Hi , have you done any other work on the bike, has this just happened, Chain and Sprocket change? and does it happen at certain rpm's or just 4th gear

 

i just bought the bike the sprocket where about shot so i did replace both sprockets

 

oh i also replaced the chain the orings where bad in the other

 

Were the sprockets factory size, that is as per manual,

 

Yes everything I done I replace with stock just put new

 

What happens at 60 in 3rd gear? At what rpm are you trying to pull 4th gear?

 

Well I’m not sure about rpm I know if I try to just cruise at 55 60 it does it or wether I open it up it does it. I’ve read a forum on dai an looking into that at the moment. I replaced my fairing an when I did I could remember how the bracket when to hold the tubes in place so I just set them in the spot they went. Maybe they aren’t getting the full air flow. I also repainted my tank an looking into my vacuum on my tank

 

The DAI solenoid kicks in at about 20mph, (if working correctly) make sure you have the Air solenoid Electrically connected, This is how the pipes should be connected

 

I’m going to try as see today what I can come up with I will post what I find. Any other idea to check let me know I’ll keep trying till I find it
