all in all it seems to be going alright. It's growing on me, which is a good sign.

Reverse seems to not want to go back to fwd half of the time, I lubed the cable and that helped for a few cycles and then it's back to it. I'm just going to minimize my use of it, maybe even take the linkage out.

and i finally found the rattle, broken exhaust mount.

I should be able to get out and do some serious time in the desert to fully break it in, hopefully the top end will open up a little more and not seem so strained. i think the lighter roller fix is in my future.

i did the first oil change and it looked clean but awfully light. i'm going with dino 10w/40 for the first change and then go synth. Is there a problem with heavier stuff, i have some mobil 1 15w50 i was planning on using..

You're right pghruby, the chassis is settling.

yeah i've done it both ways in the past for different kinds of engine, but the little sucker runs less than a quart in it and pulls me and my son miles out in the desert- so I figure it deserves the best.

It did well saturday, climbed most of the hills i pointed it at. went down some crazy downhills that were basically short cliffs, i was quite surprised. I think it's bogging a bit at high rpms because it's not breathing well. gonna hit AB today and get one of those beer can filters and see how that does.

Open up the exhaust and the buggy will come to life... Very Happy

I had the same problem with top end and just gutted the exhaust and it went away...all you need is a hack saw Twisted Evil

jonsonjonson has already found some great ways to eliminate the bog problem also:D and the mods are cheap Very Happy

Erci (BIGE) carries a lot of the parts at his store Very Happy

Yeah I figured that would be next, though I really like it as quiet as possible. how much louder did it get for you? did you change the carb setup too?

Here is a link that has two videos of my buggy running...It is not two loud, but if noise is a issue you can also buy a slip on that will do the same thing with out the noise which Eric also carries at his store Very Happy

I did try two jets...I started with the 130 jet with a UNI which would bog than go which means I need to step up the pilot jet, if using the 130 setup...than I ran the 128 which would not run with the uni and did ok with the stock air box...but I ended up putting back on the stock 116 jet...the kart seems to perform its best with the stock Jet and open exhuast. I am plaining on upgrading my CVT with some new springs and rollers soon Twisted Evil

seems that makes a huge differance on these style karts...but I think the kart does very well for stock, The exhuast is just very restrictive...I lost my camera, other wise I would snap some pics of how restrictive it is Evil or Very Mad
