67` Bomber running problems

[mo goldie]

can anyone supply the following .....as a bloke has asked if I can supply them he will see what he can come up with if anything ?

so he said if you supply me with the diameter of the centre hole and the p.c.d. with hole diameter and the number of holes and the chain pitch

well I Know it is a 530 pitch chain but Not the other bits 

[Bryanj]

Do you not have an old sprocket to give him?

[mo goldie]

Hi Bryan

Well I am using the bike so don`t want to take it off the road yet if you know what I mean......... so just wondered if someone has one already got one off that they could do a dimension check ? 

[Bryanj]

Have you considered that running 17/35 sprockets has dropped your revs for running speed and may be contributing to your running problem? It was designed to cruise at a certain rev range

[mo goldie]

well I might have to keep the set up then as a 15T and 35T ......... the running of the bike is fine now ..well near on anyway ..but the revs just seem to be so high

oh the other thing is I have been on the DSS and looked at Ashley`s parts list and they did do a 17T sprocket for the Bomber so it must have been able to run with a 17T ha

[Bryanj]

Honda always list alternate sprockets but they were designed with a ratio and yes, compared to british iron, they do seem to rev high BUT its higher up the rev band they give rated power, the 500 handbook says not to go out of the top of the red too often

Cursing you today Mo ... 'cos I had to go to the bowels of my stash to find this to measure for you. 

4 mount holes around 9.7 mm Dia. Large centre hole 73.7 mm Dia.

Well it went OK 'cos I found a NOS one in there for my own Bomber I wasn't aware I had  and didn't realise they are so rare !

[mo goldie]

are goodo then Ash I was some use ha......... pity you did Not Have two ha

that would have made it all the more worth while

Hi Ash

This is what he sent back so if you Know what he is on about can you have anther look at the sprocket please to give him the more info.

Hi, You have not said what chain pitch you have but I assume it is 530. The 4 mounting bolt holes distance apart (known as the p.c.d.) is taken from the centres of the bolt holes.
I make it 74mm centre hole as there is nothing listed with 73.7mm. The p.c.d. at 110mm with 10mm bolt holes.

Is the sprocket flat on both sides or a recessed ring on the inner face? I think it might be 280 sprocket type but I now need to check to see if this is still available.

May be simpler if I donate my used one to you to give him. Just pay postage.

[mo goldie]

Well he is just a bloke on Ebay Ash so don`t know how good he is..........as he just asked to supply the dimensions so he could check to see if they is one to match it ..... so if you can just tell me if it is flat on both sides will due I think.   

[Bryanj]

Part number is 41201283000 so i would say 283 not 280 but that is a pure guess

[mo goldie]

You have lost me with that one ?

tried them in DSS and all discontinued
