I don't like that option as the KX piston is flat topped and has an inlet skirt cutaway. I have done a couple using other 86mm pistons but they also require a rod change and a barrel spacer as the comp heights are different with 18mm pins. Just looked and industrial 18x25x22mm needle rollers are listed so might get away with just a spacer and from memory the PE uses piston end thrusts which may need some re-work. 
Don't know what has been done to fix the pin difference with the KX500 piston but I vaguely remember something about crowded 3mm rollers. Not something I would want to do but was used in 2 strokes back in the dark ages. The piston could also be machined to take a 20mm pin which isn't that hard to do just a bit costly.

 Most of the other 86mm pistons I've looked at have a big inlet skirt cut away ( it400, Seadoo ect)  .Good shout on machining the piston, could I move the postition as well to get rid of a spacer?  ( can you remember what pistons, spacer you used)?

A customer in the States has pistons for PE 400's

"I have 86 and 85.75 mm. With the 85.75 a person would have to fit the rings to cylinder because they only make the rings to 85.5 & 86 mm."

I can put you in contact with him if you like.

That would be good thanks, steve . bird  at williams f1 .com

 I've read about using a KX500 (86mm)  In a PE 400, But what about the small end bearing?  PE 20mm Pin 25mm rod.  KX Pin 19mm  . Can't find a bearing 19 x 25 x 22.
  Thanks,
 Steve,

I've had some success with melting a staple into the plastic, there are proper machines for it but I used a blowtorch and soldering iron.  https://www.youtube.com/watch?v=dsoxXsksNvY

Pe 175 T. Just about to rebuild my crank and the new crankpin is hollow from one end with a oil hole drilled to feed the big  end brg.   Recommendations on what side to fit the pin from and orientation of the oil hole??   Thanks.

Tech Talk / Suzuki PE ignition timing

« on: April 06, 2017, 07:07:00 am »

 Good evening all, I have a PE 175T and a 400 and a few spare CDI boxes with no part number showing. Does anyone know the different timing specs as the only way I can see of sorting them is to run them and check with a timing light. The 175 seems to be a mix and match of parts, the magneto it came with made a good spark but was approx. 90° out? A visually identical replacement has the correct timing. Further investigation shows the magnets on the 90° one out in backwards? as in N/S instead of S/N ( checked with a compass). Any help appreciated .

Yes sunny at the weekend, that will be our summer gone   In Andover near the bottom of the small island. Near Salisbury plain that is great for trail riding even though it's a bit flat. Rode a couple of times in OZ, once up in Cairns / Port Douglas and once a couple of hours north of Melbourne.

Evening all, 54, race old clutter as well as modern stuff . Current bikes 250 ktm xc 2012, PE 175, PE400, KDX 200 89, KDX 200 86, KTM 520 03 in a 450 07 SXF frame.
Have access to all the toys at work and made a YZF shock fit the 86 KDX, YZF Fork internals in old KDX forks, auto clutch for the KDX and new top yokes. Enjoy working on them as much as riding. Great resource of info you have here, hope to maybe add a small bit.
 Steve.
