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.

Yamaha FIAT Packard Bell MotoGP Inspired Sniper Classic

For this WEEK we are featuring a Yamaha FIAT Packard Bell MotoGP inspired Sniper 135 classic.
The bike is owned by Ramil Tapiru a Supervisor in Motoworld Archbisop Reyes branch Cebu. The
concept of the bike was inspired by 2008 Yamaha Race bike piloted by Valentino Rossi enroute to a
MotoGP championship title. It was also on that the same year that Taiwanese computer manufacturer
Acer acquired Packard Bell and announced that they will be supporting the Yamaha Racing
Team.

Going into the bike it sports a wide array of Bikers and Racing Boy Parts. Ramil wanted only to
 use the best parts for the bike which should be both functional and at the same time enhance the
look of the bike. He utilized Bikers Brake levers, Bar Ends and Axle guards.  He also utilized Bikers
front brake caliper protectors and rear master cylinder protectors.  To improve the handling he used
Racing Boy Fork stabilizer.

To improve the performance he used K&N filters paired with Hi-Speed muffler. The bike uses
Racing Boy Lever Guard, Chain Tensioner, Oil filter cover and side stand. The bike sports a fender
eliminator to achieve that clean race bike look and it also uses a Sniper MX rear disk brake assembly
which was specially modified by the team to integrate seamlessly with the bike. It also sports a
Noiwatdan replica custom made seat.

The bike was a product of the collaboration of the different individuals behind it namely William
Manaba of William Workz who was incharge of the body graphics. Jr Francia the chief mechanic and
CP Murillo of CPM Performance for the parts machining and fabrication. Joshua Clemente of JPC's
Motorcycle Parts and Accesories who helped them procure the parts. All in all the bike took 5 months
to build as some of the parts had to be shipped from Malaysia and Thailand.













Thai Style Yamaha Vega Force Dragster

For this week we are going old school back in the day when 1.2x17 rims ruled the streets and the
Thai style took our country by storm during the late 90's to the early 2000's. This bike is a tribute to
the Thai style aficionados who are crazy and passionate about drag racing and drag racing inspired
motorcycles.

The bike is a Yamaha Vega Force 115 owned by William A. Manaba who is a sales staff of
Motorworld Archbishop branch Cebu. "My inspiration for this project bike is a Thai style
drag racing bike with a fusion of American motorcycle drag racing elements by adapting custom
airbrushed racing flag and flames plus a wheelie bar at the back for a stable start during the
race." William reiterated during an interview.

The bike is the end product of the collaboration of several individuals headed by CP Murillo of CPM
Performance and Jr Francia the chief mechanic who focused on the machining, lightening and
fabrication aspect of the project. Joshua Clemente took charge for the procurement/logistics of the
parts and accessories. William was behind the decals and stickers and Franco "Cocoi" Harbay Jagape
for the custom airbrush.
