Thanks for the confirmation, much appreciated.

Recently I purchased a rear rim and hub for a spoked rear disc bike. It claimed to be from a z650, however I could not think of a model that used this set-up and thought it from a Z1000 A1/A2 or maybe a Z750 B. Any help with identifying the model that this wheel might be from would be much appreciat...

I've been struggling with an intermittent misfire on my Z1B for a few weeks now and I thought I would share my findings just in case other Z1 owners have been suffering the same problem. Bike always started up OK but after a little while (say 4 miles) would suffer from an intermittent misfire and lo...

LondonZ1, Thanks for the words of encouragement and I followed your build as it progressed. It really has given me lots of inspiration to get moving. I also read the article in Practical Sportsbikes on your Z900 "Sanctuary". Fantastic stuff and I look forward to seeing the bike on the ZIOC...

http://i1072.photobucket.com/albums/w369/Kawasaki_man/KZ900-A5%20Project/kz900-a5_6.jpg Cleaned the carbs out and started the engine end of May, all sounded fine, decided that engine should be OK and project can move forward...very slowly. (Tank from Z1B, seat from Ikea curtains!) http://i1072.phot...

Thanks for the patience shown in dealing with these issues, but I'm now much more confident that the problem must have been caused by not having the cam chain tight enough during camshaft reinstallation and the end result being crank slightly out of position. I'll never know for sure. I guess the ea...

Thanks zed1015 for info about valve seat being correct. I totally agree with your comments about valve timing being the most likely cause of the problem, however I can say that I studied this very carefully when I first disassembled the engine in Nov 2011. When I bought the bike in Nov 2011 I decide...

Thanks for all the advice/help...Pistons are standard size and ART, cams would seem original, inlet lift around 36.33mm and valve clearance was 0.10mm on all inlet valves. All valves are new. zed1015 mentioned valve timing, that made me realise that the cam guide sprocket mounting bolts were not all...

I'm in the process of trying to reduce the oil consumption and smoke produced on my Z1B. Before starting the disassembly I check cylinder compression and all seemed well within spec. I've now removed the head and it appears that the engine problem is very likely to be due to excess oil running down ...

Thanks GB for the words of encouragement....Your project looks interesting also, I'll keep an eye on it. Current ideas are twin shock rear swing arm and at the front USD forks. If anyone has experience or ideas on what Twin Shock swing arm that allows a decent width rear wheel/tyre to be fitted and ...

The Z1 is a fantastic looking bike and my idea for this project is to use the bits that I think best describe the Z1 and use other parts where suitable. Z1 defining parts:- 1. Tank 2. Engine 3. Speedo & tacho 4. Duck Tail 5. Oval Rear Light 6. Side panels Modern parts to fit:- 1. Forks 2. Wheels...

The seller stated that the bike had Z1R front and rear ends (1978), hence the non Z900 appearance. I was not familiar with the frame number of the bike so did a check at the Z1 Enterprises website and it showed KZ900-A5 have frames from Z1F-510341 to 515578. The bike fits in this range Z1F-5136** an...

I've been looking for a suitable project bike for the past 6 months. The prices for tatty Z1/Z1A/Z1B have been just too high to justify a purchase for a project. However 4 weeks ago I came across what seemed like a perfect candidate, it is a KZ900-A5, first registered in 1977. I've now taken deliver...
