You're welcome Greg... that is the best place and prices I have found on bits and all else for my rotary tool, I get my deburring bits and all my drum sanding stuff crom them also, good stuff at great prices, its the stuff I use to do all my port work on my jugs and. Anything else that needs to be ground down or sanded that needs a small tool for the job.
I have never been able to get by with stock jet in the NT carbs down here where the air is hot and thin alot, I can with the RT/ Dellorto Clones for some reason but a #70 bit is always the size of the jet in my NT carbs and I solder and redrill to either #72 or #73 before I get that good plug chop and the 4 stroking is limited to low speed low load riding.
I finally got that expansion pipe running satisfactory on the Kulana, it will cruise at 42 mph now and its not crazy loud doing it, my other pipe got me an additional 3 mph but it was way to loud to ride into town, the pipe I speak of is one I picked up off ebay for $10+$11 shipping best I remember, about $21-22 total, I feel bad because someone here on the forum pointed me to it and it slips my mind now who it was, I bought one off amazon.com too, but I think the one off ebay might be a little better... im no sure but Im gonna try the other one on another bike and see how it does.
But even with the little bit of extra restriction my carb tune is still working fine, I thought I might have to jet down one notch but didn't.
