radiator upgrade

Would there be any interest in a replacement large capacity radiator, similar to the one supplied by a certain European accessory company? I have an estimate from a company (far east I'm afraid but it will keep the costs down) of us$200 plus shipping.

Minimum order is 5 but if we get a few more there is always the opportunity to haggle a discount.

Is there a need? Are folks' Xs running hot? How about adding a shroud to the fan to make it more efficient, or adding a second fan?

My fan comes on after only a few seconds at a traffic light or slow moving traffic. Off-road it seems to be on most of the time. Probably not helped by the fact that the central part gets obstructed by mud despite me closing off the slots in the fender and extending the rear section. I spent a few hours trying to clean it out last year but it still didn't flow as well as the edges.

That's an interesting way to fill the gap left when you swap fenders. Hmmm

Might increase condensation in the oil on short journey though as it would not get hot enough to evaporate moisture. This is already present in mine over the winter months.

When I had my rad out for a repair, I noticed the stock thermostat to be very restrictive, and had hoped to remove it. One false move would render my bike non-op. At ~$200 this would be a great replacement for the stocker, which I could then modify without fear of failure.

Keep me in the loop please

Maybe if it was plug and play of just a little install work.

If it works out install will go along the lines of:
remove side panels and radiator cover.
remove radiator.
swap the fan over
install radiator and fill it
put the panels back on
I'll take the 1st one and check it fits.

The plan is a full width rad with an overflow bottle mounted behind. Unlike the stock rad which is double pass - water flows left to right and back to left, then goes into a pipe passing less than an inch from the header as it comes out of the engine so it can go into the right side of the cylinder head. - my template is a single pass rad - water goes left to right and straight into the engine.

The single / double pass bit makes little difference. Assuming an equal rad volume it would stay in the rad the same time. The rad I am planning has a larger volume so the water stays in it longer and is cooled more. It has a larger frontal area and is slightly deeper front to back. I doubt that passing cooled water right next to the header helps the cooling much either. The design has already been developed and tested. I'm just aiming for a better price.

I can't justify 600 for a new rad, 200 after shipping and import taxes is possible

Interested. Will have to see what the prototype looks like.

Will the oem fan and tt radiator guard be compatible with this radiator?

If that solution will be plug and play (no changes in mounting points, cooling hoses, use of standard fan) and price will be around declared 200$ I might be interested.
My original radiator has most of the fins bended and that caused that air flow is highly restricted.

I took my tt guard off because I think it is too restrictive to airflow. Having said that, I still think it runs too hot. Maybe this radiator will allow me to put the guard back on.....

Fan will be compatible. Since the dimensions will be the same as the TT radiator there is no reason for the guard not to fit.

With the standard guard you would want to take a dremel to open a slot on the left of the guard. There is a slot moulded into the plastic but it is closed off. Have a look if you're not sure, you'll understand what I mean.

Is there a downside for opening up that slot? Why is it closed off ?

Because the stock rad is not full width; it has the header bottle at the left end. The rad I am planning is full width, with the header mounted behind the rad. This gives the rad a larger volume and frontal area, improving cooling.
