Guys,

I did a search on the forum to read about removing the "black wart" evaporative cannister from the bike. Nothing came up on removing one from the 2010 F4 model and was wondering if anyone has done it yet...was it hard...and if any special knowledge/tools/fittings were required?

The search engine showed that TPO had produced an emissions removal kit but the general consensus was that it was not a good design...plus, it was for the earlier F4's.

So...anyone have thoughts on this? Is it worth the effort?

Thanks!

The Tom

Have not even looked at the new F4 design. Should be relatively simple and similar to the older bikes.

The TPO kit is a [email protected]#king joke. Don't get ripped off.

Look at the threads....you should be able to figure it out. Basically, the tank cap vents into a charcoal canister which has an inlet from atmosphere (in) and an outlet to the intake tracts. Modern systems (high tech Jap bikes and cars) have a purge valve that opens to clear the collected fumes in the canister only under certain high load conditions.

To remove the system you will need to plug the outlets to the intakes, and vent the cap to open air.

Depending on the location of the can (in the tank??? I don't know) you may need to plug the old atmospheric vent inlet.

If the new F4 has an ECU controlled purge valve then that will need to stay in place to prevent any fault codes, but it need not be connected to anything.

Just remember...tampering with an emissions device may be a violation of the law and punishable by big fines!!! ($40K per infraction in the USA)......


Oh...and the only benefit you will derive is weight loss and maybe fuel tank volume increase. You will not notice any performance gains.

Of course, you will also be contributing (in your own small part) to global warming and smog.....

Thanks! This winter when the bike is on the lift and I have a lot of time...I will carefully look into the hose routing to see what can be done.
