March 8, 201511 yr so.... seized my 2011 250 today. wheres the best/cheapest place to buy the parts, splat shop seem to have a huge markup on parts, a single piston ring for £23! i can buy a full set for my leyland tractor for that!
March 8, 201511 yr Splat shops 250 piston kit (£128.00) is about the same price as a Beta or Gas Gas piston kit. But If you think the Layland tractor parts fit go with them. You may just need a very big hammer to get them in though.
March 9, 201511 yr I've always found splatshop's prices to be very good, plus Chris's knowledge is priceless when you make a balls up.
March 9, 201511 yr compare the number of leyland tractors bult and the number of shercos.. compare the number of rings sold each year and thats why thier 23 quid.. which considering 20% of that is tax how much profit does the vendor make?
March 9, 201511 yr Try an Apico or Wiseco dealer. I am not sure what make the piston is in a sherco, quite likely a Vertex or Mahle. If you can find out may be able to get them through car engine rebuilder. Splatshop are a very good supplier, the high price of the ring is almost certainly not their fault. It is probably the structure and low volume of the trials spares market that is the problem. I can buy a set of 6 pistons complete with rings etc for a 4 litre engine, ie about £50 each yet a 125 cc piston for a trials bike is about £150
March 10, 201511 yr S3 made barrels and pistons for that year of Sherco, They just were not branded as the fancy ones S3 does. In general Sherco parts are cheaper than every other brand especially Beta and Montesa. How on earth did you sieze the bike up, You will probably need more than just rings, Probably re plate and a piston too unless you want to bodge it like a tractor.

March 15, 201511 yr Author Lucky you if it not rattling too much! yes i imagined starting it and it sounding like a 4 stroke twinshock. trialled it today and it runs like a dream!
