TE/TC TC150. Break in .

The at81s totally suck. I trashed them right after the third ride. Worst tire I've ever used personally

I'm hearing that comment a lot regarding the AT81's.

The front was awful. It wouldn't stay planted riding on flat ground much less tough terrain and cornering. Put me in the dirt and was very unpredictable. Got the irc ve front and rear. Thinking about the golden front next and maybe Sedona rear.

The AT 81's aren't a very good tire for where I ride. I took them off new and gave them away basicly.

Tried some more changes last Sunday , giving the JD jet kit a try and could only test in my back yard and I have to give it a thumbs up at this point. Was about 45 degrees out and went by the directions and did seam good. Will wait for better weather and will go with the yellow spring. Did swap out my rear tire to a Perrelli mt16 and will go to a Bridgestone m59 up front Really like this bike .

MT16 is a big tire on a 150, going to make it feel geared taller.

yeah but it's the King of New England. I don't think I've run anything but an MT16 on the back since about 1999.

Like the M59 up front as well.

Interested in hearing more about he JD kit and how it worked out when you take if for a test.

Great 150 reviews POURING in on all the forums! But I've not seen anyone try cutting the slide to help bring the jetting into line. Anyone? Anyone?

In this thread dartyppyt mentions it, he seems to have done more with tuning the TE150 Mikuni combo than most. http://www.cafehusky.com/threads/tc150-break-in.86143/

Yeah I took file to the stock slide. Think it was 5/32 file I will have to look. Only took a smidge off. Jetting at 30p 470main 2ndclip

Thanks for posting your setup. Can you tell me your elevation and temp range where you ride? Thanks

I've been an M59 fan for a long time, but I tried one on my Italian 144 and it just wasn't right. Can't put my finder on it, almost as if it was just too much tire. Too firm or too heavy or too controlling for the light bike? So I'm eager to hear how you like it on the 150.

Live in Virginia but ride\race from Florida to Indiana so 1800-200ft. Actually getting ready to go SC this weekend and temp 50-60 I'm running 32.5p 42needle 2ndclip 470main 50.1 VP fuel. When temp goes up above 70 have to make minor changes but wrote everything down last fall when temps were in 80s and just kept log. Also did some of the carb mods that Darin posted about. Definitely set your float height and drill the bowl nut. Carb base has 4 holes just need drill nut. This setup is for tight Enduro riding not screaming wot for 5 miles

Thanks for sharing. I'm just getting started on the journey of getting things sorted and all the good advice on this site is great. I've been following Darin's posts, he's a great source of info on this bike.

Sounds a lot like the places I ride. Mostly 500-2500 tight trails, occasionally 2500-5500+ more open trails.

Before my first real ride I knew it was pretty rich from riding in my back field at 150'. I put a 37.5 PJ in as that was the smallest that came with the bike. I now have down to 30 from JetsRus. Drilled the bowl nut and measured the float height at 7 mm. Didn't change it, should have, will do.

I finally got one ride in for a bit over an hour last weekend and will be testing leaner jetting as I get more chances to ride. It was about 40 degrees and stuttering some before clearing up pretty much across the band except wide open. That will only get worse as it gets warmer.

I'm running 50:1 with non ethanol super pump gas. What kind of VP fuel are you using and have you done any experimenting with the PV spring/setting?

I did some changing on P/V spring and ended up with the yellow.Get you a little pv tool makes turning p/v simple even out on side trail. I waited a little bit before i drilled out my airbox but would also recommend that little mod. really needs to breathe. i did mine under seat instead of in side number plate not that one way is better than other although i would say that the side holes probably draw a little more air. Both the p/v spring and open up for more air will affect jetting but once you get all set only minor adjustment will be needed for big temp/altitude changes. I hear good things about the blue spring and plan on trying it one day. I leave my yellow spring around 2-3 turns in from flush. You only need small 1/4 turns at a time it very touchy. Im running VP110.

Just a little foot note from Patriots back yard, a A rider in the area just kinda figured out his bike woes,he has a 2017 KTM 150xcw and he was going bonkers trying to get it running good and for kicks he borrowed a sx150 17 cdi- ignition box and he finaly has the bike the way he wants it.

What was he struggling with before the cdi change? Just curious what his issues were.

Ill try and find out,I know he 1st changed the pipe and was happy with that mod but still needed more and he has a friend with a 17 150 sx and for kicks he borrowed the sx box and he claimed that made the biggest improvement so he purchesed the sx cdi box,Im gonna a get him to follow this site for added ideas.
