Hi Guys, Back in the saddle for another go at getting the Suzonda running and finished.....

I have found the love again, so setting to on the build.....ordered a new igniter unit, just so everything on the spark side is fresh. A compression test showed 35psi on both pots...wet it read 40psi. Now I'm used to circa 100+ on 4stroke higher capacity engines so have no clue as to whether this number is OK...anyone shed some real life information please?

While awaiting parts I'm dicking with teh front guard....chopped down a CBX550 guard and fabbed an inner mount strengthener plate as I will use the existing fork lugs. The thing will be painted matt black to blend with the tyres.....I'm hoping for the fenderless flat tracker look....but practical when riding.

It still needs trimming etc

I'll be making progress reports as I go......cheers for now.

Small update:

The guard is now shaped and sitting close to it's final position....it'll be matt black to hide it. The excess alloy will be removed.

The lowest compression I've seen factory spec was on my 1984 JS550 twin Kawasaki Jet Ski. 115+/- 10 psi.
It ran pretty good with 105psi and 87 octane.
You have BAD compression.

If I saw 95psi, I'd probably try to get it started by turning it over quickly and seeing if it' would take. Otherwise, freshen her up and get it into the low-to-mid 100's.

I used to have 165psi on a GT750 and dropped that down to 155 after raising the exhaust port a little more.

30 PSI is not a real number... Try a different gauge and/ or try it again without pipes or carbs just to be sure one or other isn't blocked. Ebay cheap compression testers often show that sort of number. I threw one out and so did my neighbor. Different ebay sellers but the same crap dressed up to look like a decent tester.

Thanx Teazer, I tried another test wet and the psi raised to 40psi, so the gauge is not peaking out at 35 but still not entirely trusting the calibration/operation.
However, the thing fired up and ran on a squirt of juice in the carb throats...after I foundand cleaned a dirty/loose threeway CDi connector.
So whatever the compression figures are it runs....... :)

I'm not relying on the gauge, following many replies and stated figures. However, a dirty CDi loom was spotted and it fired up after 2-3 stabs on the starter. How it runs on the road is another matter, but it runs for now,
Thank you for your input.

Tear down begins...unpicking the loom, head & tail light units :/ Trying to remember to label the connections as well as photographing the installation.

I did uncover my oil tank cut n shut...still like how it worked out :) Just need to open a 50mm hole in the carrier to access the bottom AN outlet for the feed pipe access.

Will have it tig'd in a couple of places on the cage.
