Hi guys, takin on board the advice for the jvd 4 shoe clutch on the new go gxii for better fuel economy and a smoother drive, goin to use 2 gold and 2 green springs this weekend, should the springs be every second one on the clutch shoes or 2 green together and then 2 gold or does it matter? Shoes are all aluminium type

every other one, 2 gold should be across from eachother, and same for the green.

+1

That's how you get the long life on the clutch bearings with the 4 shoe.
As long as the two sets of spings that are directly opposite each are the same strength, and engage at the same tiime, your clutch bell will always remain centred and will never put side stress on the bearings.

If you find the 2 x gold springs and 2 x green springs with the alloy shoes is still a little much, try 2 x green springs with carbon shoes and 2 x gold springs with alloy shoes. This is a very smooth set up. Great for lightly dusty tracks or really slick surfaces.
The Ascendancy clutch ROCKS, and is a perfect match for the power band of the GXII-5RHO

I have a Go GX5R, serial number US0000084.

I read your post on the tech forum, about the long needle and short needle. However I was not sure what it meant.
You said that "if the needle stays in the receiver jet then...".. But what is the receiver jet?
Is the receiver jet the big giant hole you see when staring down the barrell of the carb?
Or is the receiver jet the tiny little nipple you see on the left hand side, where the needle goes into?
Because my needle exits this little nipple at about 50% throttle, and then at full throttle this needle is in the middle of the big giant hole in the barrell.

Does this mean I have the older carb with the shorter needle?

My engine has the orange cooling head with the lettering GX5-R, some stars, G-logo and some flames around it. Sticker on carb with G-logo. Yellow colored crank. Which gen. does it mean it is?

sounds like you have the short needle, the receiver jet is the hole that the needle tip goes into when letting off throttle. you dont have a older carb just the short needle, this engine is the 5.5 series GXR. if you live in U.S you can get the long needle here, makes for better runtime and smoother excelaration. all for the low price of 5.50

Hi guys,

just wanted to ask.... has issue (no biggie) setup

Losi 2.0
GO GX2
Losi clutch shoes/spring
2 alum / gold
2 comp / green
just like ... 2 alum / 1.0 and 2 composite / .9 on other clutch setup.

Anyway. engine still rolls when i remove finger on throttle. Remove the engine.. (check if clutch shoes rub on bell which can cause the clutch to engage early..) but i spin the bell and it spins forever...

I tried richening low end... same.. car still rolls. Also tried to lower the idle... car still rolls. I did lower the idle too much that cause to engine to die..

Local PRO racer suggest that the spings are too soft which causes the clutch to engage too early...

I haven't tried to remove the bell to check ... as i was having too much fun that day that i ignored it... did 6 tanks straight on this situation, and no ill effect.. hope not... i think it was bad for the engine at this condition..

many thanks for the help...

Whats the recommended or possible shimming options for a Go GX5R (not the II) running on 25% ?

after break in, 1 aluminum and 1 copper shim, before break in 1 aluminim and 2 copper.

Thanks

update on my "rolling" issue. Upon checking... 1 gold spring has lost tension. I can move the shoes back and forth 2 to 3 mm. I changed the "suspected" spring. Use the same shoes and also Losi Steel Flywheel and the issue is gone. Car/Engine was insane and i was driving "carefully". Joined local race sunday and was able to move to 1/4 finals, but drivetrain issue (actually my fault also, did not check).

thanks for all the help...
