86 big bore interchange ability

[Atcrider1]

Will the clutch basket from an xc 500 fit on a 400 or 430 and will a flywheel from from a 400 or 500 fit on a 430 ?

clutch baskets can interchange, remember to use the matching parts, the crank gear and the kick starter gears
when you say flywheel I guess you mean crankshaft, 400 and 430 are the same 500 is a different issue not the same

Generally I have always found the 500 clutch basket's aluminum fingers to be solid blocks of aluminum where the 430 has been sort of like a channel (think structural steel shape).There is a lot of variation in primary gearing and then the 87-88 set up the basket is steel for sure and pretty sure one piece with the primary gear.

Do you need a link to a parts sheet to study? Even the smaller bikes look the same but the basket gets dwarfed more by the bigger gear it is attached to. While it may not be exactly the same I have a 125 engine in a box and that clutch and primary gear looks a lot like the one that matches with the 39 tooth engine gear on most 500 and some 430 but the smaller crank size and smaller crank gear make it work out.

I am guessing flywheel means ignition rotor. You ask questions that really need a lot of typing as there are a lot of variations but I think the taper and the key location are the same on all of those but other stuff might need swapped besides the ignition rotor.

edit: I now noticy you specify 1986 in the title but doubt they made both a 430 and a 400 with clutch parts discussed in the same year so I kind of have to assume this is a general across the years type of thing.

I have a 430 crank in a 400 wr crankcase with the 400 wr trans was just wondering if the flywheels were the same for the 400,430, and 500. My motor already has the 400 wr external rotor ignition stator on it just need a flywheel and all the400 and430 flywheels ive found on ebay are expensive

T The stuff from 1985 on has much more detail like the type of ignition.​

​

The motoplat mini 6 is most likely the external rotor ignition lighting coil set up for the stator you have. If you go to the above pdf file you can see the sem is mostly in the 250. The mini 6 has one yellow wire, others have two yellow wires and others have more wires still one for headlight one for tail light one for little bulb in speedo but I don't think that one was used in 1986. The rotor should be surplus (or sold with the stator and coil) as what can go bad except it get loose more likely the stator goes bad I would expect as there are folks who re wind them.​

​

Though things change over the years the 400,430, and 500 cases are the same (In a given year). The 400 and 430 (non auto) crankshafts are the same. In 400, 430, and 500 wr and xc transmissions have the same shafts and gears. Even some of the 250 transmissions share the higher gears and some six speed cr transmissions seem the same. As does some of the four stroke older single cam cagiva owned transmissions.​

there is a slight problem with that, the Motoplat ignitions were built as a unit and serial numbered as such, after they were built the timing was set and a hole was drilled to index it for future timing
if not matched units timing is a crap shoot, watch out for the lead cover color too
all Motoplats 250 400 430 500 are timed the same and can be used in any cc
don't forget to lap the rotor to the crank

So what you are telling me is i have to buy a stator and a rotor as a set? I have a stator already jus needing a flywheel,what do you mean by lapping the rotor to the crank?

 

[fran...k.]

I think what that means is that upon mixing and matching rotors and stators it would be advisable to use a timing light and find top center and mark off how advanced you want to go, to get an idea if when lining up the holes it is exactly as desired. By lapping one would remove the key, apply valve grinding compound or similar substance and twist back and forth with pressure until the grinding marks indicate contact is being made everywhere. That part is in the owners manual if you switch rotors.
