Bandit Head Cooler Help!!

[1340banditpaul]

Won't fit at front anywhere,  won't fit under engine near shock, no room under back seat, only other place is where Lee has his on his yoshi 1340 gsxr where the reg plate is but it'd be headache routing hose plus exhaust is under seat. 

I'm regretting going bigger engine and wish I'd of gone turbo route instead now, easier and probably cheaper lol.

in general more power = more heat. A turbo is just another way to make more heat.

Yep. Whatever you do results in more heat. You would still need to upgrade cooling if you want to use a turbo bike for more than pub points

Back in the day, saw a few mounted up beside number plate....might look bit odd on yours though.

Your right, I've just got to a stage where I solve a problem and create another and this cooling problem is stressing me out, I will sort it though (and probably create another problem lol)

Cheers for all the input everyone has given and I do appreciate it.

I'd definitely duct some cool air to the cooler. 

Wouldn't be my choice of position  personally.

Sort of agree with that - its a low pressure area and airflow is a bit strange hence why open carbs work peculiar. Personally I'd up the main cooler size and maybe change the oil more frequently?

Ii ssuppose with a turbo, riding off boost the motor actually generates less heat than n/a. A big bore and high comp motor just makes more heat all the time.

Even if you didnt have any ducting cooler behind carbs would be an improvement, just not as much as with good airflow to it.

Just out one interest do you find the oil drains from the cooler over time - making oil height measurement an issue for the engine when it's sat for a while?

[fatblokeonbandit]

Nope, run it leave for a couple of minutes and check the oil level, havent noticed any increase due to drainning

[Gixer1460]

Again - the oil can't drain out of a cooler with connections on the lower side UNLESS you drain the sump! Only when the crankcase hose connections are uncovered can air enter to break the vacuum created when cooler is full.

I thin k he meant the head cooler not the main one

[markfoggy]

Thinking outside the box.....Can you do anything with something like this

keep your shocker warm, solve one problem, create another, shock cooler anyone?

What state of tune is the engine ?   and what use is the bike going to have - this will decide what extra cooling you'll need. A naked is always going to run cooler than a faired bike - you could piggy-back the coolers in the std position if there's room. Taking out a bit of ignition advance will make it run cooler too.  Dunno, just thinking out loud

I have a 1216 High compression .. just going through this myself. Just bought a 19 row earls. If that is not enough, I thought perhaps the 13 row original might fit in front of the 19 as an option. First step is to see if the 19 row works I guess. I also assume if you run fully synth, then the oil will last longer over mineral and semi. 

The following is mineral oil failure at temperature over mileage - semi is better, and full synth is better still. Reading between the lines, oil (mineral, works well enough)  up to 250F (120C) - you could expect significant oxidation by 2000 miles at 120C! Above that temperature then it degrades very quickly. So fit a temperature gauge,.

I’m running a 19 row cooler on my Turbo Bandit powered ET, with no issues.

Yup @MeanBean49 said something similar. Though high comp engines make heat all the time - whereas turbos generate most on boost. We’ll see - sure it will be fine. If not - there’ll Be a solution.

Just change your oil regularly,it’ll be fine.

The reason I run a head cooler has nothing to do with oil life.  It's all down to power.  These engines use oil to cool the combustion chamber. cooler cylinder head the more compression and advance you can get away with.  

Even on my stock motor I see gains from the reduced heat soak around the inlets giving me a denser air fuel mix and more power.

[Dezza]

Looking at the bike, if a head cooler is necessary then something else on the bike is going to need to be modified to allow this to happen. Either using a different headlight set up to allow for a cooler up front or using a conventional exhaust so an underseat cooler can be used could be the way to go here, but the seat unit may have to be changed too as it looks fairly small. As an alternative, maybe 2 coolers mounted longditudally, one either side of the bike, would work. Like the radiators on a Gurls blouse SP2 or some of the aftermarket Yoshimura coolers for GSXRs that went under the fairing.

You could free up some space for a cooler by ditching the huge breather catch tank.

[dupersunc]

As I've said before. mount a head cooler bellow the existing oil cooler, like they did on the GSXr750rrk and just about every modern 1000cc sports bike.

[bluedog59]

If those USD forks are shorter than stock, running one below the main cooler may present clearance issues.

Even if I removed the catch tank and relocated it somewhere else or put a smaller 1 on, with already having an extra wide cooler fitted, putting a head cooler on the side of the extra wide cooler it would stick out too far.

Wanted to put a cooler below the other cooler but like you say, the forks are short and will hit the cooler, might have to get yokes stepped to make them longer.
