This article could be very addictive and lead to a lot of 'trouble' or fun depending upon your inclination!

This is an extract from the article. The whole article is a real eye opener and worth a read. Potential for all sorts of ludicrous fun.
"Cams
XR200 cams may be obtained from David Silver spares for less than £50. Alternatively, due to the fact that the XR200 is so popular in the US, a used cam may be purchased on E-Bay USA – I purchased one for $20 plus $10 postage, but you must keep your eyes open. David Silver Spares also lists XR200 cams for less than £50.
The ‘ultimate engine’ builder has the option of using performance parts, such as available from Powroll ,MegaCycle or Hot Cams, but these tend to be rather expensive, so I favour the reprofile method. The reason for this is to get a standard XL125 or 185 cam re-profiled – burnt cams may be obtained cheaply from breakers, hence the cost effectiveness of this method.
Phil Joy of Joy Engineering, who has lots of experience with Honda Singles, can regrind them very reasonably to a profile you suggest or to a profile known to work well. Look here or here to see examples of Phil Joys work. Phil seems to be in Bishop Stortford, Herts, and his number in UK is 01279 730 682 or from outside UK +44- 1279 730 682. No web page as yet? Tony Brooks had a scrap burnt cam reground for 75 British Pounds, which is less than US$120 and Euro 120, and kindly provided the Contact details.
Ivan Tighe of Tighe Engineering sells cams for the Australian Bucket racers - you can see their web page Here, but I dont know anything about them. Also, an Australian firm Waggots also regrind cams, but I have no details.
Finally, the valve lift and flow scenario, mentioned above, must be considered on large capacity engines. "
Don't loose the zest, Bill
