ATC500R "Build Thread"

[JasonB]

Complete seals and gaskets kits showed up. New prox rod and 89.5mm vertex piston, cometic top end rebuild kit, crank bearings, oring chain and swing arm rebuild kit from all balls arrived, and a water pump rebuild kit from hot rods showed up as well.

This is my motor in the container sitting at MRE in Canada. Sent it out week before last and Adam got it last Thursday. It's waiting for a TWIRP port job; ported cases, bored and ported cylinder, and milled head. Everything is going to be glass blasted and ready for a coat if VHT paint. Debating on painting the motor some ridiculous color. My brother Eric has my crank and the ProX rod to rebuild it. Hoping to get all the parts back by mid January and have the bike siting on inverts and a 450r rear end by late February.

Heads up next time. I got a part number for a oem gasket set. Its cheaper then the aftermarket one and comes with a OEM head gasket! Who is Eric having rebuild the crank? Ill be really interested in hearing how you like that guys porting, I called and talked to him for couple hours. Seemed like a good guy and didnt pressure you into sending the motor to him if his porting style wasnt what would benefit you.

[JasonB]

Damn it Honnerlaw! that would have been good to know lol. I ended up going with 90% of what Adam recommended for this build including the Cometic top end rebuild kit. He is cutting/shaving my 88 head to work with the 90-01 head gasket. And Adam is a cool guy, didnt pressure me into sending him my motor or anything above what I was looking for. I figure if the motor is being refreshed why not spend a little more and go overboard. I forget what he said the TWIRP jobs normally see but its a solid increase in power that they find in case and cylinder porting. Why not lol. And Eric is going to be doing the rebuild with Sprock at his farm. cant count how many cranks I have seen Corey press out up there. I will be giving feedback through the process with MRE and posting as many pics as I can. So far Adam has been great to deal with he is real open with communication and calls/texts anytime something pops into my head. Definitely the kind of customer service I am happy to support. Last I heard from him he said my cylinder had been resleaved (previous owner) but done very well, he was measuring out the port timings.

Also I will be looking for another 10" wheel from you around February so I can get both the 310 and 500 on their own wheels. The one i already have is great thanks again

I talked to Corey about doing a couple 500 cranks, he had said he was having trouble getting cranks done true and with the Honda cranks having the tin shells he wasn't willing to do mine.

Seems to me for the 1200 bones mre wants I would have sent him the crank too and let him do the whole thing.

updates:

just spoke with Adam Millar. Cylinder has been bored over and ported. cases have been bored and he's cleaning some other items up in the parts washer now. Theres a few items on the cases that are going to be welded/repaired as well while he has them. He will be sending everything back bare and glass blasted ready for some paint. He is also sending back a set of CNC machined stator and clutch covers, along with a custom reed cage with carbon fiber petals from VForce. He is basically making his own version of the vforce2 reeds for the cr5 motors and has been waterjetting the flanges out and having VForce make petals to his specs that function best with the cr5 motors. kicka$$ stuff. Should have everything wrapped up for me end of next week. SOOOOOOOO then it will be a mad dash to assemble the motor, paint it, and make the bike functional again by March for the Invasion. MUST. WORK. FASTER.

Picked up this 450r 2007 swing arm, carrier, swinger bolt, stock and adjustable dog bones, full brake set up, and extended axle. Grabbed it tonight, been picking Halls all knowing brain about how to install this bad boy the RIGHT WAY! I'm excited, inverts are up next on the list and the hope is to have them made and at my door with some cr125 forks cut down in the next 2 weeks. Motor is supposed to have shipped today, when it shows the plan is to go hang out with Eric and Sprock to assemble.

Thing is gonna be nuts, can't wait to see it done

[JasonB]

lol tell me about it man. My goal was the INVASION, but my budget was either inverts and 450r rear end swap for the 500 to get both my bikes ride-able or just cobble one machine together for the invasion. Trust me I'd rather play in the sand in CALI than the dirt in OK. But the trip to OK is worth 100$ in gas round trip VS 1600$ in gas round trip to Gordons. hard to argue with that. My group will hopefully be eye balling Calli for next March, we need 5 or more people to break the cost down to the $700 per person we spent last Invasion 2013 to make the trip and out back. Money makes the world go 'round!

[JasonB]

Don't worry man I know where you're coming from lol and the 500 will be ripping the bowls at Gordy soon enough with the 310 as back up. If you haven't narrowed down a frame yet talk to John McKane he built a gnarly banshee trike and I can't recall for sure but I think the frame was up for grabs. Such a bad machine!

[JasonB]

My cases were a bit beat up, they welded a handful of spots to repair odds and ends like where jb weld was hiding a hole a chain punched in the case. And some engine mounts were chipped etc.

When I get everything back the plan is to slap it together with all the goodies I have sitting in the shop. Closer and closer. Ordered a set of 2001 cr125 forks and rebuild kit last night, they are headed out to be shortened and rebuilt while the tripples are being machined.

[JasonB]

Ended up needing the exhaust flange machined and the threads in all three holes there needed some love. Also upgraded to an oring exhaust flange. Pretty gangster.






Tasty port work
