The secondhand carburetors & parts turned up yesterday.

Externally they were in slightly worse condition than the ones fitted but internally much better, all the jets came out and no 'varnish' from stale petrol.
One diaphragm is a bit crumpled for some reason so I'll take one from one of the originals.


I scrubbed them clean with turps then brake cleaner then popped them in the ultrasonic cleaner, it still surprises me how dirty the water gets......


I'm only using the float bowl gaskets, float needles and screws from the Chinese kits, after having a Chinese jet break I'll stay with the Japanese jets after ultrasonically cleaning.

Float heights were way out, the Chinese float needles were slightly longer and fitting those along with some fine tuning got the heights set correctly.

I now need to replace the fuel pipes which means making a couple of 90degree bends (insert a former inside & use a heat gun).

Hopefully.......I'll get it running without issue this time !!

Colin

Fitted the cleaned carbies yesterday and finally.......success ! It starts & runs OK but needs some fine tuning.

On to the next problem.
With a meter on the battery there seems to be no charge when the bike is running. Seems that the standard regulators fail regularly so time to investigate.
Removed the rear bodywork and found that the regulator had been changed in the past. Slightly different model but some very neat wiring to correct plugs to join to the harness.
Amongst the job lot of parts there was a new Chinese regulator so I decided to fit it and see if there was any change.
Still no charging but the regulator became warm as did the wires from the alternator !
Re-fitted the original and basically the same problem.
I'll have to check the wiring from the regulator to earth and regulator to battery, something is NQR.

While checking things over on the bike I found that the sidestand switch has failed. I'm not sure, but I guess it'd be part of the roadworthy test so need to track down one from a wreckers.


Colin

Carried out some wiring checks, all OK.
Started the bike and a healthy voltage across each pair of wires from the alternator.
Re-connected the rectifier, checked output and nothing !

Seems the regulator fitted has failed and the 'new' one in amongst the job lot of parts purchased doesn't work.
Interestingly the new one is from the same supplier who sent the wrong fuel pump (mental note not to use them ever again).

Replacement ordered, hopefully this is the last problem. Otherwise I'm thinking of taking up another hobby, maybe stamp collecting.


Colin

The AliExpress regulator/rectifier turned up.
Once fitted the battery was charging so just need tyres now.

I might get a cheap digital voltmeter so I get a warning when this regulator karks it, they seem to be a frequent failure point unless you spend large amounts on a MOSFET reg from a reputable supplier.

A customer has just offered me an '88 Honda Transalp, looks like one of my boys might buy it. I wouldn't be allowed to buy it unless the Suzuki gets sold first.

Collected the Transalp tonight.
It's been standing for 6 months so needs checking over and a service.
A few bumps, scraps & splits in the plastic panels but the young bloke is happy.
58K on the clock and only $1K.

Hopefully he has less problems than I had with the Suzuki !


Colin

Tyres fitted to the SV650, that's almost doubled the investment in this bike.

Next a roadworthy, mind you the weather is changing so that may go on the backburner. Maybe a permit and a few local rides to a 'place of repair'.
