Screamin'Sheela Posted April 10, 2016 Report Posted April 10, 2016 So I thought I was Lean so I switched from 27.5 pilot 280 mains to a 30 pilot and 300 mains. I put new plugs in, ran a plug chop and the plugs look perfect! But if the engine is warm and I pull the choke while it's running, it increases in rpm. Not drastically but it's noticeable. What's the issue here? I played around with the airs crew and didn't see a change. Quote
tdod101 Posted April 10, 2016 Report Posted April 10, 2016 Are you riding with the choke pulled out? If so push it back in lol. I'm not sure what you're saying. Quote
Screamin'Sheela Posted April 10, 2016 Author Report Posted April 10, 2016 No I'm not riding with it on. Just checked it at idle. I changed my jetting recently and it is idling great, but if I pull the choke out while it is idling it idles higher than with the choke in. Quote
barry1me Posted April 10, 2016 Report Posted April 10, 2016 What he is saying is that when the bike is idling and warm if he turns the choke on the engine RPMs increase. Quote

barry1me Posted April 10, 2016 Report Posted April 10, 2016 Sheela you sound like a sped from your first post. Did you check and see how it idles when you put it in reverse? Quote
Screamin'Sheela Posted April 10, 2016 Author Report Posted April 10, 2016 I kin git'r up to 90 mph in reverse, no problem. Quote
trickedcarbine Posted April 11, 2016 Report Posted April 11, 2016 Little tube between the carbs is cracked. Or check the seal on the plunger. Quote
Screamin'Sheela Posted April 11, 2016 Author Report Posted April 11, 2016 Little tube between the carbs is cracked. Or check the seal on the plunger. I did notice that those tubes are pretty old, discolored, and frail. I'll replace the old lines and see if that fixes the problem. 1 Quote
bigweav81 Posted April 11, 2016 Report Posted April 11, 2016 I believe he's talking about your cross over tube. They connect between your carbs. sent from yo mammy house. Quote
Screamin'Sheela Posted April 11, 2016 Author Report Posted April 11, 2016 Ohhhh. I see. Is there any way to verify its the crossover tube other than doing a leak down test? 1 Quote
bigweav81 Posted April 11, 2016 Report Posted April 11, 2016 You can pull the cross over tube off, and inspect it........visually. sent from yo mammy house. Quote
hoppedupandcutdown Posted April 11, 2016 Report Posted April 11, 2016 Ohhhh. I see. Is there any way to verify its the crossover tube other than doing a leak down test? FYI, your carbs will be off during a leakdown test. 1 Quote
