ohhhh he rides the hell out of it! i think that is the main issue... i have had to tear this sucker down and rebuild the whole thing! but now it runs like a RAPE APE!!! and he rides it like he stole it... hell since i have not charged him anything he practlicly has! i am going to stick a monster oil cooler on it... slap in some 60 weight and see what happens!

 

Rear cylinder turns off ? Please explain

 

Serious engineering mistake there. Hell my lawn mower holds more than 2 Qts. of oil. That electric fan that someone posted here would be like taking a squirt gun to a forest fire and an oil cooler would be of little or no help. Rear cylinder is probably shutting down due to the nose cone area getting so hot it's messing with the ignition. That 110" polished motor needs some oil, more like 3-1/2 qts at a minimum. Like someone mentioned on an earlier post, make sure that sucker is jetted properly as well.

 

You do need to get more oil in that bike. a oil cooloer with heavier oil will work but you will have the same problem as you are having now. Also check the jetting and and the fuel air mixture screw to the carb for adjustments. If the bike is lean if will run hot. I think that is correct. My chopper was doing something simular and the card was out of adjustment. I strongly suggest bigger oil bag with minimal 3.5 quarts or more.

 

Tell me then, how will this work ?

 

Jagg oil cooler or maybe even twin oil coolers would help alot.

 

that thing really needs more oil capacity, and a cooler as well. Tell me, if you run half the amount of oil, how quickly does it get dirty and break down, especially when it's running hot? doesn't sound good for longevity of the motor, but that's just my take on it

 

Pull the plugs and see what they look like.If the bike is running Okay,no sneezing,or popping through the carb.There could also be a timing issue.Very hard to diagnose over the airwaves.Good Luck.

 

ooh there is def an issue... i keep getting coughing though the carb...playing wiht the dials and jets on it to get it dialed in and cooled down a bit

 

You could try running a long oil filter.I use a 5 1/2" ......that thing holds almost a quart by itself.
Def running lean.Sounds like the rear cylinder module on the ignition is crapping out due to excessive heat.Once they start going they don't get any better....
