Air filter could be dirty or very restrictive. try going down to a 70, or 68 jet.
the gpmx3 problem
so ive rebuilt my big bore engine with the 72. jet now,and started up first pull. now i have the airfilter hp and that works and all but i feel as though im bogging out alittle when i give it gas (runs a perfect tan color like that)but heres my question why when i take off the filter it runs better like i could give straight gas and 0 bogg occurs (but it runs lean )idk ive had this problem before so i figured bigger jet will solve it,it does in 1 way but creates a hole nother problem. rite now i have the stock carb on(and airfiler) wif dual filters but it still ant right i even tapered my neetle and the petcock mod.

yea that could be the reason ima see the difference
well that fixed the problem but now my screws for my head wont screw in i needs longer screws do u kno where i could get them
How long?? Are they M6 allen head / socket head??
yea i need etra longer screws and they gota be just alittle bigger so i would have a secure fit do u kno if i could just go to autozone or the old hardware store i need the screws like mexicos pic http://www.pocketbikeplanet.com/showthread.php?t=60901
hardware store is your best bet, they have hex screws of all kinds usually.
There M6 x 1.0 X how many mm long, you need atleast 80 to 90mm, get 8.8 grade 5 bolts, I like to see 3 or 4 threads out the bottom. I use SS flat and split lockwashers too.
bingo thanks for the help
I take a tapemeasure, mearsure the area where the bolts go add an extra 1/4" for threads out the bottom. Take that length to the store and find a metric M6 that long.
good thinkin
With 90mm long you will have room for washers if you want, my stock set are 80mm long. Might be hard to find at a hardware store. I sometimes have to go to a place that sells metal & bolts for something that long. Same w/ M5 bolts or 40mm long like for the stock Cag carb.
yeah because i cant find dese bolts no were
