Just take the air cleaner off and get a visual while you set the epa.

Run the outer camber link on the top inner hole on the hub (hole 3 on setup sheet), and on the 5 hole tower, you should be on the 2nd hole up from the bottom on the inside row (hole 9 on setup sheet), or even the next hole up (hole 8). The lowest hole, #10, is really meant for ultra-high bite tracks and I've never really liked the feel of the car w/ the rear roll center in that location. It really unbalances the roll axis, but that's another topic for another day
thanks for the tips, sean
I made all of the camber link changes, checked epa, and went up a tooth on the cb..buggy felt great today. finished 3rd in mixed sportsman/pro buggy ..second time racing nitro, I'm stoked!
can't wait till next weekend

Hi, I broke an outdrive on my 2L old TKI3, do you think it poped the shaft a bit and being bigger shafts, broke the outdrive.
Also my driveshaft end pins are wearing alot for only 2 litres.

I dunno what Kyosho are doing, it's starting to look like they have now over hardened the outdrives. Mine snapped inside the diff casing. It snapped the shaft of the outdrive inside the diff case bushing clean in 2 last race meet. I've never seen that one before on any car..lol

I snapped an outdrive last weekend as well. Right outside the rear diff case, not the lightened areas as one might suspect. A friend that is a machinist thought it was probable that the heat treating was faulty as the part seems a little on the brittle side.

This was on a TKI3, first race on the car.

I was going to get a TKI3 but thought I would wait to see how reliable the car is first. Looks like it was a wise decision. I'll just keep my TKI2 well maintained for now as it will take Kyosho another 6 months to sort this mess out Could be the stronger less flexible axles breaking the outdrives. I wonder if they will do a recall on the batch of outdrives produced with the problem?? Of course not, what was I thinking.

If they made the 92mm axles it might not be such an issue as the dog bone is farther in so less leverage on the the outdrive. Try using 93mm axles to avoid the problem. I was gobsmacked to see Kyosho staying with 91mm axles for the TKI3, surely it cant be that hard to make 92mm axles.

And the angle drilled pistons supplied with the TKI2, they were a flop, no one uses them and they know it so to get rid of them and make more sales of the white 1.3mm pistons they put angle drilled pistons in the kit knowing that us suckers will need to buy the white 1.3's

Dunno if the HD driveshafts are causing the problem coz if they were, one would expect that the same breakages would have been happening right up until now with people who run the captured unis, but I haven't really heard of anyone blaming them on outdrives breaking? Just a thought.

Definitely agree with you on the shock pistons - absolutely crazy that they still spec the ones which nobody uses.

Hi John,

Thanks for asking, didn't do very well but since it's my maiden race, I'm quite happy with it.

I could have managed to get bump up to the higher main on the final, was going second and drop to fifth and maintaining it till someone t-bone me and the race ended.

Got number 76 out of 90 No where near you experts here.

Today was practice and I got to run my brand new MP9 TKI3 e for the first time. This buggy is dialed!! I'm drinking the koolaid. Ryan Maifield w/ Jason from JConcepts, Billy Easton, Anthony Mazarra, and other factory drivers were there practicing. No Kyosho factory guys though

101% agree on this! Even if you where to buy the shock sets, it still come with that piston which of no use! To say that it's already been done with TKI2 is acceptable, but still doing the same with TKI3 is way too much!

Is anybody using the CSI shock pistons?? I've seen people running them in other brands and was wondering if they are worth giving them a shot
