Re: 72cc Stock Setup Concerns

Well I stripped the motor down and thoroughly cleaned every surface that should be sealed. Put it back together and the only time I have temp problems is half throttle. Max at WOT for like 3 miles is 380 and that is firm. As soon as I go half throttle the temps will jump higher, at one point it went...

Re: Summer Build: '96 SA50

I am pretty sure it is a small airleak that is opened up at higher temps. At idle I couldn't find a leak with the carb cleaner. The temps really take off around 250 so I am pretty sure thats when the leak opens up. I just took it apart and am cleaning everything and putting it back together this wee...

Re: 72cc Stock Setup Concerns

Just the gas line is leaking. This didn't happen the 5 times I took the carb off before but now it happens when I have an air leak too, just more problems. If it is just leaking through the gas line then it should be fine right? Just not shutting off which shouldn't hurt my mixture as the float will...

Re: 72cc Stock Setup Concerns

So I couldn't find a leak with the carb cleaner but when I took the carb off to upjet, the fuel line didn't stop flowing. Could this be a vacuum problem at the petcock or in the vacuum line causing me to lean out? Didnt get a chance to look at the plug after WOT yet, but after I got back from my rid...

Re: 72cc Stock Setup Concerns

Sprayed carb cleaner on it at every possible place for a leak and nothing. I did have to turn the air screw out another quarter turn but that would just make my idle leaner. Could it be possible i just need a 94 jet? Temps only climb above 380 when I let off the throttle after doing WOT for over a m...

Re: 72cc Stock Setup Concerns

I know how to punch out the tab in the airbox. I am saying i also took out that extra tab on the airbox cover by the inlet.

Re: 72cc Stock Setup Concerns

Stock airbox, tight on there with a good oiled filter. Not over-reving, if anything under-reving. Needle in rich position (only has 3 notches). Mainm is 92 and it did make a big difference going from 90 to 92 so maybe i should try 94 before jumping to any conclusion? And if i am correct the a/f has ...

Re: 72cc Stock Setup Concerns

Yeah that was my concern. Can i rent a leak down tester? I know i can go and rent a compression tester but that will only tell me if if I potentially have a leak, not where one is.

Re: 72cc Stock Setup Concerns

Will lighter weights increase my max rpm? it is currently only around 8.3k. Max temps with the 92 after WOT for like 2 miles into the wind I got 392 after coasting into my driveway. So i think i should go to a 94. If i could make the needle richer i would too seeing as cruising at 35-40 put my temps...

Re: 72cc Stock Setup Concerns

Sounds like i should pick up some 7g rollers Rode it in to work today `5.5 miles and got 50.8 after going WOT for 30ish seconds. Temps were 320 cruising at 3/4 throttle and 362 max. The rmps are pretty low which is probably why I am not seeing more from WOT and why you suggested the lighter weights?...

Re: 72cc Stock Setup Concerns

I picked up the malossi from g9 when he had the sale, when did i say I had the polini? Maybe I did, i might be losing it haha :crazy: And took it for its first more than half throttle run and the temps were too high, 385 and climbing when I slowed down. I got 50.6mph but it didn't feel like WOT gave...

72cc Stock Setup Concerns

I want to go with a stock setup with my 72cc cast iron malossi kit but I am concerned, The a/f screw is exactly one full turn out and the rpms vary by almost 700 between when it is idling from cold and warm. Will the stock setup have enough tune-ability in it for me to squeeze out 55ish or is it rea...

Re: Summer Build: '96 SA50

So i was running it a bit today and i went WOT for a few seconds but it didn't seem to be generating that much more power. Is this an effect of my rich main jet? I pulled the spark plug and it look decent but did have some gas/oil on the threads. What do you guys think, should I go down to 88 or kee...
