Attempting the oil mod on 83 interceptor, looking for expertise!

Mostly the time it takes me to deliver, and partially cost. In this case I don't stock the parts for the kits anymore which means I would have to buy a small quantity. That causes delays and makes the price go up a bit.

 

So tinkerinWstuff you live southern colorado?
Is an oil cooler a good idea (Jamie D.)?

 

way up north, well we may still pass each other someday

 

It certainly isn't a bad idea. I this is part of the reason the early VF's run so hot. That, and their undersized radiators.

 

Ill shoot you an email Jamie D

 

Oil Mod

Either of you two (Ronald/scario) choose to pursue this mod? I'll be curious to hear what you guys discover.

HI Guys
Have done the mod - with help from the local aerospace hose supplier (Berenpas in Holland)
-4AN fittings with SS braided -4 piping.
Went straight into the oil gallety with a AN banjo fitting, thread is 10mm x 1.1 if I'm not mistaken, will loctite the banjo in place once ready. The block that I have ('84) has the aluminium cast lug that I used for the thread. It did hoever require 'spot facing' so that the seal will be acceptable though and everything was using 'eyeball Mk1' (ever tried to get a complete VF block on a milling machine?! Will attach photo's if there is interest - snowing out though!!
In terms of restrictions - havent heard anything from Jamie yet - so am hoping the restriction of the piping, cam openings in the head, etc. are sufficient to leave a little pressure for the big end?!!
Regards
Ronald

 

Your wish, is our ....
Flow should be good, biggest worry is that there will be a too great a drop in the crank gallery... hence my question as to the restriction size.
Measuring flow also a good suggestion however as you can see the block is stripped out the bike and therefore pretty difficult to determine at this stage.

Hey Ronald - What I think you are going to find is that the banjo fitting going to the front head will interfere with the linkage on the carbs. You need to run it above/in front of the carb insulator. It will come in straight from the side and into the V first. In order to make this work you must raise up the banjo fitting ~10mm. What I used in my kits was a spacer that was the same thickness as a banjo bolt along with a double banjo bolt. That works like a charm.

You will want to incorporate a restriction for sure. I'd suggest starting with something around Ø2-2.5mm. Check pressures before the mod and after and make adjustments as needed.

 

Hi Jamie
Thanks for the advice
Havent had the carbs back on yet so will keep the clearance in mind.
Thanks for the indicative hole size - will push a bronze bush into the lower banjo and drill a 2.2mm hole in as a restriction.
Regards
Ronald

 

I think the interference will become obvious once you do!

 

All that you really need to do is drill the mail oil gallery first then install a pressure gauge. Measure the pressure cold, hot, idle, at xxxx rpm, etc with the stock configuration. Then when you install the oiling mod you can compare the new values to the old. Then you can see if there is any differences in the bottom end pressure that need to be corrected for.

 

Just had a quick look and placed the carbs loosely
It seems as if this will increase the clearance (routed around the other side of the coolant pipe) - previous routing would have cleared but this is probably safer.
Banjo itself is bent inwards / downwards - so this also improves the clearance - even with the the carb insulator it should fit.
Also bear in mind that these are crimped (swaged) pipes - so less 'bulky' than the removable fitting fitted ones.

Cool - too bad I already tossed the old oil pipe :-(

 

The throttle wheel will probably hit the banjo fitting. You need to install the carbs completely to see what I mean, but I still think you will need to move the line in front of the carb. Maybe not, but check it closely now while it's still easy to change it.

 

Scratch that! I thought yours was a VF500, I got confused. You should be just fine.

Have just measured the bottom banjo internal hole with my 'very-near' - near as dammit is to spitting 2,9mm - think I will leave it as it is and take a chance
