grubee 66cc with cns v3 carb help

[snopro1379]

okay so i just got the 2011 grubee kit with the better carb a few days ago. Have it all put together and was running pretty dogish with the break in mixture. Now after breaking it in i am running klotz super techplate at 32:1 based off what i been reading. I also changed the plug to the E3.12. It definitly runs a little better , but as the hotter the motor gets (more i ride) the "doggier" it gets. I really would like to ride it to work which is about 5 miles but there is some pretty good hill that i would like to be able to pull.

I was hoping someone could help me on the following based off what i have read on this helpful forum:

Can i remove the head gasket and just run like the black or copper gasket maker? I want the motor to be reliable but just looking for it to clean up and make a little more power.

Also i have a msd 8mm spark plug wire which i read will help. Is this something fairly easy to replace. I have all the crimping tooling from when i built my hot rod.

also: the intake looks to be a little rough, and with being a manager of a large fab shop i have access to all kinds of dy grinders etc. Will it help me to clean the intake up or even lengthen it if i have to? i can easily do this but dont want to butch it up and go the wrong way with it.

i kinda like the exhaust. Its somewhat loud but not obnoxious. I want it fairly quiet.

Any other easy tips, or tricks would be greatly appreciated as i am new to the world of bike motors.

Thanks, Dylan Myers

and by the way i already loc tited everything on the motor as it almost fell apart in 5 miles. haha

maybe some carb work?

I always clean up the intake and the exhaust, trying to match the flange openings of each to its respective port as close as possible. On one I also had to clean up the ports in the cylinder also. You will need to put about 250 to 300 miles on the engine before the power starts to increase, at least that's what it took for both of mine. A word of caution, when die grinding the cylinder do not open up the port or grind near the bore because the chrome is very thin and can be damaged very easy.

sounds good,

the more i ride it the better it seems to get

thanks again

can anyone help me out on the spark plug wire issue? can i change it with the stock spark box? reading alot that it will help.

i also am going to extend my intake tube and lengthen my exhaust which should help some too

 

[Greg58]

Yes you can change the wire, it screws out of the cdi just like the cap screws off. Some are hard to get out but do come apart. Since you are talking about lengthening the intake and exhaust you may have already found the link below, if not it has a lot of useful info.

yep found that link and that is my basic guideline as of now.

over the week i took out the head gasket flattened the headsurface to seal well and sealed it up. I also took notice my E3 3.12 plug is slightly shorter than stock so i took the washer off of it and now they are very close. Just from doing this i recieved a ton more bottom end power. When i pulled my plug it was pretty black and oily, of which i already thought it would look like that since i had a feeling it was rich. I will wait till i lengthen the intake and exhaust before i play with that...........
correct me if i am wrong.......

from that link i am reading that adding 6" to exhaust is best?
and that lengthening the intake 3-4" is best?

im looking for good bottom end but also some top end too.....

thanks

On my bike I used a 13 inch head pipe on the exhaust a home made muffler and flange. It helped the low to mid range greatly, helped top end also. I have not worked with the intake yet.

welp, finally got it running pretty good and took it on bout a 10 mile ride. Almost back and it seems like the clutch locked up...motor turns over from flywheel but the gear that turns the chain is locked? idk what to do help!!!

You have two bearings and a large spring on the output shaft, the shaft will come out without splitting the case.
