Hiya All,
Me again.....Finshed study now so back to the bike....  I am finishing up fitting a T250 rear drum to my CB but am having a little trouble working out real centre/spacing.... What is the best way of doing this (that is, where is the best place to measure from)? The CB swingarm seems to be offset slightly on the left side, so the measurements differ from side to side making centering and exercise in confusion.......ie; if I get it centre from the front of the rim, it is then out of centre when measured from the hub to the swingarm sides..... just stick with measuring from the front of the rim to either side of the front of the swingarm?
Also, when it is finally centre, the sprocket will be slightly (around 2mm) out of alignment, would this be OK, or should I then space the sprocket out from the hub?
Thanks people, I'm just not quite sure what kind of tolerances are acceptable...
Cheers,
Ben.

Well you have 2 problems..
1 sprocket alinement
2 wheel alinement
use a straigh edge for sprocket holding straigh edge on rear sprocket!!
then use string line around both wheels BUT rear and front are of different width and see which way and amount that the rim has to be pulled across inother words reset spokes good luck!!
3 Also if using a different front wheel make sure that it is centered between the forks if not this is the first job to get correct!! |

G'day Ben,Allan is right ,check front wheel is center in forks,also string line through frame centre to confirm this,tip ,use fluro whipper snipper line,wrap round front wheel at front,down low both sides past rear,then wrap around house brick behind rear wheel(leaves your hands free!!)centre front wheel rear equal distance between string line,rear wheel must sit equal distance between line also,get this right before worrying about sprocket alignment,wheels centred,then move hub/sprocket (via spokes) to line up with c/shaft sprocket,easy mate  cheers  |

Thanks Mateys, It all sounds good apart from Spoke adjustments.......... I tried to true a bicycle rim the other day.......... mmmmm needless to say I ended up paying someone to fix my mistakes............
The front is centred, hope fully I can get the back sorted without complications (ie, me making a mess of the nice Borrani).....
Cheers,
Ben.

Ben there are two other solutions;
1 turn it into a sidecar and you dont have to worry about anything ;
or
2, just tune it right and mono around the circuit, should attract a sponsor soon enough for being a show off and then you can buy a bike already set up.
See its easy. |

Buying a bike already set-up? Isn't that cheating?

No Ben, that is common sense............. a trait most of us are lacking...........
still a set of functional carbies short of a functional bike here, at least yours runs. |
Life may not be the party we hoped for, but while we're here we may as well dance |

Thanks people, the string method is a winner, and I found an old sprocket that can be used to space out the existing one to the right place (thanks Mick ) rather than adjusting spokes. Excellent, now I have a reason for keeping piles of rusty crap in my garage.
When are we going to hear the story of Popeye? |

When he finds a set of carbs.........still looking for cheap ones but may have to bite the bullet and buy a pair of new ones from the US, not too steep at US$275 including cables and mounting gear. That and the tyres will double the investment in the machine though.
LATE NEWS.......... carbies will be here in about 8 weeks, 34mm Mikuni's brand new, looking forward to working on carbs not full of crud.... price AUD$125 each. |

Nice!
Where are you ordering from Popeye? Does that include postage, manifold rubbers/cables? They are over 200 a piece here............. Pays to shop around!
Sounds good for mine as well! |
