The new Bonnies are great, in all their diversity. I'm new here and I wanted to post some pics of my bike that are more heavily pixilated than that allowed in the photo albums. They may be slow loading.
This is the parts mule for the first Wiseco 904 engine, and the first 1100 (1089) Wiseco/BP engine.

This bike is always in a state of transition.

Lee, that's a gorgeous bike! Is the tach original? Did you polish the triple trees?

Thx.
That's an AutoMeter tach that goes to 10K RPM. I blew the stock tach up after repeatedly smacking the limit. My rev limit has been changed to 8900 rpm.
The triple trees came polished. They are A&A Racing trees with adjustable offset (from 0-7 degrees).

[edited]: Triple Trees offset adjustment
The A&A Racing trees come as a kit from www.bonnevilleperformance.com and include spacers due to the trees being 1/4 inch wider than stock. This offers greater stability, and the offset is set at +3 degrees, which offers a significant improvement in turn-in, yet the wheelbase is longer so stability at high speed is not compromised. I did not test any other configurations, just stock and +3 degrees. I removed my steering damper as a result - it is no longer needed for high speed sweepers.
The offset is adjustable by replacing the eccentric fitting at the steering stem, on both top and bottom trees. Look closely at the pics at the steering stem. You can see the eccentric toward the front of the fitting (oval rather than round). These trees are used in the US for flat track racing.

thanks lee,
just to get this straight,is the angle plus 3 degrees.....or are the eccentrics pushing the forks forward 3mm at the top and bottom of the stem, which would keep the same angle...but would alter the trail.
cheers.

The latter, the trail is lessened and the wheelbase is longer, but the rake remains 29 degrees. This gives a somewhat quicker turn-in (due to less trail), yet maintains stability due to the increase in wheelbase.
Lee
Edit: The increase in the offset is in degrees and not mm, so the net change to trail is greater than 3 mm.

Yes, on the Bonnie. I just returned from the Mid-Ohio Vintage Bike days where Triumph had a great display of old Bonnies. I posted some pics on my forum.
