so go buy it at the Honda dealer then. im just saying its out there thats all.
i needed other KTM specific parts so the shipping to VA ($21.00) was amortized with the whole order.

Honda dealer won't cut me any slack on the price either,,,they all want their $10 shipping,,,just been wondering if there's a cheaper place to buy it but that seems to be the price for that kit,,,I didn't realise it had the two syringes thought it was just one,,,,,,

Just an update with my experience. Tried it with syringes 50ml, never really got enough pressure (too large piston size ?) and tubes I had weren't a good fit - oil seemed to leak from bleed nipple thread etc etc - my own cheapy set up..... Maybe for all the time & mess better to buy a kit.

Anyway didn't take any notice of the bleed nipple on slave cylinder till later - put a tube on that pressured it then released the bleed - bingo - tube shot off - oil everywhere but nipped bleed up quickly and seems to have done the job - so my suggestion try the top bleed first if there's air in it. If you're just changing oil and no air in system can feed reservoir and pump it out the master cylinder via a simple tube & drain the 'conventional' way till clean new oil comes out.

Mixed slave & master cylinder up above !
If I was to do it again - Looked at picture of kits and the syringes seem a smaller diameter, not sure you need 50ml either so a longer narrow syringe to increase pressure - wondered if a better bleed screw would help to stop it leaking and get a better tube fit. A

Bumping this old thread as I did a bunch of work on my bike over the weekend. 1 bottle of HYDRAULIC FLUID 75, 100ml was plenty to clean out the clutch.

All the best and thanks for a great article!
