BBoy69 Posted May 5, 2018 Report Share Posted May 5, 2018 May be a dumb question but is it absolutely necessary to bore and hone your cylinder if your just replacing your pistons? Top end isn’t bad but just feel safe replacing on a new quad Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

Any time you change your rings you should hone the cylinder so they seat properly. Otherwise you're throwing power (and money) down the drain. If the cylinder is out of round or ring end gap/piston clearance out of spec no point in doing a hone, send them off to be bored. Quote Link to comment Share on other sites More sharing options...

97Screamer Posted May 5, 2018 Report Share Posted May 5, 2018 If you're going to get new cylinder soon anyway save the money on the pistons and just buy the new setup now. Why put new pistons in cylinders you are going to replace soon?Thanks for the respond like I said top end isn’t bad but I think I’m going to buy so new oem cylinders anyway to send off to hjr cam or macdaddy haven’t decided yet done wanna be waiting months for just a port job Sent from my iPhone using TapatalkSent from my HTC One M9 using Tapatalk Quote Link to comment Share on other sites More sharing options...

97Screamer Posted May 6, 2018 Report Share Posted May 6, 2018 A little over $200 bucks? Too much? Sent from my iPhone using TapatalkYeah probably. They are decent carbs imo but a pain to setup. Pwk is much preferred around here. I'm seen PJ sell as cheap as $75 and as much as $200.Sent from my HTC One M9 using Tapatalk Quote Link to comment Share on other sites More sharing options...

If you ordered those exact carbs cancel your order. Search on here for Keihin PJ and Keihin PWK, lots of information on it.Sent from my HTC One M9 using Tapatalk Quote Link to comment Share on other sites More sharing options...

I would tear down my bike at the end of the season and check the bores for size and roundness, if they were still in spec and I could hone them clean I would re-ring it. Its possible to just re-ring it, or change the pistons and rings "correctly" Quote Link to comment Share on other sites More sharing options...
