Sinlge 35mm jetting ?'s

[jmd0346]

Hey guys. I just finished a rebuild for a friend of mine and now it needs some tuning. He's got FMF pipes, Trinity 35mm single, Vito's power pistons, stock porting.

 

The bike has never been right since he bought it.

 

The jets are 50pilot, needle third clip, 175 main. It runs way too rich on the pilot and possibly the needle. It does rev out pretty clean once it gets going but the main may be a little rich as well.

 

 

 

I know what it needs Im just not sure of a good starting point for the pilot.

 

 

Any suggestions? Thanks guys.

Try a 46, but it shouldn't be any more than a 48. 50 is pretty rich for those mods. Main may be a little rich, but it should be close. Only way to know is to do a plug chop. Leave the needle on the 3rd clip, I'd also recommend a dek or eek needle.

Thanks differentstrokes. Thats around the size I was thinking. Yeah we are gonna go do some chops on both our bikes pretty soon. Ill also try those needles.

 

 

I wonder how those needles would work on my setup?

The only way to know is try I guess, what needles are stock in yours? Maybe DGK? I think you can get the needles for about $9 a piece from most places. The DEK and EEK are really close, I'd run whatever I could get easier. Try sudko or carb parts warehouse, they'll give you some good tech info. JMO
