This is a 100cc/90cc 2-stroke piston kit. The piston has a 52mm diameter and has a 12mm gudgeon pin. Fits engine numbers 1P52QMG.

You will receive the items shown in pictures 1-3. The Piston Guide diagram in picture 4 is just for information only. The kit includes one piston, two piston rings, one gudgeon pin (12mm) and two circlips.

Many Chinese parts crossover to fit other engines so please check the dimensions and pictures to confirm this kit's suitability for other models. If the dimensions and appearance of this piston matches your existing one, then the chances are that it will fit your engine.

How do I find out what my engine code is?

Engine codes are normally etched into the engine casing on the lower left hand side. If you have a foot operated gear shift lever, the code will propbably be found underneath the lever itself. Sometimes you will find that there is more than one code in this location. One will be the engine code and another will just be a batch number. The engine code will be the only one that has letters as part of the code, whereas a batch number is usually just made up of numbers and will be much longer. Mini moto and petrolscooter engines do not normally have an engine code.

Specs

• The piston has a domed top.
• The piston may be supplied with either a textured or smooth top. Having a piston that has a differently textured top will not affect the performance of your engine.
• Features two windows on one side of the piston
• Does not include top end bearing
• The detailed dimensions are listed at the bottom of this page.

When should I replace my piston kit?

If your engine is hard to start, burning oil, low on compression or simply seized and won't turn over at all, you may need a piston and ring set at the very least. Remember you will need head and base gaskets where applicable when changing pistons or piston rings.

Key Features

• This piston kit has been precision engineered to ensure it fits your existing cylinder
• Replacing just rings or bearings can be a false economy, buying a complete kit saves time and money

What is a working day?

Working days for delivery companies are Monday to Friday, excluding bank holidays.

Can I use a PO Box address?

If choosing 'STANDARD' shipping, then PO boxes are acceptable. If choosing 'EXPRESS' shipping (or if this is the only option), then PO boxes cannot be accepted as UPS and DPD can only deliver to full addresses.

When will my item be despatched?

We do our absolute best to despatch all items within one working day (Mon-Fri, excluding bank holidays). Due to the time difference between the United States and the UK, this usually means that we will receive and despatch your order on the working day following purchase and cleared payment.

Some items may require a pre-delivery inspection or build service which can delay despatch until the next working day.

Sometimes payment issues, fraud checks, adverse weather and other unusual events can cause a delay to despatch that is beyond our control. If you require something absolutely urgently, we always advise you to call us on +44(0)2476 455893.

Who will deliver my item, and how long will it take?

We use Royal Mail AirSure, UPS and DPD to ship our items to the United States, Canada and South America. Royal Mail is priced as 'Standard' and UPS or DPD is priced as 'Express', available as an upgrade where applicable.

Tracking will be provided, although the Royal Mail tracking is less detailed than UPS/DPD tracking.

Delivery times: (subject to customs or other delays, which can sometimes add up to 2 weeks in rare instances)

• Royal Mail AirSure (Standard): 3-15 working days (basic tracking)
• UPS/DPD (Express): 1-3 working days (precise tracking)

How can I get help with shipping or tracking?

Please send us an ebay message, or call us on +44(0)2476 455893 for any questions that you have about shipping.

Shipping is not listed to my destination, can I get a quote?

Yes! Some items are difficult to price for worldwide shipping due to various reasons. Please contact us with your full address and details of which items you are interested in.

Who pays customs duty and charges?

As the customer, you are responsible for any customs duty or charges incurred in your home country. However, because most of our items are low value, they are almost always exempt of any customs duty to most customers. We ship many items each day to the United States, Canada and South America and we are in good standing with customs as a trustworthy supplier. We almost never hear of any customs difficulties whatsoever. If you are unsure as to whether an item will incur any duty, please contact the customs authorities in your own country.

What is the basic returns policy?

We allow returns of unused, undamaged items for refund or exchange up to 30 days from when you receive the item. Exchange or store credit may be offered after this time.

Buyers in the United States, Canada or South America may find that it is not cost effective to return unwanted items. This is because the shipping back to the UK may be more expensive than the value of the refund, particularly for low value items. It is usually far easier to resell the item in your home country, and many buyers realise a profit by doing this!

What is the returns process?

1. Open an ebay returns case.
2. Package your item for safe travel. Include a note with your name, ebay user ID and postcode.

Who pays for return postage?

The customer covers the cost of return postage. We will only be able to refund this where we have made a picking error, or otherwise made a mistake that has led to the return. If you believe this to be the case, you need to contact us before returning the items as we may need to send one of our couriers in to pick the item up.

For items that are simply no longer required, unwanted, or that do not fit your bike, we cannot refund the return postage due to the extremely low prices that we offer across our range. There is simply so little margin that it is not possible for us to cover this cost.

We accept payment online by PayPal. You can either pay with a paypal account, or using a credit or debit card (account not required).

If you prefer, you can call us and pay for your order by phone on +44(0)2476 455893. Please have the item number to hand, as shown above in the green bar.
