Bought a 2 smoke!
Discussion
Looking at old pics, and got an itch when looking at photos of my nsr250,
Bought this as a non runner, cleaned the plugs and went third kick!
Spent today degreasing and cleaning, it's coming up nice, needs front mudguard painting, and new graphics on one side panel.
Going to put some proper race pipes on very soon.

The bloke who I bought it off had a stroke, and was giving up, he must have been mid 70's!!
Turns out he used to race a bit bitd, like me self!
I think a PV inspection and a re ring will be on the cards , maybe thicker base gasket and head gasket delete.
Raises the ports and lowers head to compensate.
I'll do a few miles on it next week perhaps, make sure I like the concept (again) , after my gsxr1000k6 it's gonna be odd...
But the 15mile cross country commute might? Be more fun?

Not advisable.
Speak to Sean at TTW and do it right.
Get a selection of Base gaskets to achieve the correct squish.
IIRC you can't run these without a headgasket anyway. And all that does is move the port timing which ruins the power curve of a very good engine. Might seem more powerful with the harder hit but in truth does nothing.
If you want to improve the motor then do a full top and bottom end refresh including crank. Set the deck heights correctly and new single ring pistons. have the powervalves re pinned or get newer items.
If you are really feeling flush a set of Tyga pipes, domed and O ringed heads and a zeeltronic ignition and powervalve control unit will transform it.
Make sure that the powervalve cables are set correctly and you'll have a flyer. 65bhp is about the max but no messing around with porting or port timing or such. Reliable if jetted correctly and an absolute hoot.
Enjoy!
I mean by head gasket delete, an O ring conversion, Steve Clitheroe did my CR500 bitd for me with a re profiled squish.Speak to Sean at TTW and do it right.

Was worth about 2bhp.
There is a factory Suzuki kit base gasket, must be a reason they made it?
I am leaning towards Jolly Moto pipes, my first choice would have been Derek Huxley, he was the man but I think pipe manufacturing has took a back burner for him now.
His pipes are works of art.
Thanks for the info, I will give the Tuning works guy a shout
Took the plunge (literally) and dropped a caliper in the Citric (very mild food additive)) acid overnight, results are pleasing, i've chucked the whole brake system in now. This is the stuff i used on an 80's BMX frame (common practice) it didnt even touch the stickers! so thought i'd give it a try..
Shes up and running, the new pipes have got the jetting to suit, and it sounds the bizz, really sharp bark to it, Best stick some brakes on it before i try it out, waiting for the side panel to come back from the graphic man, what do we think to powdering the wheels Black??

black might be easier to clean but white is the correct look with the suzi blue.
White every time....
And don't think what jets are in one carb are right for the other. It's 2 separate 125 motors and needs to be jetted as such. Power jets are asymmetrical as well.....
Its got different emulsion tubes (weaker) richer jets 280/290 Different cylinders as you say, these are the base settings that Jim Lomas has given me.White every time....

Looking really well, who remanufactured the number boards?
Got the side panel back from the decal guys, the long stripes are genuine Suzuki, the number board surround had to remanufactured, hard to tell which is old and new!

Gone with white on the wheels, rebuilt the calipers as they were dragging, quite corroded in the seal area, all cleaned nicely now, regressed head bearings they were notchy, vapour blasted the bottoms of the forks, mudguard with fresh paint looks a treat.
