Wiseco's Garage Buddy: Complete Engine Rebuild Kits for Dirt Bikes!


Kevin from Wiseco

Wiseco's new Garage Buddy engine rebuild kits offer everything you need for a bottom and top end rebuild. From the crank to the piston kit, and even an hour meter to track maintenance, everything is included in one box. Here we take a look at the components included, and the technology behind them.

Garage Buddy Kit

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, wristpin, 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.

Four Stroke Engine

Rebuilding a dirt bike engine is an involved job, requiring many parts to be replaced. Missing one seal or gasket can put the whole rebuild on hold.

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 manufacturers 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.

Four-Stroke Piston Kit Bottom End Kit

Top-end piston kits and bottom-end kits come together to create Wiseco Garage Buddy rebuild kits.

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 a Garage Buddy specific decal—to track critical maintenance intervals and identify your rebuild as a Garage Buddy rebuild. 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

Open up a Garage Buddy kit, and you'll find all the components you need to rebuild your bottom and top end.

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.

Garage Buddy Two-Stroke

A Wiseco 2-stroke Garage Buddy kit includes all the parts you'll need for piston and crankshaft replacement, plus an hour meter to track your next maintenance intervals.

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 included in the Garage Buddy kits. All Garage Buddy kits include a specific hour meter decal as well, which is important for the limited warranty to identify the rebuild as a Garage Buddy rebuild.

Garage Buddy Four-Stroke

A Wiseco 4-stroke Garage Buddy kit includes all the parts you'll need for piston and crankshaft replacement, including a cam chain and an hour meter.

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.

Complete Engine Rebuild Kit

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.

Wiseco Crank Assembly and Main Bearings

Wiseco crankshafts and bearings are manufactured and tested according to strict tolerances and clearances, including run-out and trueness. Crankshaft designs are also tested for 4 hours at WOT.

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 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.

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.

Garage Buddy Limited Warranty

Open up your Garage Buddy kit and you'll find a detail sheet on the warranty on your new components.

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. Some 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.

Read more about our forging process here, and get all the details on our coatings here.

Wiseco 2-Stroke Forged Piston Kit Wiseco 4-Stroke Piston Kit

All Wiseco pistons are forged in-house from aluminum. Some pistons may also come with ArmorGlide skirt coating, and some 2-stroke pistons may already have exhaust bridge lubrication holes pre-drilled.

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.

Gaskets and seals provided in Wiseco Garage Buddy kits are OEM quality, ensuring your freshly rebuilt engine is properly sealed.

Looks like wiseco is trying to compete against the wrench rabbit kits.  This could be a good thing, but I heard that they’re cranks went to garbage once they started having them built in China.  Anyone have any further truth to that tid bit of info?  If that is the case I’d rather not go with cheap quality material even if it’s so call warrantied because they’re not going to pay when I have to do the work over again when there parts fail.

Ive heard the saying somewhere, “The bitterness of poor quality remains long after the sweetness of low price is forgotten”

We did have some different quality issues going through stages as we developed and progressed our cranks, that's no secret. We have addressed each issue we've run into, including changing parts sources and establishing a new, specific QC process for our cranks. We're continuing to develop our cranks to this day, and more updates will be added to our cranks in the future as well. Here's our R&D and QC process currently: http://blog.wiseco.com/inside-rd-and-quality-control-of-crankshaft-assemblies

We haven't seen as a high of a demand for bottom end rebuilds on those models, but I can check in with the Product Manager to see what the timeline looks like.

Update: The crankshaft is on the list of to-dos, but it would most likely be next year sometime before we see a Garage Buddy kit for it.

Nice to see competition with the wrench rabbit, but this kit (2 stroke) does not supply transmission bearings. Good, 90% of the time transmission bearings in a 2 stroke don’t go bad.  I’ve never come across one of the “so called” bad cranks on any of the strokes I have fully rebuilt. 

Good for you to offer a conditional limited warranty. 

The YZDOC does the same on all rebuilds and restorations, when paid in full.

I assume these kits are rotating assemblies only correct? No valve train components for 4 strokes?

The only valve train components included in the 4-stroke kits are cam chains, but there are no valves/springs, etc. However, keep your eye on us, because you may see something you're looking for coming soon. 😉

Thank you! We were on the same page with the transmission bearings, we figured most people would not need them, so it would be better to keep the price point more affordable for people and not include them. We're glad to hear you've good experiences with the cranks, we've been working hard for that!

      Hey guys,  
      I have a 1969 (approximately) Honda Z50. It was given to me after my uncle died. He would ride it around the dirt lake road between our families houses with a beer in one hand and a cigarette hanging out of the side of his mouth laughing the entire way. If you've ever seen or owned a Z50, they are a little ridiculous. All I wanted when I was younger was to ride his mini bike but I never got the opportunity. After he died, it sat in his garage for a number of years until i eventually came to own it. 
      Unfortunately after sitting for so long, it is not starting at the moment. In addition he was not much of a mechanic so it needs some serious TLC. I thought it would be a great honor to restore it in his name and put it back on those lake roads. 
      I need help guys. I can figure my way out around a bike but I am a little curious where to start with this old hunk. I would be happy to get it running again but I am also looking at possibly engine swapping this little guy (80cc or 125cc) if possible. And I know what you're thinking, "waste of time.. or this idiot has too much time on your hands"......agreed but I think you can agree that would be pretty badass. And for the short amount of time this thing gets used it would be a fun little project for nights at the lake. 

      If you have any advice on where exactly to start or if the engine swap is possible please let me know. Not looking to hear from any of you automatic 'nay-sayers,' have a little imagination and appeal to your younger 12 year old self. 
      Thanks, 
      Chip

      Anyone ever had this happen to them? First practice of the day I got the bike warmed up for 5 or so minutes and pulled off. Second time out the bike locked up in the air over a jump on lap 2. Pulled the motor apart and found second gear in pieces and a lot of other transmission components got chewed up from it. Parts being replaced are: 2nd gear, 2nd pinion gear, 5th gear, shift drum, all 3 shift forks, both shift guides plus all the washers, circlips, and bearings. The bike is a 2011 so should I play it safe and replace the entire transmission since it’s opened and I’m already replacing most of it? I can imagine that both shafts might have been bent slightly and the other gears have the possibility of grenading at any time. 
      Any advice would be appreciated 
      Thanks

      I accidentally bought sae 10w30 oil instead of 2 stroke oil. Is this ok to run?
    • By wachterxc
      Just bought a Husqvarna TX300 and the stock mikuni is giving me the worst gas mileage I have ever experienced on any 2 stroke. There is a little bit of spooge but not enough to seem extremely rich. Also, when I began running out of gas I would shut the gas off and the remaining gas in the bowl seemed to go forever. Perhaps the float if too high?
