There's a member here that had his side covers coated a bronze type of coating that looked like the mid-late 80's XR600 engine covers. Can't remember who it was though. Someone from Texas?

wattner - great build, love your work.

It's funny but us Honda nuts obviously love Hondas but are still pissed at them for abandoning ship in the mid 90s. What they could have done is build a EFI bike back in the mid 90s and set up an ongoing XR hegemony.

As you are probably aware I attacked my XR with a similar motive - build what Honda should have built.

Mine would be down on power relative to yours and it's now about 4-5 years old. I also dont have Ohlins which are very cool.

VF700 stator?

Hey Wattner, where are you getting your stator from? Electrosport?

I have an original Honda VF700 stator but I'm considering rewinding it... but if I could get a spiffy new one it sure could save me some time.

Oh yeah, I'd go with the Jagg cooler with the Jagg oil thermostat over the xr400 cooler and skip the fins. Summitracing and pegasusautoracing also have similar thermostats. If I can squeeze one into my Vanpelt setup I will.

Looking forward to seeing how your bike comes out!!

I have one of Mark's coolers.... I may end up running it. I just am adding the nuts to the frame before powder coating, and then I can try them all out.

I have had many high compression XR's with big fins, and have never had a problem with overheating in the least. I am thinking that the fins and XR 400 cooler would be about right... The cooler from Mark looks way way cool

Now all options are on the table!

What you are worried about is the oil not coming up to temperature.........as well as it getting too hot ....right

Well this bypass turns off the flow of oil to the cooler when it`s cold........back on when it`s hot....just like the thermostat in a cars cooling system...this valve also cannot restrict oil in any way if it fails,it is completely failsafe........

This gives you the benifits of having a cooler without the downside of oil not coming up too temperature to burn off moisture and also not letting the engine heat up quickly.........

here it is at work.........




Marks cooler has more cooling capacity than the xr400 cooler.and gets more airflow.....so if you are running in a hot climate.tight low speed trails.or flyin down the slab.loaded up for the weekend campin and with a 105-106mm slug in the cylinder......you are going to need all the help you can get...

SWEET ride!!!! I remember the build, or pictures anyway! I enjoy the build almost as much as the ride (not QUITE though...) Once the build is done, it is just really nice to ride the bike that you built, especially if there are modifications that suit your personal taste. There really isn't anything that I am doing that does not have purpose, or I feel should have been done by Honda

I Ordered a new one from a dealer on Saturday, but received a message that the email bounced back, so I went on Ebay and found one in great shape from a reputable seller for $45.00 shipped, then this evening I got an email that the original had shipped... Now I have 2. I did not go the electrosport route due to comments from inmates pertaining to quality.... OEM has it's place!

We were informed they are sold out and on back order... I have an FCR41 on another bike. Any reason one is better than the other? I have heard different things, but the Mikuni seems easier to dial in. CW will handle those duties for me this time! He did originally want the FCR, but XR's only had the Mikuni and told me they have had plenty of problems with the FCR, with no returns.. If I had a problem with the Mikuni, they would refund, but stated they never get any back

I am not married to the Mikuni, if there is a better way to go (FCR), I'm in

My buddy who is a retired professional race tuner, etc. a real expert in ALL things motorcycle, says the Miks are much easier to tune and greatly prefers their products over the Keihins.

Also, if you haven't painted the frame yet, did you reinforce the point where the sub-frame and frame are welded together at the lower end; if not I would strongly suggest doing so. Honda put some really thin gussets in there, but on mine with mild off road duty showed signs of stress with the paint peeling/flaking off that indicate the frame sub-frame interface is moving under loads.

Anyway, love the build. MORE PICTURES, MORE BIKE PORN!!!!
