My bike does some backfiring and runs very crap on full throttle. Seems as though it loses power on the top end. any suggestions? I just bought the thing. Perhaps it just needs an oil change and a new spark?

the plug needs to be changed.. go with the ngk cr8eix ... it costs but well worth the money... around 7.00 or 8.00

I forgot to mention that its not brand new, it has a trinity stage 4 full exhaust, trinity efi and air filter with the lid off.

I will change the oil and spark and get back to you all
