Piston - cheap but is it any good.

[ArmandTanzarian]

After a heat seize (or two) I need a new 66mm piston. Luckily the Indian barrel is fine.

Are these pistons any good? They're cheap but that's no good if they're made of cheese or have a size tolerance of +- a mill or so!

Might be worth checking his e-bay feedback see if theres anything against his pistons, I have personally had a few things from him and its decent gear, still needs a little fettle as it all does but on the whole not bad gear.

nice piston.how many do you require sir?

[Supereibar]

Armand, if you permit an oppinion. Indian SIL pistons are a good option in a Spanish standard machine. I have been using one trouble free for over 2000 miles, also donlambretto from the forum has used one in his lince 200 and it goes like a dream. Aparently the quality of the SIL made ones is very good.

Thanks for the feedback chaps. I'll order one. (although I suspect that Joespeed's opinion may be a little biased )

Now for a supplementary question.

My current piston has had a couple of mm sliced off the bottom of the skirt to increase the inlet duration. Since the scoot goes pretty well, I'd like to do the same again. Is this a job I can have a go at myself with a hacksaw, some course wet'n'dry, WD40 and a flat surface or is it best left to a pro?

you will be able to diy just with a file, a piston files really easily

I use a Black and Decker band file. Use the wide option and its a few minutes work- good finish as well

when I cut a piston skirt I usually put a little insulation tape on the piston skirt, then cut to just shy of the tape with a hacksaw, followed by filing / emery cloth etc. up to the tape

its realy very easy

As cezeta says they file very easily, I use a bench file which screws to the bench and you move the piston Very easy to use and Three minutes is equal to 3mm removal from the skirt, leaving it very square and flat, then finish with a half round file then wet and dry...
I have also used the Hack saw and tape method, but dont slip!!!!

Been thinking about these. Is that a handy tool for the workshop? What's the wide option?
