problems out of nowhere?

Post by shinerman » Mon Oct 14, 2019 9:04 pm

So the 2009 T sat in the garage for the past 4-5 months with the occasional start - the 100+ Austin temps this summer just don't make riding enjoyable. this weekend i decided to take advantage of the cooler weather and go out for a ride. She had a very hard time starting like it was starved for gas, then rough idle with a much louder exhaust sound. I finally got her warmed up and out for a spin and she it seemed like she was running smooth with some fresh gas. then the idle became very high which i think was an issue with the throttle splitter. I let it set for a day and tightened up the exhaust connections at the cats which i could see were leaking. this did not help and i'm still noticing what seems like a small leak. then i noticed my headers glowing bright red when she was idling in the driveway.

I must say that this has never been an issue and the bike has run smooth since i had it delivered from the previous owner about 6 years ago. carbs have never been touched by me but the plugs are black and sooty. Any direction on where to start would be appreciated!

I'd pull the carbs for examination and cleaning. Voice if experience here, as it concerns similar running issues on a motorcycle that ran poorly after a period of storage.

If you've access to ethanol-free fuel, do consider using it.

Also check compliance fittings for cracks.

I would drain the carbs if it was going to sit for several months. Starting and it warming it up occasionally serves no purpose. As for the louder exhaust, could be a baffle rusted out internally? Both sides loud or just one?

chaos2, the right side is louder - and that's where i found the largest leak. I should know better than let it sit so long without draining the fuel....I'll give the carbs a good cleaning and start there. I also ordered a set of the new style carb branch pipes since I noticed that the stock 3 piece pipes barely stay on at the carb and easily slip off.

Thanks everyone for the responses!

If you have been having problems with the branch pipes slipping off the carbs consider getting a set of "Perch rings" from Raceway. They attach to the carb intake flange and extend it so the pipes have a better grip and can't slip off. :)

I second this.

I recently did the perch rings, new style tubes, and phenolic carb blocks / spacers. Everything is much more secure now.

You might try some gas additive cleaner to your tank and go for a good long run. Probably won't do any good, but then again it can't hurt.

Image Yep.

Modern gas must not be left indefinitely in carburettors. Fallout of hard deposits after evaporation claggs them up.

...with the occasional start...

Check exhausts for rodent nests.

Happy to report that she's back running fine. Carbs got a good cleaning, installed fuel filters, perch rings and new style tubes to the air cleaner. also did an oil change since gas clearly backed up into the crankcase, sealed exhaust leak on the right side pipe, and adjusted the mixture to lean out the carbs a little - plugs look much better now. also added some stabil to the tank.

Thanks for all of the excellent advice!
