I got an 88r pretty much stock with white bros air filter, paul turner type 6 ppe and silencer, bored 1mm over, boyeseen reeds. I just rebuilt and was running fine before I put airbox lid and snorkel on. Now it misses high in rpms. Do you all know what size jet I should have with specifications as above.

i don't know the size you need, but if it was running fine before you put the lid on, you need to go down on the mainjet.

Yeah I would like to get an extimate though because I dont want to buy the whole kit. It has a 155 in it now

Seems like they had a 145 or so in them stock. If it ran fine before just leave the lid off. It will make more power that way anyway.
