After about 15 months of hard work, liasing with the Managing Director of Yamaha Motors (Uk) Ltd, they have finally given us a slot in their website under the owner's club http://www.yamaha-motor.co.uk/yamaha_spiri...bs_overview.jsp

Ok boys & girls we finally have the fuelling fix for sale on ebay and also the maintenance manual for the bike at the following links http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...A%3AIT&rd=1 http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...E%3AIT&rd=1 we gave away 4 of these free to 4 lucky testers to try it and report and here are some of the comments from these people Thanks to all the testers for their help on testing my mod. The test results are back after one month & this is what the testers had to say. Can be bought at Ebay. http://search.ebay.com.au/search/sea...satitle=xt660x .................................................. .................................................. .................................................. .................................................. ..... Hi Kev, How are you? I was late on carry out the mod cause I wanted to replace my ECU first. It was replace about a week ago. Yesterday I carry out the "Fuelling mod". The small black box mod with the resistors. When I finished, I went for a ride. I was impressed Kev. The bike was very smooth. When I close the throttle very little surging. Generally surging is much more less than before. Very nice Kev......very nice. My initial C01 was -8. I adjusted it to 15. I will experiment about this more. What do you think? I have now on the bike the STD air filter. But I will put the K&N filter again. What C01 will I set? Also I think that acceleration is better now. THANK YOU FOR EVERYTHING KEV, Laksof. .................................................. .................................................. .................................................. .................................................. .... Re: Mod Stuff -------------------------------------------------------------------------------- Well, I've had a busy afternoon. I've drilled holes in the air box and fitted the covers as per your instructions, removed the snorkel and adjusted the CO as well. I've also fitted the variable resistors and I'm pleased to announce that the bike still starts, so I'm fairly sure that I cut the correct wires and managed to solder them together correctly, hurrah! I've adjusted the air temp and the coolant temp as per your instructions and had a quick trip out to see whether the bike still goes. The most noticeable difference is that the bike is a lot smoother when coming on and off the throttle, this is a big bonus as I commute into central London for work and as you can guess that involves a lot of on/off throttle riding. The surging at small throttle openings is improved as well although not as dramatically. I will do some more fine tuning at a later date so there may be further improvements to come Fitting the kit was fairly easy, although I don't have a great deal of mechanical know how a methodical approach seemed to pay dividends. On the whole I feel that fitting the mod has improved the bike and wasn't to tough to fit. I would guess that it took me about 4 hours to do the whole job as I wasn't rushing. Thanks for the kit Kev I'm sure I'll be in touch as I'm not entirely sure how I tell whether the bike is running too lean or too rich. Is checking the colour of the plug the best method? Anyway hope you had a good run out and are taking a well earned rest. Thanks Skeeter .................................................. .................................................. .................................................. .................................................. ..............

Improvement in performance, acceleration.

TOTAL SCORE = 9/10. get this marketed gents! I think there'll be some money to be made if you can get the audiance Recommended improvements to this mod. Pictures with the instructions are a must. i had to print them out myself..which was a bit of a pain as i dont own a printer! Did this mod meet your expectations. I was unsure what to expect if im honest..but a good surprise. Alot less surge and it makes the bike alot easier to ride full stop. Thank you Tomr

Most bikes are still experiencing low revs surging but we have a mechanic on our forum who works with r+d in VolksWagen he knows a thing or two about fuel injection and engines and he has designed a small mod that can be found in my forum if anyone is interested go to XT660.com and look for the Kev Mod. here http://www.xt660.com/showthread.php?t=194 Thanks

If anyone has a problem with the fuelling please visit www.XT660.com, we have an inexpensive fix that once you have registered (free) can be found here: http://www.xt660.com/showthread.php?t=194 Regards

Hello Mate, well JMC is my best friend however he had a change of heart, sold his bike for an Aprilia Tuono then suddenly decided to move to OZ and as a parting gift he handed down the domain and forum to me. So now I am running it with my usual trusted friends Buck / Cool4blade and a few more to come.

This is to inform everyone of a specific forum dedicated to the Yamaha XT660X & R, the forum is run by myself and other veteran XT660 oweners who have an intense knowledge of all issues regarding these bikes, issues such as mainentance, avalability of parts / deals and we have own sponsored companies offering discount to our forum members. Any problems with this bike like the usual surging / ecu / tps have all been overcome and we have now a specialist mechanic on board who has patented the Kev Mod which helps regulate the current by use of capacitor inserted in the wiring to the ecu / fuelling sensor hence making the cut -off problems history. The forum can be found at www.xt660.com, come and join us and see for yourselves. CaptMoto @ www.XT660.com
