Busted Knuckles: The Vintage Scrambler Restoration Project by Trinity Customs Werks

For this week we have something special for our bike restoration, and vintage bike enthusiasts
out there.  This is truly a busted knuckles build as the talented team from Trinity Customs
brought this vintage bike back to life after spotting the diamond in the rough in the stock yards
of Singapore.  The project was headed by Edwin Jinco. It was one of the most challenging builds 
for his team since the bike has not been used for 3 decades and it was literally in pieces when they
found it

The Team went all out to face the daunting challenge of rebuilding the bike without period 
correct parts.  They had to be creative and custom build some of the parts for this project.
One of the toughest challenges faced by the team was qualifying if all the engine parts in the box
that came with it are still usable or within tolerance. They had to do some research to get the 
actual numbers and specifications. Only two parts needed cross-referencing using an aftermarket
 brand since the OEM brands are no longer available. 

For the engine the team wanted it to exceed all performance numbers. They did this by lightening the
flywheel, balancing the crankshaft to reduce the vibration and rocking motion which boxer engines
are notoriously known for. They also did some porting and polishing in the intake and the exhaust to
give it a bit of kick. Another challenge faced by the team was the synchronizing of the carburetors
and to get the jetting and timing right.
