Today I was riding for the first time new to me '07 550 in supermoto guise. I really like it so far. Engine is freshly rebuild, updates done, dual valve springs, orangeberg mod for weep hole, roller bearings etc. Starts perfect, sounds really good and healthy. My plans are to install two cooling...
I would like to know the relationship between different needle straight diameters and PJ's.
For example to get a certain fuel mix from idle to 1/4 throttle, with DVT needle and 45 PJ you would need a ? PJ with a DVR needle and ? PJ with a DVQ needle.
Any ideas?
Thanks, Roland
