Jeez - I might have to start another "No NO NO and the REAL idiot is..." thread! Why I never checked the carbs and set them all up before bolting them on is a wonder even to me. I'm usually very thorough but for some reason - bank of carbs, on they go! So here's the final tale of the tape....

Needles - should be R CZ, they are all R H3
Air screws - one turn out - actually they varied from half a turn to one and a half turns
Air jets - should be 200. One is 200, the other three are 250
Slow jets should be 60s, three are 55, one is 60. Only the 60 has the o-ring seal, one of the 55s is broken in half
Cutaways - OK all #3
Now for the killer - main jets should be 115. Two are 120 and the other two.....

......are missing completely!! No wonder the thing wouldn't fire. So all I need to do now is find all of these totally obsolete parts and I'm laughing....bit like the bloke I bought the carbs off....

Hard to start?

Our full race CR750 used standard timing. Set the spark to fire at standard setting. Does this system use the original advancer?

If it does not....somehow the magic part of this Boyer thing is not working?

Tickel carbs until fuel runs out of each and every float bowel.

Use just a little throttle opening and it should start up in FIRST gear.

Never ever.... used a higher gear to start ours.

I can sell you a foot starter for only 100.00 US, shipped to anywhere in North America..

hei LMP

with that nick and the list of race bikes you own, i thought you were a serious guy :-)

LOOK! It's all of your faults, not mine!! It was you lot that pushed me to finish the flamin' project and it was you lot that made me try and start it before I'd checked the carbs. This forum is just too much - it's like being hypnotised, I wasn't operating under my own free will.....

OK OK so maybe I was in a little bit of a rush too, you gotta laugh!

turboguzzi · « **Reply #31 on:** July 31, 2009, 10:01:15 AM »

while you are at it, give the poor carbs a good clean, might help :-)

lordmoonpie · « **Reply #32 on:** July 31, 2009, 11:42:48 AM »

Hey TG - surely I don't need to do that I mean the PO must have claened them before he sent them to me

Actually - I did the cleaning of them a couple of years back - I just can't believe I didn't check or see any of the jet issues!

Time to go and see if I need some glasses LOL!

Terry in Australia · « **Reply #33 on:** August 03, 2009, 05:26:14 AM »

Will modern CR parts interchange Simon? Geez mate, you must have the patience of Job, if I hadn't gotten my bike started as soon as it was all together, I'd have burned it by now, ha ha! (lucky you didn't try the raw fuel method, with those old carbs in mechanical disarray, you probably would have burned it!)

Hurry up and get that fcuker going mate, we can't wait! Cheers, Terry.

MRieck · « **Reply #34 on:** August 03, 2009, 05:31:58 AM »

I think the real problem is Simon didn't spend enough money and he rushed the project.

lordmoonpie · « **Reply #36 on:** August 04, 2009, 03:28:35 AM »

LOL! I think I'll build a wood burning engine for the next bike and just feed it with fivers!

Well the new 115 main jets jets arrived today so they'll be going in tonight along with a float height adjust. Terry - the main jest are the *only* modern keihn part that will fit sadly.

However, that fine gentleman Mr McGrew (kos) is arranging to send me the other jets even as we speak so global mail willing, I should be ready to have another go within the fortnight.

Terry - the secret to patience in these situations is simply to have another six builds ongoign at the same time. hit a problem with one and just move on to the next while you sort it out. There is the minor issue that none of them ever get finished but at least it keeps me away from the beer in the fridge >hic!<

Aaaah......... very good point Simon, I've been doing that for years without realizing!

Mick (Retro Rocket) sent me some Ceriani forks the other week which spurred me onto doing some work on my endurance racer project, but on Friday my big brother called me and offered me a "deal" on his 2007 Triumph Rocket 3 Classic with only 24 Kilometers (about 14 miles) on the odo, (long story, which I'll tell in my next "Terry's Motorcycling Adventure" post in a few days............) I had to have it, as I haven't had a "new" bike in 30 years, so sadly the endurance racer project is "on hold" until I pay the Trumpy off. Oh well...............

