g16 governor adjustment/speed spring ??

[bigfoot216]

I am looking to get a little more speed out of my 97 yamaha g16. I have read on hear that you can turn the 10 mm screw in and gain speed. I have done this , used up all the threads, and I did gain quit a bit of speed. From about 12 mph to about 17mph. My question is, will this hurt the motor running it at wot?
Also, I have looked into the speed spring and was wondering if anyone has done this same setting ( replacing the speed spring and turning the 10 mm nut all the way in.

I have done a search but can't find a definitive answer.

Thanks,
Scott.

I am not one to give advice on here as I am in learning process myself BUT
I did a few minor things to my 99 G-16 and it runs Perrrfect :

Changed Oil to Mobil 1
Took Clutch apart - Cleaned & Torque Spring Installed w/Spacer
Cleaned & Re-Jet Carb (BIG DIFFERENCE IN PERFORMANCE)
Tight 10mm nut ALMOST (not all) to complete tension with Speed Spring Installed
Re-aligned steering

This minus the tight bolts etc : The plus with the help of all the great people on here I have an excellent cart, it runs 24 MPH & Climbs almost straight without streaming
but for everyday use it is smooth & quiet

To answer your question I do notice a bit quicker response with Speed Spring

Thanks,
I will be ordering the speed spring soon.

I pulled the body off today and while that is at the body shop getting a fresh coat of paint, I will be addressing some minor rust issues. I will post some pics as soon as I figure out how, lol. looks like I need a photo bucket account.

Did you use a K&N filter and new exhaust??? What size jet did you go with???

I have all the other mods you have done... so just curious

Bigfoot, you might not need to run the 10mm nut all the way in depending on how fast you want to go. Are you running stock size tires or larger? I'm assuming your still stock. I did the same stuff Indian did except for the carb. I have 22" tires, torque spring, speed spring and about 1" left on my 10mm nut and I run 27mph on the gps all day long with no issues. Personally, I feel the speed spring is the best $20 you can spend on this board and keep your cart relatively stock and safe (from blowing up!).

[bigfoot216]

Yes I am still stock. I have the body stripped off and getting it painted today. I am ordering the speed spring today as well. I plan on doing the rest of the hop ups, lift, tires, clutch kit, re-jet carb, over the winter.

Bigfoot as I stated do not turn back all the way and luvthemud also said

Don't thread 10mm all the way back, you will compact spring all the way and also put more tension on throttle cable.
Leave the inch (or a few turns fwrd) the speed result is the same.

I used the Yamaha stock/performance jet from CPP
I keep stock air filter clean - As I said I am happy with my carts performance!

i like the K&N filter with a sock.got it from CPP.carb. breathes with less restriction.my .02 cents.
