My mate has an air cooled mini moto, I was a bit big to ride it at first untill I opened up the clip ons to make them near enough straight and I was comfortable riding it then. I bought a Blata b1 rep thinking I would do the same but my coolant reservoir is stopping me do this atm. I’ve had to drop the bars lower than the reservoir to achieve the desired angle. I’ve seen pics of high clip ons that are nearly straight on b1 reps. How are people achieving this without moving the reservoir?
Theres lil tricks like shimming , trimming or relocating the body , modifying the bars where they touch the tank also modifying the balance bottle bracket...…..
Aslong as you don't physically change the bottle location if you have to add an inch or two of mounting height or move it forwards a lil you'll be alright....
Stand it on a bench sideways to look and see what it takes to get it done...
Theres clip-ons that have offset bar holders too...……I put them on my Black Magic Cag to get the bars in a more forward position.
They can adjust four different ways..Height,angle,protrusion aswell as how far the bars stick out...You seem to have a similar type so pulling the bars outwards more or trimming off the inner length that hits the tank should be the ticket to achieving what you want to do...….
Wider fork clamps will work too...…….Youll need to make new wheel spacers and shim the brake caliper holder......
If you make a nose bracket like I have on my Polini 910 Carena you can definitely do something with the balance bottle..
On my Polini 910 the bottle with cap is in under the fueltank but with a B1 rep that's not possible……..
On my Ziemini Cag I did something a lil unorthodox to raise them over 2" but worked out killer...…..LOL
Good Luck getting the ride comfort problem sorted out...…….
