mcman56 Posted February 18, 2009 Report Share Posted February 18, 2009 I have had to drill my own pilot jets for the TLR200. If I remember correctly, the #40 is .4 mm or 0.0157". A 1/64 drill is 0.0156" and a #78 drill is 0.016". You can get small drill sets at: http://www.mcmaster.com/#31055a64/=npars I did once see a link for carb parts that suggested the #40 jet from some year CB750 would fit but never tried that one. The TLR200 main jets are the same as XR100 mains but the pilots are different. Quote Link to comment Share on other sites More sharing options...
stevec Posted February 18, 2009 Report Share Posted February 18, 2009 They're hard to come by. This guy has them but hold onto your wallet! www.motorcyclecarbs.com You're better off drilling... It helps with the off-idle stumble but doesn't cure it completely. Quote Link to comment Share on other sites More sharing options...

If so, PM me with your address and I'll send you a big bunch of #38's free so you can drill them and experiment without worrying about making a mistake. I have a lot of them for some unknown reason in my jet boxes and never use them. Jon Quote Link to comment Share on other sites More sharing options...

alan Posted March 7, 2009 Report Share Posted March 7, 2009 Had the same problem on my cub, had to have the air screw out 2 turns further than the best idle setting to get rid of the off idle stutter. I drilled out the jet using the mini drill set below.. http://www.rdgtools.co.uk/acatalog/DRILL_SETS.html I took the jet out to 0.4 and then 0.45, now ticks over with the screw 2.5 half turns out and no stutter.. fixed for less than a fiver and 1/2 an hours work.
