Better Motor Mounts for a GPX 433?

[thunderjet440]

I just broke another set of mounts on my sled,this time the rear ones,does anyone make a stronger mount,maybe a solid one? thanks

sounds like you have a mod sled here with lots of motor twist going on.
we made our own solid teflon/plastic mounts for my mod srx. we also installed a bombardier torque arm to help keep the motor straight.

I am probably going to add some catches for carriage bolts, something like the Sno-jet SST F/A uses and make sure there is something solid the whole way through the mount. I'm also putting a torque bar right in behind the clutch and bolt it to where the oil pump holes...similar to how a Rupp Magnum or Nitro L/C is.

My OE ones were iffy so i replaced them,nohing but problems with the kimpex units, or whoever makes them.
snopro,where did you get the teflon to make your mounts?

 

[snopro]

i got it at work (pulp/paper mill). but i suspect you could get it from any machine shop.

i started using aftermarket HPE "high durometer" rubber mounts in my sno jets. there meant for polaris indy wedge chassis but fit the sno jet mounts good. IDK if the yamaha mounts could use something like that.
