New Member Intro/81H Build, Icebreaker

[Arthur_of_Hex]

the light is clear, now I see. Yet......is the xs750 rear same different? I ask because..... Customer is having us build a street/cafe 750. Street equals lower gears. So if a difference, we could give him the 11 rear and I use the 750 rear....if a significant difference that is.....how's that mud Greg?

[BA80]

I don't know the exact numbers but the FD in the 11 is lower geared than the 750 (850 same gearing but has the type II case) but the 750 and 850 are geared lower in the transmission itself.

If you put an 11 FD in a 750 it would be REALLY low geared.

Read HERE what the differences are in the 750/850 FD and the difference between type I and type II.

[Arthur_of_Hex]

I remember reading that info this spring. It seems the 750 swap is in my best interest. Tomorrow morning at the shop I'll measure the ratios on both and assess if the 750 will work with the ratio I find.

[BA80]

The reason I say 850 is that the 850 is the same ratio as the 750 but ALL 850s came with type II FDs. Only some of the 750s came with the type II.

The type II is MUCH easier to deal with.

Hey Matt,

Just to sling a little more mud....does your customer want/need the bike with a lower sitting profile as well? I think the 750s also had an 18" rear, but it's also narrower at 4.00 vs. the XS11 that's a 17 x 4.50. You might be able to put an XS11's 17" or even 16" to further reduce the gearing as well as lower the rear seat height a bit!? JAT However, not sure how much clearance there is with the 750's swingarm and the rear wheel, so not sure IF the rim and tire would fit the 750 without rubbing??

T.C.

BTW, not sure if you're familiar with it, but Yamaha has an online parts fiche site free to use: http://www.yamahamotorsports.com/par....aspx?ls=sport

I'll make sure we get the full wishes from the customer before making drastic changes, I usually use boats.net but I'll check that site as well. Any resource for oem info is good.

Soooooo, it seems the header I found was designed for a non-oil cooled xs. Even though I've been told that I can pull the cooler and be fine, I've always been an advocate for as much cooling as you can have, especially with air/oil cooled bikes. I'll keep the header on the extreme rear burner until I can come up with a filter relocation kit and keep the cooler.



I know it looks like it fits ok. The angle coming out of the head is not right, as well as it hanging WAAAY low underneath rather than being tucked nicely.

I'll polish and clean up the oem pipes for now.

[Arthur_of_Hex]

Headlight arrived from Lithuania. I chose this for 3 reasons, 1 H4 bulb. 2 oem yamaha part, 3 matches the indicator assembly angles nicely.

LED taillight and turns on the way. Also ordered all the powder I'll be using from prismatic. I've decided to tip my hat to classic Kenny Roberts yellow with filmstrip. We have many ideas floating around the shop regarding the overall scheme. I'm definitely interested in any from you all.

Because of the huge engine and no place else to run the pipes that is a problem with the 4 into 1 on these bikes. The 4 into 1 system with the best clearance on the 11 was the Kirker. It used smaller diameter pipes but still scraped on speed bumps and such.

Kirker systems are getting really rare though.

[BA80]

Here's a pic of my bike when I first got it with the Kirker on it. Even tucked up that tight the bottom of the pipes were flattened.

I hated it because every time I changed the oil I had to remove the exhaust to get to the filter. And, no center stand.

[James England]

The best 4 into 1 I ever had on an XS1100 was a Sebring. I bought it new. It was so well made and tight to the engine that the ground clearance was excellent. Also, the gold can (which looked quite radical at that time) sounded excellent. The headers were factory-painted in black and never degraded, even at the tops. Negative was that the centre stand had to be removed but, even then, it wasn't that much of a loss.

I saw the same Sebring system for sale on eBay Germany a few weeks ago.... It went for around $200.

Found a pic

Here's one....

[Arthur_of_Hex]

So...many projects later at the shop and I'm now knee deep into the 11. Got the engine placed on a stand.

Pulled completely apart and every fastener labeled for ease of reassembly.


Started powder coating the engine with "ink black" from prismatic.


Experimented with my sanity trying some fancy powder work on the end covers.

[Arthur_of_Hex]

Now, I'm not sure what degree of bludgeoning this will earn me but...my 11 front master cylinder was in very bad shape, I decided not to use it, the reservoir was sun baked to leakage through the cracks. In the shop discard box was a very serviceable seca 750 hidden master cylinder as well as right hand cable control to match! I like mechanical gadgetry so I've rebuilt the cylinder and ready to adapt the control to the 11. Giving me the same 11/16 front brake master, as well as a cleaner handlebar look with cables only up top.

You have piqued my interest with the hidden cylinder
