I was told they would work, but thought I'd check here first I'm sorry, but I'm not sure what a downdraught carb is? What differs from other carbs? Looked normal to me, but I'm only used to twosmokes

Hi! Got a good offer on some 38mm mikuni roundslide vacuum carbs from a Yamaha FZR(i think)1000 today. ~£100 and they come from a bike who has only went about 20k miles no need for rebuild yet, right? There wouldn't be any problems using those on my '86 1100EF? Except maybe having to modify the intake? Also, what size are the original ones? Haven't got the bike home yet, so can't check...

Thanks for the information! That's a store I didn't know about, far more reasonable price than cmnsl and the other sites claiming ~£140 for just the pump gear Reckon it will be much cheaper for me to have my mate make it. If I remember correctly, he made a lot of the gearbox gears for at least one of his twostroke beasts (132rwhp RG500 and a yamaha RD500). I'll definately run it past him to sell these gears!

Doesn't look like that I have a mate who can do some cnc machining wizardry, I know he has made own custom gears before, so I could turn to him if this gets difficult

did some research, 1977-83 gs750 oil pump gear (part no 16331-45000) looks just like the gsx1100 oil pump gear, but has 29 teeths in stead of the 1100's 33 tooth expensive though, 150$ for a god damn sprocket couldn't find it in the Schnitz racing online shop?

I don't think I'm gonna turbocharge it, but noone knows what the future will bring thanks for the input anyway What year GSX750ET do you use oil pump gear from? 1980? Is this forum new? Didn't know Two more questions: I want to get upgraded cams, new exhaust, and maybe new ignition coils if the old ones are bad. What size carbs is appropriate for those modifications? And If I run this setup, what do I have to do to the oil system? Gsx750et oil pump gear and the top end oil feed kit?

Thank you so much for the good answers, guys! I'm determined to build this bike the way I want it, and it's going to be a long-term project. I don't care if I blow the budget, that just means I'll have to wait a bit longer to get it on the road.

Hi! Hope this post is placed right, I'm new to this forum. I am soon to be the owner of a mid-80s GSX1100EF, it's in need of som love so I am gonna do a total rebuild. I'm just doing a little research on these bikes, and I discovered this site: http://www.suzukicycles.org/GSX-series/GSX1100EF.shtml, it says the '84 model has 114hp, and '85 and on has 124hp, what is the differences here? I'm not sure what year the bike I'm getting is, it was said either '84 or '86 mod. The bike uses some oil and theres a little blue smoke in the exhaust. Current owner reckoned it to be the valve stems, so I have to do some work to the engine aswell. I want some more power out of it, I have the equipment for machining the cylinderhead, and I've looked at performance cams. But I see there are gsxr1100 cylinder heads on Eblag for much less than new cams etc. Would I be better off just buying a gsxr1100 head? The EF is 1135cc and gsxr is 1052cc, does that mean it won't fit? Also, since I am rebuilding the engine, or at least the cylinderhead, what parts would be wise to change in addition to prings and stems? The camchain for instance?
