slanktapper Posted August 30, 2016 Report Share Posted August 30, 2016 I haven't been able to find any info for these and I'm wondering if it's even worth the $$ to have the honed/bored to clear out that rust. Thanks for your time Quote Link to comment Share on other sites More sharing options...

trickedcarbine Posted August 30, 2016 Report Share Posted August 30, 2016 Hello oddball exhaust port.... Don't stress over the residual rust in the ports. Tends to happen on alky bikes. Especially if they're not purged. Get some photos from different angles. Just seeing that exhaust port, I'd assume they are some type of drag port. 1 Quote Link to comment Share on other sites More sharing options...
RIPPIN' IT UP Posted August 30, 2016 Report Share Posted August 30, 2016 Ring life gonna be pretty short with that wider exhaust port, still worth doing if in good condition though & it's what your looking for.

sheerider11 Posted August 30, 2016 Report Share Posted August 30, 2016 That's an old school eyebrow type of deal. I already talked to Sleeper06 about that a few years ago. Nothing new there. 1 Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted August 30, 2016 Report Share Posted August 30, 2016 I've see portiing like that a few times, it can be improved on with a lil feathering out and shaping . Rippen,as long as you shape the port correctly width hasn't ever been an issue , actually not wide enouph is a bigger issue on a single ex port engine because there's not enouph time/area to expel the charge before the transfers open. 1 Quote Link to comment Share on other sites More sharing options...
slanktapper Posted August 30, 2016 Author Report Share Posted August 30, 2016 Here's more pictures, I will be primarily trail riding with some dune ripping. Was it a mistake picking up these cylinders? Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted August 30, 2016 Report Share Posted August 30, 2016 Not at all. You can control it with pipe choice honestly. If it's a little much you can try a different pipe. You can change domes too. I'd say send them off, get em inspected, get some timings, maybe a builder can give you a pretty good setup for what you want.

If you want more you can change out the pipes. Until your on the question for power it won't be an issue 1 Quote Link to comment Share on other sites More sharing options...
slanktapper Posted August 31, 2016 Author Report Share Posted August 31, 2016 Trying to sell? Sent from my iPhone using Tapatalk Probably not no, but I'm going to bring both the stock and ported ones down a highly recommended mechanic. If i don't end up going with these do you want me to PM you? Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted August 31, 2016 Report Share Posted August 31, 2016 (edited) If they are drag ported Id probably sell them and get something that is dune ported if your doing trails. Nothing like having no low end due to a drag ported cylinder. Then putting a pipe on it that kills the top end to try to get some low and mid range.

bigweav81 Posted September 1, 2016 Report Share Posted September 1, 2016 There's a method to measure from tops of ports to deck, and you would know your port timing. Hard to say by looking. Some guys put some wild shapes on ports. I couldn't see the ridges inside the exhaust port being beneficial, but that shape could be fixed. Let the curious know how they run, if you run them.
