Just got done putting a 136 Expert X with a BLT kit in my 01 780 SRX. I installed a Maxium Performance 136 tunnel extesion with the stock SRX rear heat exchanger and protecters. I used a 136x15x1 Hacksaw with 1.175 woody"s gold digger studs. I changed out the Works shocks that come with the BLT kits with some SRX long travel Ohlin's. The Ohlin's were custom made for the snocross team. Added some C&A pro ski's. Changed gears and I am ready for snow to do some clutching. I hope this rides just as good as my 04 Warrior that inspired me to build this.. In which I had put a bender exhaust with a ECP kit on it. Ohlin's up front and an Ohlin M10. Changed out the 1.25 ripsaw with a 1.5 ripsaw. I also put C&A pro's on it. Rear heat exchanger, belly protector and a 2 inch riser. It was the most awsome trail cruiser I have rode to date. I hope my old 2 stroke out performs it. I will post some pic's of the 780 SRX and Warrior soon. Bring on the snow.
