SV cam install experience
After doing a ton of research about doing the SV cam swap, I took the plunge. Since my '06 Wee has 45k miles, I decided to go with all new cams using Gen I and II after talking with Blair from SV Racing. It has taken me 4 afternoons to get to the point where I started the engine today. The engine spun for about 2 second and fired right up and settled into a nice idle at about 1,300rpm.....just like it did pre-swap and then began to gradually slow to 1,100rpm....which is perfectly normally for a fuel injected engine and how my engine behaved pre-swap. I haven't taken the bike out for a test ride yet as I didn't want to go thru putting everything together and only to find the engine wouldn't start or make a horrible noise and have to disassemble again. Using the idle screw, I raised the idle to about 1,500rpm's with a fan directed at the radiator while I used a stron flashlight to look for oil leaks. Found one at the front cylinder head cover where the crescent gaskets are located. Giving it a few strong raps with a plastic hammer stopped that leak. Once it hit 3 bars on the temp gauge, I started blipping the throttle and listening for any abnormal noise. Actually, the engine noise is slightly less that when I started. No ticking or clanking noises at all. Sounds like a showroom new bike. Before I began pulling the cams, I did a quick lash check and found that the exhausts were fine but the intakes were a little tight(both cylinders). I decided to keep the exhaust shims in place and go to the next thinnest shims on the intakes and see where that brought me. Worked perfectly. Now, on to the those damn cam chain tensioners. Dealing with these mechanisms caused me to spend at least a full 3 hours just removing/reinstalling these things. Both are very difficult to access....VERY! Here's a tip for dealing with the front cylinder tensioner install. First, put the tensioner body in place as best you can from the left side. Next, slide the spring up onto an extended length Allen wrench(3 or 4mm, don't remember which) and manuever the spring into the tensioner from above...taking your time like a surgeon. Once in place, use a long screwdriver to hold the spring in place while sliding the Allen wrench out of the the spring. Now, how to the get that washer in place? Use a long 3mm Allen wrench from above and place the long end into the the spring slightly, slide the washer onto the Allen wrench and let it slide down and it should go right into place. Did for me. Getting the bolt into place is next. You'll just have to use your fingers best as you can to get the threads started without crossthreading. No tip here, just do the best you can and don't crossthread.
