Chigga , To be honest im happy with the way its running at the moment so i wont be changing anything in the near future . And i dont think ill get that much more out of the bike . If you buy a powerbomb on the net from the USA you will pay about half the price compared with the shops here , i was quoted $399 here and had one delivered from the states to my front door for $219 ?? .. Getting my suspension done was what got me going a lot quicker than any header pipe ever would ? just a thought ?? ..
