This basic kit only has the doo, torsion spring, and drill bit - does not include gaskets or the special tools. If you need more than the basic kit, put the word "complete" in the search box without the quotation marks, and youll see the kit with gaskts, or with gaskets and the required special tools.

The famous Eagle "doohickey" aka balancer adjustment lever. Machined from solid 17-4ph stainless stell that was heat treated to H900 condition. This is the strongest and best doohickey you can buy. There are copies, but none are as good. We have hade small improvements since the first one was machined in the early 2000's.

Now includes the toirsion spring. This is absolutely the best setup for adjusting your coiunterbalancer system in the KLR650 engine. The torsion spring has these fetures that the extension spring doesn't:

Captured on install

Takes the slack from the system in the best way

Does not constantly stretch and relax while the engine is running

Must longer adjustment arc compared to extension spring setup.

Much more even tension as the system adjusts.

The rotor bolt is also considered a one-time use part, so be sure to order one of those.

You will need special tools to complete the install. These are available separately or in the complete kit. Installation instructions:

Select either the 2008/9, or any other year option from the drop-down menu. We need to know if it's a 2008 or 2009 so we can include the spacer for the deep hole issue. All 2008 and early 2009 engines have a deep hole issue in the left side outer cover. I'll include a (free) bushing /spacer for this. (last five of the VIN 20800 or below).
