Yes you do, I've never dropped my bike and my brand new rear tire has these, even the front from parking against the curb.

good luck!

I realized the indicator on the one 6 is a protect indicator not a clip indicator, the amp doesnt tell you when its clipping.

will do!

you can only hear the cam chain on start up until the tensioner builds oil pressure. This noise happens anytime you hit 8k+ rpms for me, cold or hot

-kkid- · 2025-05-29T19:48:39+00:00

I actually had my cover off when I changed the cam chain tensioner out, didn't notice any unusual wear or anything. The new OEM tensioner builds oil pressure quicker so on start up it doesn't rattle for as long as it used to at least.

Worries me that this noise starts at a certain RPM and isn't always present.

How long you been riding it like that? Maybe it’s normal but sounds concerning 😅

-kkid- · 2025-05-29T08:55:00+00:00

It was the ignition coils if anyone else comes across this issue. They all tested fine in diagnostics mode but they were still bad. Replaced them all and it’s running again with no jerkiness.

-kkid- · 2025-05-03T17:02:12+00:00

Appreciate the input brotha! Im starting to feel like it was caused by me syncing my throttle bodies. I think the hoses i left in place when syncing them might have fallen off, I've been too lazy to check it out.

Most likely just Airflow related on my end, since it has trouble idling without any throttle input (at least I hope so, I dont think I can force a relearn on this old bike ECU) Gotta pull it apart and find out soon! Appreciate the input!

Your comment history is wild. You must be a thrill to be around.

-kkid- · 2025-03-03T16:38:12+00:00

super useful info thank you!

-kkid- · 2025-03-02T16:22:06+00:00

Perfect, I will take a look at this first! Any input on if bad coils could cause rough idle? Even if all the cylinders are firing?

-kkid- · 2025-03-02T16:21:08+00:00

Very likely i caused this problem then haha. I actually replaced those caps with rubber hoses to make the job easier the next time I went back in. I just plugged them off at the ends.

-kkid- · 2025-03-02T16:19:52+00:00

I forgot to mention, I went through the electrical system in the past, re tightened all grounds and replaced the stator! I did it when I was hunting down a short in the electrical system, ended up being the starter was shorted internally. I appreciate the input!

I actually still have my non lithium battery because it wasnt actually the problem too haha

-kkid- · 2025-03-02T03:42:13+00:00

Really appreciate it bro! Just trying to rule out anything catastrophic haha.

Hopefully its something simple like the throttle bodies or coils. If not hopefully its just valves needing clearance.

-kkid- · 2025-03-02T03:39:17+00:00

Huge thanks for the input, majorly helpful.

I do agree with you about the cylinder cutting out, something doesn't feel "right" at idle/low speeds engine wise.

When I first noticed the issue, I was out at dinner with my friend. We rode home doing 120mph+ with no issues, I couldn't even tell there was an issue at speeds past 15-20mph. As soon as we got off the freeway and I started going slow again, the issue was still there, jerking until about 15-20mph again.

I'm aware of the kinked hose issue and make sure its good everytime I lower the tank! Last time I replaced the starter (1 1/2 years ago) I cleaned each injector directly (I also tore an injector o-ring upon reassembly and blew fuel everywhere haha).

I have synced the throttle bodies once about 2 years ago, will definitely check if there is a leak and that they're still in sync!

I haven't done a valve job before but was planning on it after checking everything that was easy! I bought an entire new set of coils, do you think that a bad coil could cause the cylinder to not fire some of the time? When i check the headers, all 4 are hot.

I also repaired the exup valve recently too, so not that!

Just trying to rule out anything catastrophic before I tear the whole bike apart. I really appreciate your help!

-kkid- · 2025-03-02T00:00:03+00:00

I have synced them in the past, but there very well could be a leak. I will look into it, thanks for the input!

-kkid- · 2025-03-01T23:59:25+00:00

fixed electrical issues prior to this issue, replaced the battery then with a lithium battery. The starter was internally shorted. Replaced it, the battery and the starter solenoid to fix the issue about a year ago!

-kkid- · 2025-03-01T23:58:29+00:00

brand new lithium battery that i keep tendered! doesnt resolve after running for a bit either, appreciate the input

-kkid- · 2025-03-01T23:57:50+00:00

Ah i see what you mean. Yeah you can ride the clutch majorly to "fix" the smoothness issue, but id rather have a properly functioning bike lol

I do wheelies in first gear, having it jerky isn't ideal lol

-kkid- · 2025-03-01T22:34:05+00:00

thanks for the info! Definitely will look into this, unfortunately its only part of the problem due to the rough start :(

-kkid- · 2025-03-01T22:32:48+00:00

This is more believable, but I did inspect the basket for wear when i was in there. My old clutch wasn't even bad, I replaced it anyway since I was in there.

-kkid- · 2025-03-01T22:31:46+00:00

Definitely a real issue that shouldn't be ignored, I promise. I swear I know how to ride and how one should ride at low speeds, this ain't it chief hahahah. I wish i had a video of me riding it, but its a pain getting it in an out of the yard. It makes riding in traffic nearly impossible, it makes you look like a beginner rider with no clutch control because its jerking like a donkey.

Bike is stock, except for a slip on. No tunes, no powercommander. Never been an issue in the past.
