Getting pissed because I've dumped a ton of time on my stuff and I can't get it quite right. Here is the rundown on what I have so far.
1.1p57qmj motor (stock internals) 2. 32mm CVK Carb 130 jet with performance manifold 3. 12 gram variator rollers 4. No rev limit CDI 5. Gates main drive belt 6. NGK Iridium plug 7. I swapped the final drive gear to because I was tached out and only achieved 45mph. I had full travel on the belt. 8. straight through exhaust 9.Stock Fuel pump 10. upgraded Variator from Monster GY6 11. Uni foam filter 12. eliminated all of the CARB items
So the problem is I can only achieve 7000 rpm at about 49mph. I'm 225lbs. It can spool out on the center stand. I'm not sure if I screwed up by using too big a carb or what. I have adjusted the valves and had some problems with ties which have since been flipped into some Dunlop 2CT's.
I can feel it start to bog on the throttle one it hit's the enricher valve on the CVK carb, and aside from that everything seems cool. Maybe not enough fuel with being a stock pump. I've had it about a year and just can't get it right now that I changed the rear main gears.

It's just a normal 150cc gy6 variator. It's from the stage 4 kit on MonsterGY6.com. BTW, you do not get the one pictured.

I think the most efficient way to spend that would have been to buy a bbk, Then a performance camshaft(They make a big difference.). Then up-jet the carb, and free flow filter/exhaust. Then *Experiment* with the variator weights. I've found heavier people need lighter weights. I would not recommend an Un-restricted cdi, unless it advances timing, because i've found that almost all stock dci's are not restricted. Waste of money if you ask me. I would HIGHLY recommend you getting the NGK boot cap for you Iridium plug. On every bike i've worked on it makes a big difference in spark reliability, and has made the bikes start easier.

Tell me what you really think and don't hold back. Oh yea, you did. Nice to know I'm "heavier" too. None of what you just said really helps me. Does anyone else have any ideas?

Wow, someones insecure about their weight. I really didn't mean t like that but ok. Of course non of what I said helps you because you read what you wanted too. I got a 50 that goes over 45, with $100, but you dropped 500 and can't achieve what my smaller engine can? I don't recall you paying for help, so you can lose the attitude.

I asked if my carb was too big? I asked if my jets were too much? You got close with your roller weight answer but your opinion of just buying a bbk kit in the first place and that I wasted my money wasn't very classy. My money is just that, mine. Just calm down smartass. You win, I just need some help.

Nycscooterparts.com sell high performance towels for you to cry into .
now did you just want to be a crybaby or did you want to get to 50 mph ?
some sites take your money others help you reach your goal .
What did you come here for ?

Uni foam filter12. eliminated all of the CARB items With the exception of the bolded items everything on your list either improves reliability of the engine (without adding any performance), or adds additional load to a stock engine (the upgraded gears). The 12g roller offer a very slight offset to the added engine load, but only under low speed conditions. I note also that you have not done anything with the contra-spring on the clutch. The contra-spring and rollers work in unison. Messing with one, and not the other is 'a job half done'. My first suggestion would be to step up to at least a 1500rpm contra spring (don't be surprised if you find you need to re-adjust which variator weights you use). EXPECT to be tearing your transmission apart several times to get it tuned in correctly for what you want, but bear in mind, that you haven't really done anything to make the engine put out more power. No bigger cam...no larger valves...no increased compression...nothing. To whit: A 1.0l, 3 cylinder Geo metro engine will not make a '72 Dodge Charger move as fast as a 318cid (5.2l) will, regardless of what gears you put in it or how long a stretch of road you let it have to 'get up to speed'. There is a point of diminishing returns when it comes to moments of energy available from a given engine, and you have exceeded that point by adding taller gears, but not increasing your engine output to match. The larger carb/intake/filter/exhaust might help a little, but putting an 800cfm Holley double-pumper on a stock Geo engine with a straight pipe isn't going to make the Geo engine suddenly put out 300HP. There's a saying amongst old-school wrenching types: "There's no replacement for displacement."

Just because you put a gear in does not mean anything , for all we know he could have replaced with the same = no difference . as far as the jetting and oversized carb I'm surprised he is not telling us about popping backfiring or bogging .

It does have the upgraded springs and the 1500 yellow main spring. I have plenty of power off the line it's just the top end that I'm not achieving. When I say top end, I'm not meaning top speed, but just the ability to tach out a little higher. I can hear it and feel it bogging like the a/f mixture is crap but I've toyed with this to no end. If there is a way to adjust the timing with what I have, it may fix it. I swear is too much air of too much fuel.
Also, if there are NCY golf towels I'm interested. Thanks guys

Bogging, yes in the higher rpm range. No backfiring at all. I adjusted the a/f mixture to eliminate any popping I heard originally. I put in the gear to get a little more top end speed. Before I was at 45mph at around 7500rpm. The engine has never seemed quite right. I switched from the 130 jet to a 140 for a minute and going big was not the answer. I'm now back at the 130 and thinking a 120 with 10g rollers

ok , so if you want to get more out of it , there are some things I need to know even if you have to take things apart to answer .
what is the gear you took out , what is the gear you installed ? what is the diameter of the variator ? what size belt is in there ?
your main jet it too big for a stock motor , put your stock carb back on go with a 38 to 40 pilot jet , check your main jet in your stock carb if its 107 use a 110 . Show me your muffler pic or link .
