Who from Sam - where do we send the wonga?! 

[Sam Green Racing]

I was scared of asking for a photo after you mentioned the leaver

Whilst we are on the subject of Fuel tanks and everything belonging to it...
I recently bought an fuel tap along with some other parts.


In the partslist I have got are the following parts stated:

Carb. Assy., CR            16100-300-970   
Carb. Assy., CR            16100-300-971   already on the shelf
Insulator A            16211-300-970   
Insulator B            16212-300-970   
Cock Assy., Fuel            16950-300-970   just delivered
O Ring, 125x35            16997-300-970   
Tank Comp., Fuel            17500-300-970   
Clip, Fuel Tube            17502-300-970   
Band, Fuel Tank            17503-300-970   is this the other part on the photo?
Sponge, Tank            17504-300-970   
Pad, Fuel Tank            17505-300-970   
Tank Comp., Fuel            17600-300-970   

I have already got an fuel tank made in Germany which should resemble the original as much as possible. However the "lump" on the bottom side is not an accurate one.
Could somebody show me some pictures of the other parts wich are stated above and the correct form/shape of the bottom lump.
I have already seen that there is some sort of boss around the Cock Assy and it should be fixed by bolts or studs (i suspect the latter)

Thanks in advance

[napoleonb]

These are the photo's which a deem most likely to be original (Kit at least)
Were there much differences between the kit and factory bikes on the area of the bottom lump?

[napoleonb]

Is there nobody among the regular visitors who can clarify antything?
I am assuming the bottom lump of the fuel tank to be longer for the Dick Mann bike and the rest of the dimension to be the same.
How is the back part of the tank secured with rubbers?
Is that with the Pad, Fuel Tank 17505-300-970 and does anybody know a part which resembles this as close as possible?

[Sam Green Racing]

I can't recall the detail of the sump as I like a lot of people never saw the Daytona tank.
The tank on the one I built was copied from a kit tank but with a Monza filler cap.
The tank is secured at the rear by the rubber and wire strap which you posted before the tank pictures.
As I never saw a full list of kit parts with numbers, I am at a bit of a loss about the pad and sponge.
One of them will be the cushioning that goes in the recess on top of the tank for the rider to rest his chin on.

Nap, Thats quite some impressive tank you got made there!! hope you get it sorted out. I have no idea and having a hard time just figuring out if I should go left or right with my own project 

[napoleonb]

Jimmy, that's not mine unfortunately..

If you want a chin pad sponge, head on over to the CR750 resource page at ww.moonpie.co.uk

[napoleonb]

I already found that part, assuming that's the Sponge, Tank 17504-300-970
Yesterday I had a chat with Paul mcGhie he is going to hook me up with the other part.
It will take him a few month's to let this part be reproduced but I've got the time.

So my mysterie is solved.

I didn't bother asking for a photo of the cap as Simon lordoonpie had already had dealings with the company and was not impressed with their products.
At the weekend, I met another guy with one of their caps and got the same responce, CRAP.

Proceeding my way of adapting my frame, the next question arose.
I know there is a bush welded into the frame for the right side gear shift conversion.
Do any of you have the dimensions of that bushing (I am assuming it is just cilindrical) internal diameter should be sufficient to determine the bearing.
Which if I am not mistaken is no 5 in the picture down below.


But if any of you have the info to complete the picture above (part numbers or dimensions) I would be very gratefull.

[napoleonb]

Anybody who's got a clue?

[ttr400]

Hi Nap,
I am busy doing the same thing to my CR. I can't help with any part numbers, but have worked it out from pics. when I am a bit further along and have some parts made I will post some pics.

[lordmoonpie]

Why do you guys want the gear change on the wrong side? Is it all just in the name of "Daytona replica"??

[malcolmgb]

Hey Simon they maybe cut their teeth on old british race bikes
When my mate bought his new TZ250 back in the 70's he thought he could adapt quickly to left side gearchange after many years using right, after all he had bought a Yamaha road bike and that was easy. The first meeting was a nightmare missed gears and he was all over the place with his braking too, straight to Granby Motors for a longer rear brake hose and he was back to right change.

[napoleonb]

For me it's formost about the looks of the system but "authenticity" and the technical aspect are also reasons for me to adjust the gear shifter.
Besides photo's I don't seem to get lucky with concrete measurements. And I imagine there there are quite a few bikes with the adaptation in place.

I suppose that'e my question Nap - it's just to create an authentic Daytona bike as oppose to a racing 750?

Love the anecdote Malcolm, reminded me of my time racing a 250 ducati - I could change gear OK on the right until I got in a panic and always went the wrong way! How the poor little thing never blew up I'll never know

This should be posted in one of many the CR threads on this site as it has no relevance here. Mark {kos} has gone into great detail about these bikes on this forum and IS the resident CR expert on this site and probably the most qualified person {on the planet} to do so, trying to "one up" him in someone elses thread is poor judgement in my opinion.
 

give me a break! i'm not trying to one up anyone. and the ''french'' daytona bikes (or at least daniel mercier's machine, which is almost certainly one of those) have been mentioned on this forum previously. i was lucky to have seen one first hand in 1970, i've been asked to post whatever photography i thought would be of interest, and that's what i did! in exactly what forum do you feel it would be appropriate to post this content?

patrick,

as someone who started his path in this forum some four years ago with wrong foot (and got bashed too) , all i can suggest is that you try and catch first the spirit of the "place". We are not magazine readers reading your amazing personal stories over glossy pages, just simple and mostly poor, (simon LMP aside ) guys who love playing and racing sohc4's. This is one of the best and friendliest forum in the biking world and I've been to a few. so just relax and talk to us on eye level, we care more about valve seat cutting angles than VIP stories.

And welcome to our forum

I removed my last post here because i was mistaken, for that i apologise, i thought i was in the CR fork thread. Just remember though, you came onto this site swinging at an established and reputable member who knows these bikes better than anyone so expect some flack, the list of guys that Mark works, and has worked with and his trophy cabinet and achievements speak volumes for the guy and his knowledge of these bikes, nothing you can say will change that fact. And in future use the PM's for personal contact, the email addy is for business only....

i don't know tg... honestly... i'm not sure this makes sense to me. i would think a forum should allow as broad a range as possible of content and professional background. i mean, on the face of it, this is in many ways a forum that celebrates history as well as practical and technical topics. it seems to me that well wriiten, detailed in-depth content should have a value here. i don't consider myself a vip at all (although on occasion i've received that treatment as a member of the press and often it kind of bothers me... even if there is a vip sticker on my fiat from having attended the imola 200 revival). but if i were a vip, why should i be made to feel uncomfortable?

maybe this just isn't a good fit. i'm seriously thinking of withdrawing from this whole deal. i've had a very stressful life the last several years and don't need any more angst... especially, through something that has been near and dear to my heart since the age of 14. all the more disappointing, since, by necessity, i had had to set motorcycles aside for several years and felt that now i had time to orient myself back toward that world and that this forum might be a useful part of that process. but maybe i just didn't understand this whole forum business. that's entirely possible. i can certainly direct my energy elsewhere; that's not a problem.

thanks, for the advice just the same.

[ttr400]

Patrick, please keep it coming in any form you desire. I am enjoying your accounts of the Daytona bike as I am trying to build a replica myself, so any info is welcome.

Welcome to the site.
