Hi,

I'm a new owner of 2000 Triumph Thunderbird Sport, but it has an idling issue and I feel engine is also little boggy, I need to know if there are any good Triumph knowing Mechanic , who can diagnose what's really wrong and fix it , as I can surely tell engine is not running at it's full power, something is amiss . got real good mechanic to fix carbs but he is better at Japanese makes than any other specially not triumph , also he worked on intake valves and i believe that has also got why engine is not running good. so I am looking to find someone who knows triumph specially older like mine, If anyone here knows someone who can help fix it, I would be grateful.

I live Mississauga, ON , basically greater Toronto area, so anywhere around southern Ontario is fine.

Thanks.

Hello and welcome to the Classic Triples Forum. You don't explicitly say where you're from but as a wild guess I'd say Canada?

You're lucky that I saw your post as it's in entirely the wrong section (if a mod could move this to the main area that would be much appreciated), as this area is for known tricks and tips, as stated in large friendly letters at the top of the page -

"Maintenance Tips and Tricks for the T3 Classics Maintenance tips, tricks, performance suggestions and proven setups for the Hinckley Classic Triples. DO NOT POST YOUR QUESTIONS HERE!!"


..but enough of the friendly sarcasm for today :).

The carbs on your model are made by a major Japanese carb manufacturer called Keihin, these carbs are featured on many many brands of Japanese and non-Japanese bikes so shouldn't be anything new to any bike mechanic who has a proven track record with carburetors.

From your description of the problem I'd first be looking at the airbox and it's associated pipes. If the front airbox has any slight leak at all it will cause running problems. This issue has been posted & discussed to death here and there are many easily found threads dealing with these issues. There's a really nice feature we have on here called search. It's hidden in full view at the top-rightish side of each page. No honestly, I wasn't being sarcastic there, well yeah OK I was, but it took me several months to notice the bloody thing myself!

These bikes are really quite easy to work on yourself, but if you don't want to then it might help you in the long run if you buy yourself a repair manual anyway (they're only around 20 to 30 euro-dollar-pounds) and offer to loan it to any mechanic you might want to employ. That might save you a lot of money in the long run.

As a first step I'd simply check the front airbox for cracks/damage/holes, then make sure that two hoses are properly connected to it and are also not damaged in any way. The hose connected to the front of the airbox should be connected to the crankcase vent on the left side of the engine casing, there's also a second hose that comes off the very bottom of the front airbox that simply comes out at the rear suspension linkage underneath the bike. This hose should have a plastic bung in the end of it and should be blocked. It's an "excessive oil" drain tube, and if the end is open it will allow dirt/sand/bugs to be sucked directly into the carb bodies = bad.

Good luck :).
