I contacted Sparks racing about some conn. rod bearings for my 400ex. I was told by Scott; "I have plenty in stock" so I sent the $53.00 money order. Two weeks passed and I called him up. "Curtis wants to use these bearings for other quads". "I can send you the rod pin and a partial refund" So, 2 weeks more pass and no rod pin or refund. I call Scott back; "We mailed your money order back" It was postemarked 1 month after he initially recieved it! The partial refund couldnt have been sent and lost as he didnt know I didnt get it. You guys pay out the *** for this service??? Check out the $239 Connecting rod he sells--You can buy that exact rod direct from Carrillo for $175!!
