20 Most Recent 2012 Triumph Bonneville T100 Questions & Answers


Hi, Will your bike starts great when cold but once it reaches operating temperature and the engine is shut off for a few minutes then you try to restart it and it will turn over but will not fire or it doesn't do anything, the usual suspects are:
1. When electronics get hot they build up resistance then stop working. It might be an ignition coil, stator, CDI unit etc. First, you must find out if the spark dies out. When the bike won't start, pull a plug wire off, stick a new spark plug in the end and ground the threads on bare metal while someone cranks the engine over. You should see a nice big blue spark between the spark plug gap. Incorrect spark plug gap will cause or contribute to a no start when hot issue.
2. Fuel Tuners have been known to cause this type of problem, disconnect it and see if resolves the issue.
3. Any engine management sensor could be faulty especially the ones that monitor the temperature.
4. Gas cap not venting properly, improperly routed fuel lines they must always go down from the gas tank to the carburetor never in any kind of a loop this will cause a vapor lock. Clogged, bent, kinked, pinched or restricted carburetor vent lines will do the same.
5. Overhead camshaft valves adjusted too tight when cold, this will cause loss of compression when hot, except for pushrod engines they usually get looser when hot.

Hi, Anonymous the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee of $15 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available and some were never printed in English. The Indian and Philippine markets are usually in E-book format only, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download.

Hi, Jacko_69 if some or all of your instrument cluster goes dark/blank immediately upon startup or a few minutes later riding down the road the usual suspects are:
1. Blown instrument fuse.
2. A bad ground in the instrument circuit.
3. Faulty wiring before or after the fuse.
4. Faulty wiring or connector between the fuse and the instrument cluster.
