+1 If you're losing oil your bladders are either torn or not seated properly.

I have a feeling you may be building your shocks with too much oil on them. That will cause the bladders to blow out. If you follow the Drake video you should be good to go.

The big thing with the vented caps/foams is the consistency. They stay the same throughout a long race. I love them too! But you do need to be more on top of your shock maintenance. New bladders often is key.

jammin knows whats up. if it happen right after a rebuild granted you did a good inspection of your bladders and foam, you should of noticed a torn bladder. no biggie.. just gotta make sure it seats right.

i plan on going full vented caps once it warms up. sound strange for a guy to say its too cold in LA.. but seriously.. 40-50 degree's is freezing for socal. its going to be awesome in about 3-4 months.

Negative on the too much oil part. I do follow the drake video and the track I race at does not have great landings, so I run zero rebound. This keeps the truck stable on the landings. If shocks are feeling different by the end of the race I think it's more to do with the fuel weight differences more than the temperatures, etc.

I don't know what to tell ya then. I've been running vented caps for a long time with no leaking issues. Are you running the full foam compensators or cutting them down? I think running them full length could cause some issues. They really don't fit properly without cutting them down a bit and I could see that keeping the bladder from seating properly. I cut mine down to a little over 1/2 height and round the bottom off. If you've done that already, I'm out of suggestions.

I know it doesn't seem like they would make a big difference, but in long races you can notice it. It keeps the rebound consistent which keeps ride height consistent. Losi cars are very ride height sensitive so keeping ride height consistent keeps the car handling properly throughout the race.

I was just going to ask about cutting the foams down. I do cut them in half of the thickness.

Anybody running the white springs on front?

i just round the bottom edge like drake says. never had a problem..knock on wood.

I run a plastic spacer on the shock shaft between the body and the shock end. if you push the shaft all the way up the piston will come out of the shock body. which will obviously hit the bladder under full compression when assembled. I use the white plastic spacer from between the o-rings, ream it(4mm) out so it slides smoothly. that will limit the travel so it won't blow the bladder. Some will say the shock cant travel that far on landings but it's the crashes that will over compress any shock.

As far as the vented caps, I too, didn't like them at first but now after using them and getting them properly set-up, I wouldn't run anything else. Shocks are easier to build and vehichles seem more consistent and the shocks seems to last longer between rebuilds.

the Spring retainer's and Boots prevent the piston from being pushed into the blatter...Imo its more about Crushing the Blatter with the cap and Cutting the edges.

I have and inthought it took steering away. I ended up with either green or sometimes red in the front.

Shocks can heat up a lot after longer mains. I would think it's not a fuel weight issue.

Damn Frank! That's soft as hell. I pretty much always run Black up front with Grey in the rear. Not even on the buggy do I use Red often. I have on occasion used the Red springs up front on the buggy for a tight indoor clay track with basically no jumps. I don't see how you're running those springs on the truggy. That's 3 steps down from the stock Black. Green I can see but Red? I won't knock it because I haven't tried it but that just seems too soft.

Frank is just mad because Mugen doesn't use colors on the springs.

How is everyone seating their shock bladders? I take a small amount of oil on the tip of a ball allen and move the bladder in circular motion and it seals down. Is anyone putting them in the shock cap and just screw them in with the cap? Maybe I am doing something wrong here. I saw an associated video where they do that.

I install them in the cap. I have done this on all my cars.
Since I don't drive like Drake, no since in doing anything else he suggest. LOL
