#1:  Running on one cylinder - fix Author: lassesand Post Posted: Mon Feb 09, 2004 4:42 am

Here's a useful tip, from the German TR1-site, that helped me getting my TR1 running on both cylinders; posted by peter sadecki on 15 November 2001 at 17:21:29:
I had the same problem, usually after the bike had been parked for a while. There are vent tubes coming from the carbs and running to metal tubes which then run along the frame rearward to the airbox. Test your bike this way: when the engine is running (on one cylinder) unplug the rubber vent tube of the carb feeding the dead cylinder (always the front on my bike) from the metal tube. You will need to jack up the rear of the tank for access. On my bike, this results in immediate perfect operation. The solution is to rod out the metal tube all the way back to the airbox. I have found that a bicycle brake cable about 18" long works best; it's flexible and the right diameter if you leave on the road bike mushroom end. Don't be surprised of you discover cobwebs and dead bugs clogging the vent tube. This worked for me.

I had been wrestling with the problem in 2 months and was near a nervous breakdown so this tip really made my day!!

That is a really good tip!

I'm going to add a rolled up bicycle cable to my tool bag.

Here in Frozen Wisconsin, we have bees that we refer to as Mud Daubbers. They build a nest by packing mud into any small opening, then they crwal in and seal the outside. During my last ride in '03, the rear cylinder quit suddenly as if out of gasoline, even though I was returning from a fill-up. I wasn't able to locate the problem before I put her away for the snowy season. error

The first thing I'll do before I start her this spring is to rod out both atmospheric vent tubes!

Thankyou! :grin:

wow, im so glad i found this post, i think im going to try that because i just picked up a virago500 and it starts on both and with starter fluid it will run on both but normally it will only run on chock on one cylinder, i figure if i can get it on both then i can run a bunch of chemicals to get it farther along, thanks

like lassesand said ,,the carbs vaporlock if they cant breath,,,but be careful you could also shove stuff into it like spidereggs,and mudduaber dirt,even the insects themselves...
thatll clog em up good ,,then u ur stuck with two options,,,,dont ride,, or tear the carbs apart to remove the debris....
