Hello,

My friend let his Vaquero for 2 hours idling .... by mistake, he went to shopping meanwhile :)

After 2 hours he found his bike running with no issue.

Can it happen some bad things with his engine ? like premature wear, or anything else ?

Wow, 2 hours idling and it was still there??

I don't see that anything would go wrong as long as it didn't run hot or low on oil or similar.

In my area, people don't even leave their car running long enough to go inside a convenience store to buy a cold drink unless they have someone sitting in the car still.

I explained in a wrong way.

He was at home and start the bike, into the garage, just to charge the battery and to see if all is OK, as we have a 3 days ride trip in this weekend.
His intention was to let the bike idling for about 10 minutes, in the garage.

But, short after he started the bike, his wife told him to go for shopping :) :) And, of course, he went for shopping and forgot about the bike idling into the garage ...

I understand that the wife is the BOSS, when she told him something, he forgot everything :)

I hope all is OK. Maybe the fan was running too much ...

If he has model with a catalytic converter, exsessive idling will shorten the life of the catalyst, but doing this once shouldn't be a problem.

I don't know if the bike has a catalytic converter, I know that the bike doesn't have ABS brakes... if this can be a hint ..

But, what is the worst thing that can happen, with the catalytic convertor ? Can the engine be affected in case catalytic convertor is broken, let's say ?

The bike will have no problems... Tell him to take it out for a hard ride, bounce off the rev limiter in the first few gears, clear some carbon out... Good as new.

Smoke out of the exhaust will be a good thing he sees.

First, for a couple instances of extended idling, I wouldn't expect any issues. Peg's suggestion is a good one.

As far as damage to the catalyst goes, too much extended idling will cause the catalyst to plug up, restricting air flow through the system and backing up exhaust gasses in the manifold. That will reduce performance and eventually shut the engine down. But that's a long term issue. Not something caused by occasional idling. As long as these 2 hour idle-fests don't become a habit, I wouldn't worry about it.

Thanks for the explanations. Means we should have no problem in our next weekend trip.

Just thinking : if we will remove completly the catalytic converter, will this affect the engine ? I think there is no connection between the converter and ECU ...

The catalytic converters are integrated into the OEM pipes. They are why you don't hear any popping from the exhaust on a stock 1700. As soon as you put after-market pipes on, there are no cats. You don't strictly need to put a fuel controller on it or better yet have the ECU "Ivanized" for just after-market pipes - but you should do so if the air intake is opened up as well.

Means, if the catalytic converter will get clogged, we have two options :
1. change the stock exhausts, as the catalytic converter is integrated and cannot be removed itself only (or, at least a part of the stock exhausts, where the catalytic is integrated),
2. aftermarket pipes.

Yes... Or option 3: You could simply de-baffle the stock exhausts using hole-saws & extensions, there's plenty of videos online. Measured correctly, (so you don't go too far & through the bend in the pipe) that will make a hole right though baffles and cat, and turn your stock exhausts into open ones.
