Sable's Suzuki GT cafe racer

**Sable** · 10th December 2011, 16:40

1978 GT250 X7. Braced swingarm drilled disc VFR400 brake caliper and master with custom made braided steel line. Koni shocks. Clipons. DNA pods
New paint all bearings replaced new fork seals.

To do:
Adapt ZXR750 rearsets, install indicators tail light and mirror, drop instruments, attach seat foam, chop up RG250 chambers to suit.

Motor comes back from being professionally rebuilt on the 16th with oversize TS125 pistons bringing it to something like 290cc, stage
2 porting and custom made fibreglass reeds, squish correctly set etc, port heights matched.

Can't wait.

Will update as I progress

Keep the faith!

Put a Impulse motor in it! With a 4-into-4 system!

Back in the day they said the X7 was the first 100mph 250! A classic bike!

The last iteration of this motor with the standard size ts125 pistons and ports cleaned up not modified did 200 down the back straight of manfield with standard pipes so I see no reason to doubt it

**SPman** · 13th December 2011, 19:25

Sounds good.

I really should do something similar with my '78 GT250.......

**F5 Dave** · 15th December 2011, 15:57

yeah I had TS pistons in mine back in the day. Took me a while to get running without blowing head gaskets until I got some copper ones made, but I didn't correct the squish clearance so lost some potential power there.

Have to be careful with the cranks. they aren't over engineered.

**Sable** · 18th December 2011, 05:48

Yeah the cranks are pretty shit. Next time I'm gonna see if I can get some CR125 rods in there so I can use bigger bearings

**F5 Dave** · 18th December 2011, 06:55

if there is room to bore the crankpins out then a bigger big end bearing must help, presumably they are captive pins on one side so would have to bore the original away. You'd want to have a decent engineer attempt that to get it straight & strong enough for a twin.

Great bikes! This is a photo of me with our eldest son and his X7 in the mid-90's. A fantastic machine and I regret selling it. As fate would have it, I've discovered where it is. It hasn't been used for nearly a decade and the current owner has also amassed several boxes of spares. He's not currently interested in parting with it, but I'm working on that!!

Enjoy!!
