It's the side with the cams facing out isn't it? But that's number 4 when the timing marks are correct to the manual
-
If pointing in travelling clockwise... The intake cam will now open the intake valve.... Or am I thinking this wrong
-
Aha so the one pointing in is the one I wanna back off a few degree and set to spark
-
On a gsf1200 when timing in the cams as per the picture (or as per the manual) as Pistons travel in pairs, which should be under compression 1 or 4? I know the coil sends a spark to each, one being a wasted spark. But I'm trying to time in a magneto.
I've done as per manual but both cylinders look to have both sets of valves closed. One has the pointy part of the cam lobe, facing outward of the cases ( ie ex facing the exhaust and in facing the carb) other has the lobes facing inwards toward each other!
Logical to me says, motor spinning in a clockwise direction, the lobes facing out are under compression as intake has just closed and the next cycle exhaust will open.
But im getting nothing.so double checking in accordance to the manual, which should be set to tdc and under compression when timed following the manual?

It was built for the bike, other than the shock I have been a little too stiff for my liking, .... Well.

I'm waiting for the postman to bring me parts to fire it up, had trouble finding a piston spring for the carb but got it now, I've had to cut away the mounting for the alternator so I can gain access to the distributor cap to time it! I'm hoping I get a chance to try to fire it around Christmas provided I get a new carb rubber as mines split with something leaning on the carb.
Ive still got the sidecar chassis and seat, I'm trying to get the bike running first so I can at least use it as something more than a door stop. Not gonna paint it just get it running and ride as is for now.
Once ive had a bit of fun I'm gonna start construction of a new body for the car, .... At the moment it's just a chassis

Cheers fatbloke, the rubber hasn't perished just snapped in transit with something leaning on the carb

The carb rubber... The rubber that secures the carb to the head, has snapped on my engine. What others are a direct replacement and from where? It's the outside left cylinder as sitting on the bike
engine is gsf1200

A couple of older build pics
yeah.... It was one of those till I got grinder happy and began personalising it
-
a certain Mr Sands would be proud to produce something like that.
tasty tasty.
was hoping more Mr ness lol was going for a 70's digger feel about it

You'll not end up with weakened mounts boring 2mm out lol

Common as muck, not great looking, but as said, great for pinching their engine and wheels from.
Good as a commuter/daily rider. Same with the teapots IMO
-
Yea it's a velorex magneto, just for the hell of it! Carb is an SU. Probably producing less than a b12 but it's a hard tail frame, engines overkill anyway.

Don't need them without a chain on
theyre in the shed somewhere waiting to be fitted
