Sure, here is his website. http://www.litzracing.com/, his name is Steve, if you contact him for services tell him "DuHamel" sent you , cuz he has always called me that since way back when. LOL
He has been doing suspension work for well over 20 years. He does Rickey Gadson's dragbikes and many top dirtbike riders' suspension as well as many supermoto and roadrace bikes. And his prices are very reasonable.

we also rebuild shocks and can recharge them if you do it your self for 8.00... rebuild total cost is 1.25 hours labor $75 plus 1/2 container of fluid about 8.00. charging is included

if you want aftermarket valveing add 170 plus the cost of spring 110. you could supply your own but we use gp suspension for all custom applications. we have found that elka shocks work just as well as the higher dollar stuff at a more attainable price plus when we order one it is already pre set to your weight and ability.
