It is also much stronger and secures the inge pin brace better as well.

Check and make sure the correct screws are in the lower bulkhead. I have seen too long of a screw protruding into the diff case and binding the gears.

Its always best when buying a used kit to completley dismantle and rebuild it. Never know what someone else has done to it.

Great point! I accidentally messed my front diff on my first YZ4 build not payin attention when adding the aluminum camber blocks, thus put the wrong screw in.

Looks great. I am also looking forward to seeing the LMR/MR33 collaboration per their YZ4 body. Not sure when it will be available.

i wonder if the side pods of the jc body are higher or lower than the original body?

That is a good question.

Appears to be close to the same. The majority.of changes in the rear centre area.

Sounds like Lee Martin wasn't really happy with the YZ4 in the EOS at Hudy Arena. Something about landing off the jumps. Anyone experienced it?

I am guessing he can't gas it immediately after landing a big jump...

I have not had this issue and have not heard of anyone having this issue however that does not mean some issue arose causing the problem. Lee has had some big wins and great finishes with the YZ4 both on carpet and dirt. EOS last year he was on fire as well as grabbing 2nd at last years Euros in Valladois, Spain (large out door bumpy dirt track combined with carpet). Possibly the issue was do to using the protype shorter chassis (front half I heard was shorter) thus heard larger pulleys are used in this prototype, however I am not certain. Guess will find out what was the cause of the problem here soon.) Could be a bunch of potential issues that causing the problem. Definetly not am existing issue with the YZ4 at least one that I have not experienced nor anyone else I know whom runs the YZ4 has ever mentioned.

Possibly it was something to do with the slipper, they were losing time to the XRAY coming out of corners & did something with the slipper to help that. Lee said that then "caused other issues".

Possibly had it too tight & with the high grip carpet, punching the throttle on landings, probably upset the car.

Makes total sense Jonny. Probably an isolated incident as these have been really g2g. Quite incredible for such a unique platform, thus really different than most all the other platforms. The SRX4 is quite unique as well.

Mine would Wheelie after landing if the slipper was too tight

yeah probably. I mean 5T motors gotta be wheelie machines (which is what mine has when it used to run carpet).

Maybe some guys who went to the EOS can also chime in
