2022 Kawasaki KLR650
Bingo, the KLR is simple to work on and a very reliable engine. However when people start tinkering with it get it massively wrong and break something then expect warranty to fix it. Huffing and puffing saying it was like that. If you are cracking the engine case to dona doohickey then there is risk. If you are working with cooling and get it wrong then major issues.Aftermarket parts and installations don't void the warranty. Read the Magnuson-Moss-Warranty-Act.
Now, should you install a part incorrectly and subsequently suffer an engine damage from that part, it should go without saying that the manufacturer doesn't have to cover that fault in their warranty.
Everyone has different opinions about what needs to be done to thier KLR. everyone is different and rides differently and treats there KLR differently. Just voicing my thoughts and experiences from all the Aussie mechanics and dealings I have had with them. Will say that it is definitely a North America dilemma surrounding the KLR.
One member on here, from America, did say this and I agree. Stop spending money on modding the KLR, just ride it. Get to know the bike.
Half the issues with bike owners, especially new ones is, they buy the wrong motorcycle. All motorcycles have thier bugs and issues. Just need to accept some and if you can live with them. But won't know that from on paper, get out and ride the bike. Ride it properly and how you expect to ride it. If it doesn't feel right or can do what you want it too, don't expect to modify it and make it everything you want. Try other bikes first.
