Really are you going to argue about this?.
There's people selling and wanting mountain bikes and other non related items on here and all of a sudden i ask for an engine that is virtually the same format as any other engine on here save for a few less CC's and to try and prove a point you have a good moan about it?. The last time i checked Z50R's were mini bikes and off road models at that so i don't really see what your trying to get at here. It never hurts to try these forums as there's a pretty good chance someone will have one and who are you to stop them making a few extra beer vouchers on the side?.
People can do without these child like quibbles mate so unless you have something constructive or heaven forbid something that may be of use to me to say why don't you go and bother someone else because i for one can definately do without.
Your pretty sceptical about people posting about Honda minibikes on here which i find quite ironic and almost hypocritical considering you ride a Honda ATC. This leads me even more to belive that your posting bollocks like that purely in an attempt to impress a few people.
And sorry did you call me "love"?
