New to the forum. Just purchased a pair of 2004 GP1300's with about 100 hours. Did my homework and feel good about them. I have been researching the block off kits and premix issues. My question is, any new developments in 2004 or is it the same oil pump issues with the lines coming off and failure with engine seizure? The previous owner knew nothing of the conversion to premix debates and thought I was crazy to convert to premix. If it's still a concern, is there a good DIY on the conversion with pictures? Would really appreciate advice as I am nervous every time I take them out.
