I want to say 2-3 weeks But they had a Holiday in there when I ordered mine. They are good Quality for the price. I still need to get it mounted properly I missed the two lower tabs when I told them how I wanted it. SO just be specific, yours should be simple.
Originally I needed something for a Woods mini Quad a rider of mine was running and I didn't want to spend 200 on the thin OE radiator it came with and also didn't want a cob in a Huge YFZ either, So I drew up the Apex radiator and specked beefier mounts and bosses to mount a Screen on the front. With it being the first one they had done and for a production machine they could market to, they hooked me up. I was very pleased with it never had a radiator issue again and the machine ran cooler to boot.

Awesome, I read in your TRX150R post that you shortened the 450R size 38mm.....which would work perfectly for this application......If the 250R rad is too wide I may go that route of a custom rad.

It's narrowing down to possibly a Custom Rad or a Custom PIPE.....If the 250R rad works.....the pipe will too!!!

I need the brackets to hold the front fenders together to know for sure.....hopefully obtaining them soon!

Anyway you can take the 450R rad to a radiator shop and have it modified? I think there is still an old school rad shop at Taunton/Simcoe St N in Oshawa right behind the McDonalds there.. Not sure if that rad can be taken apart and maybe made a bit shorter so it would clear the pipe? Not sure what that would do for overheating though making the rad smaller...

I was wondering that too...(I know exactly where you mean....they do gas tanks too!).....but I think it's the CORE they would swap out.....so they would cut the Upper and Lower TANK from the rad and weld in a shorter CORE.....might be cheaper to by a custom rad......I'm gonna try the 250R rad....I just have to fabricate the support brackets.....STAY TUNED

Made some more progress....Got the Motor Mounts all welded up.....gonna swap in the real motor and attach the exhaust and start on the Radiator support brackets.

Hit another Snag....I guess running the Rear Shock the way Honda had intended is not an Option....It hits the Carb.....So I think turning it 180 degrees is OK ?[ATTACH=CONFIG]7351[/ATTACH][ATTACH=CONFIG]7352[/ATTACH][ATTACH=CONFIG]7353[/ATTACH][ATTACH=CONFIG]7354[/ATTACH]

Mounted the Pipe.....made a hanger and need to fab one at the front and the rear. Looks like I have enough clearance for the Plastics....won't know for sure till I get the Lower rear fender supports. But if not I'll fab ones that will keep the plastic off the pipe and use some insulated heat shield.

Placed the Rad where it should be.....so I can open the CAP.....but the Lower Outlet hits the pipe.....So I think I'll close that one off and weld an elbow to the underside as there is plenty of clearance for that.....then just to Fabricate the Mounts for the Rad.....Got a couple of good Ideas.... The bottom of the Rad is 2-5/8" higher than the stock location

Anyone know what goes in this hole in the side of the fender ? Or What these tabs on the frame are for ? Thanks

Well I got a chance for some Garage Time......so I thought I would kick it 250R style for the Rad supports. I just have the top mounts held on by screws.....till I take the frame to work and get everything welded up. Here's a few pics of what I ended up with.

Looks good. An Afco rad would fix the hose routing problem, wouldn't it?
