I've noticed a progressive problem with my Speedmaster, in that the choke and tick-over are a bit erratic. It starts from cold but there's a lot of popping and pinking going on around the choke and carb. Once warm, rather than chug on nicely, again it seems a bit erratic and cuts out now and then. Once running, she seems ok; just the usually growly acceleration and a nice bit of pop on the deceleration.
No way am I going to fix it myself. I just wondered who the best person to take it to would be. I know that there are Triumph specialists in Newcastle and York but if it's only a case of a tune or chcking the mixture, surely there's somewhere local that can sort it?

carbs may need adjusting,.
although my previous (bandit) & Current ZX6 had same problems,. start up without the choke on and it cuts straight out, when the choke is on,. as engine warms the revs fly up, so have to adjust choke down and once it has warmed up it runs fine with choke off.
not sure if this is the same as what your discussing.

I don't think Garry will have the time at present. He has had one of our bikes in for two weeks and not had time to look at it yet. |

Waste Gas analysis on a rolling road (Dyno) will help to diagnose what is happening with the air/fuel mixture throughout the rev. range.
AMR at Bellerby sorted out BOB's Bike, they were the only guys who were prepared to do what was required, none others more locally would.

I know from first hand experience that they can tie down powerful fire spitting evil bikes , and tame them accordingly but the speed-master as described is maybe a step too far ? ( unless they've got new straps ) |

Just topped it up with the exact oil recommended by Triumph (Some Castrol 10W 40 stuff). I may pull the plugs in the morning and have a look at them. |

I may pull the plugs in the morning and have a look at them. This could be the cause , esp if you've put way too much oil in . Too much oil is bad news . Check your level before trying anything else , in my opinion . |

I need a dwarf with a stoop. |

Also, check manufacturers guidelines as to how to check oil.
Some bikes you check with engine warm, some cold.
Eg. Former works BMW R1200RT - when cold it looked like there was no oil in it. No matter how much you added, it still didn't register (as one force to my knowledge found out the hard way). If you checked the handbook, you soon discovered that the check had to be done with the engine warm.
Have you checked the oil correctly John, should it be engine warm or cold? Not sure myself, but always check....

Not sure myself, but always check.... On most engines I have known, the oil needs to be checked whilst the vehicle is on firm level ground with the bike upright and not lent over whilst on the side stand ? Look at your manufacturer's owner's manual and if required by the owner's manual, get somebody else to hold the motorcycle upright while you check the oil level, cold or warm as advised and drain oil slightly if too full to right level if required. Then check and clean the plugs afterwards. Too much oil can cause hydraulic overpressurisation of the crank case and can ruin your engine for good. Oil is a liquid and unlike gasses is not compressible, that is why "brake fluid" is used in brake hydraulic systems. |

On most engines I have known, the oil needs to be checked whilst the vehicle is on firm level ground with the bike upright and not leant over whilst on the side stand ? Look at your manufacturer's owner's manual and if required by the owner's manual, get somebody else to hold the motorcycle upright while you check the oil level, cold or warm as advised and drain oil slightly if too full to right level if requred.

Oil is a liquid and unlike gasses is not compressable, that is why "brake fluid" is used in brake hydraulic systems. From what I've read, it's best done warm, which I did, with help from my brother to stand it upright, as it should be, in my garage, which is fairly level. It's still in a bloody awkward place to get down to in order to check, though! I'll need to enlist someone to hold her upright again in order to check (again) and drop some oil out if necessary. Longing for the days when I just took little Lexi over to Pioneer and they did all of this stuff for me. |

Try this web address( copy & Paste ) for the triumph handbook images.triumphmotorcycles.co.uk/media-library/BC89FF86FC554E9A96862EBF62A748BC.pdf. This what you have to do. Oil Level Inspection Start the engine and run at idle for approximately five minutes. Stop the engine, then wait for at least three minutes for the oil to settle. Note the oil level visible in the sight glass. When correct, oil should be visible in the sight-glass at a point mid-way between the upper (maximum) and lower (minimum) horizontal lines marked on the crankcase. Note: • An accurate indication of the level of oil in the engine is only shown when the engine is at normal operating temperature and the motorcycle is upright (not on the side stand) Geoff |
