Re: Project Raptor Update
Oh boy, here we go.
You said that I need to get my facts straight and that the only models that had tranny problems were the 2001's. You then went on to say that Yamaha made some tranny mods in the 02's to help compensate for the torque, but most of the people that had tranny probs were the guys out there dumping the clutch all the time. Finally, you claim to know that there is a difference between riding hard and abusing something.
Now for some factual correctness. The poorly designed, slapped together weak transmission on the 2001 had a 2nd gear with 3 engagement cogs and a street bike gear ratio that was less than adequate for any off road purpose.
After Yamaha realized that the public would not accept the poor street bike gear ratios or the weak transmissions, they changes the ratios and added a 4th cog to 2nd gear. This was intended to cover up the defects but it did not. The only thing that changed is that NOW, with any power applied to the 2002-2003 engine, 3rd gear WILL explode just as 2nd gear did in the 2001. When a 2002-2003 3rd gear explodes, the entire engine goes in the garbage.
I have personally experienced a blown transmission and it was not fun. When it cut loose, I was well along in 2nd gear. Your theory that 2nd gear fails because people "dump the clutch" is a laugher. The gear ratios are so bad in the 2001 that it is almost impossible to start out in 2nd. I find that 1st gear is the best start gear on the 2001 (unless you lowered the final gear ratios for some unknown reason). As for abusing the trans or missing shifts, I have been riding and racing for years. I was concerned about the transmission so I always started in 1st, short shifted 2nd and waited to poor on the power until 3rd was in business.
I know what to expect from a transmission, especially something advertised as "YZ Spec." In this case, Yamaha has screwed the public and is now trying to blame the public for the defects in their poor design. I was at a test of the Raptor when it was presented with the current engine bored to only 600cc. It was a turd and the gear ratios were bad.
In response to the test of the 600, Yamaha elected to simply add another 60cc without any thought about the transmission. Mind you, the transmission was already under-engineered for 600cc power or the stress of off-roading vs. a street bike -- it is the same trans that was designed for the engine when it began life as a 500cc air cooled engine.
Do you remember the Chevy Corvair "Unsafe at any speed?" The Raptor (aka Craptor) is the modern day Corvair.
