Finally decided to go for the obvious answer for the front indicators.. drilled the headlamp brackets, so it pretty much copies how Guzzi did it on the original bike. Next, turns out my newly bought throttle cable.. had to get a shorter one for the clip ons.. doesn't fit the Tommaselli throttle, so ordered a kit from Venhill and I'll diy. Got a similar problem with the choke, as the LH handlebar clamp/switch gear is damaged, which also holds the choke lever. The solution is to do away with said lever and cables / splinter and retro fit plunger chokes to the Carb tops. Those are £15 each, which isn't too bad in the scheme of things.
Yesterday the stainless LM silencers arrived from Keihan, went for the earlier LM1/2 style rather than the bulkier LM4/5 design. They look well made and fit ok, except for the mounting brackets not matching up with the Tarrozzi rearsets. Not really a surprise, so that's something else to sort out.
I'd originally wanted to something similar from Armours, but despite Emails and many phone calls last week, they never replied or picked up the phone. So went with the slightly more expensive Keihans, ordered them on Tuesday, arrived today, two days later.
