Question about 2008 Triumph Triumph Bonneville

Bonneville T100 Gear Change


I have a new 2008 Bonnie T100 - about three months old, 1500 miles on the clock. I ride in all weather, which here in the UK means it has been very wet.

The bike has been for its 500 mile service (about 6 weeks ago), but lately the gears appear to be stiffer than they used to be. I wash the bike regularly (every 2-3 weeks), although it sits outside overnight (under cover most nights, but sometimes not) and sits out in the weather when I am at work.

I have recently adjusted and regularly lube up the chain, so any noise a change of gear makes is not down to a loose chain.

When I change gears, the gear box seems to make a loud cluck/thunk (but not the same thunk associated with a loose chain) everytime I change up or down. It is not horrendously loud, but it's louder than other Japanese style bikes I have had in the past.

Am I being silly or is this normal? Or am I missing a trick where I need to be checking oil in the gear box or something?

Anyone offer any advise?

Do check if not drain and refill the gear box, but check with your dealer that it will not affect your warranty. a little self help may prevent time consuming and inconvenient repairs at this stage, but remember gears are clunky and come in for a lot of abuse, reliable as they are.

Ive got a truimph bonneville t100 2008 exhust pipes tuening blue at the head and golden by the silences is this detremental?

It is 100% normal and caused by the exhaust heat. A pointer though; if you do any work to the bike and had touched the exhaust pipes, clean them thoroughly before running because you will end up with fingerprints on the pipes that will be extremely difficult if not impossible to remove. Safe riding.

The Bike is now twelve months old with 4250 miles on clock At 9 months old with 3500 miles on clock it began to miss gear changes - up and down - mainly third gear to begin with then progressing to 3rd and...

It could be as simple as the selecter arm that turns the drum , this will be visible with the clutch cover off( and maybe the clutch) this selector arm is on the other end of the gear lever shaft

The drum is the internal part that positions the selectors in the gbox, when you say there is no resistance would mean its not turning this drum. so its probably not an internal gear or selector fork problem

My bonnie just stopped...

If it stopped while the oil pressure light was may have damaged your engine. Your best path here would be to take to a dealer and have them check the bike out. Yes, I know this can be costly, but you are risking possible motor damage here, which is BIG bucks. Sorry don't have happier ideas.

Problem getting bike into gear while riding

If the problem only happens when the bike is cold, the oil could be the problem. If the clutch lever has excessive endplay, the clutch needs to be adjusted.

Have a heavy rattle in bonnie 865 motor when hot only 4,300 klm

Pinking is usually a sign of a low octane fuel, altitude or high temps that can sometimes be lessened by retarding the ignition timing a few degrees i.e. the plug sparks when the piston is closer to TDC. This is not always easily possible on modern bikes with the ignition advance/****** controlled by an ignitor box rather than a mechanical points type set-up.

Severe pinking for long periods can & will burn a hole through the piston crown. If a higher grade fuel is unavailable, try finding some sort of octane booster to add to the fuel (off road shop?).
