Okay I got a motor from ebay, could not find one anywhere else or local. At the time I did not notice it but the ebay motor has this box next to the oil cooler. From the box two sets of tubes or wires go into the engine close the exhaust ports.

What is this box and will it affect the performance of my F3 or screw up emissions?

Is there a major difference between U.S. specs and Jap specs?

 

post pictures, i know there is a difference between uk and us spec, uk having more emissions.

 

Sorry about that. Turns out its not a Jap motor its a Cali motor with extra exhaust. Need to figure out how to delete it.

Thanks

 

extra exhaust? what like an egr valve or something?

get a haynes manual that shows you the difference between specs with a wiring diagram so should allow you to figure out how to delete the extra rubbish.

 

The extra exhaust injects air into the header ports to get clean emissions. So I removed it and I am going to have some plates made to block the two ports. Also the California engines have less aggressive cams. You lose about 8 hp with the cali cams. So I swapped out the cams. Now my cam chain tensioner dose not work so I have to order another one.

 

Get a manual CCT.

 

im with dirt on this subject i'd stick with the oem auto cct, mine lasted in mine for 15k to 20k miles

 

Yes but a manual cct isnt just for 20k miles its for life best thing i ever put on my bike

 

The manual CCT is very simple and easy to install and use. You will rebuild the engine before you have to replace a manual CCT.

 

I just installed the Ape manual CCT. Now I am finishing Iinstalling the engine . Plates to block Cali emissions sow be ready soon.
