That's a **** shame, sorry for your trouble. It's not typical to have this much problem with Triumph.
If it was me, I'd fix it and ride it. Obviously it should have been immediately returned to the dealer if it wasn't fixed right back then, waiting over a year to go back is probably why they won't honor the repair warranty.
But based on your usage, (2000 miles in 4 years?!?) you don't ride it anyway. I'm actually amazed you still have it since it seems to just be taking up space.
My suggestion would be to fix it and sell it to someone who might ride it more. It's going to be near impossible to sell in it's current condition.
Good luck and I hope you can get it made right.
Well, just so all the info is out there....
Bought the bike in July '07...rode it for 650 miles before Wisconsin weather closed in (it turned out to be the snowiest winter on record in over 125 years)
Took a new job in NJ in March, '08. Wife stayed in Wisconsin while the house was on the market. House sold in June and bike was shipped to NJ (along with our other 2 bikes) and sat in a friends garage while buying new house and moving household belongings. Bikes finally at new house in August, '08. Managed to put only 400 miles on the Rocket before NJ winter. Rocket shifter was not returning to neutral and hanging up. Rode bike to dealer 70 miles away and on the ride there the shifter started acting normal. Mechanic could not find any problems during extended test ride. .
2009 was a normal year. Rode the Valkyrie to Americade and the Rocket around town. Put 4000 miles on Valkyrie and a 1000 miles on Rocket...Bikes laid up in October for NJ winter (snowiest winter in memory for NJ). Rocket started jumping out of first gear just before putting it up for the winter.
April 2010, took bikes out of hibernation and Rocket wouldn't stay in gear. Took bike to new, highly-recommended dealer and they verified the problem. Mechanic talked to Triumph HQ and they suggested disassembling clutch and looking for issues. Dealer reassembled, bike still jumping out of first, and got the authorization for the "Update Kit". Bike dropped off for repair on June 4th.
June 7th, had spinal surgery to fuse spine. Has fractured L5, herniated L5 disk, and bulging L3 and L4.
My Son rode the bike home 9 weeks later. On the ride home, the bike wouldn't stay in first gear under any throttle position. Parked bike, numerous calls to Triumph and dealer and got the word Triumph would not do any more to address my problem.
So here we are, 2011. Still not riding and still recuperating from back surgery. Had a friend bring her trailer over and we loaded the bike and took it to the new dealer. Head mechanic wanted to go back in to the clutch to see if it could possibly be something overlooked/simple. It isn't. New dealr spoke with Triumph HQ and they re-iterated that they are not willing to do anyting more for me. Any repairs are strictly on me.
As you can see, there's been a long, sad sob story here. Not looking for pity, but just a few more perspectives.
I have a 1999 Valkyrie I've had since new that has been no trouble, been coast to coast several times, and ridden in 26 states so far. The Rocket was a second bike for fun and it replaced a Yamaha Warrior that was only 14 months old a the time I sold it to buy the Rocket. I blame the test ride at the Honda Hoot (on our honeymoon...my new Wife rides a VTX) for the impulse. Bought the Rocket within 3 weeks of returning home.
So there it is....do I absolutely need the Rocket, no. I'll never sell the Valkyrie anyway. Just wanted something to fill the need for speed and acceleration.
Thanks for putting up with me....
