Hello all, I am a new member on PilotOdyssey.com but I have been reading a lot of the forums for a few years. Right now I can say that I can't believe I haven't become a member sooner. Anyways I have a few questions but first let me explain my situation... I purchased a FL350 about 4 years ago and planned on getting it running and having a good time . I didn't take long before I changed my mind about running the stock 350 Engine and putting in a '98' Rotax 670. After 4 years of reading threads and attempting to retain as much wisdom as humanly possible, my dream buggy came to life!!! . So... About a month ago, with a total of probably 15mins of ride time my brother hit the slightest jump and upon impact with ground broke both U-Joints and bent one of my $950 WorksPerformance Shocks. I should also mention we replaced the original U-Joints with U-Joints from a measure comparison at NAPA auto parts.

1st Question) Am I an idiot for not reading the forum on U-Joints before driving 670/Odyssey?
2nd Question) Where do I go from here...? Do I buy U-Joints from chucklenuts at aftershot motorspurts Motorsports which cost around $200 per Joint, or buy used Drive shafts with stock joints in them?
3rd Question) Is there anything else I may want to consider before going through this painful experience again?

P.S. Happy Independence Day!!! to all Americans on the Forum

Landing with the power on even with the stock Engine will waste the axles... With the twin in there your lucky gears did not see the light of day. Must let off the throttle before touching down.... Need to build a set of "shock savers" some people use chain (Canadian Oddy), I use tie down straps and it saved my shock once...

U-Joints:
I get them here: https://www.powertrainindustries.com/ca ... wnload.htm
Download the catalog. It is part #9951-22.
Forget about used drive shaft as they are real money. Try to fix yours first. You also should get a 20mm reamer to do this job (I have). It is real easy to damage the caps during install if everything is not aligned and burr free.

Shock savers:

This is a must in my opinion. I think you already found out the expensive way. By the way you can straighten that shock shaft. I have done it. Depending on where is bent you make or get two V blocks. Then get some channel iron and make a small press and use a 1 ton bottle jack. Might save you $900 bucks. You may have to remove the shock shaft first depending on where it is bent. Then put a dial indicator on it and roll the shaft. Repeat. Repeat.

These machines were not meant for that kind of horsepower.
You also posted this in the wrong area but Hoser will probably fix it.

How goes the rebuild, updates?

that's a shitty deal..but its fixable..either by straightening or replacing the shaft. the shock saver is one thing i still need to build..
i bet the 670 rips any video of it
