Hello Everyone,

Last week our Connecticut morning was 32 degrees (F) and I couldn't keep my 2003 T100 sweetheart running from cold start.

Fuel on, full choke, the little miss would turn over fine and catch, but would not stay running. It didn't appear to be able to get to high idle where it would keep running.

I also held the throttle open just a little during turnover/start
but again no go.

Finally, six or seven attempts it started and ran for about 5 seconds, then stall. The next start attempt it started.

Same thing next morning. Do I need accept this as my cold blooded Brit Babe, or does someone have words of wisdom for me?

I would appreciate any help.

Best regards,

Barry

Barry,

Try keeping your hands off the throttle and let the bike do its thing. Also before you try and start it let the carb warmers work their miracles. Just leave the key on for a few extra seconds before you try and start the bike.

I haven't had any problems starting mine yet, but I usually don't get a chance to ride until its a little warmer out.

Capt Don - think you're right ... all our Bonnies for the most part are a PITA to start when the weather turns cold. When I say cold, I mean Ohio, Michigan-type cold .... not 50 degree cold. It isn't the fact that they're carbureted instead of fuel injected, it's just the fact that' they're Bonnies. Mine does start better now that I've rejetted, but my W650 (also running Keihin carbs with no mods) starts on the first turn or two, regardless of whether it's 20 degrees or 85F. Likewise, the old BMW R100 GS has never failed to start in 16 riding seasons and 100k miles, but she bitches a little. So, I can't blame it on carbs.

Also neither the W or the GS have 'carb heaters', so I take that out of the equation, too.

Must be something specific to the way Triumph spec'd the carbs they buy from Keihin .... maybe the way they spec'd the starting circuit ....... maybe valve timing .... who knows but Triumph?

Before I understood how hard these bike could be to start in the cold, I decided not to buy a beautiful Goodwood Green and Gold 2003 T100 with only 960 miles on the speedo, because, guess what, it was less than 40 degrees F, and we couldn't start the bike. It cranked, popped a few times, the typical drill, but wouldn't start. BTW - the owner couldn't get it to start, either.

G'day,

Last winter I rode my T100 even down to 22deg C with no problems. This last weekend I ran on Saturday and Sunday morning at sunrise, 30deg C and frost on the bike and it started and ran no problems.

The trick is to turn the ignition on, leave it for 30 seconds or so, full choke, do NOT touch the throttle, then start your engine. I then let it idle for 15 to 30 seconds before riding off. I can push the choke in after about 1/4 to 1/2 mile depending on how cold it is.

On really cold mornings it may take 2 or 3 times before it fully catches but that is all. Do NOT touch the throttle before it is running.

The carb heaters definitely help warm it a little to make starting easier.

That's the way I do it and it always works for me, even in winter in tropical Medina Ohio. Keeping your hand off the throttle is indeed the trick. Clean plugs and balanced carbs are also important to help it to start.

if your pilot jets are adjusted factory lean, you can help your situation by going to about 3.5 turns out.
Mine sometimes stumbles and stalls the very first time on a cold day, but so far always catches on the 2nd

Last week when I was going to put the bike into storage, it was around -8C (20F?) , and I had a hard time getting the Bonnie fired up. Had to connect jumper cables from my car to get enough juice- but stilll no start. Then took off the side cover and put a glove into the airbox opening to restrict air flow, and that helped.

And right outside the storage building the front wheel slipped on the snow covered ice, so down I went. Broke the outer part of the gear lever, and hit the right peg with my leg, but other than that (and a hurt ego), no other damage.
