Guzzi 1100 Custom build

I thought I would update... I have been putting a fair few miles on the Guzzi... It runs really well and pulls like a train! the ride is a little hard and I may well change the rear shocks though...

However, not everything on a build like this goes to plan… I have been doing a fair few long and fast runs and after one very spirited run I noticed oil coming out the breather… looks like the one I made didn’t work. I set about a completer re-design, and made one out of alloy sheet. Here is the result. I have given it a good thrashing and all is now well!

Here is the finished Guzzi.

I did spend some time tweaking the ignition, but I have to say that it was pretty close with the advance curve it came with it from Ignitech. It took a couple of days to sort the jetting out on the carbs, but what’s nice is they are easy to get at to change jets, and these carbs came with the slow air screws as opposed to slow air jets which makes life easier. I have a quiet road where I go, rather than annoy the neighbours where I can ride up and down, do plug chops and adjustments.

To help others if they do simmilar, The jetting I ended up with is as follows:-

#155 main jet, #50 pilot jet, ELS needle (4th groove from the top) I started with an ELT needle but had a slight fluff at 1/8 throttle so changed to ELS and it cured it.

here's to a warm dry summer!



They say a custom build is never really finished… that’s a true statement! while the four cable throttle worked really well… it was just a little too slow for my liking, taking just more than a fist full from closed to open. Also, after buying a clutch cable from Venhill for the Guzzi and being impressed with how much lighter it made the clutch, I decided to buy some of their teflon lined conduit, and some of their flexible wire rope as opposed to cable. That has made a significant difference to the feel of the throttle, especially as I extended the liner into the adjusters and throttle housing. I also incorporated a positive stop for fully open on the throttle, save straining the cables. I always enjoy silver soldering and watching the solder flow into the gaps to make a seamless joint! I did have to buy some more sticks of solder as I was getting low… £10 a stick now! it used to be £1 last time I bought some!



I have been doing quite a few miles before I put the bike away for the winter and getting used to it. One thing that annoyed me was the feel of the front brake… It was quite soft and somehow just lacked the feel I have with the Ducati’s. I looked on Ebay and thought I would give one of these radial master cylinders a go. They are quite neat in that the adjuster alters the pivot point of the lever so you can adjust the lever ratio! much better feel now!
