This TSP Top End Rebuild Kit will fit KTM and Husky TBI 300cc Models. This is a complete top end rebuild kit that comes with everything you need to rebuild the top of of your 300 TBI two stroke.
The TSP Top End Rebuild Kit includes:
- Meteor piston kit with a B size piston. Piston kit includes rings, pin, circlips and a high quality cast piston. These pistons are made by Meteor in Italy and are THE BEST available. The current Meteor piston features a special coating on the crown to reduce temps of the incoming charge and reduce detonation. This is a cutting edge piston developed especially for KTM.
- Top end gasket kit. Includes two gaskets to achieve the stock 0.60mm thickness base gasket, power valve cover gaskets, copper washers and O-rings. All O-rings are the correct size and made from the correct material, unlike the cheaper aftermarket kits.
- TSP little end bearing
- EZ clips free of charge ($20 value) for ease of piston installation
TSP rebuild kits are put together by TSP using parts sourced direct from OEM manufacturers in Japan and Europe. The parts we select are THE BEST available for each make/model and many are the exact same parts as the genuine items.
Piston sizing: ideally you should measure your bore with a dial gauge to work out the correct piston sizing. If you cannot do this then a general rule of thumb is to use a “B” size piston on any cylinder that has 50+ hours on it. “A” size pistons are best suited for new cylinders or newly replated cylinders.
