the other morning my brothers TS50 wouldn’t start, when we tried to bump it the back wheel locked up so we assumed the piston had seized. on stripping down the engine we discovered that the cylinder and exhaust was full of fuel. what could cause this and how can we prevent it. please help if you can thanks paul
yes it was a stuck carburettor float/needle valve

1978 gs550 only on the left side i am going to cut the rotten area out and weld in a patch but somebody told me you cant certify it if i do that? please help?
They might think you messed with the muffler. Fix it and then wrap your pipe in header wrap.

most obvious would be a crankcase that got over filled

Yes. That appears to be exactly what’s for sale. A quick glance elsewhere reveals that this is high for an aftermarket bracket. A fancier looking Diamond Powersports bracket is $35 at Kneedraggers vs this at ~$50.
So are you asking something
or just spamming the forum?

You could always measure it yourself.

exhaust i have does not have o2 sensor bungs
You can order O2 sensor fittings and have them welded onto another set of pipes. It will also depend on what year the other system is off of. If you change the exhaust, you can get away without remapping the ijection, but if you add an air cleaner of any type, you HAVE to have the injection remapped….I would HIGHLY recommend the Screamin Eagle Super Tuner PROPERLY set-up on a dyno.
Obviously "lil thumper" doesn’t know jack about HD’s….you CAN NOT disconnect O2 sensors on you bike!!!….IT IS FUEL INJECTED not carbed….so…IT IS NOT POSSIBLE TO REJET IT!!!!……also, 07-08 bikes, Power Commander does make an O2 sensor eliminator, but it is not possible to eliminate them on 09-up. Not only that, you don’t want to eliminate them!!!……the O2 sensors are there to help with performance and fuel economy when running in closed-loop mode during steady cruising speed. THEY ARE THERE FOR A REASON!!!!!
ALSO…..STRAIGHT pipes are the WORST thing you can add to your bike!!! Straight pipes WILL cause a loss in power!!!….you will lose about 15-20% of your mid-range hp & torque…..this is the rpm range in which you spen MOST of your riding time and wehre you NEED the power the most!!!
Lil Thumper obviously doesn’t know much…..If he doesn’t know these simple FACTS, I highly doubt he a actually building choppers, if he is, I feel SORRY for anyone who buys one.
EDIT: I stand corrected…..SHE doesn’t know much!!!
By the way, 42yo, riding since 4, first HD at 16. first NEW HD at 18, working on them since 19 (professionally since 22) with numerous ground-up builds including 2 Best-Of-Show winners

I have a Harley Davidson Road King classic 2001 that it has Magneti-Marelli FI. Only mods. are screaming eagle slip on mufflers, Arlen Ness big sucker2 air cleaner kit, and Arlen Ness big shot fuel tuner. I programed the tuner, seems to run best on the preset map settings already loaded. However, when I accelerate hard then let off and let motor idle down, every so often the exhaust pops. It is a loud pop, not the normal kackle. It is not a cough or sneeze through the breather. What could be causing this? I have tried the program in several modes but they all do this. Have also tried less fuel. I do not have an exhaust leek.
ACTUALLY…….exhaust backfire on decel can be caused by lean OR rich!!!!….USUALLY on injection, it’s caused by rich (too much gas at 0% throttle position) , carbs by rich also ( high manifold vacuum pulling too much fuel through the idle ports), although, too lean can cause this also (lean mis-fire leading to raw fuel through the exhaust that get ignited by internal pipe heat and cold air from exhaust reversion hitting each other), it has alot to to with the total engine combination, exhaust length and diameter and cam overlap and igniton timing.
I don’t mean to sound insulting, but you WASTED your money on the Ness Fuel controller, you SHOULD have gotten a Power Commander….ALWAYS go with products from a campany that SPECIALIZES in what they sell!!!….Power Commander III USB with Acellerator Pump Feature is the industry standard (for almost everything except HD Delphi, PC 5 with wide band O2 sensors for Delphi), even better, is HD’s Super Tuner (for the newer Delphi System). With a Power Commander and a DYNO, you can dial in the injection PERFECTLY….with your situation, lean out the air/fuel ratio at 0% throttle from 1000-3000 rpm (approx, each engine is individual).
The best thing I can tell you to try is to lean out the LOW RANGE one step at a time until the exhausti popping stops. If it won’t stop by leaning it out, you may have the rare case of actually being too lean as Adam said, try richening one step at a time….but I will lay odds on the fact that you are actually rich….HD’s Super Tuner has a feature to lean out the a/f ratio at an already predetermined rpm range and throttle position, on the Power Commander, you have to manually change each cell of the map individually.
ALSO….EXTREMELY IMPORTANT!!!!……..
In order for ANY adjustments to be CORRECT, you will HAVE to verify not only no exhuast leaks( as you state you don’t have), you MUST verify no INTAKE leaks…AND….you MUST have the THROTTLE POSITION SENSOR "ZEROED"!!!!!!!……unfortunately HD is the best place for the TPS….they can do it in a matter of a few minutes….it REQUIRES special equipment.

or a after market exhaust that might fit?
Not sure but I think Super Trap and/or FMF should at least have a free flowing replacement muffler for your bike. You may have to re-jet your carb especially if you also change your air filter.

does anyone know if vance and hines exhaust would fit on an 08 blast. the latest they have confirmed would be an 04 i called vance and hines yesterday and they didnt know hd still made blasts.
i don’t think that buell has changed the blast at all, so i’m confident 04 setups would still fit…. probably more an epa type reason
