There is a hinson clutch basket available @ dennis kirk and I saw one on ebay earlier,That thought of changing to the newer side cover and clutch is already in my mind,I wouldn't even mind buying a complete engine right now if the price was right.dannygraves wrote:of coarse if you have the green I would recommend doing what I did. Not only is the clutch pull a lot lighter, but the operation is smoother. Most importantly the parts are available. I couldn't find the center and I wanted to replace my corroded waterpump anyway. I bought all the parts to do the conversion used from a guy parting out a '93 for like $100+shipping. Now if I break something I can find it easily. If I notch up this basket I can go buy a hindson which I couldn't do with the old one.
you have to remember that IF you do buy a whole motor and it is newer than '88 the swingarm bolt holes will be 2mm larger and you headstay won't fit and you will have to use the carb boot from the old motor.kkvslayer wrote:There is a hinson clutch basket available @ dennis kirk and I saw one on ebay earlier,That thought of changing to the newer side cover and clutch is already in my mind,I wouldn't even mind buying a complete engine right now if the price was right.dannygraves wrote:of coarse if you have the green I would recommend doing what I did.

Your right its a 86dannygraves wrote:'87 is everyones fav year. great power like the older ones, but it uses the new rod and the newer ignition and still has a wide ratio trans ('88 went close ratio). But it still uses the old clutch and the old countershaft so the c/s sprockets are still a little harder to find.
What year is your bike anyway? for some reason I want to think its an '86.
if it is '86 or older and you find that you need to rebuild the crank you may have to get an '87+ rod kit and put a spacer under the cylinder.
I wouldn't be surprised, most of the parts that are pre '87 are unavailable, or it will say that it is, but they just send you the newer vesion which doesn't fit. I've heard of people buying the old clutch basket from SH and receiving the new one.kkvslayer wrote:I'm looking @ a parts fiche and it says the mainshaft fifth gear is N/A,is this true?
How much does it cost for a resleeve,new piston kit?AlisoBob wrote:Good call Mike.... notice the reveal on the combustion chamber too.97af wrote:Maybe its the picture but that cylinder sleeve looks really thin.
2MM over maybe?
KKV, I know your in the middle of "Nowheresville"....
How close is the nearest machine shop?
( or UPS depot?...... )
so you guys think my piston is too big or too small for the bore?AlisoBob wrote:Like any journey, you need to know where your starting from....
Thats why I asked you if a machine shop is near by...
It could be as simple as:
1. Have bore measured, and find out its within spec.
2. Have head opened up to match bore oversize.
3. Order piston kit of the proper size ( the whole kit should be about $150)
Reassemble.
OR, your may find that the bore is junk, and you are at the last oversize. A new jug from S/H is about $260 last time I checked...
OR, you may find yourself somewhere in the middle....
Measuring the bore is the first step in any scenario....
Resleaving , in my opinion, is a poor option. ^o with the new jug. Its like $20 more when all is said and done.
If my bore was Too small wouldn't it have seized or have more scuff marks or if it was to big wouldn't there be more blowby because it looks very clean with a few scratches and the one little scuff thats showing in the pic.AlisoBob wrote:I have no idea... this is what YOU need to find out.
Once you find out about your "Bore Size", you can proceed in the correct direction.
