That's awesome!
What's the maitenence like on a CR500 motor? How long between top end / bottom end rebuilds? I hear you need to be more careful about warmup and it has a funky powerband, that true? Awesome. Engine swap sounds like a perfect next project for me. ^_^ You're inspirational! |

Well, I know of some people that have had their CR500s for 10+ years ride them nearly every weekend and never rebuilt a top end. So I guess this all depends on your maintenance and how badly you rag on the thing. Top ends can be rebuilt in 2 hours or less and even if you replace the piston it can be done for $100 to $200 (depends on where you shop and forged vs cast pistons) As far as mileage, I dunno, depends on how you gear it and how hard you ride it, what kind of oil you use, etc etc etc. We'll see! Warmup on these bikes isnt so bad, they warm up real quick, in fact they tend to run a little hot anyways. The powerband is extremely PEAKY. You will suddenly SPIKE in HP at VERY LOW RPMs. If you're not careful you end up sitting on your ass with a front fender in your mouth! All because you turned 1/4 throttle, lol. |

That's awesome. Talk about peaky!
Aluminum frame, 17" wheels, 70hp, yet about the same weight as my bike. o.o I'm so jealous. |

Some people wanted to see a good comparison between SV650 and CR500 power curves. I overlapped 2 plain vanilla dyno charts of each here:

Thank you sir, that's pretty nifty.
Mind if I ask how you chose this particular engine? |

I'd be willing to believe that if it was a hemi he got for only a few hundred dollars with historical significance.
Nicely played though. o.o |

I started to look at dirt bike engines. I wanted something with parts readily available, something with a record of being reliable, and something BIG AND POWERFUL with a history of hurting people. So the CR500 was a natural choice. I've also noticed that people are putting CR500 engines into all sorts of things. Karts, AF CR250 chassis, ATCs ATV, you name it. But no street bikes! Then one day while I was doing some research I came across someone else with the same idea, he was putting one into a korean United Motors bike. He did have lots of problems, but he was doing silly things like drilling carb parts to *fix* things. Bad news. I also looked at KX500 engines, but they seemed a little more complex with the exhaust power valves, and there aren't as many of those around and are much more expensive to rebuild. 2-stroke single-cylinder engines are narrow, so I needed to find a narrow sports bike chassis. I4 bike frames are WAAAAAAAAY too big! But the CHEAP V-twin SV with a blown engine was the perfect choice! They've been around 10 years, has a long list of aftermarket support, its lightweight aluminum and is a rather all-round popular bike that is easy to upgrade. But I have a big box of all sorts of parts, master cylinders, grips, wires, chains, shocks, swingarms, brake/clutch levers and cables etc etc. I haven't had to buy hardly anything yet because I've been diving into my own parts bins and making things work! |

Re: Honzuki SVCR500S - Update #6
Put the engine up on the bench today to remove the kickstarter shaft for lengthening by my local friendly machine shop!
First I drained the oil. I should have done this while the engine was still mounted it would have been MUCH easier! I just kinda forgot. The oil was very sticky and yucky. This bike hadn't been run in a long time, thats a fact! I had problems with the clutch dragging, so while I was in there I checked it all out. The sticky oil was gumming up the discs and plates. Even without the pressure plate and springs installed the clutch STILL dragged every bit as badly as with. I examined and cleaned each disc and plate and reassembled. The clutch looks good with very mininmal wear. The bolts and such don't even have any evidence that they ever had a tool put on them. I was told this engine hadn't run in years, has very low hours, and was never opened up... Now I believe it! Clutch bastket: Clutch plates/discs: And lasty I removed the kickstarter shaft, cleaned it up so I can put it in my pocket to take to the machine shop on the way to work on Monday. Skeeter watched: |

Its already supercharged!
Thats what the expansion chamber is for. Conventional super(or turbo)chargers don't work well on a 2-stroke as they just blow the excess pressure out of the exhaust port. Quote:

I'd rather kick start a 2 stroke than a 4 stroke any day, though I have heard those 500cc two strokes can be tricky to start.

thought so. Iv'e heard about people hurting themselves on rs250's so if you slip on that 500cc kick, mmmm...! but its sure worth it, when you think of the power and weight saving!

I've heard of CR500s firing halfway through the kick stroke while a little skinny sh!t had all of their weight on the kicker and got launched into the air over the bike, lol.

Not nearly as many riding years here, but the Ninjette is also my first bike without a kicker. took a while getting used to. Also the bike I learned to roll-start, because of the 'missing' part...

Well I'll be doggy dicked, I never thought you to be that matured. I figured myself to be one of the older guys on here, and I only started riding in the very early 80s, lol.

Man thats going to be some fun! At least if you get tierd of kicking you can push start it. I have 3 87 quadzilla 500's (little disapointed you didnt go with a suz 500 but understand a deal on something is a deal) When we go riding with my quads like with my wife and others that can't kick over a 500 I have to kick all 3 and let me tell you 1 is stock and the other 2 have high comp pistons and by the time I'm done starting 3 cold 500's ....I'm to dam tierd to ride! LOL
Cant wait to see this thing running!

I did consider finding a quadzilla engine, but there seems to be less aftermarket and OEM parts support. I also couldn't find one for the life of me! They stopped making those things almost 20 years ago! A more recent CR500 engine with much more information on the internet about it and parts availability made a better choice. Besides, now I can call it a Honzuki and have people's heads turn. |

They did a good job on that starter shaft. It looks factory. Have you fabricated a supported for it yet?
