thanks for reminding me that i left this open ended slabghost. i wish i had a success story to share,even tough i definitely needed to replace the old cracked/broken caps .i was unable to resolve the issue with the shinny new ngk caps,i went back to single carb until i can acquire a pair of new...

dan if there are any specific info in that hanes manual for the weber 40 idf series 70 id be very interested to read because thats what the empi 40 hpmx is supposed to be copying .

here are a few more pictures of my hex bar adaptation

Thanks very much guys for your replys and interest guys this evening i installed the new resister caps as suggested but no ride report because --well i had a few of our great local craft beers with dinner and uh -- you get the idea.

well thats worth a try and i have a new set of resistor caps to install,ill do that after work tonight

dan im runnin a factory1200 ecm powered by a confirmed good relay firing dynatek green coils 7mm solid copper w/no resister cap ends iridium ngk suspect carb side plugs look definitely lighter in color then the other side.

iv learned that the idf has three separate fuel circuits idle,midrange transition and main each has an effect on the other in different throttle plate positions and vacuum levels. im confident in how the idle jets and mixture screws act and respond im unsure how the transition circuit is being...

cool thanks slabghost with that ill lay out the facts and symptoms as i understand them

In starting this thread I was hoping to reach out to the folks here who have experience with this type of downdraft carb never having put my hands on an idf weber before, maybe start a discussion of there specific characteristics and how they might relate to oldwings of different...

Yes slab i feel i may have balanced the luck of the draw by receiving one ok and one junk carb from empi. as for vacuum gauges this synchronizer tool i have from tech-mate is pretty cool if you ever get a chance to check one out.i can actually drive and watch the balance of all the carbs as...

Thanks joedrum i agree with you on the dft, im running one on my wife's '83 1100/1200 as well as the perfectly good rig i removed from this bike. both make me smile with their performance and reliability but i was just exploring another avenue. i guess the reason for my post was to seek out...

yes im running one size larger idle fuel jet then recommended on all 4 and realy backing out on the mixture volume screw for that cylinder seems to almost mask it at speed but my idle becomes more than fat and sassy its sooty and eye burning in the shop.

also i have disassembled,cleaned out all manufacturing dross from both carbs in an ultrasonic cleaner twice blown out all circuits and verified transition ports 4 times,checked throttle plate alignment,and float levels. fuel pressure is a steady 2 lbs carbs linkage mechanically synced as well...

yes Denver cruising down the road with aircleaners off i can spy and hear#1 slight backfire an issue that followed the carb after i swapped it from left side where it was #4

Ok so i cant leave well enough alone. basic stats. of project '86 gl1200 with gl1100 heads and cams,compression 155-160 cold, wot. new dynatek green coils 7mm copper wire w/no resister caps, iridium ngk, stovebolt tom's weber atop a vw plenum welded to1" sch. 40 runners bushed for gl1100...

thanks Joe Ill listen to whatever input/insight you offer up.Ill try it I'm game,within reason or budget of-course.

I hear ya joe there is fineness involved where the grinder is concerned. like having the discipline to put down the paint brush and stepping away and calling it art. Ill check the tolerances assembled as you and slab suggested and let er fly if there is no interference I know my relief cuts are...

thanks zman i was just wondering in general without using clay, is there measurements available for the depth of cut ?

so i have some updates to relay i picked up a pair of 1200 long blocks i feel are prime candidates for hoochafacation. this week end dident have much time but i made some progress i think. my first attempt at valve relief cuts. i was looking for anybody that might have an idea how deep cuts...
