Title: 2007 ls650 piston from Wiseco Post by JazzyMutt on 06/20/13 at 11:04:39 i have a 2007 ls650, the bike was running great and i like it a lot.  i live in south texas and it gets really hot.  i was driving home when my bike quit working.  come to find out that the piston cracked, so i am looking for another one to replace. i was looking at the Wiseco piston 97.00mm one, but when i talked to them they said that piston might not work from a DR to an LS,  i am having a very hard time finding any information about a 2007 ls. i talked to the dealership and all they offer is a .5 over sized, so that piston will be 95.5. i plan to keep this bike for a long time if i could, so any suggestions would be really appreciated. thanks

Title: Re: 2007 ls650 piston from Wiseco Post by Dave on 06/20/13 at 17:20:44 As Verslagen indicated, the stock Savage piston is 94mm, the stock DR piston size is 95mm.  If you decide to put in a Wiseco you will need to rebore. You may have a cracked piston.....but it may not have damaged the cylinder.  You won't know until you pull it apart. I installed a 95 mm Wiseco in mine, and I love it.  You will probablyget a little more power from the 97mm.....but the 95mm is plenty strong.  I did get the silicone Carbide treatment on the cylinder wall...maybe that would help you with your Texas heat issue.  If you get a Wiseco....make sure you get a reliable company to do the boring.  One that knows what they are doing.....you only get one shot at it and it has to be done right.

The 1996-present DR650 pistons are the ones that will NOT work in our engines. Also, Wiseco no longer manufactures the 97mm size for normal stock; it is only available when ordering 12 or more as a special order.

You can get the cylinder resleeved at a price $$$

Where did you get yours bored, and silicone carbided?
