A stop light is also required but many testing stations either ignore this one or don`t realise it is a requirement.

No there shouldn`t be any movement - make sure the return spring does its job and have some freeplay in the cable.

I gather you have now sorted the problem but as a matter of interest, try running without the filter to see if there is further improvement. I ran my cub with the 1/2 moon type filter and it was too restrictive (the stub dia.on the outlet was too small).It revved out fully without a filter and also with a K&N fitted.

The reference number is TG 452 (can`t remember if this includes number of teeth but Talon will know.) This is for a GB gearbox , not a Gp as you have described. ( do you mean CP or GB ?)

Talon do a 15 tooth for the GB gearbox (ideal for trials) but don`t know if they do a 19 tooth. Phone them on 01935 471508.

Hi Been using a clutch without cush drive for years - no problems Cheers

Hi A friend wanted to register with TC but firstly had trouble finding where registration was explained and then found that the submitted e-mail address would not be accepted. Could someone please explain how to register, it`s not very clear. Thanks

Hi GII Here is my amended reply Talon Engineering made them for Serco but they required a separate spacer. I got him to order some 520 sprockets to the same dimensions as a standard cub one - don`t know if Talon still do them.

Hi GII Talon Engineering made them for Martyn

Hi A 160 main jet sounds too big, i am running a 130 on my 410 ajs and 110 on my 250 cub so a 120 shouldn't be far off. Cheers

Hi Was it rich throughout the whole range or a particular bit. Can't think why it should suddenly go rich but worth checking the float level anyway. The best setting is when the top of the float is approx. 2 mm below the top of the bowl with the float needle fully seated.( Press on the float tang, not the needle, and make sure the float pin does not move up out of its seat.) Good luck

Hi, Have you got the quadrant the right way round - when correct it the boss on the end should line up with the window in the inner cover. It is then simply a case of inserting the pin through the holes ( a bit of jiggling will be necessary ) making sure that the small hole in the pin is in line with the one in the camplate and then install the split pin. Good look

Assuming you have a 14 tooth gearbox sprocket, if you require a 1st gear overall ratio of say 30:1 then calculate what size engine sprocket you need and get one made using the spline from your existing welded to a machined blank. Alternatively. see what Talon Engineering can do for you.

Standard road cams will be fine - I have scrambles cams in mine and it still plonks.

You can make one easily (If you have the tackle) You need a length of clutch/brake inner cable, two pear nipples, a M8 alloy set screw 50mm long and a fitting to suit your brake lever. Cut the head off the screw and then drill along the center to suit the cable diameter (best done on a lathe ) Thread the cable through the screw and fix the nipples and fitting. I use a M8 wing nut to adjust but the choice is yours. I have also covered the cable with shrink fit plastic sleeving to stop wear and rusting but this must be fitted before the last nipple is fitted
