I like the Dellorto,s and clones of Dello,s the best for the street on most scoots.
Small, easy to tune, parts are all over, Prices start at like $40 for the clones. They work good. Just remember to stick with one jet manufacturer. They all are different as you have already seen. For example Naraku,s 80 main for the Dello is about like a 90main genuine Dello jet. They are all ok to use, just stick with one brand when tuning one machine or you will be all over the place.

Ok, jetting is ok now, going to open it up a little more in the am. New thing now, once the pipe hits and tge revs climb, I run the carb empty. So do I just wait for a bigger carb, or will bypassing the vaccum petcock help. I was flying the first time it happened, scared the shit outta me, thought I blew it up. had to suck on the vac line to refill the carb. fine again till the revs hit a certain point, as long as I dont let ut wind out, uts fine, but if I try to peg it, it runs dry.

You can bypass it temp with no problem. At least you found the problem and its any easy fix. I plan on replacing mine with a manual shut off also. I plan to mount it on the rear of the frame and hide it under a body panel. So I can still reach it but no one can see it. Not much of an anti-theft device. But every little bit helps.

Oulled Frankie out on the porch this am, started her, and had to kill it real quick. Something just did mot sound healthy. Of course I heard ping bing waaaah, but there was an odd clank bang in there too. Shit. Pulled the head, nothing loose in the cylinder, so now I am realy scared. I removed the jug, everything seemed ok. Now I am thinking that I was hearing things, that I'm just paranoid. I was putting it back together, and I figured it out. Small end bearing. I looked at it, turning it in my fingers, and one of the damn needles fell out. Alright, it was brand new when I started, so it either was a factory dud, or I killed it with lean conditions. I have a few here, so I swaped in the.best one I had.
I am going to bypass the vac shtuff, once that is done, I am going to cut a hole in my cvt cover, to see if my belt is sinking into my rear pulley before the clutch catches. If it does, what could I do to remedy that situation?

So I ordered the shut off that John linked to, it and an inline filter. Should get those in a couple of weeks. Well I bypassed the petcock anyway, and ran it straight, using vice grips as a shutoff. Last night it was running fine, except for running the bowl empty, today it is trying to soft sieze. I am at my wits end with. this thing. When I took the petcock out, I forgot to close off the vac barb on the carb, I only rembered cuz I saw the cap on the bench, the bike did not run any different with open vaccum leak. What the hell does that mean? I checked the seals, no oil, the cases are dry around the sealing surface, no leaks around the reed block, but it did not make a bit of difference to run it without the vac line sealed. I blocked it off and tried aggain, but to no effect. One run it shows and acts lean, the next its acting fine. WTF?  ?!@!!!!!! |

I have tried every jet from 80-115 nothing works. Up to 100 is lean, 105 up is so rich the plug is wet. It wont even frie with a 120, just washes the plug.
I can not tune this pipe. I am at a loss. I love the pipe, but my motor seems to hate it. I just cant figure this out.
Gotta rest on this project a day or two, the wife is getting fed up with me spending more time and money on the bike than any other project I have going. I have used twenty bux worth of ( 7 ) plugs, 8's like 2 strokd said. I bought a jet set another twenty, the pipe, the seals the bearings, the gaskets etc,.... shes pretty pissed I still cant ride it.
I will get back to it in a few days. In the mean time I am going to weld the stock pipe and see, hopefully it works, I can tune ut for that, then try this TG again.IDK. I am just at my end with this thing atm.

I am going to cut a hole in my cvt cover, to see if my belt is sinking into my rear pulley before the clutch catches. If it does, what could I do to remedy that situation? Softer clutch springs or free up the belt in the front pulley with spacing/filing. A case leak will make them act really screwy. Could still be something with fuel delivery. Float height. |

I am beginning to think I have an invisible leak, behind the stator. I will check tomorrow am, while the wife is in bed. I checked, and recheckef the float height, and the case seal, and everything else.:banghead:

Well, as I said, the wifes pretty pissed,  and my newest idea did not fix that. As drastic as it may seem, I am about to pull the motor, and split the cases again. :doh: I cant grasp this. Unless it leaks after it warms up, I do not expect to find anything. But, it makes a strange sense, everything is rine, till it warms up. Now, this is not the first time I have seen that happen. Oh, another thing, if you all were to run your bike with an open vac line, wouldnt it run like shit? I only ask cuz having the line open did not effect mine yesterday.  Also, my symptoms seem to mirror those of another member who did have a leak. Well, now to let the wife know what I'm up to. This should be great. I cant wait to see her reaction, to me spending more time working on the bike.  |

Before I spkit the cases, I am going to try a stock replacement carb, with my jets, who knows.

Fabbing up a crude leak tester would save tons of un needed work!Cap intake and exhaust ports and maybe use a bicycle pump to get 6psi in there and see if and where its leaking...

Found three pin hole leaks, one in the case seal, that opened after the engine was warmed, a seal, and tge f-ing head gasket, again. Split the cases, again. I noticed I alread can detect free play in the crank bearings. So, going to change the bearings, and re seal the cases, and look for my stock head, so I can ditch the damn o ring gasket!
The case would only leak when it was warm, the seal was leaking around the crank, and the o ring blew right above the ex port.
Since photobucket is still being a pita, can I email some pics t you, 90GTVert, to post here. This is pointless without pics. Sorry.
Thanx for the tips and thanx for reading the rantings of an insane redneck.

Your not insane just "special"....well thats what my mom used to tell me when i was feeling down. I had to split my cases again the first time i tried. Because when i got done tightenings the bolts i noticed that one of the guides had fallen out.... I was like  |
