Whats wrong with this Triumph speed triple?

Question

I want to buy this 2002 Triumph speed triple 955i.
I went to view it today and there are a few issues.
Firstly the gear change seal is leaking oil.
Is this seal internal or external? How to change?
Also there's a slight misfire on tick over. Its only slight but i can clearly hear it in the exhaust note. The chap said that it gets worse after its warmed up to the point it starts to jitter on the way home from work. He reckons its a plug but what else can this be?
Any other problems i should look out for?
Any good tech and mechanic forums out there?
Thanks guys.

Answer 1

the oil seal can be quickly and cheaply changed, you can remove the gear linkage and then hoik the old seal out with a fine screwdriver

being careful to knock the new one in with a deep socket over the top to ensure accurate and sound fit.

The speed triple uses individual spark systems for each cylinder; the middle cylinder coil is subject to over heating and breaking down; though this is normally accompanied by a warning light on the dash to show there is a fault. check to ensure the bulb hasn't been removed or blown as this is an indication.

In the manual there is a reset process where by the engine is started warmed up turned off and restarted, you will find it on the internet..

if the fault doesn't go then you will need to seak out a triumph engineer

consider having a power commander fitted as the engine is under taxed at only 110 HP and is capable in the daytona of producing over 145 BHP

enjoy

Answer 2

I test ride new bikes and Phil is correct. The windings in the coils break down and cause the misfire. When cold the fractures in the windings are touching, when warm they expand and you loose the build up of charge that is then sent to the spark plug, hence why its worse when warm.



Still buy it, they are easy problems to fix and Triumph's tend to be looked after.



Phil, I gave you a thumbs up, seems like answers is turning into youtube, just another forum for the sad people to slag off in.

Answer 3

the Hinckley three cylinder in all its forms is probably one of the greatest motorcycle engines ever for real world street use, love it to pieces power to weight to character including top end with loads of low torque, superb. you can be three gears too high and still grunt out of a corner and leave a hot Audi behind; even the old Tiger 955 sit up and beg, I used to call the right bar control the 'mirror emptier' The rest of their kit is also good to better than; their nuts and bolts are plated better than Hondas (source; Ride tests) and the plastic is reasonable. You do need a good service dealer, the bikes need regular service and get real hot. Luckily, many Triumph dealers feature in the UK top rider votes. Real character and usability, real fun, has that 'I love my bike' factor that the Japs rarely dial in. Saying all that I ran a new Triumph RS against a friend's Trident 750 from the mid '70s - mind it had £15000 of work on it, blueprinted conversion to one litre. OK I am a chicken but I could barely keep him in sight on a real country road, and him on skinny tyres and 30 year old brake designs..... he did used to race with Minter at Brands but that, as they say, is another story. So progress is only skin deep maybe

Answer 4

I think Phil has given you a very accurate and helpful answer - he obviously knows Triumphs!



(...and I agree with Mr. Natural - it's a sad but true fact about Y!A...)

Answer 5

Chech out www.triumphrat.net.Lots of good forums and great advice from fellow Triumph freaks!!

Answer 6

Another issue to look for is warped front disks. Triumphs around this time seem to suffer from this more than they should.

Answer 7

I don't know why anyone would give a thumbs down to Phil's answer. It seemed very helpful to me.



You know there are a whole bunch of AHOLES who go through these posts thumbing down everything. They obviously don't have much of a life.