LMP,who makes cam chain in your engine?,Hang in there you'll get it.Bill

lordmoonpie · « **Reply #40 on:** August 09, 2009, 04:40:55 AM »

Hey Bill, the camchain is a regina chain bought as a rivet link DOHC honda length then cut back by two plates. Rivetting the hy-vo was the worst part of the whole build and I'm still not hapy with it. If that rivet lets go....

Terry - good to hear from you in Oz, clinging to those ashes by your fingernails, if only we'd had a bit more snow...you know it makes sense to buy those bikes up - I mean if you didn't they'd get neglected and start to rust away which is a terrible shame. Think of it as a humanitarian cause

Terry in Australia · « **Reply #41 on:** August 09, 2009, 05:31:26 AM »

Ha ha, thanks mate, "her indoors" just walked up to me and asked me how I'm going to pay for it, a couple of days after agreeing that it was a good thing, and just after I've booked my flights etc. Bloody women, always finding a negative in a positive! Anyway, she won't deter me, it's too frigging late now!

Re: the cricket, your blokes have done surprisingly well today, it may well be a contest after all! (but we're still gonna win!) Cheers, Terry.

HondaMan · « **Reply #42 on:** August 09, 2009, 08:22:54 AM »

Hey, LMP:
Here's a possible method, if you have the parts around: stick in a set of stock carbs to get it running, then switch to the fancy ones after you know it will. (I'm essentially lazy and in a hurry, so that's what I would do...

).

lordmoonpie · « **Reply #43 on:** August 10, 2009, 04:53:42 AM »

Thanks Hondaman - I looked at that and when I dug out my standard CB carbs they were even worse condition so back to the drawing board! All of my other bikes are twins or singles so I can't even rob some off another bike LOL!

lordmoonpie · « **Reply #44 on:** August 12, 2009, 05:05:50 AM »

ooooo! The wife has just emailed me - small packet arrived from across the pond with M3 printed on it...could be the missing carb bits!!!

Could also mean that I might be on for a decent starting attempt this weekend, woo-hoo!

voxonda · « **Reply #45 on:** August 12, 2009, 05:37:40 AM »

And if not, I think we all should come over and 'help' you a bit!

Cheers,

Rob

lordmoonpie · « **Reply #46 on:** August 13, 2009, 02:47:27 AM »

Well I can confirm that Mark has indeed supplied me with the missing parts and he is indeed not only the king of speed (kos) but a prince among men as well!

The parts went in last night and float hieghts all adjusted so I have a consistent and standard setting for all four carbs. Then I went to push them back on the carb stubs and it all came flooding back!

These new carb rubbers are so darn hard it took me days of swearing, cursing and even a pulled muscle to get them on last time....back to it tonight I hope to get them ready for a weekend starting attempt...

Mark - my thanks for your help will be in the post to you tomorrow. If I get to Hawley at some point in my travels I'll buy you a nice cold pint of Guinness or two

turboguzzi · « **Reply #47 on:** August 13, 2009, 01:58:51 PM »

there are quite few ways to make it easier LMP.

one of them is to seek support from ratcheting tie-downs. wrap them around the carbs and head. each time you get the carbs in a bit, pull them down and got to the other side and do the same.

a hair drier on the rubber helps too as well as greasing the inner bore a bit

with a pulled muscle you wont be fit to race!

He's not fit to race anyway TG, he's to fat and old

Try a little smear of fairy liquid in the rubbers Si.

LMP,you catching hell this mornng,it's Ok,you still OWN the CR750!,It will run,but I agree w/TG,I would check everything,2 yrs long time ago,Glad it didn't crank,would have sounded and run terrible caught on fire and burned,then your post would have been ROAST like the bike!Don't think you'll need it but keep small fire extinguisher close by!I thought that chain looked kinda familiar,Who else has done this this away? Looks strong!,Good Luck,Bill
