The search for an engine... Opinions please
The search for an engine... Opinions please
After looking at way too many beat or just unknown engines, I have decided that I am just going to look for a complete CR500 to buy for my donor. I have a pristine 2008 CRF250 sitting in the garage waiting to get torn apart, so its time I get a 500 and get this project started.
I was hoping to get the newest engine I could, but I think Im headed in the direction of just getting the cleanest complete bike. This way Ill at least get to fire it up and ride it before laying out money on someone's roached engine.
I have done a lot of searches on engines and have seen multiple threads on old style and new style cases/cyl etc... but is there any year that really stands out? What do most guys look for? 91 and up??
Thanks to Danny and Bob for all of the suggestions, I am going to do the conversion based off Bob's Gen 4..

cool. thats what i been saying since day one. foolish to buy a motor that cant be started, riden, shifted... from a unknown source. 9 out 10 times a complete bike is way better deal also. stoufers engine might be good. was saying alot of craigslist/ebay stuff is junk.

Re: The search for an engine... Opinions please
Throw in the shoddy packing and buying a loose engine is even more of a gamble. My spare 87' engine was shipped with the shifter still attached which went through the ignition cover. If I was looking again, it would be hard to pass up that fresh, complete engine for $3,000. Honda put it together, it's the newest you can get and it's ready to go.100hp honda wrote:AMA714 wrote:After looking at way too many beat or just unknown engines, I have decided that I am just going to look for a complete CR500 to buy for my donor.

On my way to look at a clean 1990. I have not ridden a 500 since 1987 when I ice raced an 86 CR 500 up in Canada. Looking forward to it.
I have heard a lot of you mention that if the thing has too much vibration in the steelie chassis that it is probably crank related. I hope I can feel that--lol Any other suggestions or things I should look out for on the 500?

No need to take the bike for a spin. When I get there they are dragging it down the street trying to get it going... I smile, say hi and tell them to stick it. Bike was clapped, cleaned up nice but underneath the new plastic it was rough..... NEXT

that requires a new case, its magnesium and the waterpump will be rotten, 140$ i think, also the rear bushing is smaller than 89 and would need to be machined, outlet on the cylinder is different and its a longer reed housing which can contact some of the 89+ style pipes

I think around $140 is correct. Getting the bushings bored isn't a big deal.Roostius_Maximus wrote:that requires a new case, its magnesium and the waterpump will be rotten, 140$ i think, also the rear bushing is smaller than 89 and would need to be machined, outlet on the cylinder is different and its a longer reed housing which can contact some of the 89+ style pipes

i only ever tried the pc, but the best way would to get both and decide for yourself, i wish i did, cause now i need to get both cause my pc is completly mangled
the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.
