(In this case, these last two reasons for the “filter pointing down” design really don’t apply since the filter mount and filter are disassembled/assembled off the bike.)Ĩ) Be hidden from view as my bike is stock and I want to keep that look.

This also allows for cleaner used filter removal, plus I want to completely pre-fill a new oil filter before screwing it on as lubrication to the rocker gear is after the filter (see oil line diagram). No chance of engine oil starvation: For this reason, I wanted the filter to be in the oil return line, which is virtually the standard convention when adding engine oil filtration on classic Triumphs.Ĥ) Uses inexpensive, readily available oil filters.ĥ) Does not require any modifications to any of the original parts of the motorcycle (e.g., drilling holes, cutting metal).Ħ) Will not interfere with servicing/accessing any other part(s) will not potentially rub other parts.ħ) A “filter pointing down” design so as not to just depend on the anti-drain-back valve in the filter. If it’s a 500 (or any size other than a 650), find out if the oil line routing is the same or different from what I’ve illustrated for a 650 before proceeding.ġ) Oil filtration efficiency that is at least equivalent to today’s car engines.Ģ) Extremely reliable design: No chance of things shaking loose, hoses coming off or prone to leaking oil.

Assess for yourself if your bike is different, such as you want to install on a 650 with a single carb (air filter clearance?) or a 500 cc machine (overall clearance of parts?). Please note that this is for a 650 with the original twin carb/air filters setup. I’ve always intended to share this design with others so that they may duplicate or maybe even improve on the design, but I’ve only just now gotten around to doing that, so this will be a test of my memory. This was 3 years ago and maybe there are some better kits available now – I’ve had no reason to keep looking. I looked around on the internet but didn’t see any kits that I felt were satisfactory, so I decided to create and install my own design. Hello everyone, I’ve just become a member of The Triumph Forum and this is my first post I hope I can do it properly.Īs all of us owners of old classic Triumphs know, these motorcycles desperately need some decent engine oil filtration, and several years ago I decided I absolutely needed to install something on my ’68 Bonneville.
