hello. i(beingthe smart *** i am) decided yesterday to remove the butterfly assembly out of my htev valve on my 929. big mistake! it sucks on the low end power now. till you get to about 5k rpms there is no power. so i had to order another htev valve. for any of you guys that are thinking full exhaust would be better, think again. if i had it all to do over i could have saved myself some money. no matter how i set my power commander it still doesnt matter. what do you have to do to run a full exhaust?

 

take the bike in and have a custom map done it will help with the issue. I love my full arata system but you will lose a little in the bottom I can handle that for 137 to the ground and smooth power

 

where would i take it to? i have a erion bolt on, k&n filter. i tried the map for erion full and aftermarket filter and it didnt help. also it cuts out between 4k and 7k rpms until it warms up to at least 150f. is there something im missin here?

 

If you want to leave it deleted then just look around at the stunter sites. Thats a common mod to help adj the idle. I run my idle at 2500 when lot stunting, but if I try to turn it higher it just goes to 5k after I touch the throttle....wish they would have never used that setup on these bikes.

 

Take it to a shop that has a dyno and the right equipment andsee what they can do. It should be a custom map not just a map you could download.
