I guess. With the 6th gen cooler only being 1 row more and having to bend both lines I just ebay shopped amd found the rc51 cooler. Helps in the Texas heat and I just use velcro with cardboard to block it off during the winter.

Glad to see people are liking the rc51 oil cooler swap. So many years have passed and with the double o-ring setup, shes never leaked. I've been off the forum for some years now. Ive been so busy that riding got left behind. Ive now got two 5th gens. LoL. Such a good deal I'd be crazy to not have gotten it.

The advantage of turning the fan off is so the stupid thing isn't fighting against the air flow when you're at highway speeds and just keeps the engine from cooling down. Stupid that they didnt tie the fan into the speed sensor. I've had to pull off the highway several times to let the fan finally turn off so the engine could get back to normal temps.

Just checked and Im using the 6th gen airbox. The tops of the throttlebodies are different. There is no mount for the two coils so I drilled holes, used zip ties, and used sealant around the holes. If you use COP's than no worries there. There is also an extra 1/2" port on the left that I plugged with sealant.

From the sounds of this... and please correct me if I'm reading incorrectly between the lines, are you going to be using 6th gen injectors on the 5th gen engine? I've often wondered about this with the 6th gen multi-orificed injectors getting better atomization if a swap is worth it...You need to swap the entire throttle body assembly then. The 6th gen fuel injectors won't fit in the 5th gen fuel rack. Way different size/length.Rangerscott69 has done this. It works fine. You can use the 5th gen ECU. Does the 5th gen air box fit on the 6th gen throttle bodies or do you need to use the 6th gen air box?If Rangerscott69 is listening... how did this mod turn out? Performance, ride-ability, mileage, power... any comments? Worth the swap or just neat to do? ...ooops, sorry for the threadjacking Been fine. Not really worth it to do the swap. I just did it it, just to see if it could be done. I wanna say Im using the 6th gen airbox because there is a difference but Ill have to pop the tank. Havent farted with it in a good while. Waiting on slave cylinder rebuild parts. I do have a problem with warm up idle. From 140f to 170 the idle wants to dip down and stay at 1000rpm. Once it passes 170, she idles normal. I just havent taken the time to checkil it out.

The Denso COP's on any bike should have the same female/male connections so the harness can pretty much come off of any bike with denso COP's.

Ha. I never saw that I was mentioned in this kick ass thread. The COP's ran fine while I had them installed. Just took them off because of vacation trips and just wanted to eliminate any problems. There are others that have been running them longer than I have with no problems.

I could have picked that up. LOL

Bike ran fine when I had the cop's installed. Haven't had them installed some time now because I haven't really been able to enjoy my bike. When I'm on her, it's because I've had to go out of town with her and don't like "testing" things while I'm hundreds of miles away from home. Going on a week long trip and when I get back and if I remember (LOL), I'll put them back in.

Still all is well. No leaks either.

I was thinking the same thing. "Might" be a hotter spark. I know there are dirtbike guys that'll run a coil off a different bike to get a hotter spark. The only way to know for sure is to get both and put your tongue on them and see which one knocks you out longer.
