Tr280I Winter Makeover

That -25 temp made me think back to the original bore / piston damage.

Could the bike have been cold seized at some time?

A cold seize usually occurs when the bike is worked hard (even very briefly) immediately after the bike is started in cold weather. The piston heats up fast and expands before the barrel has time to warm and expand. In some cases the effect is that the inside of the barrel expands inwards unevenly as it warms because it is constrained by the still cool outer barrel.

I have known this to occur even at UK winter temps of about 5 to 6c so I would think it could easily happen at your much colder temperatures.

New plastics and stickers together.Used plastic bolts for the rear fender (trimmed the bolts with sidecutters).The airbox cover was unavailable in Canada,so it came from Zonetrial in Belgium in 5 days!

Piston is in (the right way round).New cylinder head o-rings were not available so i reused the old ones.Lapped the head on a heavy piece of plate glass.

The footpeg pivot screws and shafts were assembled with waaaaay too much loctite at the factory.I had to wire wheel the screws and chase the pivots with a tap.

If the fuel system were a little smaller,maybe the gas tank would hold more than 3 liters.

Lockwired the fuel line connectors.I'm NOT pulling the motor to reconnect a goofy fitting.

All done.That was a project! It runs great.I can tell there is a new piston and cylinder in there for sure.The extra base gasket makes a little bit of a difference in the force needed to kick it thru.Just what i wanted. :)

Powdercoat by my friend JohnnyP is second to none.

SplatShop frameguards.I didn't do this much work just to watch my boots wreck the cool powdercoat.
I also put a couple of chunks of 3M paint protection film over the side plastics.
Trials competitions here i come.
