Just Mike Posted March 23, 2012 Posted March 23, 2012 I think my kids 400ex is about to go down. I am thinking of doing the 440 kit if it makes much of a difference. Just wanted some input as what to do with it like what kit, New crank, Jetting and any other helpful info. Thanks. Quote
Jakster884 Posted March 23, 2012 Posted March 23, 2012 Mike I had a 400ex and did the 440 Athena kit. It made a hell of a difference. Go for it. That thing will pop wheelies all day long. Good luck. Quote

Good luck. Cool. Thanks. Talk to TJ over at Pure Evil racing. I want to build it myself and I hate bugging shop guys when I don't intend on using there services. Quote
sanddunesaddict Posted March 23, 2012 Posted March 23, 2012 I always heard the 440's ran hot and wouldnt last long but the 416 was a good running kit. Quote
Vegas FX400 Posted March 23, 2012 Posted March 23, 2012 Heard the same as Burt. When I had my 400, I was going to do a kit on it, but instead Dan from Powerhouse just tweaked it and made it high compression.....thing ran great and you could tell the diff from stock to that alot. Quote
Just Mike Posted March 23, 2012 Author Posted March 23, 2012 Good info. Thanks Guys. I have to wait a bit either way. Might tear it down to see what it needs and then go from there. The crank is sounding a little slappy. Quote

Go to the Sparks Racing site and get a kit from them, the 416 is good and they offer all the goodies you need and even a kit.. http://www.alwaysopenmall.com/layouts/02/unsecure/lu_items.asp?SiteID=223&DepartmentID=85&CategoryID=949&GroupID=7036&ItemID=0&StartNum=1&Sort=&ShowPics=0&ListByCode=1 Little expensive but you save on labot if you do it yourself!

Little to much for my kids quad. I paid less for the whole thing. LOL. Thanks for the input though. I just hope the crank is stiill good and that will allow me some more options for the top end.
