Frank. I like the swing arm. It was worth the price. I am using a pingel strut set low. I am not sure if that,s the way to go. I would have chewed up My tail section using the shock. After I raced the turbo, I adjusted My front. Stiffened compression and looseded rebound. The wieght transfur between shifts was causing Me to loose traction. On one run that I have on video the bike did about 10 wheelies and a 9.40 at 157. even a 4th gear wheele when it caught. Very wierd. My tire had spun on the rim and the Mickey had 130 grams to balance it. My quickest run was 9.345@ 1.678 60 ft 330 4.228 1/8 6.219 1000 ft 7.915 157.01. My best 1/8 mph 127.33 best 60 ft 1.630. My mph was consistant 157 - 158.45 second gear spun bad on every run but I was never able to shift in time. Got any tips. I have only been a part time racer for the past 2 years.
