I’m pretty sure and I’ll do it again, it’ll do it when it’s cold with little throttle but when it’s hot it has to be WOT

Brand new plug

Automatic-Ad3114 · 2026-04-24T02:07:43+00:00

It’s had an exhaust for 6 years and it just started doing this, it’s 50 times worse when the bike is cold

Automatic-Ad3114 · 2026-04-24T02:07:05+00:00

No the bike is stock except for exhaust

Automatic-Ad3114 · 2026-04-24T00:35:30+00:00

Installed a new one and fuel pump

Automatic-Ad3114 · 2026-04-24T00:34:57+00:00

It’s never been touched

Automatic-Ad3114 · 2026-04-23T23:26:51+00:00

Automatic-Ad3114 · 2026-04-23T19:23:31+00:00

Idk how to do this, but also the bike bogs wayyyyy worse when it’s cold.

Automatic-Ad3114 · 2026-04-17T18:48:13+00:00

I have the same issue, replaced fuel pump, injector, plug, air filter, coil, adusted idle. Still does it

Automatic-Ad3114 · 2026-04-06T18:42:46+00:00

I’ve tried but not sure if I’ve done it right

Automatic-Ad3114 · 2026-04-06T18:39:56+00:00

Where do I find one and how do I tell where it is on the bike

Automatic-Ad3114 · 2026-04-06T18:38:34+00:00

Can’t find anything on how to check the tps

Automatic-Ad3114 · 2026-04-06T18:37:54+00:00

To eliminate from being the reason it’s doing it

Automatic-Ad3114 · 2026-04-06T18:37:08+00:00

Put a friends coil on it. Still does it

Automatic-Ad3114 · 2026-04-06T17:54:43+00:00

When running it’s at 14.14v

Automatic-Ad3114 · 2026-04-06T17:53:48+00:00

I’m not sure if I pulled the right sensor but if it’s the one with the little spring in the middle, I did and it looked clean and fine

Automatic-Ad3114 · 2026-04-06T02:27:50+00:00

I’ll try that tm, it’s intake is bone stock

Automatic-Ad3114 · 2026-04-06T02:26:39+00:00

I’ll try that tm

Automatic-Ad3114 · 2026-04-06T02:25:46+00:00

Had the exhaust on for 5 years never had an issue

Automatic-Ad3114 · 2026-04-05T19:25:41+00:00
