My new 907 - little fixes before long distance riding

Hi Paso folks,

Finally got one of my long sought bikes, a red 1993 907ie with less than 10k miles. Sadly, here in south Florida it's mostly flat straight roads but I'll make trips up to north Florida here and there to enjoy this bike properly. After the first two short rides I've had to already address some issues (as a Guzzi owner too, I expected this kinda stuff, but we put up with it cause we love our Italian bikes unconditionally, yes?).
So far, I;
1) disconnected the orange wire to the clock since it was draining the battery.
2) removed the overflow tank and had it plastic welded after it immediately sprung the infamous leaks - the welder said it's polyethylene though at first he said it looked like polypropylene. His first welding attempt based on that assumption failed (the bead popped right off). The second weld looks solid as can be, and he welded the entire seam circumference - I'll find out soon if it holds.
3) I ordered a GP spec Regina chain and a 40 tooth steel rear replacing the US spec 38. That 38 feels nice on the open highway but needs way too much clutch slipping in traffic to get rolling. I ordered a 15 tooth front, but I understand there are issues with sprockets that don't exactly match stock specs. I hope the new one is right. If not, my friend has a box of new old stock Ducati front sprockets that we'll try to match up.
4) I ordered LED bulbs for the dash - hope I got the right ones since I couldn't find a ready made kit.
5) I ground a few mil of the side stand bolt to eliminate the silly spring-back feature - the left mirror and panel are at the painter right now thanks to the PO's failure to hold the stand down.
6) I angled down the shifter (no problem) and brake lever (trickier since you gotta pull that rod from the plunger and clamp and twist it to lower the lever, being sure to test afterwards it for any slight brake drag that'll boil the fluid). I did this 'cause I'm ordering lowering pegs. I know, I may have to readjust them for fine tuning when the pegs get here, but I had a few minutes to kill.
Anyway, more to come, I'm sure. Thanks for having me!

You can use a variety of front sprockets by making a spacer to fit on the outside of the sprocket to get correct offset. I cut a 5mm(i think) piece of dural the same shape as the securing ring with large hole in middle and two holes either side for the bolts. I now use SS sprockets with zero outer shoulder. You will need longer allen bolts, clutch spring bolts are perfect.

Thanks, 900streetfighter! Fortunately the new front sprocket I got off ebay was a perfect replacement for stock. And the new 40 tooth replacing the stock USA 38 tooth rear makes the bike feel like a Ducati should; no more slipping the clutch.
The lowered pegs - 30mm down - feel great, though any lower and my sidestand would interfere with the also-lowered shifter (my toe sometimes brushes the sidestand a bit, but it's not a problem). The lowered rear brake lever is at its 'low limit' of adjustment -- any more would require trimming the plunger inside that rubber accordion dust cover. it's just good enough where it is.
Also, the plastic welding on the overflow tank did the trick. So nice not to see dripping coolant.
And the L.E.D. dash lights are a big improvement.
Unfortunately, I have some issues with the turn signals. I guess I'll start a new post for help...
