Bike cuts out at higher RPMs

I have a problem that is pretty frustrating and I was hoping someone might have a solution.

I bought a 2006 Classic (my first bike) a few months ago and it already had a hypercharger and V&H short shots on it. However, the owner who did those mods didn't rejet. When I bought the bike it was running fine but wasn't taking advantage of the mods.

Recently I had a problem where the bike would idle OK, but as soon as I gave it some gas it would lose power and sounded like a lawnmower. I figured then would be a good time to rejet, so I did it according to the instructions:

- 3.5 turns on PMS screws
- adjustable needle to 5th position
- changed main jets to suggested size
- zip tied the vent hose forward under the petcock
- did carb sync

The float bowls were really gummed up and I cleaned them out. I also put in a can of Seafoam to try and clear things up.

Now the bike runs great most of the time, but occasionally at higher RPMs it will either stall completely or it will go back to sounding like a lawnmower and have very little power. This will happen for about 5 minutes or so, then it will go back to running well. It was scary because it completely stalled out on the freeway once.

I'm going to go back in and try to clean the jets more but is there anything else that I can try? Any help would be greatly appreciated!

It sounds like you did a good job - but, did you adjust the float? You will use more gas now and at high RPM you may be running ouy of gas - Check floats specs and adjust

Yamaha 650 v star tps,.. how do i find it on a 2004...then how do I test it to see if its the problem??

I would still think this is a carb issue. Most techs stink at properly rebuilding carbs because there are so many different kinds.

I however have spent 15 years honing my carb skills to perfection.

If the bike was purchased from a person at a higher altitude, main jet size might be incorrect. Or if it has modifications to the exhaust or intake - also main jet.

Contaminated or old fuel could also be a factor - have you drained the tank?

The TPS has to be set and checked with an olm meter. The TPS controls the CDI second timing curve which may have failed. I have seen this many times!

Sounds like rev limiter at half throttle ttr90

I have just worked on a 2003 ttr90 for a friend and had a similar problem. when I got the bike it had set up for a few years so the fuel system was wrecked. after a thorough cleaning the bike would run fine up to about 3500rpm. then it would cut out much like a rev limiter. it was very consistant and I read some forums but none said anything about a rev limiter. I had also installed a carb kit. I decided to remove the carb and try again. I figured it was lacking fuel in the upper rpms so I raised the throttle cylinder needle as high as it would go. there are 3 notches to set it. the factory setting was in the middle. after I raised the needle it ran like new and turned through the rpm range perfectly. hope this helps someone.

I have 2006 TTR-250 with nomods and only 200 miles on it. Like another owner, I have problems running except on choke and have seen the pipe glowing red at idle. The bike has always been hard starting. ...

Well the glowing red header pipe and the fact that its hard to start is a pretty good sighn that your VALVES need adjusted.on a four stroke bike you have to adjust the valves about every 6 months to a year( and more often if you run it at high RPMs alot) i have both 2-strokes and 4-strokes bikes and have had this same problem with my 4-strokes(honda&yamaha) if you get a manuel and are somewhat mechanicaly inclined you can adjust them your self but if your not, i would take it in and have it done because if not done properly its easy to bend or break a valve( and i think yours has 4 valves.2-intake and 2-exhaust) And head work is not cheep!!!! but a adjustment on the valves is!!!!! good luck....

Rpms speed up faster then bike does. Sounds like clutch slip.

You can adjust it by slackening the cable...unless it has hydraulic operation....Otherwise get it replaced before you do more damage..ie clutch dust and debris in the oil, so dont forget the oil and filter change too.

Will not rev over 8000 rpm

This is hard to tell without riding it to feel the condition. Here are a few things that come to my mind.

1 Spark plugs or ignition system not able to handle the higher demands of the higher RPMs

2 battery or charging system not creating enough power to meet the higher demands of the bike (ignition and fuel systems)

3 Fuel flow to the carbs is low or the main jet is clogged.

4 valve adjustment and or valve timing
