Tri-z hard idle help.

[TimSr]

Rigaman, Spectro is fine, and has been around forever. Probably a good choice if thats how it was setup by previous owner. I would recommend not running it any richer than 40:1, and a 12oz bottle to 5 gals is probably better, and easier to measure/mix. Thats what it was designed for. It doesn't burn off as qucikly as conventional oils, and will accumulate to excess in the crank if you run too much of it. ( A light pooling of 1 or 2mm oil in the crank is desireable)

TriZ exhausts always leak, and the negative effects are limited to cosmetics. Hi Temp silicon in conjunction with your metal gasket will help, but is usually not long lasting.

Your max overborer at 70mm will also be pretty insignificant to your carburetion. As I said in another thread, TriZ factory jetting is very rich, and once you get things stabilized and consistant, and are ready to fine tune if you decide to, you'll likely end up smaller than stock on your main.

Awesome! Thanks for the help. As long as its not gonna hurt the motor, the exhaust isn't anything for me to worry about. I think 40:1 is a good ratio. My buddy ran 50:1 and blew his motor fast.

I set my air screw to 1 3/4 and it was better.

I wish I was closer to ohio. You guys gave a lot of cool stuff going on down there.

so I found out the bolts that secure the intake boot and reed cage to the head were very loose. Air was just sucking in the engine, and it finally wouldnt start at all. It must have been the reason for the rough idle. As time went on, they shook out more, and finally it just wouldnt start.

I have kicked it over so many times today after tightening the intake bolts. It will putter a little, but nothing. It will puff smoke, and want to start, but it seems like it isnt getting the gas it needs

So I looked up about priming the fuel pump, and maybe filling up my carb with gas so I can get it going. I put a new plug in, and it has good spark.. So must be fuel.

I dont seem to have a long fuel tank breather tube. It is there, but it only runs under the rear fender up to the rear master cylinder. I cant blow into it to get fuel into the carb like some people say to do.

What is my best solution to this? I am pretty sure this is why it wont start. Nothing else has changed.

[Rigaman]

I just cant get it started. Fuel pump seems good. I primed the carb by using a bottle and a fuel line and pouring pre mix in through the carb. kicked it over and over, and nothing. I checked the fuel line where the petcock connects to the carb, and it was bone dry. I tipped the bike and gas poured out. I checked the petcock, and it is good.

I even sprayed started fluid onto the air filter, and tried.. nothing. Putters, but it wont start.

Could my Reeds be the problem?

Anyone have any ideas? I pulled the carb, and it looks clean. But I havent had time to really check the float and jets yet.

[RiJiD-WILL]

take your carb off and check your jets also check the diaphragm in the fuel pump. write the jet sizes down when you check the carb but I dont think thats where your problem is.

was there fuel going to the carb from the pump? was there any fuel going into the crank case from the fuel pump?
it sounds like you might have burned up the rings by having a lean condition from your loose intake boot letting air in...

can you check the compression?

[Rigaman]

It feels like it has good compression when I kick it. I will have to do a test.

I didnt ride alot with the air leak. I never had i wide open either. I had it half revs and didnt go too long. After my last ride it started up the next day. Then a couple days after it wouldnt start. So its weird. If I fried the rings it would have been while riding. My carb doesnt seem like its geting fuel. I pulled the fuel line off the carb, and it was dry. Bone dry. I dont think there is any fuel going into the crank case either. I pulled the line off the crank case and it was dry.

I know my petcock is ok. The fuel pump works cause when I tipped the bike after I unplugged the line there was fuel in it. I pulled off the petcock, and it had fuel in the line too.

I pulled my carb, and the float bowl was full. I didnt check the float or jets yet. The air cleaner is pretty dirty. It wasnt on fully tight, so crap could be in the carb. But I doubt it. I bet its the rings.

I hadnt even really broken it in yet. It was a fresh rebuild. So that sucks

[Rigaman]

What kind of numbers should I be looking for in compression?

its got a 70mm piston. If I fried the rings, Will I be ok just putting a new set of rings in, or will I have to re bore? If I have to re bore, I will need a new sleeve.

It shouldnt be that bad. I barely rode it. I never had it opened up either. I babied it cause the fresh top end.
