    Speaking of CDI's, Ignijet do them as well. I might yet get one and use it with COP.

    Hi Simon
    If you use the carbs from your other bike your bike may run rich but at least you will see if it runs consistent and isolate if the problem is gas or spark. On the spark side the basics would include things like failing wires, switches or connectors in the ignition circuit. Things like side stand switch, neutral switch and clutch switch. Damage to the wires often occur where the wiring pivots or moves, like going up to the handle bars and around the neck of the frame as well as at the connector the wire joint.

    Better all round sums it up..throttle response notably better..but your not looking at huge gains..I think the set up time on the dyno paid the most dividends..but that's probably true of any carb set up. Will try and dig out the dyno charts as its easier to see..there better pretty much everywhere but 'better' is about 2-3hp..a better carb (in my opinion) but that might be biased as I'm looking at the slides/ needles/ emulsion tubes on 3 banks of bdst's and all are displaying wear, one set off an 11k (Km) bike and there stuffed. The design looks to wear prematurely - bad design me thinks. I didn't know about this issue until I read the posts on here - thanks to everyone for pointing me in the right direction, thumbs up to you too!! Got a quote back from webike £423 for all the carb stuff I need, I take on board the jets shouldn't need doing just a good clean but its obvious some ham fisted fingers have been at work before..no guarantee of holes not being oversized by paperclips wire brushes etc in the past so I'd rather do it the once..in the middle in deciding which to go for rebuild or new fcr, so also looking at other options as well..will do a bit more searching tonight..last nights trawl came up with this..now for a million yen win on a lotto scratch card!!!

    Thanks John, I'm currently waiting for a flywheel to arrive before I can progress further, couldn't find the GJ73a one anywhere in the UK(no NOS around and its a deleted/discontinued part) but have one arriving from a GF250 (predecessor to the GJ72a or gsxr250 mk1) which is slightly different but I believe can be modified to fit..i'm hoping to try out much of the above at the weekend...
