Low end stumble

[jrdrag5475]

Hey guys

I have a 2005 TRX 450r completely stock and it now has a low end stumble to it meaning when i from a stop go full throttle it bogs for 2 secs and then takes off. I was thinking to clean out the carb and try that? but does anyone else have anything i should try to fix this. My air filter is clean! im not sure whats causing this but any help would be appreciated

Thanks

U more than likely need to change your leak jet to be richer in your accelerator pump.

The 05 450r doesn't have a leak jet or any good way to adjust the pump. Install a larger pilot jet the bike will start better and have less bog of the bottom.

Ok sounds good.

Also i forgot to add the only way it would run better is if i turned the choke on? should i still intall a larger pilot jet?

Thanks again

Yes you need a larger pilot
