Mitaka oversize pistons for GT186?

[Nic]

Hi guys.

Does anyone know where I can get oversize pistons and/or rings for a GT186 kit? Just back from Italy. Scooter ran well and got me back, but a "quick" strip down in Adria showed a ring gap of about 4-5mm. The grooves were pretty carbonised and the peg had all but disappeared.

Many thanks, as always....

Hi Nic. I'm glad you made it back. Those 9 hours we spent in the workshop paid off.

Try Grampian Motors for Matika pistons.

Not the cheapest, but they are fast, things are in stock, and it is not a fake.

4-5mm is a very big gap the ring must be worn extremely thin. Can you post some pictures and measurements, it is worth checking the bore too. How many miles have you done on this piston?
