    Not sure if you and how you aligned your sprockets, but something like this is the only way to measure propperly, you put this on the front sprocket, because your rear sprocket can go on an angle and that screws up your alignment.

     

    When I did mine I did it with strings and long pieces of timber, thought I did a good job, till I changed the rear fork bearings and deceided to have a check with that laser thingy, turned out it was out by over 5mm

    I used a bit of straight bar, 5mm x 25 mm ish. Laser seems worth a spin though to check.

    The bike rides straight enough, and chains can run quute a bit out of line.

    3 to 5mm between tyre and chain minimum is what I would go with, others may say different but that is my preference. A correctly tensioned chain will not exhibit any lateral movement so will not rub. Are you using an offset front sprocket ? and also using 530/525 or 520 pitch chain?

    Hi Jonboy 

    I've got a flat 530 front sprocket. It's spaced out to the maximum, to still be able to use the locking tab as std.

    I foolishly bought a 5/8 offset one, and it was way  too far over.  A slight offset maybe 2 mm wpuld let me turn the rear sprocket, then I think I would have enough room for a 180 rear tyre.

    had a similar issue with the rear wheel "tightness"  I found that the K series rears have a wider hub than the Busa, so i swapped mine & line up was a tad easier. 

    But same as you, i had to shave down the carrier bolts. I then bought some tab locks & 1/2 nuts to sort that issue ;) 

    Third pic is a shaved down carrier which can also give you more mm's to play with. Oh & a 180 tyre :)

    I dont have much space between the chain and tyre, what do you think is a reasonable minimum?

    Hi,

    Ive not yet checked the timing. The mark looks to be on a piece of tin plate behind the adjustable back plate. Depending where its sat you could certainly alter it a few degrees.

    Is this normal for this model?

    I must find a manual.

    Having read about the advance and retard fix I thought I would try that first, as I thought the theory good. 

    Taking the heel off the arm allows it to retard a little further, but keeps the timing correct as it revs up.

    Unfortunately it didn't seem to make any difference.

    I found that the needles in the cv carbs only have one groove, so I files the little plastic spacer down to 2mm from a varied 2.5 - 2.75mm.

    Spend 30minutes searching on the beige carpet for one of them, but my luck was in.

    Seemed to run a bit sweeter, so pulled it out front, and we both got togged up.

    Hit the button to light the fire, and it tried but hit compression in that way they do, and then the starter gently whirred in an expensive manner. Kit off again to my good ladies disgust.

    Back in the shed, and the rotor has spun on the taper. The nut being loose of course. The cover had been off before, and lagged up with black gunk, so I should have been suspicious I guess. So as a temporary thing, I cleaned up the crank, and loctited the rotor on.

    A long bar, and a pin spanner. Hmmmm 100ftlb that is then. No gasket, but I had to test it, it was still kicking back, which meant my repair wasn't going to last.

    Yesterday was the big day then, a first ride in the pouring ride isnt my idea of fun, but it had to be done.

    Surprisingly, the handling feels very sweet, no twitches on white lines, or banding. Easy turning. 

    The motor was fluffing a bit once the throttle was opened. Feels lean at part throttle. Pulls well once it clears the flat spot. Good enough to get to the garage.

    Mot went very smoothly with an advisory for the exhaust noise.  As it should be really.

    Bit of a zip up to 90 and all seems well.

    Let the boss know all is well. Into the shed to lift the needles, and then a spin out after.

    I've been busy in the shed, getting the old girl up and running, with the hope of getting some miles in this summer, before a strip this winter to tidy up.

    The 5.5" back wheel off a k just squeezed in with some minor spacing issues, which included shortening the sprocket bolts which had an odd thread size of 10 x 1.25. Luckily I managed to get some help from a friend at work.

    The front sprocket is spaced as far out as possible on the shaft, and best as I can measure is 1mm out of line, with the rear one. I should have measured the original set up to see how close that was.

    Reversing the rear sprocket has gained some, so shouldn't be far off.
