BTW, here's the same bike back in 1985, with my wife and I leaving the church after our wedding!  Still riding the same bike, AND the same woman!

Tonights job just so happens to be a 85-86 atc250r pipe. I’ve had the 3 wheel itch since i picked up a 86 atc250sx a few months ago

This thing is gonna rip. 

I sure hope so.

Made a few changes while getting around to final assembly. Switched to an old school mesh number plate. Added a set of tie down brackets since I can't use Flexx bars as a mounting point anymore.

Where did you get the tie down brackets?

Bought them off eBay.  There aren't any posted right now but here is a link to the guys store.  You might have to send him a message.

A few new upgrades.  With what OE plastics & seats are going for I decided to put mine on mothballs. Picked up a spare seat base & foam about a year ago. Bought a Fourwerx seat cover to try out. Used set of Maiers off CL for $50. Gonna figure out a way to secure the seat with a lock and the new rear latch system. Also, my Selvey pipe sat a little too close to the rear brake reservoir so upgraded to a Nelson aluminum.

New aluminum radiators with silicone hoses are on. Far from "bolt-on" but they fit.

Here is some progress from the last few days.

Decided to run a PJ so freshly rebuilt with 150 main & 50 slow to start the tuning. Mounted the killswitch. Fresh Sunstar steel sprockets (13/39) and a x-ring DID chain. Hit the pipe with some scotchbrite & WD40. Painted the rear hubs back to gold.

Nice work.

Great weekend in Glamis with @wapawekka.  Took the new build out for a shakedown and learned a lot. Bike runs way too rich due to lack of airflow. Air box lid has to go and possibly the 34mm PJ. Gonna look for a 36mm or 38mm PJ. To run with the stock box (possibly aluminum replacement). Bike runs ready strong once it leans out.

New radiator hoses rub a little on the gas tank. The kickstarter hangs up on the new pegs and releases suddenly into your shin if you aren't careful. I like the Fourwerx seat but need to learn to shift my weight differently instead of just sliding on the vinyl seat.

Is that the infamous plane crash site in the background?
