After much back and forth, I finally decided to go with the Sunline V1 MDX levers for my new 2010 YZ450. According to the Sunline web site, the same front brake lever fits 08-10 so I ordered up a brake and clutch set. The brake lever did not come with instructions...not to worry, I have changed out brake levers more times than I care to admit (yes, there is a reason I want to go with 'unbreakables' right out of the gate ). So I am thinking "how hard can it be"? Well, either I am missing something obvious or..well, I must be missing something obvious. I took off the stock break lever, no problem. As I went to install the Sunline, I noticed the lever did not have an indention for the pin that runs into the brake cylinder; it was flat. The way the stock lever is designed, the pin that runs into the brake cylinder has a round hole about 1/8" deep which allows the rounded pin to nest inside creating a locked in fit. The Sunline does not have this same indention which raises two issues: 1. With no depression for the pin to seat into, I am unable to get the lever to line up with the mounting holes because the pin is too long. 2. Assuming I can solve issue 1, I am a little concerned with a round pin head butted against a flat surface. Having the depression on the stock lever created a nesting that pretty much locked that pin in place so there is no way it would ever slide out. Not sure if the round head against a flat surface opens the possibility of the pin sliding out. I checked the sunline website for installation instructions hoping for pictures or directions but came up empty. Has anyone else run up against this? If so, how did you solve it? Does your Sunline have a drilled out depression similar to the stock lever and they just packaged the incorrect lever? The model number on the packaging matches the model number on the Sunline site for a 2010 YZ450. I tried to be as descriptive as possible but can send pictures if I did not do a good enough job describing the various components. Thanks in advance for any help.
