector at an awkward angle.

replacing the entire exhaust will cost me over a grand, when the bike cost me $1200 nearly ten years ago. i'd like to keep it on the road, but i'm worried about the other issues just waiting to pop up (it's over 86k kms / ~53k miles).

i've thought about a couple of other options. either i could custom fabricate new baffles, or possibly jam one of those adjustable silencers for cars into the existing can.

would love any advice, as well as anyone willing to talk me out of parking this or selling it for parts and buying a royal enfield.

hondas aren't supposed to die

thanks in advance

As the title says, the bike isn't getting to the power band. Year 2014, so it's a Rotax 122 engine.

When we bought the bike a few weeks ago, it ran well and had lots of power and it went to the power band easily.

Now it doesn't matter how long you hold the throttle wide open, it just won't get to the power band.

Everything is stock except Scalvini performance header and Dellorto VHSB 34 carburetor.

Edit: Forgot to mention. Bottom end serviced and balanced, top end replaced a couple hundred of kms ago.

Rave power valve has been adjusted to the weakest preload in order to eliminate the power valve for diagnostic purposes.

Carb settings upon purchase were stock K57 needle, clip in the highest groove, 160 main jet, 266 needle jet.

We have:

1. Checked the reeds

2. Clean and oiled the air filter (with proper air filter oil)

3. Fixed air leaks in the carburetor boot (and verified the fix with carb cleaner while the engine is running)

4. Fixed an air leak in the exhaust header in the cylinder side

5. Serviced the power valve to make sure it is not stuck

6. Checked the compression

7. Replaced the spark plug and gapped it correctly

8. Tried multiple main jets between 150 and 170 (we are now at 170)

9. Tried K21 needle for a leaner midrange

Current jetting:

1. K57 needle, clip in the highest groove position

2. 170 main jet

3. Everything else is stock

Currently we believe this is due to jetting but we are not able to diagnose this fresher.

All advice and diagnostic procedures to identify the reason and fix it are appreciated.

1985 ZN700 fires right up when cold, like instant, but if I turn it off after riding for 5 to 10 minutes it will act like the battery's dead all lights on cluster go out and it chugs then wont turn over...but if I let it sit for 3 to 4 minutes after I turn it off it then it fires right up....ive replaced the starter clutch, battery, starter solenoid and next is my ground wire. At a loss for what it could be? My dash voltmeter will read 10v or less when its doing this but if i return 3 to 4 minutes later the dash will say 12 to 13.....not sure how that's possible. 1985 Kawasaki ZN700

I bought a 2014 Yamaha Wr125x as my first bike thinking it would be a easier fix. Seller said it was a faulty starter motor turns out it isn’t, I’ve checked the batter and it’s fine, I pulled out the starter and it works fine. It starts easily if you bump start it. I’m suspecting it’s the starter clutch, but I’m not sure and i don’t know how to check it. Any help?

so like i said for yamaha jog 2006 49cc if someone can help me i will be very thankful
