88 vs 92 motor??
I am wondering what the differences are between the 88 and 92 motors? I know about the rear bushing issue, as I am going to use the motor for an aluminum frame project. The reason I ask is that I have a guy who wants my 92 chassis to put the motor out of his 88 in. I am getting a new pipe anyways for the project. So I thought why not have him just throw in some money and swap him bikes if his motor runs decent?? what do you think, am I making a mistake here? Then I can sell some parts off the 88 and come out really good? give me some opinions and wisdom oh wise hoons..

Hey but what do I know, just my opinion!
92 still has the close ratio trans. But everything else is current.
The CR500 is an acquired taste. If you don't like it, acquire some taste...

85-89 has the early narrow model clutch basket and in 90 they switched to the new aluminum clutch side case with the water outlets next to each other, where as the early model has the rear one pointed back and upward towards the back of the cylinder. That is because the pre 89's have the cylinder water inlet above the reed cage and the newer on the right side of the cylinder, and the pre 89's have a slightly longer reed area.
Look thru this post, lots of pics to better help explain.

If the basket is good in the 88, why would you replace it? With the magura on my 85 and my friends 99 (also magura) I cannot tell a bit of difference.
You guys overthink this thing way too much. A friend of mine who is an A rider raced an 85 and an 86 when they were brand new....he says they were great bikes. He did remember that the 85 had more power and that the water pump started leaking almost immediately. The 85 3 cog tranny didn't blow up. He said the clutch was fine on both bikes.
With the old clutch cover the only extra work is having to remove the kicker and the pipe to change the clutch. Big deal.
All of the cr500 motors were good engines. Replace any worn stuff on them and they will give you good service.
I might worry about it the clutch or tranny if I was going to put the bike on the bottle, or dirt track the thing and bang the same gear every time around the track, but for 95% of us it doesn't make a difference.

dude, I was riding my gen-4 with the '90 motor around the neighborhood over the weekend, and that close ratio sucks ass! I was pinned in 5th on 14/48 gears and my eyes weren't even tearing upAlisoBob wrote:If you ride Dez, the close ratio tranny really sucks.
my gen-1 with the '86 motor in 5th on 14/47 gears made me look like the guys from dumb and dumber when the made it to aspen on the mini bike!
the trans ratios make a big difference.
I'd stick with the '92 motor. the extra clutch disc, and more importantly, the throw out bearing make the clutch action much smoother in a '90+. You won't have any host/pipe interference issues, no crappy thick head gasket, has the right kicker on it.

the older ones were a harder pull because of tighter springs to compensate for the lack of friction surface area, and the shitty ball/socket style throw out bearing.nmdesertrider wrote:I love you bro but I doubt you could tell the difference between the two clutches if you didn't know what was inside.
even if you don't notice any of this in the action... you WILL notice the wear difference.

Edit : danny beat me to it
The newer clutches definatly have a lighter pull, because of the extra plate they have lighter springs and that coupled with the throw out bearing does make a diff.
I have the old school setup in both bikes and with the barnett carbon + heavy springs in the nitrous one clutch pull armpump comes quick

brit has one on one of his bikes, didn't seem to make the pull any easier to me.nmdesertrider wrote:With the money you save you can get a hydraulic clutch which is better than either stock setup.
Now, I don't mind a hard clutch pull, so I put '86 springs on my'90+ clutch to make it really stiff... eliminates slip. My terror of a gen-1 has been running the same clutch for 2 years and last time I had it apart, it looked like new... and EBC too.

LOVE my Magura!
I don't know what you boys are talking about "no feeling"... I think it has MUCH finer control myself.
It's like using a needlenose to remove a master link clip instead of a pipe wrench.

No longer have a CR500.

Thanks for all of the response guys. I took your advice and just sold the chassis alone. The motor that was in my 92 is super clean and smooth. So there was no reason to take a shot on a different motor. Now all I need is some parts from Shan (in the mail I assume ) and I will be putting together my second gen 1. Thanks again for the help
