The Zongshen TT 250 is Coming - Page 72

Don't passup the option of drilling out a jet. A set of small "wire gauge" drill bits can do wonders. You can use the non-cutting end to size the current jet, and then drill it out with the next size up. Often you can drill them by spinning the drill bit in your fingers. Of course you cannot go smaller. Also any time I do this, I take a file and make a mark through the number so I know that jet has been modded.

Did you just get main jets or slow as well? the slow jets they have pictured look different than the slow jet in the TT. I am curious what the replacements for these are as well

You can go smaller by soldering the hole shut then redrilling. The softer solder may wear over time but it lasts for years.

just the main

Well crap. ordered in February...and waited and waited. Being super patient. Never called or emailed them once.
Got my delivery notice.....this Saturday between 10-12. One would think that this would be the perfect delivery day and time. Not at work, early enough to get to play with it all day...but no.
We've had a trip planned to go to Nevada and see some friends for 4 months. So, my neighbor will accept the delivery. Man....I really wanted to be there for Santa!

Same here. Ordered a few different smaller main jets. I'm jetting for elevation (8,000 - 11,000 ft.). So far, all I've done is adjust the clip on the needle one notch to run a little leaner which seemed to help. Will try another notch and see how it goes.

Who needs a slow jet if you're at WOT all the time?

So won't be changing that one at least for now.

Oh no! What timing! That's unfortunate. At least it'll be waiting for you when you get back, right?

Hello all, picked up my TT at the terminal myself on the evening of the 21st as the delivery to my place was to be today and I just could not deal with it sitting 70 miles away all alone. The packaging looked intact so they forked it into my pickup and off I went. After removing the cardboard, the bike looked great but the two outside stringers on the pallet were snapped and the 2x4 used to stop the front wheel was completely knocked away and loose. The bike was pushed forward and the tip of the front fender had poked a small hole in the cardboard that I did not notice on pickup. CSC does a really good job of strapping the bike down to the pallet so I did not think the bike was hurt. This is what may have happened: The breaks were at the fork cut-out points near the rear of the bike. My fork lift driver picked the pallet from the rear, not from the side where the fork cut-out points are. This type of pick may have caused the breakage since the weight of the bike was far forward of the pick point. There is not adequate structure for the forks at the ends of the pallet like there is at the sides. Upon picking from the end the pallet may have snapped and the front dropped causing the bike to push forward hard and remove the 2x4 front wheel stop. Those straps really held the bike down like a seat belt. I don't know, CSC may want to write with a red sharpie "DO NOT PICK FROM ENDS" on the cardboad. After getting the bike on the ground and giving it a look I was really impressed. This is my 5th bike and my 3rd new (2 cal guzzis', a cx500x, and a suzi gs500f). Is the fit and finish like that of a new guzzi? No. But it is really good for $1,900 and it started right up. Then it quit. I forgot about the fuel petcock! Doh! The headlight and the plate light did not work. Perfect. It really is. One of the reasons I bought this thing was to learn how to work on it, so lets go. Put a couple K on it, put it and me to bed. Next morn I fixed the headlight. All I did was plug it in. Like a lamp. Then it worked. Hey, this motorcycle fix-it thing is easy! Since I had the headlight off, I fiddled with the brake line/cabling routing. I also disconnected the speedo cable and squirted some lube in it. The plate light was different. I could not figure out how to get to the bulb so I left it alone and went for a ride. Starts and idles nice. No problem with shifting or finding neutral. Brakes terrible on the first ride but get better quick. As the kilos grew, I started hearing an odd noise or rattle. It seemed like it was more apparent when dropping the throttle back and slowing on engine compression. I did isolate it to the engine as I shut it down several times going down a long hill and the noises quit. Must be something loose and rattling so I tightened up all the fasteners. Some of the body fasteners needed a little tightening. The only slightly loose ones on the engine were at the exhaust pipe connection. Looking around there I found some stuff that looked like toasted sand under the exhaust connection, laying on the engine. I thought this stuff was being blasted through a bad connection there and possibly causing the noises. The 2 nuts at the flange needed to be tightened. They were not finger loose but did need to be tightened up. I went for a ride and no change. Rats. What ya gonna do? Wash and wax! After a few more rides though, I think this problem is going away. I'm not getting the toasted sand stuff residue as much and on my last ride I did not hear it as much. Maybe the flange gasket was not seated correctely. I should disconnect the exhaust and see what things look like. Don't want to do that untill I get a new gasket. I'll call CSC and ask; maybe they will send me one. And the plate light decided to work on its own. I live in the south puget sound area of Washington and am about a 25 min. ride from the logging roads of the Olympics. If you see a black TT there it might be me, stop and say hi.

Hey, just remember that riding is like machine work: slow is smooth. Smooth is fast.

Yah, ain't it though? The good part is, we'll be staying at a hotel in Carson City after the gathering at our friends, a mere two hours from home. Mrs. 2LZ doesn't know it yet but I'll kick her out of bed at 6:00am and we'll be on the road early Sunday morning. I'll be cool and bring her a travel pillow! ;-)
Home by 9 or so. That should work..... Then I have all day Sunday to uncrate and play.

Drilling alters the angles around the hole and usually leaves the hole rougher than original, both of which can actually yield less flow. If the jet is flat on both sides around the hole then drilling, as long as the hole is perfectly smooth, will increase flow predictably. If you decide to try be careful to keep the hole smooth and straight, might not be easy. If it acts funny keep in mind that you might have reduced flow and don't let it confuse you on your path of tuning.

Just finalized my order with Ryan at CSC today! It's too bad that I don't have the time to pick up my bike until next Saturday :(
