So, the time has come for an engine rebuild. Hopefully, it's being done as a practice of proper maintenance, but for many, it will be because of an engine failure. Whether the bottom end, top end, or both went out, the first step is to disassemble and inspect. After determining any damage done to engine cases or the cylinder, and arranging for those to be repaired/replaced, you're faced with choosing what internal engine components to buy, where to get them, and how much the costs are going to add up.

A full engine rebuild is a serious job and requires a lot of parts to be replaced, especially in four-strokes. You have to think of bottom end bearings and seals, a crankshaft assembly, piston, rings, clips, wrist pin, and the plethora of gaskets required for reassembly. If you're doing this rebuild yourself, or having your local shop do the labor, chances are you don't have a factory team budget to spend on parts. However, you know you want high-quality and durable parts because you don't want to find yourself doing this again anytime soon.

You could source all the different parts you need from different vendors to find the best combination of quality and affordability. But, it can get frustrating when 6 different packages are coming from 6 different vendors at different times, and each one relies on the next for you to complete your rebuild.

Wiseco is one of the vendors that has been offering top end kits (including piston, rings, clips, gaskets, and seals) all in one box, under one part number for many years. Complete bottom end rebuild kits are also available from Wiseco, with all necessary parts under one part number. So, it seemed like a no-brainer to combine the top and bottom end kits, and throw in a couple extra goodies to make your complete engine rebuild in your garage as hassle-free as possible.

Wiseco Garage Buddy kits are exactly as the name implies, the buddy you want to have in your garage that has everything ready to go for your engine rebuild. Garage Buddy engine rebuild kits come with all parts needed to rebuild the bottom and top end, plus an hour meter—with an awesome Wiseco hour meter decal—to track critical maintenance intervals on your freshly rebuilt motor. The kits include:

  • Crankshaft assembly
  • OEM quality main bearings
  • All engine gaskets, seals, and O-rings
  • Wiseco standard series forged piston kit (piston, ring(s), pin, clips)
  • Small end bearing (for two-strokes)
  • Cam chain (for four-strokes)
  • Hour meter with mounting bracket and hour meter decal

2-stroke and 4-stroke

Whether your machine of choice is a 2-stroke or a 4-stroke, Wiseco can help you with your rebuild. 2-stroke Wiseco Garage Buddy kits include everything listed above, featuring a Wiseco forged Pro-Lite piston kit. You don't even have to worry about sourcing a small-end bearing, that's included too. 2-stroke fans often brag about the ability to rebuild their bikes so much cheaper than their 4-stroke counterparts, and they'll have even more ammo for bragging now with these kits starting in the $400 range.

However, don't abandon your 4-stroke yet. Many riders cringe—and rightfully so—at the thought of rebuilding their 4-stroke because of the costs associated, but Wiseco 4-stroke Garage Buddy kits starting in the $600s takes a lot of sting off your rebuild project. They even include a new timing chain.

No matter what you're rebuilding, you'll be able to track key maintenance intervals for your fresh engine with the Wiseco hour meter and log book that's also included in the Garage Buddy kits. And with the exclusive hour meter Wiseco decal, you'll look good doing it.

Ease of ordering

Wiseco Garage Buddy kits come with the listed parts boxed up in one box, and listed under one part number, which makes it nice to not have to worry about if you might've missed something when ordering. Simply find the single part number for your model, order, and you're on your way to brand new performance.

Quality Performance, backed by a Limited Warranty

Ordering convenience doesn't make a difference if the parts do not provide quality and reliability. Wiseco crankshafts are designed completely by in-house engineers, who determine all assembled dimensions, clearances, materials, and specifications. These specifications have been determined from R&D tests such as hand inspection, dyno, and failure analysis.

Once Wiseco cranks have been manufactured to exact specifications they are batch inspected, and critical tolerances and dimensions are measured. Major inspections and tests include crank run-out and trueness, because they must operate within a strict tolerance to last long and perform well.

Bearings are another critical point of inspection. Wiseco has worked to build relationships with top-tier bearing suppliers to provide a long-lasting, low-friction, flaw-free product. Debris in a bearing can lead to very fast wear, and Wiseco makes it a point to inspect batches of bearings for cleanliness and proper operation.

As part of the design and engineering process, prototype crankshafts are hand inspected and dyno-tested at wide open throttle for 4 consecutive hours. This is a benchmark test, and new crankshaft designs must pass it before to be deemed worthy for manufacturing.

Watch our crank R&D and inspection process.

A Warranty on Engine Internals?

Yes! Wiseco is committed to providing performance and reliability in all their products. This is why Garage Buddy kits come with a limited warranty. Rebuild your engine with a Garage Buddy kit, and your new Wiseco components are covered against manufacturer defects for 90 days from the date of purchase, or 10 hours logged on the hour meter, whichever comes first. Check out all the warranty details on the detail sheet in your new Garage Buddy kit.

Forged Pistons

The top end kits included in Garage Buddy kits feature a Wiseco forged piston, which are designed, forged, and machined completely in-house in the U.S.A. Four-stroke Garage Buddy kits come with a Wiseco standard forged piston, which offers stock compression and more reliability and longevity, thanks to the benefits of the forging process.

Two-stroke Garage Buddy kits include a Wiseco Pro-Lite forged piston, which is the two-stroke piston that has been providing two-stroke riders quality and reliability for decades. Many applications, two and four-stroke, even feature ArmorGlide skirt coating, reducing friction and wear for the life of the piston.

Forged aluminum has an undeniable advantage in strength over cast pistons, thanks to the high tensile strength qualities of aluminum with aligned grain flow.

All pistons are machined on state-of-the-art CNC machine equipment, then hand finished and inspected for quality. The forged pistons come complete with wrist pin, clips, and high-performance ring(s).

Lastly, all gaskets and seals are made by OEM quality manufactures. Sealing components are not something to ever go cheap on, because no matter how high-quality your moving components are, if your engine is not sealing properly, it's coming back apart.
