Thanks Mec, I appreciate your help! Hey what do I win for having the closest guess? I'll have to go back thru your engine specs now to see how your engine differs from the 1026cc engine I'm building, 113 RW BHP would be lovely!

G'Day Mec, sorry I've been away for a few days and have missed the latest developments, but I'm guessing around 100 BHP at the wheel would have to be about right? More importantly that engine should be really torquey, and with the light weight and your own slim build, the accelleration should be phenominal!

I've just obtained (from another member here, thanks Wayne!) a NOS Egli race fairing and some body work (Dunstall? Rockman? Egli?) that doesn't fit on a my CB750 properly so I'm thinking about using it on my "Tegli" build, do you have an actual plan with measurements etc for your beautiful frame that I could have a look at mate?

Do you think T316 grade annealed AW Stainless steel tube (1.6mm wall thickness) would be OK for the frame, or would it be too brittle? Cheers, Terry.

hello,

sorry, terry, I do not have any plans or drawings because I took all measurement directly from a oem stock egli, altered them to my wishes and did the work.
however if you wish I can do some measurements and let you know.
I was not very successfull in investigations on your T316 stainless steel tube. but what I fear is, that this material is all but not the best choice for your demands. stainless means it does not rust? there is no non-rusting steel for our frames, as you said too brittle, just my 2 cents.

Hey Terry,

I have some drawings taken from a EGLI, if interested I can scan and mail them to you.
I for one should never use 316 for a frame, specially round the welds it will crack.
Cheers. Rob

Hey thanks mate, I'd appreciate any help you can give me, so whatever measurements you can provide will be great! The main reason I thought about stainless was so I could polish it, but as you and Rob have pointed out, it's probably gonna be too brittle, so I'll have to re-think that idea.

I can take your beautiful beast for a test ride? Woohoo! Thanks very much mate, that's worth the airfare to Austria alone! Cheers, Terry.

Yes please Rob, that'll be great, I appreciate your offer mate! Do you want to mail them, or email them? If you want to mail them I'll send you my mail address. Cheers, Terry.

Suggestions? I suggest that you have failed miserably and you should ship that bike immediately to my house for proper disposal. I'll do it for free as a personal favor but you OWE me next time.

and what when you are not able to handle the exorbitant power of that beast?

I will cross that bridge when I come to it. I'm not scared. Ecosse and I can share the burden....

Don't get yer hopes up boys, by the time I've taken Mec's beautiful bike for a test ride, there won't be enough left of it for you two to even recognise it as a motorcycle, let alone offer you any bragging rights, either here or in the after life!

Er, just kidding Mec, I'll baby it!

mec, a suggestion: pretty hard to top your self obviously so my suggestion would be to begin a polling thread for project ideas.

But seriously, where does one go from the DIY Egli?

mlinder · « **Reply #185 on:** March 21, 2009, 06:09:43 PM »

He'd have to build his own engine from scratch to top this, at this point.

Seriously, because I often obsess over this bike, ideas surface, and had one I thought was good.

Why not build an open road highway tourer capable of keeping up with more 'sporting' bikes? What I mean is the heart (frame) of an Egli but tank, seat, controls, of a standard. A bit like a road legal (1980's US racing class) super bike that can be ridden at length with comfort.

billybobobrain · « **Reply #188 on:** March 21, 2009, 06:58:50 PM »

How about a fire breathing 2 stroke, built with a modern snow machine motor coupled with a Harley 6 speed gear box.

Hey I can't build it so maybe I can see it done by someone who obviously has the talent and resources available!

Ecosse · « **Reply #189 on:** March 21, 2009, 08:36:34 PM »

wasn't konig's bike a 2 stroke snowmobile mill? ah, and a spine frame... hmmm. Konig, isn't that german? what is it with that part of europe? mec, if you have pix of past projects i'd love to see.

i'm part german but i seem to lack the technical genius gene. darn french blood! my scot side just wants to drink and fight so that's no help.

sorry mec, i really am trying to stop this hogging in other threads stuff.

mec · « **Reply #190 on:** March 22, 2009, 12:46:32 PM »

hihi, funny guys. I love your humor.

the König was a 4 cyl watercooled 2 stroke boots engine http://www.ozebook.com/konig.htm

I will not ever build a chopper. I love the look of fine build choppers, but handling and performance on the street is s*§$%/. always working with steel is not a challenge at all. thats boring. racing bikes are made of carbonfibre, titanium, aircraftaluminium, ceramics, magnesium, beryllium,.....

I do not want to touch a two stroke engine. they are known to cause cancer, or was it lepra?

look at side 4, end of the side, there is my spine framed bol d´or from the 80ies. maybe you can take that as a basis for your idea?

back to topic:
I have seen some drops of oil under the transmission cover. it was time to hylomarisize

the gasket. doing the work I took notice of more oil in the regio of cyl 2, exhaust side.
I decided to do the first engine maintainance instantly. all in all it took 3 hours. to have access to all zyl stud screws I lowered the engine at the rear. at this time I saw that the oil from cyl 2 was an error. it was not oil, but it seems that there was gas/oil from the mishap with the blown spark plug on the dyno. it was fuel from the exhaust port. so everything was fine. I removed the cam cover, camshaft and all the stuff above the head. its always the same with new assembled engines. after a short break in period every second screw is more or less loose. some cyl studs had to be retightened half a quarter of a turn. no wonder, why many engines have leaking cylhead gaskets when not maintained properly. new oil and a new oil filter and the work was done.

there had been troubles with the Ti bolts in combination with Ti nuts.
despite having greased all the threads, it was not possible to torque the nuts in a proper manner.
torquing to the right torque, the nuts made a crackling sound and had been tight, but the bolt was loose

I replaced these nuts with AL7075 nuts and everything was fine.

the next days I will track test the bike. but I am not sure, if it will be possible to do a lot of laps because the front fork seems to be not stiff enough, maybe the springs are too soft.

Geez, that's an unpleasant development. I'm not familiar with titanium fasteners, what do you think is the problem?

I am neither an engineer nor a fastener expert, however:
Since you greased the threads, that reduces the needed torque pressure (when measuring by way of a torque wrench). and if they cracked, or went into yield, then shouldnt the bolt be replaced when it comes loose again?

This is more of a question than a statement btw

HavocTurbo · « **Reply #197 on:** April 10, 2009, 01:29:28 PM »

I didn't think that Ti bolts stretched.

But I'm no metalurgist. (did I spell that right?)

hello,

the sliding properties of titanium are really bad. if you once try to mount a wheel axle, you will see, what I mean. this uncomfortable character of Ti will prohibit to use as transmission gears or bearings.

the problem is solved by using Al nuts.
btw no Ti bolt or nut is damaged.
