Do you know how the different lift and duration specs will affect your OEM valves and springs? Just making sure you're not biting off more than you can chew. In general, personally, I'm not dropping in a new cam without also doing a new spring kit, hardened spring seats, Ti retainers and proper keepers. There's a good chance valve train life goes to **** otherwise.Just purchased a hot cam off Ebay costing me $35.33 shipped partnumber 2027-1 it fits the klr110 and drz125 there was 3 more advalable as of July 4
