Good to see you here Jim, and Thanks Kevin for confirming my rides, I have a memory like a sieve nowadays. I don't know if I'm retired yet, my combination of long service and annual leave ends around mid week next week, and then I'm "On the bench" which doesn't appeal at all, but after 10 years working for this company, I'm entitled to a "Golden Handshake" if they have to let me go, so I'm not going to blink first, I'll just keep hanging around and drawing pay until they realise that I'm "surplus to requirements" and let me go. As long as I can stay home and continue to sleep in each morning, and ride my bikes, while still getting paid, I'll take it.
Spotty and I got all excited last weekend with my GPZ1100, I'd found a supplier of 29mm valve shims and had replaced 7 out of 8 shims with thinner ones. We reinstalled the cams (easier to remove the cams than try to compress the buckets for that many shims) and set the valve timing. We got the compression tester out again, and .... nothing. Still no compression in cylinders 1 and 2, as opposed to 150 psi in 3 and 4. We checked the valve clearances again and we had plenty of clearance, so this weekend we'll be removing the head, and hopefully I'll just need a couple of new exhaust valves. I might take the head off my 1428cc KZ1000 engine (later model GPZ1100 head) and install it, we'll see.
Anyhoo, on Sunday Bob came over and picked up a K1 head, and after he left I decided that ride #25 was in order. It was a great day, sunny but not windy, and I had a great 103 mile ride, the furthest I've been on the VMax so far.

On Monday it was still sunny, but very windy. Being semi-retired as I am at the moment, I had no plans for the day, so when the wife told me that she had a doctors appointment, I decided that ride #26 was in order. I then decided to install the "Morley Muscle" Ignitech ignition with VBoost controller. While there were no installation instructions, it was a quick "Plug and Play" job, and I still had plenty of time to go for a ride, if the bike started.. Well it did start, the VBoost did it's thing and the engine ran OK, so I put all my winter bike clothes on, and headed north. I don't know why, but it felt a bit "Gutless" compared to the previous day. The first opportunity I had to hit the VBoost (which comes on around 6000 RPM, and all hell breaks loose) was utterly disappointing, the ignition was breaking down, just missing and farting, which was really annoying. Apart from that, at sane speeds it seemed to run fine, but really felt a bit "weaker" than with the OEM ignition. Not what I expected at all.
Anyway, it was a crappy day for a ride, the wind was really strong, so riding into it, it wanted to push my helmet into my face, and when riding across it, it tried to blow me off the road, so with the ingnition problems and the wind, I cut the ride down to 63 miles, and that was ride #26. I've sent Sean Morley an email to ask him what the fix is with the ignition, and if I need to send it back I'll be happy to install my stock ignition and have the VMax back the way it was, at the moment it's just too damn "normal", and I want my "Hooligan bike" back the way it was. Hopefully I'll get some more rides in soon.
