Z1R Resurrection
Hello All,
I bought my Z1R back November 1989. I swapped for my SR650 and £500.
It was Moriwaki tuned and was pretty quick. At first I thought the clutch was slipping cus the rev's went up with a twist of the throttle without any extra forward movement.
Then I realised it was wheel spin as I went passed a car and started broadsiding, not a knackered clutch. It was November and the roads were a bit slippery, so that didn't help.
About a year later some t**t in an XR3 hit me. I was U turning outside my mates. I looked, as you do, nothing coming, so turned round. Next thing I know I'm in Hospital.
At the scene the car skidded for 25 metres and knocked my bike 22 meters up the road. I bounced off the wind screen. They found fibre glass from my helmet in it and the roof was all bent so the car was a write off. All I had was a broken ankle and a head ache and a broken Zed. I recovered and fixed the Zed which wasn't too bad really. New swing arm, rear foot hanger tubes and points and cover. It did have Dyna ignition but that got smashed, so I put points on it. The rest was cosmetic
The accident investigators blocked the road some time later to simulate the accident and they reckon the XR3 was doing over 70 mph.
A brilliant bike. Loved every mile. I'd been running it with bell mouths on though and no air filters. Big mistake. Bell mouths stop bumble bees getting sucked in but abrasive dust took its toll.
It started smoking, which is a filthy habit. It was 1996 and I'd just finished building my other bike so I took the Zed off the road with every intention of repairing it, so I dismantled it and stashed all the parts carefully. The cylinder head was quite bad. Fins broke off from the accident and tappet clearances on minimum.
As life continued, my journey through it didn't give me the opportunity to work on the Zed. When we moved house my mate stored the Zed for a few years, then I got it back, but still didn't do anything to it. My daughter started university in 2016 for 3 years and I thought "Right! That's it. I'm gonna do the Zed before she finishes uni". It was great going through all the bits. I'm glad I stashed it all so well. You know how these things go. There’s a vital part or parts missing that would put extra expense on the project, but I'd got everything.
I was playing in a band which took a lot of my spare time and was one of the reasons it took me so long to get round to the project. The first thing I decided to work on was the carb’s. Back in 97 I’d stripped ‘em down cus the Zed had stood with fuel left in it for a while before I dismantled the bike. The petrol had evaporated and left a kind of lacquer residue behind, so I’d started cleaning them up but that’s as far as I’d got. Fast forward to 2016. I like carburettors. They’re nice to mess with. I managed to clean all the nasty off and got em back together and they look great. I just hope they work as good as they look. Mind you, all the carbs I’ve ever messed with, I find that as long as they’re all clean and nothing obviously worn out they work. I even balanced them. I come across this somewhere. Get 4 ball bearings Ø3 or Ø4 and put them in the intake against the slide. As you raise the slide slowly with the tick over screw, the ball bearings drop through. . Adjust the slides so that your balls drop simultaneously when the slides open. I know each cylinder sucks different, but it’s got to be a good starting point from a rebuild. Oh yeh! DON’T do this with carbs on the engine. You don’t want balls in your head.
