Billet 250R clutch baskets question

[Dammit!]

I know the Hinson billet clutch baskets require a minor modification to install on a 250R. Something about grinding or beveling the gear on the crankshaft if I remember right. My question is, are there any billet clutch baskets out there that drop right in with no mods needed?

The mod needed for the Hinson is minor and not that big a deal but, if I can find a drop in part for close to the same price, that's kind of a no brainer.

i instaled a wiseco basket in an R A a few years ago and it needed no mods

[Dammit!]

What year R was it?

If you install a Hinson basket, you need to use the 89 only TRX crankshaft drive gear. Its narrower then the earlier models, the wider ones will drag and rub on the edge of the basket if you try and use them.

What year R was it?

86 trx .......

would a shim fix that? There are a couple on the clutch pack, arent they?

I put them on 85 and 86 motor with no mods. You need a grinder to grind down the rivets in the stock basket, how much harder will it be to grind a small bevel in the gear???? I never grinded a bevel, nor did the shop I used to use. He did 2 baskets for me, no case damage.

Mine didn't suffer any case damage but the inside edge of the basket where it hooks onto the back gear clearly rubbed the crank gear until I bought the newer 89 gear.

I have a pic of this same problem right now 85 250r engine on the bench.Hang on......
Ok in the first pic,you can see the scalloping of the basket.This is a aftermarket basket from a 85 250 R.The basket was made to fit later TRX 250r's
In the second pic,you can see that he ground down(or beveled) his primary gear to clear,but it was not enough.
However it was close and after running it awhile,the interferrence(sp) stoped.He will be fine now.
I do suggest doing what others have said and go with the later primary gear from the quads to avoid this.
He is not having issues anymore,I just posted thes pics for your reference.,I will call you this weekend.Been busy lately.Sorry.

[Billy Golightly]

Yup Rob thats pretty much exactly how mine looked.

[Dammit!]

I've never taken the tranny apart before. How much of a PITA is it to replace that gear?

Gotta weigh the savings of the cheaper basket against the added expense of the new gear and see if it's worth the trouble over just buying a Wiseco basket or something that needs no mods.

[tecat-z]

Tranny doesn't have to come apart. Only clutch cover removed.

[TeamGeek6]

Two things:

1.) that engine in the second picture is seriously dirty inside, looks like major sludge inside.

2.) with any chance of metal to metal rubbing, put a magnet inside to catch the shavings, theyll wreck ball bearings in a hurry.

[Dammit!]

I just looked at my spare bottom end so I see where that gear is now. NM the previous stupid question.

Edit: If I'm looking at the right gear on service honda, the 1989 gear is not available. Anybody know if 13615-HB9-770 is the right number?

[Dammit!]

Is the Hinson the only one of the billet clutch baskets that has this problem?
