Playing around tonight, and switched out my hallman MBC for my GrimmSpeed MBC. The hallman must have a light spring in it, because it will only crank to 19psi. It's set at 20 right now, and it's a lot of fun. When my converter locks at 90 it goes into warp speed lol. It sets back hard into the seat.
Last time I went out playing with others, I could only get a ninja 1000 to run me. I was on 15psi and he got me by maybe 2 lengths. I wish I could find the same guy and run him to tonight. It feels like a freaking beast! Too bad tonight is New Year's Eve. Next time out I will be hurting feelings.
Happy New Years to everyone!!

 

Lets get a vid of that beast!! Happy and safe NYE
