Dont know much of sus just that they have bad rep for those who dont know how to tune them and they produce 20% less power in same setups as twin webers but thats cause they are only two but imagine if you run a custom setup with four?(I saw a jag six with 6 in japan and the tuner said they worked better than his previous weber setup and he wasnt a pom but a jap) Surely the angled design straight dump path and tuning flexibility will more than match webers. Plus the 2001 r1 bike produces more than 150 hp with four su type mikuni carbs that arent four flat sliders. Its all too confusing arghhh!

Correctly tuned SU's in good servicable condition should need no maintainance apart from checking the oil in the dampers periodicly. Correctly tuned Webbers should not need touching at all.

Comparing Su's to Webbers as a general blanket statement is like comparing ships to airplanes. If you want to compare, then be specific. Be very very specific about carb models, the specifications of each, & the intended application.

I ran a stock 1200GX setup for about 15 years with the Japanese SU's [Hitachi's] & they have never given me a moments trouble. They provided acceptable performance, good mileage, were trouble free, allowed the engine to start quickly, hot or cold, & ran nice & quietly behind the stock aircleaner. They were affordable, & came pre tuned by the factory engineers. I do not know that Webbers would have offered me all of that without a BIG spend.

Oh yeah, i major overhauled my Hitachi's before i used them, with kits & parts from my friendly Datsun Dealer. Got trade price too. What a bargain.

I am not a great fan of British engineering, but when they get it right, they really get it right & this carb design has been around since the early 30's, & probably even earlier. Why wasn't it discontinued long ago? Because NO ONE came up with a better mousetrap. The design was used on just about everything from mongrel Morris' to bloody nice Bentleys, to Merlin aircraft engines. Same basic design.

Pick a Webber design that can match that. Webber carbs can be very good, but they are not the only game in town.

 Re: its a beautfiul site!!!
yep, that's el coche mio ...

these are normal 1200gx hitachi's. same size as 510sss, but with different needles

the aircleaners are generic offroad "bugpak" items, clamped around original gx airhorns

a guy looked at my motor once, noticed it was sort of vintage looking, and then bitched about the modern gel battery ... thanks!?

 Re: its a beautfiul site!!!
i'm sorry but twin webers on an engine like that would be an overkill. a good single 45DCOE would be all that's needed if the weber route was chosen. saying that "this produces less power than this" etc etc is no way to look at it. try getting ANY throttle response under 2500 with a twin weber setup....

SUs are a good carb and Dodgeman is right, lots of manufacturers use them (or copies of them). even the 1992 mitsubishi lancers have a downdraft version of the SU!!

i don't know whether i would say "SU's are the worst carbies ever" when tuned right they give the nicest sound you could ever ask for and excellent performance, i have twins on my A15 and the throttle response is amazing, even at high speed when these things scream i just fall in love with them.
