Have you removed the charcoal canister?

Throttle bodies could need cleaning, my old bike would die because it got some oil/dirt in the idle circuit passages.

Yeah, charcoal canister was removed. I did a deep cleaning on the bike in the winter where I pulled the air box off and clean the throttle bodies. That's when I added the rapid bike, qs, and cut the hole for the MWR filter. I took the for a ride today, I was very surprised at how fast the top end was. I think its going to do great at the track in few weeks.

Can you share parts/ pics of how you did your quick shifter?

mikejuice · May 6, 2019

Yeah, I have the rapid bike quickshifter with the Geckoracing.it rearsets running GP/reverse shift. I believe the sensor works both ways, however you will need to run rearsets of you want GP/reverse shifting. Install was pretty straightforward and comes with a necessary shift rod lengths. https://imageshack.us/i/poHLOnbGj - pic for reference. https://geckoracing.it/it/index.php...t_id=222&virtuemart_category_id=3&Itemid=9999
