Metric Motorcycles and ATV  specializes in Superbikes, Cruisers, singles and ATVs.

I would like to be different and appeal to the cruiser guys as everyone seems to want to do the others.

We also love the new 4 stroke singles for every application, off road, street and quad.

We tune classic Japanese bikes, the ones that a dealer has maybe only seen pictures of - never worked on. We still know what "points" and "carburetors" are!

We also do classic Italian bikes and have  “certified Ducati Mechanics“ on staff.

A long list of machining capabilities including welding.

Street and Race work - including engine and transmission building, fuel injection tuning, Teka SFI Suzuki tuning

Custom tuning using the Factory Pro EC997 for True HP.

I've been taking my y2000 ZX12 1427 to Dynojet shops for 5 years. A total crapshoot on hp/tq. REAL difficult to tell the difference that mods make.

Even worse, I lost 2 motors on the Dynojet dynos due to????
It got so that every sweep I crossed my fingers, prayed to every god I could think of.

Last Nov. I started going to Houston's Metric MC's EC997 Factory Pro dyno. What a difference.
The numbers are very consistent, predictable.
Maybe because the operator/owner (Andy) is religious about getting motor temps "right" before doing a session?
Maybe because the Factory Pro is just a better piece of equipment/system/method???

Best of all, although I can't prove it, the steady load seems MUCH, MUCH easier on the motor.
We are tuning my NA motor for the Texas Mile and during Jan/Feb have done 5 dyno days (3 with different cams, 2 with different injectors). No motor problems.
Holding the motor at 11,500 for 4-5 sec? It seems to love it. I no longer cringe.

Hp difference between DJ250 and Factory Pro? In the range of 15-20% Hard to tell exactly because DJ numbers varied 5-10%.

thumbs up to Marc & Factory Pro!

thumbs up to Andy of Metric!

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
