Have an 07 sportster I just put a 1250 kit on and a PC-V tuner. I downloaded map provided to me by power commander guys and it runs okay but after only about 10 minutes of riding me engine temp shows 309. Checked oil temp and it's at 180. I plan on getting it dyno tuned but I don't want to melt it down before I get the chance to get it done. Are these numbers something to worry about or not? Temp right now is 90 degrees and 60% humidity

 

When I got my power vision the tune that was installed by dyno jet had way too much timing & was causing my bike to run crappy. I got my 1250 kit from hammer & contacted them. They sent me a tune & my bike rode excellent from that point on. You might want to have whoever kit you got look at the tune your using before you damage your pistons.

 

Thanks for the insight. I will do that. I got a hammer kit as well. Would you be willing to maybe send me a picture of you maps? My tune from power commander doesn't have any changes made to the timing portion of it. Just the fuel

 

10 minites is not enough to get it warmed up. Normal head temps on a stock sportster will go over 400F.

Running it that short without warming it up is only going to cause condensation to not burn off.

Run it for 50 miles and then check your temps, if they are over 420 then you are getting over normal and only then you need to start worrying.

 

Thank you a ton. I figured it wasn't too much to worry about but wanted to make sure before I let it get much warmer. On the oil temp what would be a temp that I need to start worrying? Just wanting to make sure I keep a close eye on it because I was planning on taking about a 200 mile ride this weekend and was going to cancel if I thought I was going to have any issues

 

Ad DB said, normal head temp reading on a Sporty is 400* +- 20*

Oil temps will vary, but on a hot day, riding hard, don't be surprised (or worried) to see it in the 230-240* area. Others may be more tolerant, but if I see the oil temp (in the oil bag) going above 250*, I would be looking to install an oil cooler.

btw, I wouldn't put it on the dyno til you have that 1250 broken in.

 

400 holy sht I had no idea

 

Thanks for all the input on this. Really put my mind at ease

 

345* is the temp before my tts will allow any recorded data iirc. The placement of the sensor makes for a misinterpreted temp. Follow advice above especially Kevin saying to get a good break in before getting a dyno tune. Remember if you have the pv you can do it yourself without a dyno if you got time and patience.

 

when I installed my 1250 kit (also did big valves and cams) the bike ran hotter than normal for the first hundred miles or so...I chalked it up to everything being tight and new..now that it is broken in it is cooler...and also faster...get a good tune and listen for ping...if you don't hear it ping you are prolly good to go...don't be afraid to run the **** out of it to help it break in (after initial heat cycling it), it will help the rings wear into the cylinder walls and seal good...sportster motors a tough and take a pretty good pounding without breaking (kinda like a vagina)....your oil temps look fine, and maybe even a little cooler than to be expected...
