Engine Vibration continues

[LAS VEGAS DAVE]

Mine is smooth at any rpm. Maybe its the luck of the draw or maybe the new ones have changed something. Mine is a 2015. If it were my bike and it had a vibration that they couldn't or wouldn't fix I would also sell it. If I rode another Triumph and it didn't vibrate I also would have bought a new one, but I would ride it before I paid for it.

Hi everyone

New Update re rocket 3 engine and clutch vibration

Left my bike at Team Moto and the Triumph Rep from Melbourne flew up. His name is cliff. As helpful as he was he did a bit of fast talking and told me that they would dismantle the bikes rear and replace the shaft, knuckle and drive shaft.

I questioned him about the crank and he could not give me an answer. I informed him that I was very disappointed that when the bike was pulled down to the extent that it was they didn't send the crank away for checking or balancing especially when I offered to pay for it. He adamantly stated that there was nothing wrong with the crank. However he wouldn't bet his house on it and we wouldn't have been having the discussion about the crank if it had of been checked. He continually reassured me that they were there to help resolve the problem or should I say, my issue.

They would not except that it was a possible manufacturing issue.

However I have spoken to guys who own R3's and there's is as smooth as silk.

Even after all their work on it a vibration was noticeable at 3500rpm in every gear.

Well that's the crank. I built enough engines to know. I also fail to accept that it is torsional vibration. This is their professional wash out. Torsional vibration does not disappear when slightly depressing the clutch. Torsional vibration is prevalent at various RPM's and the rider should not be capable of changing that.

I have traded the bike. I wasn't prepared to have it off the road and put up with trial and error and excuses.

New Rocket 3 arrives in August. Better be different than the last one.

Size does matter

If you want good Triumph servicing try Olivers Motorcycles at Moorooka. Excellent staff and excellent service

I have heard Olives Motorcycles are very good with Triumph.

This vibration is not that bad its the fact that it can be stopped by taking up the slack in the clutch cable the ROCKET is smoother than my HYABUSA and all the V twins Ive owned and all the vertical twins also AND my modded Carpenter Rocket is smooth and doesnt have the vibration

IMFASTTOO, you are correct if the free travel is taken out of the clutch cable the vibration disappears but those who have adjusted the free travel out of the clutch cable they ended up with other clutch problems later.
What is technical reason why the no clutch free travel fixes the vibration.

Taking up the slop in the clutch cable puts pressure on the little lifter piece, that can sometimes wobble out of center when there is the correct slop (clearance). It wiggling causes no problem at all, it's just the way it is. The whole design of the clutch assembly could have been a little different, but it is what it is. Now, on the other hand, my 2013 picked up a vibe, all at once, while driving. I put the info in another post somewhere. It was so bad, and sudden that I got off the bike and did a walk around, look see. Had it to the Dealer under warranty, they said it was fine, only took it to 60mph as that's the legal limit here. Vibe still there, I just ignore it. It's not bad, it's just it went from "silky" smooth, to having a slight "buzz" at certain rpm's. Like was said above, could well be the counter-balance shaft.

Also 2011 is when I noticed a change in the lifter piece but it started on the touring first I do not know when the reached the roadster motors. Anyway the difference in the head size can also make a difference. Either way with the clearance in the input shaft so oil can also flow by the lifter piece and add lubrication plus the free play they do rattle some. IMO the smaller one rattles in the lifter shaft more because of the smaller head. But that's just my opinion.

2015 Rocket X at 23,000 miles and runs smooth through the RPM'S. I would be very concerned if the bike developed vibrations.

I think the lifter parts are kept on center and dont flop around and cause an imbalance but you must have some free play or you will damage the lifter

This is a very old thread but I wondered if there has been any progress is knowing what causes and how to fix the vibration.

My Rocket has done 25500 km now, the vibration has not got any worse but is very annoying and I would love to get rid of it.

Mine has done over 30000 and still does it. Exactly the same no better no worse.
