I can give a good deal on my Sparks. I have the Barker duals, dont need both.

 

boyz i got both of my hmfs installed, i didnt tell much difference in the ds650 except more low end. the yfz cam alive it is plum bad now! we ran open air box k&n and jetted carb with hmf slipon it now pulls my ds650 by about 4 quad lengths. where when they were both stock the ds650 pulled by about 3 lengths! the hmf is awsome on both a lil loud but nice pipe, i have now purchased one for the raptor!

 

They're awesome. Mines a whole different animal. Get a full system and jet it fat on top.............you'll like. [img]i/expressions/face-icon-small-happy.gif[/img]

 

The CT woke the bike up big time. After I got it tuned it was like a different bike. Awesome!!

But, after about 2 hours of pure fun, she threw the rod thru the case going up comp hill at the Cinders. Not Pretty!

ALWAYS CHANGE THE ROD WHEN GOING TO 686 HIGH COMPRESSION! I didn't listen.

Now I have to spend some bucks. It will be a 727 this time.
