i have a black clutch spring but i cant find any info on it. what can you tell me about it? is it good?

also i just fixed the hole in my gearcase and can i use a regular 5w30 oil in it or 10w40

 

Primary Spring right?
Is it by chance Black with a white stripe? or black with an orange stripe? both of those are Dalton industries products and can be found at http://www.daltonindustries.com/atv/atvsprings.htm. If you mean secondary springs... maybe a Hot Seat model? idk if they have one... www.hotseatperformance.com Hope that helps. (BTW Black/white is ok for a 4-stroke, but i dunno about a 2-stroke... if that's what you got...)

 

black and white is about 140 shift out so its to low for an aaen pipe.

Bolaris has a black spring. 45-75 I have not heard of anyone running it.
