Sunline Shifter Mod

[Tire Torcher]

Well I have had some time to put a few miles on this shifter mod now and have to say; Why did Triumph not do this from the factory? What a difference. No exaggeration, I have not had a missed shift since I put this shifter on. Even the odd time where I have been a bit of a ***** with the shift action, it slips right in. 1-2nd, 5-6th makes no difference absolutely positive action. I can't remember who it was that came up with this mod, but thank you thank you thank you! I highly recommend it to anyone who has had the slightest issue with missed shifts. Biggest bang for the buck ($28.00) upgrade so far.

Love mine too! Shifts very solid and never had a mis-shift after installing it.

I too have done this mod. I think it is worthwhile but it does not come without compromise. The sunline is not made for the S3. The peg breaks away in the wrong direction, so in the event of a low side your screwed! It will rip off your transmission shaft! I think this is why the Triumph engineers designed the multi linkage setup...it will prevent the input shaft from being harmed in an accident. Also, the design limits any lateral forces on the shaft. I track my S3 often, so I'm probably going back to the 'safer' factory setup. After all, if you spent over $200 on sliders to prevent damage, would you keep a shifter that might $everly mess up your tranny if you low side?

Scary thought, I'd be interested to hear from someone who has done this mod and then dumped on the shifter side. I have dumped a lot of dirt bikes long before folding levers and never seen a broken shaft, but I suppose it's possible. I would hope the aluminum would just bend before the hardened shaft would break, especially with the drastic outward reach of the Sunline shifter.

I also think the aluminum would bend way before a steel shifter shaft would break. I've also gotten the false neutral 5th-6th a few times now even with the new Sunline shifter. Of course I wasn't shifting like a boss when that happened. I just changed my oil to Castrol 20-50 fully synthetic motorcycle racing oil from the Triumph Mobil One. I'm looking forward to see if I can notice any difference with the oil change.

Thats what I was thinking. The standard set up is also infinitely adjustable.


QUOTE=lospice1;1945057] I have no idea why Triumph did not design and implement the shifter in this way. Seems to me a direct linkage is better than ball joints.


I think it is ( the original setup ) to minimise on leverage on the selector shaft itself, by putting the one piece lever on it, it increases the " side push " on the slector shaft .The old 955 Tiger had a long selector shaft that was supported outside of the gearbox by a plate with a hole in it before the one piece selector lever.Is the replacement lever that you are using designed to be fitted backwards, just thinking about the way the ends are meant to fold backwards if they come into contact with anything ?

I took the advice and just installed it last night! 100% improvement in shift feel and quality!!
