pilot jet ?

[400exridin121]

Everyone on here says a 42 pilot, but sparks recomends 45. Which is better? Im at 900 altitude, and have a sparks x-4. The sparks jet kit has a 45 in it and its only 15$ vs. 45$ for dynojet what should i go for?

Is the Sparks X-4 a slip on pipe im not sure if it is? If it is then I would go with a 42 cus a 45 is way to rich for a slip on , if it's a full system and if you have a bored motor running a higher comp then use the 45. With a fully modded motor i've heard people running 50 pilots.

[400exridin121]

no its a full system , and its not bored or anything but it will have a uni to but other than that thats all

I would go with a 42 cus I still think that 45 would be alittle rich for your setup but the only way to find out is buy both and try it. Pilots are only like $4 or $5 a peice.

Where are they that cheap? everywhere ive seen are $40

[Honda#4]

I ment Mains sorry gotta think before I type. Yea I haven't seem them cheaper than that. But try the 42 pilot first.

ok thanks im goin to get a 42 pilot and a 155 main and one other main what should i get? It will be for summer

[Honda#4]

155 might be too small for for a full exhaust like you have so get a 160 main that will make you close during summer , you'll have to adjust your air/fuel screw in a bit but that's all.

Have fun

[400exridin121]

Alright thanks alot im goin to get 155 and 160 just becuase its 9 to ship under $10 and $8 over so its pretty much free
