Maybe because it got a five star rating, not sure the pics aren't that cool or what I did to deserve this, these spamers think it's like a 5 star hotel where caca roaches check in but TNT ain't let em check out!

I've got good news and I've got bad news. The good news is the kid went out to round 1 of the ITP Quad Cross and took 1st in the Open Expert Class. The bad news is within the first five minutes of our first practice following the race, the clutch basket went critical mass and detonated. It lost five ears and shredded two of the friction plates. Fortunately I don't think it did any other damage to the motor. Interestingly, upon inspecting the whole clutch assembly I noticed that all of the rivets connecting the drive gear to the basket were stretched and very loose. It literally had about 1/8 to 1/4 inch slack between the two. The rivets were very close to failure. In looking at the rivets, I wonder if the basket failed because it's a POS or if it failed because the slack in the rivets caused it to overstress and break? Anyhow, in case anyone is wondering, this is my dune bike and not our primary race bike (The primary is getting 3rd gear replaced). As such, this bike has less than 30 hours on it and has only been raced a total of 6 motos. As has been stated on this forum before, you just cannot tell how long these baskets will last. The irony is I was planning on replacing this basket in a few weeks. I was just waiting on getting the Son's bike back up and going before jumping into another project. Oh well, what's one more project.

On a very positive note, the kid pulled a nice holeshot with a stock motor against some very built up LTR's, TRX's, and YFZ's. Complaints about the performance of this engine are greatly exaggerated.

this quad has to be rode differently then most any other quads out there, which inst a bad thing but you do have to know how the clutch feels and how to launch it the right way

Wow! Well first glad he is ok! I was just talking to Warnert yesterday about this clutch we all know even the updated version is NO GOOD! Rivets are not as strong as bolts and they are in shear from high spinning torque loads, as you can imagine even the smallest piece of clutch plate hitting soft casted AL will fail every vertical wall in it's path and the longer it runs the worse it gets....glad you escaped internal damage. Ours failed about the same hours.

Make NO mistake thier is NO riding technique that will prevent this failure that results from a poor design. If you do not upgrade to a billet basket you run the risk. I'd recommend BCS since they use bolts vs rivets plus they put a surface hardening chem finish on that the pourous stock basket does not have, that coupled with a machine cold worked strong billet of a higher grade al will not fail no where near as easy from a plate impact in compression along with shear loads from the bolts on the basket web to hard steel gear interface.

We're running local expert today w/stock basket waiting for our BCS basket next week, hope it holds up.

BCS is just waiting for them to get done w/chem treat....they machine them themselves.

i didnt say that any riding technique was going to keep you clutch from failing??? i said that to the fact that most people think the ds450 is under powered and how he was getting the hole shot??

I had to make a decision yesterday between a BCS basket and a Hinson basket. Since Hinson had them in stock and they also have had them in production for a while I decided to go with a Hinson basket. BCS should have their new baskets in stock any day, but with us having a local race in Phoenix next weekend, time is of the essence.

Gregory you are correct as well. Technique is critical to making this bike, and every bike for that matter, perform well. Robert used to be good at starts on his bike. After spending two days with Joe Byrd and getting a few tips from Can Am ProAm rider Cole Henry, Robert is now very good at his starts. After two training sessions with Joe Byrd, Robert's lap times on the same track decreased by 10 seconds a lap! If you want to invest your racing money wisely, put down $500 and spend two days with Dr. Byrd. That $500 bucks will make your bike go faster than any other upgrade you can put on it.
