The 36s that are on biker's 790cc 2002 BA have no hesitation whatsoever. You whack, you fly. at any throttle position or RPM.
Last time I looked at his carbs, it appears they are ready for pumps already, there is capped off spot that could be reomved and insert a pump assembly,
I believe this is what it is for but I am not 100% certain. Some future research will be in line for that when the time comes.
The HS carbs are also about twice as much money by the way than the TMs.
I agree 100% that the 42 pumpers are too big, been there done that. I had some but could never get them dialed down lean enough to work properly. They were real monsters though and really improved the response. I had about 65.5 hp with them and Tbike pipes when I was playing and dyno'd them. But they just kept machine gunning from the flooding whenever I hit WOT for more than about 5 seconds. They are now available with much smaller jets and needles and I have read where they are now working quite nicely, but they are about $1600+US.
Ed's (biker) bike runs really strong and we are going to get it on a dyno soone to see what is actually going on with them too. He also had to jet and needle his down to work with the 790 motor. The good part about them is that you can get mikuni jets/needles in tons of sizes and they are readily available from almost any motorcycle shop. I am certain they are even plenty beefy enough for the 904s, like several of us already run.
I should have mine in next week hopefully and will keep everyone posted. that was the whole deal with Jane agreeing (sorta) of getting them. I told her I would recoup my money by selling them to youz guys. So, in a way, you guys will pay for my R&D work.
One issue I still have to work out is the main throttle cable. At present we had to take the stock cable and cut it and adapt it to fit the two into one cable that lift the slides in the new carbs. Not a biggie though. I have a source to buy all the goodies to make up cables too. And after playing with the Anals (

) I have gotten pretty good at making cables by now.
Another minor issue to some, may be that you willl end up with two seperate choke knobs. You need to sorta reach in and choke them individually, then remember to shut them down after a few miles. There are some two into one choke assemblies, but after my experiences with this sort of setup before, I prefer the individual chokes. But I'll see whare that leads later as well.
