By popular demand I thought I would start a new thread on the build of my 2001 Guzzi California. I have had it a few months but only really started things in earnest last week... I had been doing some jobs in the background though before I got it on the hoist. here is how it arrived. how it looked naked! I bought some FCRs to put on it, and decided I may used some bell mouths.. so I set about making some... here is a video of how I made them
One thing I hated about the bike was the side stand… Just how agricultural is that bracket! I know its a great functional design, but its SO ugly! so out come the angle grinder and it is no more! In the loft (or as my wife calls it the spares department!!) i had a side stand off a 1994 Honda CBR 600… it bolted straight on! Just need to adjust the angle a little when the ride height has been set. a job for much later on...
Up on the hoist for the first time… I have temporarily used a build stand that I have used for Ducati’s, but I will have to make a specific one as this one will impede making the exhaust fit on the bike. First job has been to make some inlet manifolds to fit the carbs… I wanted them angled upwards and inwards, and that took some working out to get the compound angle right! it ended up as 68.5 degrees. As the carb diameter is larger than the head inlet, I needed to use a tapered tube… To do this I turned up a tapered mandrel, and after annealing the alloy tube, I pressed it in with the vice, which expanded the tube by the required few mm. I then turned a grove to accept the lip inside the carb mounting blocks. the next bit was actually quite difficult… I needed to make the hole on the flange a nice fit on the tube, but at an angle. I deliberately cut the 10mm plate quite large so I could get it mounted on the milling machine at the exact angle. I then bored the hole with an indexable boring head. If that milling machine looks old, it is! I did some work on it a few months ago and found a date… 1929! Next job was to TIG weld the flanges on, drill the holes, and finally cut to shape. here is a video of how I made them
yesterdays job was to mock up the exhaust... I had ordered some 2" mandrel bends and straight pipe as I wanted that chunky look, and for the pipe to fit straight into the silencer with no reducer. From a performance aspect, the large headers are probably not I deal... but I wont miss a few BHP! I also wanted that angled swept back look (old School!!) The bends are 135, 45 and 30 degrees. It should all polish nicely as its stainless steel. This bike will have more forward mounted foot rests, hence I could kick up the silencers earlier... I find making exhaust systems quite therapeutic, although sometimes I could do with a third hand. My wife used to help, but since I burned the back of her hand with the hot end of the filler rod, all help has been withdrawn
yea... She certainly never forgot when I was welding up an Arial hole in a car wing... I gave her the disc of metal, and a punch to hold the metal disc in place under the wing... she put the disk in place and I said "ready".... unfortunately she used her finger, not the the punch I did try a different approach...
Next on the list is the new foot controls… I sat on the bike and decided where I wanted the foot pegs to be. This bike wont have rear-sets, I want to to be comfortable to ride! I then measured how long from the peg the brake and gear lever needed to be and set about designing some controls. It would have been easier to have had them water jet cut, but that’s a 3 hour round trip for me, and usually quite a wait, so I decided to mill them out instead. What has made a BIG difference to me is the acquisition of a band saw… Its great for cutting stuff like this out! I was so lucky to acquire it… my mate was throwing it out! I made a couple of spigots to mount them on the frame which I will weld on. I have used a couple of Oilite bushes on the holes rather than run the alloy directly on the steel. the first spigot I made I realised I had counter bored it a bit too far and it would have been too weak… a case of measure twice cut once! I then bent them in the vice to get the correct crank angle to clear the exhaust.
she said words i didn't even know she knew!!! The finished results, apart from a good polish... As I am going to use a Ducati rear calliper, I have also used a Ducati Master cylinder, and also used the same leverage ratio for the pedal... here is a short video
As I am taking off the linked brakes I needed to use a different rear caliper. I toyed around with making the rear caliper floating and using a torque arm… but in the end decided to use a neater, smaller bracket instead. It also meant that I could mount the speed sensor for the speedo as I am using a combined speedo / tacho.
The tank I am using is off a V7… It was cheap to buy because it had a couple of big dents, which I have managed to get out. To do this I had to cut a couple of holes in the bottom to give access with a 20mm bar with a dome on the end, which I then used to knock most of the dent out, just needing a skim of filler. I then welded some plates on the holes and leak tested them with dye penetrant. I use this a lot, its great for checking for holes and cracks, they show up immediately. fortunately all was good in this case. I prefer doing it this way to filling it with petrol as if you do have a leak its a pain to clean it out again. I have taken to using the dye penetrant on frames before I have them blasted… its surprising how many have cracks! especially Ducati! A while ago my mate welded an RGV 250 engine mounting on the alloy frame. When he had welded it, he used some dye penetrant around the joints on the frame to check for cracks… There were quite a few! he welded them up and re-checked. Here is a gearbox I recently welded that still had a leak after someone had already welded it, you could not see it with the naked eye, but its easily visible with the dye…
With the new master cylinder mounted I looked at a way of mounting a reservoir. I could have used one of the small plastic ones, but instead decided to make one. I am pleased with the way it came out! here is a short video of how I made it! Last update for a while... I have to go on holiday apparently!
Back from holiday where I unfortunaly got a dose of the virus! Not too bad though, I have had worse colds… But for a few day I have kept out the garage, and did some computer time instead and constructed the wiring diagram… I like to keep it simple, and wire from scratch, so many builds are spoiled by patching up the old loom. I am using an ignitech for the ECU, and its interesting that the the unit uses the cam sensor for one cylinder, and the crank sensor for the other. I like that idea!
