That is good news petenz. Looks like i'd have to be revving the bejeus out of it :) I asked as, i had a high reviving issue whilst riding (seems to have come good now) And posted a pic of the bike just idling for about 3 minutes, and the header was glowing hot. WISH I HAD TEMP gun then!!!
This seems to have settled down as well now, as people i talked to seemed to indicate it was was just burning of crap in pipe??? As it had been sitting in shed for 3-4yrs before i bought it.
I have put on a massive 60kms to odo since buying it :)
I really do not know, other than last 4 times starting it, seems not to be this bad now. *phew* Best wishes Z

Not trying to bump thread. Just adding whats happening my end. Took bike for about 30min ride .... 23km actually. And freezing outside, 8c ... cold, but still love riding it. Got home, header was red hot again. I really do not like the look of the header pipe glowing. Concerns me. And not sure its right. hit it with the temp gun a few times , 146-156c....was the lower-upper reading. impressed that it cools down quite quickly though... hoping i am not doing any damage to it. newbs with a ttr250. :) z.

I have never noticed the header glowing before. 8c is pretty cool I dont think it should be that hot in winter. I don't let mine idle for long periods though. Maybe its jetted too lean?? How's the plug?
Put a new plug in about 80kms ago. Have not pulled it out since.
Another member (or two) suggested it may be running lean.
Will check it out and do a bit more research on it. I put the jets back to were they originally were set to.
i think there is a howto on carbs on the forum, think i better read this and get a basic understanding first.
Carbs confuse me :) but would be handy to learn abit about em, if i am going to make this bike a daily.

Bit of feedback.
My cousin dropped round this afternoon.
he has a mate, that works as a motocycle mechanic for a yamaha dealer.
He confirmed that hot header could be because of running lean, but also suggested something about value's not closing properly.
His recommendation was to rip the value cover off and check clearences, timing et al.
its all a bit double dutch to me. :)
He also recommends not riding it, unless i want to blow out a valve.
even my cousin whom has way more experience on bikes than me reckons it's getting to hot to quickly.
We let it idle for a few minutes, and he thinks something is not quite right.
Will wait and see what the mech finds out, and report back.
hopefully next couple weeks.

Hi again.
Just wanted to end the thread with some info.
Sorry i have been absent, have been travelling around.
4 months ago, had a yamaha tech, take a look at it.
I had it stored at my cousins place, so this is what i was told.
Values checked, fine.
Exhaust removed, and wire brushed out. Fine.
Carb, cleaned and air screw adjusted.
They could not get it running hot. Like i have shown in pics before.
So i am none the wiser. But being a new owner feel better that some one took a look at it.
I've been back, 2 months.... and ridden it 4 times, last time i rode it , i got a front puncture.
So waiting to fix this up. Have to say, that it does not appear to run as hot as what it did. (Air screw changed???)
Anyway just thought i'd update last post.
best wishes
Z.
