dz06shee Posted July 21, 2008 Report Share Posted July 21, 2008 Hi guys Putting on some T5s soon but need an idea on jetting for them Done heaps of reading on the jetting section...kinda leaning towards a 300-320 main with NO lid and KnN filter and standard pilot or a 27.5 with needle still in center? Riding @ sea level with temperatures around 68 F - 88 F MAX Thanks. Quote Link to comment Share on other sites More sharing options...
Dinner Posted July 21, 2008 Report Share Posted July 21, 2008 Looks like you are in the right area. I would start with a 310 and go from there probably. Quote Link to comment Share on other sites More sharing options...

Yea will buy a few jets and do a couple plug chops, as for the pilot...should i start off with leaving the standard one? Quote Link to comment Share on other sites More sharing options...

dz06shee Posted July 21, 2008 Author Report Share Posted July 21, 2008 i run the same setup, t5 with open airbox w/k&n, sea level or close to it, summer tempsi run 280 main 3rd clip on toomey needle stock pilot 1.5 turns on air/fuel Im in Australia so dont really ever exceed sea level, its winter here at the moment so temps are @ around 18 - 25 C i would off thought 280 main is a bit lean with the lid OFF?

Michael Jackson Posted July 22, 2008 Report Share Posted July 22, 2008 (edited) no way, 280 isnt lean with the lid off, alot of people just run huge main jets for some reason,usually pipe companies recommend fat jetting to cover their asses i guess? i run a 300 in the fall and winter when it gets colder ps: theres a plug chop thread posted up top i think, people can only give you guesstimates , only you will know how your bike is running Edited July 22, 2008 by Michael Jackson Quote Link to comment Share on other sites More sharing options...

Toybreaker Posted July 22, 2008 Report Share Posted July 22, 2008 whats wrong with the toomey needles ?, i put them in when i got my pipes. I am running toomey needles in both of my shee's and your mate should lean it out a LOT. I run FMF's in my shee with 280 jets and for a bolt on bike it is quick as hell Shee'll be right Fair dinkum good luck on your jetting journey!

mdhc500 Posted July 22, 2008 Report Share Posted July 22, 2008 (edited) The best advice I got on here is jet one circuit at a time, and start off with jetting the mains and do plug chops. yes, it will cost you a few bucks in plugs but thats much better than the $$$ it will cost if you burn it up! When you do the WOT/plug chops you will get your mains jetted correctly, then as you notice the plug coloration after putting some time on them you can adjust your pilots as needed. I would keep your needle in the middle to start off being a sea level and start with the air screws out 1.5 or 2... Good luck and have fun!

dz06shee Posted August 1, 2008 Author Report Share Posted August 1, 2008 ok guys installed and jetted pipes.. 300 main needle on 4th clip and airscrews 1.5 out bikes starts nicely and takes off really well off idle... but it seems to be a bit laggy/groggy untill it hits power band...is this my jetting or the t5s? once on powerband it pulls nice Quote Link to comment Share on other sites More sharing options...

It sounds like you got your mains and idle screw good to go... And I would not guess based on what I have read what I have messed around with myself the needle being in the 3rd or 4th clip would cause that kind of lag/bog? Did you read the JettingFAQ document on the site here? It's helpful... A lot of the guys on here really know their stuff, but I think they ignore jetting threads... Try this if you have not already... http://www.dfn.com/benkaren/jetfaq.html Edited August 1, 2008 by mdhc500 Quote Link to comment Share on other sites More sharing options...
