Where do you get decent 18" tyres?

18" slick on Trade Me!

They were the bees knees when they were still making them. I pitched into a corner on the tarmac at Ohakea going fast and my seat bracket broke resulting in me falling off the inside of the bike. Luckily I had a fresh set of these on. I pretty well did a U-turn before I managed to climb back to where I should have been but the tyres just hung in there. Truly amazing grip, more than I was willing to consciously use.

I seem to remember they sometimes came new with cracked sidewalls. I wouldn't worry about that.

She's sorted for now. Problem is I've run out of money, I have a very very limited budget. Minor porting next probably, before the new piston...

New piston first is how I would go. Nothing like getting it going good before you start fiddling.

Edit: I have a small collection of brand new Suzuki rings from a few "bucket" models and the odd piston. Measure the piston and I'll compare it to what I have. My prices will be better than the shop, a lot better. I also have a spreadsheet of the dimensions of comparable pistons, some of which are better than others for various reasons so I could check that as well.

I'd be interested in your thoughts on the best piston choice for a GP100. I've read the very informative post you made about tuning the GP a while back and am planning on starting modifications at this end of the series this year.

Now that we've sorted the 18" tyre dilemma any suggestions for a 19" front to suit a GPz550 PC racer? Think its got a Bloodstone BT54 (err 39) on it at the mo.

You won't need to.....it got a near new BT39 on the front and a Dunlop501 on the rear! THERE IS NOTHING TO DO BUT RIDE IT!

I'm not familiar with the GP internals. If it's anything like a TS a good stock Suzuki piston is the RG400 rear piston. Slightly thinner rings and a bit lighter and better made.

A case of mistaken idenenty...was TZ350 that posted this.

having riden 4 of tz350's gp125 I can tell you that all the standard stuff from suzuki is good enough for this engine dont bother getting rg400 or any other stuff unless it is cheaper easier to get
suzuki agents seem to be able to get you anything you need
you'r best bet if you dont know to much is get a manual for it and build it up as a 125 not 100 keep it standard to begin (they are plenty fast enough on a tight track)
my one is 4 years old done 4 2 hour. finished every time never failed to finish a race unless I have broken something on me.Lent it to many people and found that a good rider can get it down to 30 sec lap time around Mt wellington (I cant get near that 38 sec) It hase done taupo twice last year Keith B wiped the field clear with it at Taupo in the last race (beat the only fxr down there so did 3 other gp125's in the last race)
dont underestimate a standard gp125
