Thank you Joseph, I found a set of BAPP ones but I may go with your find because they are a little bit cheaper than the BAPP set.

I have some !

**1979atc** · 02-16-2016, 09:07 AM

The bolt set will be used on the motor that has the polished cases. I'm still gathering parts for it. I will be using plastic fenders that are in really nice condition no cracks. I have a tank but it needs redone. So I will be using my tank off of my 77 90 for now. Pm sent to you Jwheeler.

I have some more parts coming and I got this modification started today. Yesterday my stage 1 cam arrived, and I have a sl 90 counter shaft coming. What you guys think of the case?

Looks good to me. I have a case that I cut down like that. I just need to find the right cylinder so I can get mine put together.

Looks Good. All you need to do is just a little finishing on it and you'll be good to go. You can fill the holes with two part expoxy. I use a belt sander to smooth everything up.
I am the master at removing the Hi/Low gear box. lol

Another thing you will need a different seal for the SL counter shaft. The one for the Hi/Lo will not work. I think the correct seal is the same one used in a CR250 IIRC.

I think this is the one you need.

Ok thanks for the information Joseph, I will get one coming.

**1979atc** · 02-25-2016, 12:13 PM

My counter shaft and case bolts came today. Is this the right shaft? And it has 23 teeth on the gear. Thanks

I did some test fitting to see if the shaft and everything worked. It did, now I'm waiting on my counter shaft seal for the sl90 shaft. And then the bottom end will be ready to got together. Had some bearings for my crank and transmission shafts so I'm all good to go. My piston rings should be coming here sometime. Then I need to get new wrist pin clips then we're all good.

**Joseph Farrow** · 02-25-2016, 09:46 PM

Shaft looks right. Just transfer all the gears from the standard 90/110 with hi/lo over to the sl shaft.
Pick up a clip from the local hardware store to hold the sprocket on and you'll be good to go.

**1979atc** · 02-25-2016, 09:50 PM

Do you think I should get other sprockets? I have one and it's a 11 tooth. I have a clip set should have one that works, and swapped gears to sl shaft and everything worked out. I will be putting bottom end together when my shaft seal comes. Thanks for the help.

**Joseph Farrow** · 02-26-2016, 10:13 AM

I am pretty sure you can install the seal from the out side if you want to go ahead and put your cases together.
Also the front sprocket all depends on your rear sprocket rear tire size and engine mods. A good middle of the road front is a 13-14 tooth. Smaller the front equals more low end bigger the front equals more top.

**1979atc** · 02-26-2016, 01:02 PM

Ok thanks I will see if I have other sprockets somewhere. Today must be my lucky day, my seal and my rings came today, only thing I need is a shifter shaft seal. Turned out that one was bad and those are common to leak when worn. I will be ordering one of those. But I can still put the bottom end together, I need a head and I have a 90 motor that needs a lot of work, could I use the head off of it?? I plan on porting it anyway I just didn't know if they were the same as a 110 or not. Thanks

81-84 250r sprocket seal works perfect as well
