I have a set of 2006 CRF250 forks that I have revalved for offroad. I want to transplant them onto my 2007 EC300 to replace the 45mm Marzocchis.

In reading through the various conversion threads I am confused about the best triple clamp option.

Option 1. Bore out the standard 45mm Marzocchi gasser lower clamp from 57mm to 58.5mm. Two Possible Downsides: This might not correct for any possible change in trail caused by differences between the Showa and Zoke forks. Boring out the lower clamp might reduce the strength of the camp too much.

Option 2. Use Honda CRF triple clamps.
Downsides:
1. The posts I have read indicate that the Honda steering stem is too short.
Is this true?
2. Again the possible trail difference due to fork lug offsets and clamp offsets

Option 3. Use Yamaha YZF triple clamps and correct steering stem bearings
Downsides:
1. A shim may be required for the lower clamp
2. Again the possible trail difference due to fork lug offsets and clamp offsets

Any guidance is much appreciated. Thanks, Steve
