Hey, thanks for the info. I do have a 135 main and 130 secondary from a set of TT carbs. As far as I can tell the XT and TT carbs are the same except for the jetting. I put XT jets in and am running the air box. Since I have the zeel, no over rev.

You will need the adjustable slide needles from the tt carb. The xt's do not have the clip slots. Try it with the side off the air box. This setup needs lots of air. The stock box was the restriction in getting the top end power. I have only gone to 6800 ft. That is the highest point on the east cost. It is about an hour from me. It will be way too rich for 10,000 ft. THUMPTHUMP

I think one set of of the two carb sets I got was from a TT as it was jetted 135 main and 130 secondary. I did not know about the adjustable needle differences. Makes sense since it was for street use and the adjustable jet had the brass plug as well.

Any outward sign of a TT carb? I have both sets installed now but do not know which set was what I think was TT carbs.

Steve

TT carb has a manual choke lever and the xt carb uses a cable to the handle bars. The tt has adjustable needles , the xt does not. The TT usually comes with 135/135 main jets and the xt usually has 125/130 main jets. The rest is the same. The pilot jets vary from 46 to 48 depending on the year. THUMPTHUMP

My ignition box with the 86 curve for my 90 xt600e came in today. I plugged it in and it runs. I am off tomorrow and will see how it does with all the extra advance. I did a top speed run a couple weeks ago and will try it again at the same place. THUMPTHUMP

:thumbup1::thumbup1:

anxious to hear your results...

I'm hoping it works, I have a "e" motor that'll be getting this option , soon. 28deg advance is pretty anemic .

Well, I went riding in the mountains today and put about 200 miles on it. The improvement over the stock ignition is very noticeable. The throttle response is much better, the power down low is better , the transition through the middle got rid of the flat spot were the second carb comes in, and finally a surge of power on top to the rev limiter instead of flattening out. It revs out much quicker and you have to shift quick to stay off the rev limiter. It gets to 100 mph much sooner than before and is held there due to gearing and the rev limiter. Over all a great success. The only strange thing so far is it runs for about 2 seconds after you hit the kill switch before it dies. It does die immediately when the key is switched off. The idle was much faster than before I changed it out with the stock one and had to turn it down a little. I rode at altitude most of the day 3000-4500 feet and had good improvement , but when I headed home down to about 1000 ft it went much faster with more air. If anyone is interested let me know and I will tell you who to contact there to get this done. I have already sent him the map for the 86 that was loaded into mine. THUMPTHUMP

I am happy your were able to use the 86 curve and have such good results. HPI will probably sell lots of those TCI's with that advance curve in it.

I think the reason the zeeltronic works so well is that you do get the actual 36 degrees of advance you program. Who knows what the OEM and aftermarket analog CDI's actually advance to.

Good show....

Steve

The Oem and aftermarket are digital for these bikes (TCI, not cdi) , the stock is 28deg advance, probably aftermarket copied that limit(unless they take a motor apart for each model, they don't know if it can take more ). The one he bought is from HPI . As you know, Zeeltronic doesn't make one for these models.

Yep, I read that earlier that he needed an advance curve for the earlier models to send to HPI.

I don't think Borut is going to bother building one for the TCI since there is already a digital version out there.

I am happy he could use the 36 degree curve to good use. I guess they did not move the trigger coils so that allows for full advance

Why wouldn't he make the newer one? Multiple sources is what keeps prices down. There is a lot of the "e" models out there, just not in the states. :censored:

PM sent. THANKS once again:clap::clap:

I have repeatedly asked Borut about it and last conversation he said it would not pay him to do it. I'll bump him again, especially since the older advance curve really wakes up the bikes. Many might convert to get the boost.
