I haven't had time to write much, but now the situation has changed.
As a reminder- on march during a trip I noticed suspicious noises coming out from the rear left-hand end of the engine- something like audible grinding, especially when riding on higher gears, along with a rattle at 2800-3000 rpm when decelerating.
I was freaked out (bearing in mind known cases of faulty TDU bearings) and made instant decision to dump the bike at the dealer's (this dealer besides being official Triumph dealer runs the workshop well-recognized for its capabilities- from time to time they fix mechanical things in Ferraris and other exotic stuff )
I had been visiting them every day to see the progress with the bike- whole bike was stripped down with the engine removed from the frame. To my surprise TDU bearing was assembled in a proper way (rubber collar facing towards the rear of bike) and didn't show the symptoms of any wear (mechanics at the workshop showed me this bearing and it didn't have ANY lash- they were puzzled, cause even some of the new bearings have a little, yet noticeable lash).
Then came my decision to check every bearing in gearbox (both input and output shaft inside the engine), because TDU bearing was perfectly okay. At this point I could not turn back. Engine interior was clean and everything was tip-top. Guys inspected the gearbox, but all the bearings were super tight :roll: Also, branded by Koyo. However, they "didn't like the way the gearbox was assembled and didn't like the 5th gear washer".

After 15 days in service I picked up my bike and was surprised- shifting appeared to be more smooth- absolutely no CLUNKS when shifting (before the gearbox inspection shifting into 2nd gear could sound like an explosion :x but I kept saying to myself that this is just a feature attached to this bike), and from time to time LITTLE clunk when the first gear is engaged. Overally- shifts like a sports bike. However, one annoying thing still remains- sometimes its hard to get into 1st (I have to release a clutch a bit and the put a pressure on gear selector to make sure that 1st gear is sitting tight), which can sometimes pop out - but I think it's normal in Rockets.
All in all- Even though there wasn't any single faulty bearing gearbox strip down and assembly cured the bike. The guys at the workshop didn't utter directly what they meant by saying "assembled in improper way" I kept pushing them but the only answer I received was "They didn't like the way it was assembled". Strange.... maybe they were "politically correct" didn't want me to know too much about the Triumph assembly quality? :twisted: :twisted:
 
Good to hear your back on the ride. I hate mine being down during riding season. I actually like working on her but I wish she would break at the end of season not during.
 
New pistons and liners and and a few monitoring upgrades, some ceramic coated pistons, and she is running like the beast she is. I am waiting on a new style set of clutch fibers to test run and give feed back to the company. there is suppose to be a lot more fiber contact area then the stock Triumph ones maybe this and heavier springs are the middle road between stock and lock up style.
Who knows they might hold up one thing for sure I will put them thru their paces :evil:
