Raptor sputters while doing wheelies
I was out learning how to wheelie my Raptor today and ran into a problem. First off lots of good info on learning to do wheelies I started with one knee on the seat gassed it up in first from a crawl here's where the problem is. When I get up to the balance point on doing about 5 to 10mph the motor sputters and coughs so bad I can not maintain the slow speed wheelie unless I open it up. The bike is up and balanced and all I need to do is feather the throttle (1/8th to 1/3rd throttle) but it coughs so bad it is difficult to maintain???
Please help me out, is it because the slow speed curcuits in the carb are out of gas ie being tipped up too much or is it because the bottom end is too rich / air screws out too far.
If I do higher speed wheelies with say 1/2 to full throttle no sputters at all.
I am at 3000ft full yosh, cut up air box, 150/155 jetting, air screws at 2.5 and 3 no other mods.
