Wierd Issue

[djstormxx]

I have some green residue on my bike that seems like is coming from a leak from the brake lever? Anyone know what it may be?

Brake fluid? Could also be some ozidation to copper washers that are used in some brake set ups.

Copper oxidation would be my guess too... or maybe algae... or some form of wax or metal polish left behind.
No DOT-rated brake fluid should ever turn green under any circumstances.

ok. I wonder where its coming from then. I did wash my bike so maybe its washing off from something.

snot rocket ???

Bingo! lol

Fork oil comes in green. Any chance you've got a blown fork seal?

[djstormxx]

Nah there still in tact.

post a pic. It could be from a copper crush washer. It does corrode and leave a green residue. The brake lines usually use something other than copper, like aluminum or tin.

I'm going to reuse this thread. So I was going down the local straight ways where I live and I max out my bike at 142-3ish for a minute or 2. Then we turn off and stop for alittle. Get back on the bikes and hit some nice banked turns. The problem is when we hit the straight ways between each long turn i would try to keep up and max the bike out. but when I got to about 135ish the rpms would start to shudder a bit and I could see the needle going back and forth over 10k. Anyone know why?


I just recently got new spark plugs, new air filter, new semi-synthetic oil, and sprayed the carbs clean w/o detaching them.

Your bike has a built in rev limiter to protect from over reving. At about 11.5k you hit this limiter, and it forces some cyclinders to miss preventing you from going higher rpms from normal opperation.

In other words... you reached the end of your top end.

Your bike has a built in rev limiter to protect from over reving. At about 11.5k you hit this limiter, and it forces some cyclinders to miss preventing you from going higher rpms from normal operation.

On the Kats specifically, cylinders 2/3 get their spark plug signal cut at some RPM limit (RPM limit changes on whether it's a pre/post and whether it's a 600 or 750). The purpose of this on any car/bike is to prevent the parts from being taxed beyond the safety margins engineered into the entire engine in terms of strengths, slop, wobble, etc., so it doesn't self-destruct on you. The RPM limit for most engines is usually dictated by the peak piston speed and the method of the valve closure (to prevent valve-float and make sure the valve closes at the right time). If you can imagine a valve flinging itself up through the tank and into or right past you, you can truly appreciate the concept of RPM limiters...

alrighty thanks guys.
