wee-wee404

Okay, the head is off, what am I looking for?

I have checked the trans oil to see if I could see any antifreeze and haven't noticed anything at all. If you're familiar with engine ice then you know that it has kind of a smell to it, not real strong but some. I haven't been able to smell anything nor have I noticed the oil draining out "less thick." As far as the leak down test goes, the complete motor, carbs, reeds and exhaust all came together and off of the same bike. I got the motor from a buddy who put a 600cc crotch rocket motor on his banshee and the guy he bought it from claimed the 404 n what not. In order to perform a leak down test, what all would I need? If I had to bet, id bet that it is leaking from the cylinders because that is one of the few places I didn't look for to leak from. You think that would be a spot where it would dry up quick enough not to notice? Thanks guys

Hello everyone, I am a fairly new banshee owner, owned it for a little over a year now and new to bansheehq. I built mine from the motor up just because I didn't want to make payments on one and wanted it to be exactly how I wanted it to be. After I finished tightening the final bolt I took to my mechanics shop and had them make sure that the jetting was right along with everything else, just to be sure. Everything has been going really well with it so far except that the coolant keeps going down on it and drastically. After 3-4 rides for around 1-2 hours at a time, the coolant is significantly depleted. I also have a 04 yfz 450 that I own and bought before the shee. I have always ran "Engine Ice" in it along with a boyesen super cooler. So, naturally I bought "Engine Ice" for my shee. I put a small amount in the overflow bottle and fill the radiator up until its full. While riding I have tried to watch very carefully to see if I notice a leak or steam or anything of the nature that would suggest a leak and I cannot find a thing. I have let it idle for 15-20 minutes on the concrete and again watched for leaks and still I cant find a thing, any ideas? Im afraid I am going to run it out one of these times and really be in trouble, not to mention that Engine Ice is pretty expensive!!! I have FMF fatty pipes and silencers on it along with K+N air filter's and that's all I know of since I bought the motor already assembled. The guy that sold me the motor also said that it has a 404 big bore as well but I really don't know for sure. Any help or suggestions would be appreciated, thanks.

I use a little "mouse" hand sander with very fine sand paper, short swooping strokes and very little pressure. Once thats done theres this stuff that you can buy in an aerosal can called "plastic renew" and follow the instructions from there.
