My nephew has a 2007 Suzuki ltz 90 That's not running right.
First of all it it sat for 4 years. I got it out of storage did a oil change and put in new gas and it started right up but it idles really high and it bogs and dies as soon as you touch the gas. So far all I've done is clean the carb the jets were clogged but even with it cleaned It didn't make a difference.

It ran fine before it went into storage.
Any ideas on what my problem may be

Thanks.
