Ulmer mapping on pcv and air box mod on 2011 apex xtx

[icebreaker]

Installed pcv from Ulmer today with air box mod, put on 80 mile trying it out all I can say is very nice!!!!!!!!!!! runs awesome, great throttle response super crisp at any rpm. Lots of mid range grunt and very noticeable top end power. Picked up 500 rpms. Highly recommended.

Did you do any clutching or was the stock clutching fine

I stayed with the stock clutching because my rpms were a little low and with the extra power now its right on the money. Don't know if any clutching is necessary on these from what I have been reading. The only issue I have with clutching is when your in the twistys it doesn't back shift as good as I would like. Some times the belt sqeels. Does yours do that??
