White froth on dipstick

Any ideas?

I have the white froth also. I replaced the petcock with the raptor petcock (less than 1k miles ago). I have also used a rebuild kit from kientech when I installed his jet kit. What else could be letting gas in?

Any advice is much appreciated

The bike is still in the shop so I don't know if its been road tested or just run in the garage.

I'd rather have the correct pilot jet in there and have them fix the problem with adjusting the clip, BUT if making the pilot jet hole larger makes it run fine and it won't cause any grief or harm then I'll be happy with that as well!!

Thoughts....?
UPDATE:

Spoke to the "mechanic" today. Turns out he is not a licenced bike mechanic (no surprise there, he was working on a lawn mower when I met with him) and he thought I had the lean surge problem at roll on $%%&&%!!!!! I told them the lean surge happend at constant throttle settings; when I went to full throttle/goosed it the lean surge went away!!! He also said he could not get the bike to idle when it first came in that was why he drilled out the pilot jet hole. I find that strange as Jesse had cleaned the carb, I only rode it once with fresh gas and I ran it dry with fuel preserve in the tank before storing the bike for winter. The "mechanic" is going to re-road test the bike and try constant throttle settings if that works then we are good to go if not he'll install the stock pilot jet and try richening up the jet setting.

Adjusting the clip affects ~1/4 opening, whereas changing the pilot jet affects ~1/16 to 1/8 opening, so you need to isolate during what opening the problem happens so you can address it with the correct circuit.

Surging is not inherent to CV carbs. It is a tuning or wear issue. Which brings me to the next questions:

How many miles are there on the carb. When did the problem start happening? Has it always been this way? Did it start happening suddenly, or did it progress gradually?

Regards,

Derek

Fork oil recommendation....

1993 dirt model, stock suspension except for much bigger springs. Don't know the spring rate, but they but they are big enough to have only bottomed out once under my 250lb. physique, and that was getting a lot more air than I intended and landing a bit flat...
Just looking for the smoothest ride possible on rocks, roots, water bars and washboards. Don't care about racing speeds or jumps, only a smooth ride in the rough stuff. What weight oil would you think works the best? Quite a bit thicker than the 10 wt stuff recommended in the Clymer's manual or not so much?

Also Intiminators? Cartridge emulators? Whch gives the smoothest ride? Would the modern forks off an RM or something ride better?

Is that cracking due to not using the decompression mechanism when kick starting it?

There's plenty of those scattered on Maximum-Suzuki. I will say the one thing I couldn't find an answer to was why the steering stem wouldn't press out of the clamp. On the 99 USD forks here's why:



The step keeps it from budging. By pressing on the threaded end of the stem with 5000 psi showing on the gauge and a loud POP it started to move.

Glad you got it out. Did you already press out the DR stem. That is the hard one.

Yes, but it's a borrowed picture from someone else in this thread. I was wrong, no crack. Still need to find out what's up with the kickstarter. The way the shaft was wobbling around I thought sure it was cracked until I got the clutch off to see, no cracks. So no parts bike, hopefully.

What causes it to crack? Not using decomp when finding tdc and then kicking?

You dont kick it with decomp i think

I think if it kicks back when you are at top dead center it puts enough pressure on the kick start shaft bearing that it cracks. Seems like a wimpy design to me.
