RE: weeeebers

[Terry Rudd]

Ben,   If your webers wont rev an L engine then then it's pretty simple - they are running out of either air or fuel. My guess would be fuel as twins are usually setup on average way too lean. Remember that these carbies are designed for racing and not your average street driver. They should be fairly cranky below 3000 rpm and then pull thru to 7000 rpm but tuners don't set them up this way as the customer wants smooth power from 1500 rpm and no bog down of the line - that's pretty tricky to achieve even on a fairly stock engine. You cant have it both ways with them and get 30-35 mpg around town, you should accept 22-25mpg around town and 30+ on the highway cruising.   We haven't done much weber analysis for a while on here but give us the specs of your engine and what jets, e tubes etc are in your carbies and we'll give you an idea of what you're looking at here. We used to be pretty good at this sort of thing a few years back, prolly a bit rusty what with EFI & turbos these days.   regards Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Ben Sent: Friday, 17 May 2002 3:22 PM To: [EMAIL PROTECTED] Subject: weeeebers righto, last time i had my DCOE40s on, they would scream like a bitch from 3-5.5k RPM then stop dead...i just though it was the cam, but now after changing back to my original carby, that revs out fine to 7k (not really fine, but gets there ok). im gunna put the webers back on, and i jsut wanna knwo what needs changing to make the rev more....surely since a 30/34 hitiachi can rev ok to 7k, twin 40s should easily make it.  what needs changing, it has 36mm chokes so they cant get any bigger.....thoughts please??? --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
