Cleaning carb 1 Year, 9 Months ago  
I think I am going to have to clean the carb on my R*. When you give it any throttle it bogs down and tried to die. It will idle fine. I have been reading about cleaning the carb but have a question about removing the tps to take the carb off the bike. Is it ok to remove the tps or should it stay where it is?

Depends on how you are going to clean the carb. If you are going to dip it, it's best to remove the TPS.
WARNING: be SURE you know how to adjust the TPS before you remove it from the carb. If not, leave it connected and use spray cleaners and compressed air to do the cleaning.

I have no clue how to adjust the TPS. Last carbs I cleaned were on a Vmax 2 years ago. I now have an ultrasonic cleaner and was told it would be good for cleaning carbs.

Problem is that the TPS (electronic sensor) does not do well when SOAKED in anything. I would think you would be better served with a good carb cleaner spray. Leave TPS on carb. After carbs disassembly (all Plastic parts removed) put a small baggie or something like it over the TPS and tape to seal. Then have at it with the carb cleaner. Try to avoid spraying to much in the area of the butterfly with the TPS on the bottom to avoid it wicking into the TPS.

The carbs are not that complex on the inside so it should not be to difficult.

Re:Cleaning carb 1 Year, 9 Months ago  
Ok. Took the bike to my father in laws today. He has a garage and motorcycle jack so I can start working on this thing next weekend. It has a BAK on it but I think I am missing something. There is about an 1.5 to 2 inch gap between the BAK and the carb. Is there a rubber boot or something that goes there.

Should be a black tube from the BAK to the carb air intake

Re:Cleaning carb 1 Year, 9 Months ago  
people might be able to help more if they had some history of the bike.

Has it been sitting for a long time, ridden daily,,,,

If it has been running without the air cleaner (and if joint isn't there, then it probably has) it could be pretty gunked up.

Re:Cleaning carb 1 Year, 9 Months ago  
The history as I know it is as follows. I traded for the bike back in September 2015. When I got it, it would start and run but cut off when put it gear. Traced that to the neutral safety switch. The BAK was off of it when I got it and in a box of parts. Occasionally it would start leaking gas from the carb when I turned the key on and the fuel pump would run so I figured the float may be sticking. A quick tap on the carb would stop the leak.

Not sure how long it had been sitting when I got it, drained the old gas and put fresh in with some seafoam.

Don't remove the TPS. Remove all the other rubber parts, if you dip it, and leave the TPS part out of the dip.

Your right about the needle and seat sticking, being the cause of the fuel leaking. Tapping the carb is what gets recommended.

As mentioned, there should be a boot that connects the BAK, to the front of the carb.

I would recommend changing every o-ring in the carb. They can get very fragile after sitting for a long time.
Be sure and check the rubber on the main needle and the coast down ckt.
