Bst36ss carbs 1200 motor tune

GSX1000E - I have always pulled the carbs to make adjustments in the past, so that was the plan here. Ideally there would be room to plan for all of this, but unfortunately the nitrous kit takes up a lot of real estate on a frame that is already limited in this area. The boots and flanges are on the correct cylinder ports. The intake manifolds are from the stock bandit 1200.
 
Just LOOK at what your float level would need to be at for those carbs to work at all. Until you get those carbs closer to level with the ground...
 
Ah ****, I see exactly what you're saying now. I'm surprised this wasn't discovered earlier in the thread. That's probably the whole problem with the idle also. The bowls aren't filling correctly. Damn, there probably isn't going to be an easy way to fix this. Might have to remake the motor mounts.
 
Looking at Bandits though, there isn't a whole lot of difference in angle. It actually looks very minor. Take this one for example: bbike.jpg

I'll go through and make sure the Boots are on the correct cylinder ports. It's been a while since i've looked at this. I may have to find a creative way of re-routing the nitrous and fuel lines. Do they make some kind of boot that has a 45 degree angle that would make these sit flatter?

Look back at post #31. Those are not stock GS 2-valve intake manifolds BTW. Notice the float bowl orientation. ;)
 
Yeah I see that. I need to somehow find flanges with a 35degree turn down.

And what happens when you switch 2 & 3 and 1 & 4 manifolds?

Are you telling me to try this first? Worst case scenario, I'll scrap the stock ones and the nitrous flanges, buy some steel stock, make flanges, and weld 35 degree tube turn downs, drill/thread holes in them for the fuel and nitrous delivery, then get rubber boots to attach them to the carbs. That feels like the right thing to do anyway.

A long time back guys were using radiator hose for intakes..... short sections.
 
i hated these carbs on the GSXR's and bandits..
on the other hand the 88-93 kat 1100 carbs and the 86-88 GSXR 1100 carbs are very user friendly.
the above carbs require the same jet kit by the way...34mm vacuum flat slides.
 
Is it safe to say that at the angle my carbs are at that the bike would be able to idle, but would stall when opening the throttle at all?
 
Short metal tops 34mm taller plastic tops 36mm some Canadian models got 38mm and wasn't there some 40mm?? This is my experience with them I could be wrong. If it idles but dies with any throttle sounds like too lean try it with a little choke pull. I'd say it has a massive air/vacuum leak or needles too low. ???
