I just got some slingshot 38's?

[thebrandonbeezy]

Yeah, ill keep them for something else later on. Find somthing more suitable for the old 8 valve

The sliders are ceramic and short of a hammer do not wear. The inserts are usually wear as they are no match for the slides. The insert wear starts the emulsion tubes to wear and it is all downhill from there.

Minimum to rebuild is new inserts and new emulsion tubes with new needles, and of course proper jets for your application, which for a 8V 1000g is not even applicable as they are too big.

Been told that the 36mm carbs you cant buy the inserts, so maybe the 38's are in the same boat. You can always get them made i suppose. Mite be easier to just go and buy a 1100GK with the D shape heads and sort that out .........

I am in process right now of redoing the top end of my 78 Gs1000"Roadkill"
I have a set of 1100 cylinders (stock bore 8000 mile block) , installing new rings ,
Yousimura cam set ( don't remember the lift)
83 GK d port head with new valves ,seats , and guides , springs
and a set of CV 36 mm carbs from stock 1150.
Going to try and use stock type air box but if I can' t I will be designing something that will work and let it breath.
I love having access to a dyno to help figure these things out
The exhaust is a custom free flowing 2 into 2 2"" exhaust. Not sure how all this is going to play out but I will be able to tell you when it is done

I definitely want to do a 2 to 2 next time with stubby little bullet mufflers mmmmm hahaha
But your set up is basically what i will most likely end up doing

The36's are available; Chef1366 has a source
I think 38 slides are the same but don't quote me.

[thebrandonbeezy]

Would 36 sling shots offer better performance than the 1150 36 mm?

Yes if the motor can handle it. like BB 1100

Chef1366 has set-up 2 sets of slingshots for me and both have turned out great. The wear points that Posplayr mentions have to be addressed as EVERY set I have seen has been wore out. Not sure about the spacing on a 2 valve motor though. I do know the spacing on a 2v 1100 is the same as a 4v 1100 as the carb bodies are the same with different internals. Slingshots work fantastic on a 4v motor.

If you get a DJ kit for those, they will come with new emulsion tubes... like everyone else has already mentioned, they are the first things that wear out and they will make the carbs run rich and impossible to tune. However, I'll bet any DJ kit you get would be waaaaay off for your needs as they are designed for bikes with more cc's that turn 10,000+ and make 140+ hp . Also, don't try to mix and match the DJ tubes with the factory needles as they are usually set up with a different internal diameter to match up with their needles. I think Factory Pro sells the emulsion tubes separately and they are factory diameter.

The 36mm Slingshots work very well on my mostly stock 1100... the throttle response is much better than the stock carbs, but I spent a bunch of time with the wideband o2 meter to get it set up right.

that exhaust

[sharpy]

Arent X pipes a gimmick? And those 2 into 2, you mean a muffler exiting each side? They sound like there running on 3 cylinders if you havent a cross over tube. Or you mean 4 into 2 into 1 setup? Im playing around with Cad atm trying to see what pipes i can make. Most of that is from memory. Need to measure more to set up the height and length better.

Not sure how to post an old thread on here, but you can search "roadkill' in the search bar and then look for thread ' It has begun' that is my Roadkill build thread, it will show you the exhaust

The slingshot carbs are updated but the air screws are under the barrel, I have a hard time adjusting them with engine running. The GS carbs have the air screws on top of the barrel and are easier to adjust.

So i just found out that the 89 to 93 katana 1100 had bst34ss carbs, im considering this as i may buy one with a bent frame for parts
