piston change

[RinB]

you could try a replacement "mahle" type piston with thin rings like this one http://cgi.ebay.co.uk/LAMBRETTA-GP-200- ... 3ef52af71d
or a slightly more upmarket one like this http://cgi.ebay.co.uk/LAMBRETTA-GP-200C ... 1c0c7934ae
the asso pistons are now aproaching £90 (the AF web site is way out of date)

both these pistons are cheap cheap,both quality and price you really need one from mr broadhirst or an af one

I recommend dont use these pistons on any stage 4 tune the rings cant handle it
I know from experience

Go the ASSO route or Mahle Piston with Asso rings costs £65 ish
Remember the Asso 66mm has the 3mm off the skirt, so need to take this into account
when doing the tuning Mahle piston doesnt.

Im at present doing 4 200cc st4 for people and this is the route Ive gone

when tuning any two stroke I would always try to get a nice jap piston, for all the following reasons (thin rings, light weight, better piston strength, more accurate machining, easy availability, etc.etc.etc)

is that for the ts200 you said about ? as the yam dt/it piston is 66mm and some kawasaki ones are 66mm too

Yamaha IT175/YZ175 pistons are very good and will only fit a TS1/Monza 200 kit when using a 115/116 rod because of a different deck height.

unless you wanna top and tail or stroke it to your personal needs

i,m sure bazman ran the mahle piston.............

I certainly did sean
On hols at the moment so would have replied earlier.....

[Tosh]

thanks chaps for all the replies,going to go the mahle route but what still puzies me is how do i make sure i get the right size piston/rings or do i take the barrel with me when i go to buy one

[bazman]

You need to measure the bore of the barrel and get piston to suit

[Tosh]

thanks bazman for that ,i bet sean thinks i`m never going to get hold of him and try to sort a tune out
