Hey. I does sound like valves are out of specifications. Does your bike start normally? If valves are out, you should hear it right away.

01 yamaha r1 overheating at idle on hot day, but fans are working?

Hi, Anonymous and the usual suspects are:
1. Low coolant level.
2. Restricted radiator air flow.
3. Faulty thermostat.
4. Coolant pump or fans inoperative.
5. Vent hose crimped.
6. Air in the coolant and needs bleeding.
7. Engine idling too long or bike moving too slow.

I have a 2000 Yamaha R1 that has problems starting. a friend looked at it and feels its the timing. I put a new battery, new starting relay, new starter and had a tune up done to it. when the bike gets...

The thing about electronic ignition is the setting cannot change, as there is no points to wear down and alter the timing.
with the exception of the flywheel key breaking or the cam timing jumping teeth, both highly unlikely occurances, as it wouldnt run cold with either of these

hard to start when hot can be flooding or too rich , or possibly an electrical problem, but if it starts cold OK and runs fine, doesnt cut out or misfire as it gets hot, and the only problem is hard hot start. then fuel mixture is likely.
If it will push\roll start when hot, this may eliminate ignition problems.
recheck the valve clearances.
Make sure the air filter is new.
I also find that some moreys upper cylnder lube in the fuel can help, but cant explain why

I have a Kawasaki Ninja, ZX6r, 1997 F3. The bike starts great and rev's great when standing. At high rev's its as sweet as a nut. The problem seems to be when riding the bike and the revs are below 4,000....

There are adjustments on carbs for low speed air intake (air mixture screw)find out factory settings and reset that mixture.Sounds to me like those adjustments are out of sink.If so the bike will run very bad from idle to about 1/4 throttle then run great from there up to full throttle.this definitly sounds like carb problem.

My 2003 yamaha yz450f will not start when it is hot. Why? What is the compression supossed to be? Could jetting cause the problem. It will start and idle when cold, but once it gets warm/hot it will not...

OK a cold starting YZ
yes you have nailed one cause but is unlikely if runs well until you switch off then cant restart but if you don't even get to ride for a while then I would not necesarily be re jeting but cleaning the jets and or replacing same size jets would be great place to start
the most common issue or maintenance is valve clearances and although they should not need to be adjusted to often they give you awefull starting problems if they are out of spec
and being the age of the bike I would consider getting leak down test done to varify the vales are in good shape and sealing well
Compression test of any use on your bike would be impossible as the auto decompression would hinder any results but if you could get past that issue then anything over 200 psi is good and will run fine on less but we all want the best so aim high I say

2001 harley fatboy caugh and pops back through throttle body when cold. runs find when hot.

If you try to ride the bike or rev the engine up while it's cold, this is normal. Most engines will do this because the mixture is lean for a cold engine. When you start the engine, allow the engine to warm until it goes into the slower idle speed.

Good Luck

'02 Yamaha XJR1300 Rattle/vibrating noise from bottom of engine

how do you adjust the headlight beam on a xjr1300 naked 2002 bike, is it as simple as undoing the 2 bracket bolts at the sides of the lights and re-setting the lights to a new level ??
currently it seems to be set for riding with a pillion passanger or heavy load at the rear as the lights are set low, no one flashes me even if i ride at night with full beam on !

thanks xjr cambs

2001 twin carb R1 i had smoke coming from under the seat

Sounds like the rectifier has gone bad, overcharging the battery and cooking wires. Your best bet here is to take it to a dealer rather than risking putting in new parts then frying them the first time you ride the bike again.
