Mini Maddness

I just got smoked tonight by a backyard exhaust ported 40.2mm engine. The driver has an ada reed, timing key, clutch springs, and has bored his carb to 14.5mm. He also weighs 40lbs. more than I do. I can't look at him top-end. I have a 17:1 ADA big bore boosted compression kit, ADA reed cage, Walbro carb kit, Boost bottle, timing key, and clutch springs. His bike revs like crazy and does not miss a beat on top-end (absolutely no sputter). How can I get the revs up in my engine? The only stock item left on my bike is the exhaust, however, I am running a straight tip which seems to have improved it a little. I should not be losing to this bike. If I need a performance pipe, which pipe will increase my revs the most? Any other ideas? Hard to justify everything I have done to my bike when that bike comes from behind and makes me look like I am going backwards.
