sheefreak Posted December 24, 2006 Report Posted December 24, 2006 What are you running for pilots and what clip on the needle? Quote
CadillacBanshee Posted December 24, 2006 Report Posted December 24, 2006 What has been done to the bike since last time it worked fine? Quote
twojztt Posted December 24, 2006 Author Report Posted December 24, 2006 What are you running for pilots and what clip on the needle? i do not now what pilots came pre jetted clip is on third groove with two more to go down. Quote
twojztt Posted December 24, 2006 Author Report Posted December 24, 2006 What has been done to the bike since last time it worked fine? stage 5 port work 34mm carbs intake manifolds 19 cc domes the base gasket is a .20 vitos gasket which would cause the slightly lower compression in both cylinders?

locogato11283 Posted December 25, 2006 Report Posted December 25, 2006 sounds like your jetting is off. if you got the carbs "prejetted" thats your problem. you cant rely on that to work. every engine will have slightly different jetting, even if they are setup identically.. you need to see what jets are in those carbs..

Machwon Posted December 25, 2006 Report Posted December 25, 2006 150 psi would not be uncommon with that set up. You should be running race fuel though. Here where I run 34 pj's on a similar set up. 155 mains CGM middle notch, C series needles will be the better choices. 55 pilots 60 slides. Quote
Karzy5150 Posted December 25, 2006 Report Posted December 25, 2006 I would have to agree with everyone else its probably your jetting what do your plugs look like? Quote

Here where I run 34 pj's on a similar set up. 155 mains CGM middle notch, C series needles will be the better choices. 55 pilots 60 slides. i am running race fuel,but would like more compression,is there a need for 17cc domes or 18cc Quote
Bansh-eman Posted December 25, 2006 Report Posted December 25, 2006 if you want more compression then yea you need smaller domes... but with your mods 150 isnt bad... why exactly do you want more compression? the gains are minimal versue the money you spend on the gas... right now you can run 50/50 and be perfect and you wont see really any gains by going to stright race gas..

Bansh-eman Posted December 25, 2006 Report Posted December 25, 2006 if the bike does not pop or bog top end arent the main jets correct? not necissarly, only way to check your jetting is pulling your plugs and reading them... 2 strokes arnt like 4 strokes you cant do your jetting by popping or backfireing...

Bansh-eman Posted December 25, 2006 Report Posted December 25, 2006 how many turns out are your air screws? your mains sound rich.... they should be like a brown paper bag after ridig for a while... Quote
jbooker82 Posted December 25, 2006 Report Posted December 25, 2006 Get you a pair of CEK Needles. Those really helped my banshee out when I ran Keihin PJ 34mm Carbs Quote
