1986-88 1TX overheating

[Pat Conlon]

Rereading that cam timing thread brought back old memories, both good and bad.

Yes, that was a tough time for you David. However, you pulled through like the kick ass Texan you are.
We are most fortunate to have you with us.

I did a conversion for your oil temp. 120°C = 248°F. During the summer and riding in my area, the temps easily get to be 95-105°F and the oil temp will often reach 124°C/255°F while sitting in traffic. I have been told by Randy and Robert that these high temps are ok. The Legends racecars often run 127°C/260°F while at WOT on the track. I personally would say things are ok on the 1TX.

Agreed.  Randy had some concerns over the oil temps on the race bike - concerned they weren't high enough!

I'm thinking the 3CV May have an issue with running too cool ...

Cam timing modification: I did ask this question 11 years ago, here's the post:

Speaking of cam timing....Alf, have you verified that your current cam timing is correct?
Sometimes the cam chain can stretch and get the cam timing off....

Cam chain, guides and tensioner are new

As far as I know and like Randy has written in another post, 90-115ºC is the optimum oil temperature range

Alf, I am a novice MC enthusiast, (please educate me), however, temp described are chart extreme, but still in range. if in range FINE.
Even 10% out, FINE. As long as the out of range is not too far for too long, so what?
When our bikes were QC checked they ran them from start to red-line then shut down. The bikes didn't even get to temp on start.
The ranges are just a warranty range for service. the bikes will do fine a bit either side for not too long.
I doubt Darko's bike in Croatia (1.3mil km) has run factory temps its whole life

This is what i meant

This is the ad i saw, on FJowners whilst not being distracted........

The one on the right seems to be running a bit colder than the one on the left!

Troyskie: Thanks for your coments... and the pic 
If I dont own my 3CV I will be not worried... well, not sure. In fact my friend Mingo´s 86-88 run always at the same temperature side to side with my 3cv
His settings: restricted cans (like OE), all STD in carbs except Dynojet needles (yes, with STD mains) and KN filter in OE box

Consider that I´m speaking of extreme ridings. The rest of the time, between 5-10ºC hotter than my 3CV, but ok. In traffic, both dont get 120ºC. This summer, travelling in Andalucia with 45ºC hot, no traffic, secundary order but fast roads (120-160), my 3CV was running at 98-100ºC, better that myself

And yes, I think that I´m going to adopt the Danko solution: no oil temperature gauge
