x2 questions help needed

[doughboy]

greetings all...

I have had a new x2 for about 2 months now. have two questions hoping for response.

#1. have lost top speed over past two months, orginally 38-40 mph, now topping out a 31-32. broke bike in according to instructions. any thoughts or similar situations?

#2. bike always stalls at intersections unless i give it gas. is this common or can I fix the problem?

any response to this thread would be greatly appreciated

Thanks
DB

Do you feel the same resistance when you pull the pull starter? or does it seem easier to pull?

How old is your mix? You should only mix enough for the day, but definantly no more than 3 days worth.

Same spark plug?

Have you changed anything? or is it all stock?
