I purchased a Hemsuim HS250ST-6 ATV 250cc from Family go karts. I lasted 2 rides for my Son, It started Smoking. I contacted Jeff Becker the owner. Filled out the forms and sent Pictures of the enging problem in February 2009. I have sent more emails then any one could amagin. Attorney letter / Filed with the BBB in Minn. Nothing has even been done. I founfd out that Warranty Protect / Gloria McDonald would take care of the repairs. I contacted Her, Two month's go by, She finally talked with me. After taking it 38 miles my self to a shop She set up. It stayed their 54 days, They could not even get the head off the engine. I picked it up and brought it home. It has been in my way / In the garage ever sense. Jeff Becker is a LIER. He will not Help any one. Their sale's technech is Fraud. I will at some point in my near future take this CRAP to Minn.and confront Him Personally, If I have to I will cut the darn junk up and leave it at His front door. Family Go Karts is a Dam Joke. I assure everone. DO NOT BUY THIS CHINESE JUNK.
