Whats the general consensus on bike carb'd xe's?
Have the chance of some Kawasaki 1100 carbs, management, fuel pump, dizzy, coil, carbs have been jetted for c20xe and rebuilt, then painted.
Just need inlet manifold, air filter & set up.
Worth the hassle?
Is Bogg Bros only place for manifold? Would it be worthwhile making my own? Have the base plate with the carbs, would just need some pipes to go from plate to carbs measured & made up.
Ideas please

They're usually only 40mm diameter, that's a bit narrow for a 2.0 engine really. People will probably say I'm wrong, but you'd get the same response from people if you were going to put on some Webber twin 40's...
Saying that, you can get a good power hike using them, especially if you have the right cams and jets fitted.
Bogg Bros. will do you an inlet and jet them out correctly for them engine though. You just need to tell them the spec of your engine for them to work best.

manifold from bogg bros cost me £215 delivered.
I havent driven mine yet, but the bike carbs are supposed to be lower maintainance and have a slightly higher power increase than the webers/dellorto's of the same size. Plus they have better throttle response.
The jets should be 1.8mm for the xe and you'll be just fine!

Aye, engine is ok, got rebuild, 2.0 16v, ported & polished head, xev inlet, piper 270 cams, verniers, sbd type A manifold, 2.25" system, lightweight pully, f20 box, with f18w final drive.
So, should be a healthy engine when its going (in paint shop at moment)(still).

hmm...well the engine may not run at full pelt wit those carbs, but, like mine it wont be stressed and wil run comfortable power.
My C20SEH was RR'd at 174bhp @ wheels on injection. I reckon it'll run just under that on carbs but thats still enough atm tbh.
(I have R1 carbs btw)

should be an improvment over the std injection though i guess?
Whats a good price for the kit that i've listed?

£200 is a good price. but £250 is probably about their true worth. if you can get em for £200 you've done well

just need a manifold, think making one will be best, as 215 quid for a manifold is a bit loopy.
then need filter & set up

aye...well i think pipercross actually sell a filter set up for those carbs (unlike mine wher i have to cut the filter base plate)...
If you can make a manifold that'll sure save you a load of money

kit comes with the base plate for the manifold, so just need the pipework, which i can make to the exact size i want, then just need some adapters knocked up for the carbs to fit on.
Don't know what to do, if its worth the hassle or not.

I'm not 100% certain but think AndyW had bike carbs on his red top.
If I remember correctly it was very tractable, drove nicely, sounded great and made good power.

you also need a filterking regulator about £45 from bogg bros
and a low pressure fuel pump
a single outlet header tank
and either a breather filter or oil catch tank
and different ht leads as the normal ones dont fit the dizzy
i have gsxr 1100 carbs on mine with bogg bros manifold and the quality is mint mate do it proper and get a bogg bros one they sound awesome when on full throttle
and just to point out that its not actually true about jetting to 1.8
they should be jetted to 1.8 to start with and get it up and running then it needs rolling roaded to set it up correctly mine had 1.8 mil jets and the power increase was nothing until we DOWNSIZED the jets to 147.5 mil then the power shot up to 185bhp and 161bhp at the wheels so it all depends on engine wear and tear and spec its the cheapest reliable power increase imo apart from nos and the carbs are a piece of piss to maintain and can be overhauled for as little as £30 so far cheaper than webers and better all round also you will need a choke cable and a motorcycle brake/clutch cable for your accelerator
