I have been one of the admins that has run one of the XT660 forums for the past 15 years, this XT forum will be closing December 2019 & all the information will be lost for ever, I have collected 15 years of modifications done to the XTX XTR & XTZ 660's & put them all in one place in an English PDF mod book.
This PDF download will be sent via eBay message service after payment with a download link these downloads are best saved to a PC not a phone, please check you eBay messages to recieve the downloads, I will also include all the PCV & PCIII fuel maps I have in my collection which range in just about every engine mods known to these 660's, you will not receive anything via postage only electronic download which will be sent within 24hrs after payment. The PDF via download only: The complete book has over 680 pages of pictorial information with detailed information on curtain subjects. I have tried to add as much information in areas where the information was available. All the mods have actually been carried out with proven results. All permissions were granted from the XT660 co m to produce this Modification Index. Feel free to ask any questions
